After a cool start to the work week, temperatures increased each day through the first half of the weekend. Temperatures by Friday and Saturday were well into the 60s with some locations even hitting 70. Paintsville owned the highest reading at 75 degrees. Much of the work week consisted of mostly dry conditions until the pattern changed dramatically Thursday night and heading into the weekend as a cold front stalled just north and west of the state. Multiple waves of low pressure rode along this boundary and resulted in an unseasonable, prolonged period of rainfall. Widespread showers brought extremely high rainfall totals, especially in western portions of the Commonwealth. Some locations recorded more than 4 inches in a 24 hour period, which is normally only seen once every 5 years. Overall, the state averaged 1.94 inches for the weekend, which was over an inch and a half above normal. In addition to the heavy rainfall, an unstable atmosphere Saturday night produced a line of storms pushing through the state. Damaging winds were reported across the area with even a weak, isolated tornado in Taylor County. Some wind gusts were even recorded at around 70 mph.

A reinforcing cold front on Wednesday was then followed by Arctic high pressure pushing into the region for the second half of the work week. Areas mainly in the northern portions of the state had more snow-cover and resulted in much cooler temperatures compared to southern Kentucky. Temperatures Wednesday night dropped into the single digits and lower teens for much of the state. Henderson even got down to a low of -1 degree. Wind chill values dropped well into the single digits, approaching 0 at times, which pushed the livestock cold stress index into the emergency category. The work week then ended with a low pressure system heading northeastward into the Ohio Valley. This system ended up producing a wintry mix across the Bluegrass State Friday night and into Saturday. Much of the eastern half of the state saw at least a quarter inch of precipitation. Temperatures for the period averaged 31 degrees across the state which was 8 degrees cooler than normal and 12 degrees cooler than the previous period.

Kentucky was above normal in rainfall for the 5th straight week, as on average, 1.38 inches fell across the state. The last time that the Bluegrass State has seen a wet period to this extent was back at about this same time in 2011. Throughout the week, there was isolated to scattered rainfall on nearly a daily basis. The first half of the work week was dominated by cloud cover and rainfall rotating around a pesky upper level low traveling up the mid-Atlantic Seaboard. This was then followed by a cold front pushing through the area over the course of Friday. This system brought the most widespread coverage for the week with over an inch falling across much of central Kentucky and into the Bluegrass. The cold front eventually swept through the area later Friday night, but was then followed by a weaker, reinforcing cold front Saturday evening. Scattered showers were once again evident, but the bigger headline was cooler temperatures. After hovering in the 70s and at times, 80s throughout the week, Canadian high pressure bumped highs back into the upper 50s to low 60s for Sunday. Temperatures for the period averaged 61 degrees across the state which was 1 degree cooler than normal and no change to the previous period. High temperatures averaged from 72 in the West to 68 in the East. Departure from normal high temperatures ranged from 4 degrees cooler than normal in the West to 7 degrees cooler than normal in the East. Low temperatures averaged from 53 degrees in the West to 51 degrees in the East. Departure from normal low temperature ranged from near normal in the West to 4 degrees warmer than normal in the East. The extreme high temperature for the period was 83 degrees at BOWLING GREEN APT and the extreme low was 35 degrees at Cynthiana 8N. Precipitation (liq. equ.) for the period totaled 1.38 inches statewide which was 0.28 inches above normal and 126% of normal.

Over these past 4 weeks, Kentucky has been over 2 inches above normal. Most of the rainfall this past period could be attributed to an upper level low over the weekend. This very slow moving system pulled large amounts of moisture from the Gulf of Mexico and the Atlantic Ocean as it progressed eastward. Throughout the weekend, the low provided over 1.5 inches of rainfall on average across the state with the most coming across central portions of the Commonwealth. While the period was wet, the start of the work week was dry as surface high pressure nosed into the Bluegrass State. Mostly clear skies were common with highs back into the upper 70s to low 80s. It was not until Saturday and on into Sunday that cloud cover kept temperatures below normal and thus, the Bluegrass Stated ended the week 2 degrees above normal. Temperatures for the period averaged 62 degrees across the state which was 2 degrees warmer than normal and 8 degrees warmer than the previous period. High temperatures averaged from 71 in the West to 72 in the East. Departure from normal high temperatures ranged from 3 degrees cooler than normal in the West to 1 degree cooler than normal in the East. Low temperatures averaged from 51 degrees in the West to 52 degrees in the East. Departure from normal low temperature ranged from near normal in the West to 7 degrees warmer than normal in the East.

Saying this, the week started off with high pressure to the east and an approaching cold front to the west. Southerly flow kept temperatures in the upper 60s to lower 70s. It was not until Tuesday evening and into the overnight that the boundary passed through the region. Rainfall amounts averaged over a half inch across the state during this event. Conditions dried out for the remainder of the work week as surface high pressure nosed into the region, but with much cooler temperatures. Clear skies and nearly calm winds created ideal conditions for frost Thursday and Friday morning. The most extensive coverage was seen Thursday as some locations even saw low temperatures drop into the upper 20s. The second round of rainfall came Friday and lasted through the weekend as a slow moving upper level disturbance passed over the Bluegrass State. This brought on and off periods of showers across Kentucky with an average of just over an inch. Highs stayed mainly in the 60s and assisted in leading to the first week of below normal temperatures since the start of the month. Temperatures for the period averaged 54 degrees across the state which was 4 degrees cooler than normal and 6 degrees cooler than the previous period. High temperatures averaged from 64 in the West to 66 in the East. Departure from normal high temperatures ranged from 8 degrees cooler than normal in the West to 5 degrees cooler than normal in the East.

A surface frontal boundary crept south on Tuesday bringing a round of thunderstorms across primarily the northern half of the state. Some even reached severe limits with damaging winds and large hail the primary threats. Later in the day Wednesday, a developing low pressure system then pushed this boundary north as a warm front. Thursday became the warmest day of the period behind breezy southerly flow. Highs rose into the low 80s across the Commonwealth with numerous wind gusts over 40 mph. As the day wore on, a strong cold front approached from the west and eventually pushed through western portions of the state Thursday evening and exiting Kentucky later in the day Friday. Through its passage, it slowly weakened across the state. Western portions saw the most rainfall with areas averaging more than 1.5 inches, before tapering to less than an inch farther east. Noticeably cooler air filtered into the Ohio Valley following its passage. Highs in the 50s were common on Saturday with patchy frost across the state that morning as winds became calm, skies cleared, and lows got into the low to mid 30s. Temperatures for the period averaged 60 degrees across the state which was 4 degrees warmer than normal and 2 degrees cooler than the previous period. High temperatures averaged from 71 in the West to 73 in the East. Departure from normal high temperatures ranged from 1 degree warmer than normal in the West to 4 degrees warmer than normal in the East. Low temperatures averaged from 51 degrees in the West to 49 degrees in the East.

First, after going 9 straight weeks with below normal temperatures, the Commonwealth finally broke the cool spell and was above normal for the first time since mid February. Breezy southerly flow for much of the week pushed temperatures into the 70s and at times, low to mid 80s. This came as the state was sandwiched between high pressure along the east coast and an approaching area of low pressure from the west. Lexington even broke a record high on Wednesday when it got to a high of 84. Secondly, the state rebounded from a 2 week dry period, where the state averaged over an inch of rainfall through the week. Over the period, the west did see the most rainfall with an average of 1.78 inches. Most of this came over the course of Wednesday and into Thursday as a line of showers with embedded thunderstorms brought widespread soaking rainfall across the Ohio Valley. Behind the line, a cold front swept through the state sending temperatures plummeting. Westerly flow put temperatures only in the mid 50s to low 60s for Friday and Saturday with patchy frost each night for mainly sheltered and low lying areas. Temperatures for the period averaged 61 degrees across the state which was 6 degrees warmer than normal and 12 degrees warmer than the previous period. High temperatures averaged from 72 in the West to 75 in the East. Departure from normal high temperatures ranged from 4 degrees warmer than normal in the West to 8 degrees warmer than normal in the East. Low temperatures averaged from 50 degrees in the West to 50 degrees in the East.

Saying this, it was still not enough to overcome cooler temperatures earlier in the period and Kentucky witnessed its 7th straight week of below normal temperatures. The week started off with a weak cold front moving through the area with breezy northwest winds and cloud cover limiting temperatures to mainly the mid 40s to mid 50s. High pressure then eventually followed with an extremely dry air mass in place. Relative humidity values dropping into the 20s on Tuesday and Wednesday afternoons were common. Thursday was the only real shot at precipitation as an upper level trough passed through the region. The main focus was across the southern portion of the state, where widespread light rainfall was evident. As high pressure returned over the Commonwealth on Friday, temperatures returned to near normal levels. On Saturday, the combination of this high to the east and a low to the west situated Kentucky in strong southerly flow. Highs over the weekend peaked in the low to mid 70s each day. Temperatures for the period averaged 48 degrees across the state which was 4 degrees cooler than normal and 6 degrees warmer than the previous period. High temperatures averaged from 61 in the West to 59 in the East. Departure from normal high temperatures ranged from 5 degrees cooler than normal in the West to 6 degrees cooler than normal in the East.

While the state did see highs back into the lower 60s by the weekend, it was not enough to offset highs earlier in the week in the mid 30s to low 40s. Overall, the Bluegrass State ended the week on average, 9 degrees below normal. Normal highs for this time of the year are supposed to be in the low to mid 60s. While it was cool, Kentucky finally saw some dry conditions. Only a few notable systems passed through the state over the course of the week. The period started off with a surge of snow showers along the backside of a low pressure system moving through the area on Monday. Although there were some heavier snow bands, surface temperatures kept any accumulations to a minimum. An upper level disturbance then passed through on Friday across mainly western and central portions of the Commonwealth, just before a more statewide event Saturday night. Over the course of the weekend, the state averaged 0.33 inches with higher totals out west. The rest of the week was dry with surface high pressure in place and resulted with the state below normal by a half inch. Temperatures for the period averaged 41 degrees across the state which was 9 degrees cooler than normal and 2 degrees warmer than the previous period. High temperatures averaged from 51 in the West to 48 in the East. Departure from normal high temperatures ranged from 12 degrees cooler than normal in the West to 14 degrees cooler than normal in the East.

It was a very cold and wet week across the Commonwealth with temperatures averaging 9 degrees below normal, making this the 5th week in a row with below normal temperatures. The period started off with a strong cold front pushing through the region with nearly all locations seeing at least an inch of rainfall. Another reinforcing cold front swept through the Commonwealth on Wednesday. This was mostly a dry passage with its main effect on temperatures. Lows on Wednesday and Thursday night each dropped unusually low with temperatures in the upper teens and low 20s. Some locations in the east even dropped into the low teens. Normal lows for this time of the year are in the upper 30s. Other than some weak upper level waves, the rest of the week remained fairly dry until late in the weekend with the passage of another area of low pressure. This brought another half inch on average across the state, which put totals for the week just under 2 inches. Temperatures for the period averaged 39 degrees across the state which was 9 degrees cooler than normal and 6 degrees cooler than the previous period. High temperatures averaged from 47 in the West to 48 in the East. Departure from normal high temperatures ranged from 14 degrees cooler than normal in the West to 12 degrees cooler than normal in the East. Low temperatures averaged from 32 degrees in the West to 29 degrees in the East.

Over the course of the week, the state averaged 1.33 inches, which was 0.35 inches above normal. The wet week started off with a slowly progressing cold front moving through Kentucky on Monday. Averages near an inch were common with its passage. Numerous upper level disturbances then sparked scattered snow showers the next couple days, but no accumulations were evident. Dry conditions eventually moved in for the remainder of Wednesday with highs only getting into the 30s with breezy conditions. These temperatures helped in leading Kentucky to its 4th straight week of below normal temperatures. Winds shifted to southwesterly on Friday along a warm front, acting to put temperatures into the upper 60s to lower 70s by Saturday, but this was short-lived. A surface low tracking just north of Kentucky sent a cold front through the area with highs on Sunday only getting into the 40s. Another surface boundary then lifted from the south on Sunday providing another round of precipitation with just under a half inch statewide. Temperatures for the period averaged 44 degrees across the state which was 2 degrees cooler than normal and 4 degrees warmer than the previous period. High temperatures averaged from 54 in the West to 54 in the East. Departure from normal high temperatures ranged from 5 degrees cooler than normal in the West to 4 degrees cooler than normal in the East. Low temperatures averaged from 35 degrees in the West to 36 degrees in the East.

The week started off with unseasonably cool temperatures in place. Highs only crept into mainly the mid 40s to low 50s Monday and Tuesday before only getting into the 30s on Wednesday. Over the course of Tuesday night and into Wednesday, an area of low pressure placed anywhere from a trace to 3 inches of snow across the Commonwealth. Higher totals of 2 to 3 inches were situated in the northern Bluegrass. These slowly diminished to just a trace to 1 inch farther south. Surface high pressure and upper level ridging then moved in later in the work week and into the weekend. Temperatures became very mild by Saturday and Sunday as the state was under gusty southerly flow. As a precursor to a cold front moving through the area Sunday night, temperatures warmed into the upper 60s to lower 70s statewide. Temperatures for the period averaged 41 degrees across the state which was 4 degrees cooler than normal and 4 degrees warmer than the previous period. High temperatures averaged from 53 in the West to 49 in the East. Departure from normal high temperatures ranged from 4 degrees cooler than normal in the West to 7 degrees cooler than normal in the East. Low temperatures averaged from 35 degrees in the West to 30 degrees in the East. Departure from normal low temperature ranged from 0 degrees from normal in the West to 1 degan normal in the East. The extreme high temperature for the period was 78 degrees at PAINTSVILLE 4W and the extreme low was 14 degrees at CYNTHIANA 8N.

The state only averaged 0.69 inches, with most of it coming at the start of the week as a low pressure system pushed northeastward into the Bluegrass State. Rainfall totals were around a half inch with its passage. An upper level low kept the Commonwealth in northwesterly flow for much of the latter half of the work week and into the weekend. Multiple pulses of energy swept around this system, bringing on and off chances of light snow and rain accumulations. Dense cloud cover stuck with the Commonwealth for much of the week, keeping highs in the 30s. Normal highs for this time of the year are in the lower 50s. After the cool and dreary week, the skies finally became mostly clear on Sunday as weak surface high pressure descended over the state.

Although the week was mostly dry, plenty of focus was given to a low pressure system pushing through the region on Wednesday and into Thursday. Temperatures fluctuated greatly across the state making for multiple forms of precipitation falling across the Commonwealth. Cooler temperatures led to a wintery mix of sleet and freezing rain in western portions of the state and wrapping around the northern periphery of Kentucky. Areas south remained warm enough for all precipitation to remain as rainfall. Soon after its passage, a warm front pushed through the state and put temperatures back into the 50s for Friday. This was the general trend going into the weekend with surface high pressure providing dry conditions, clear skies, and temperatures hovering around normal. Tempehe period averaged 37 degrees across the state which was 2 degrees cooler than normal and 2 degrees cooler than the previous period. High temperatures averaged from 45 in the West to 49 in the East. Departure from normal high temperatures ranged from 7 degrees cooler than normal in the West to 2 degrees cooler than normal in the East.

This made for the 5th week of 2013 with below average precipitation. Much of the week was dominated with high pressure in place, which acted to provide dry and quiet conditions. The only notable precipitation events happened on Wednesday and Friday. The first system had a heavy band of snow, which gave way to totals in excess of an inch in central and bluegrass portions of Kentucky, but warmer temperatures led to rapid melting through the afternoon hours. The other system was associated with a weak surface cold front extending into the Bluegrass State on Friday, bringing a light mix of rain and snow showers. Temperatures fluctuated throughout the week, but averaging highs and lows for the entire period led to temperatures right around normal for this time of the year in the mid to upper 30s. Temperatures for the period averaged 38 degrees across the state which was 0 degrees from normal and 4 degrees cooler than the previous period. High temperatures averaged from 48 in the West to 45 in the East.

In regards to rainfall, Kentucky stayed fairly dry with only a few minor systems moving through the Bluegrass State. The most significant came over the course of Sunday with the movement of a front through the area. As the boundary passed through, western portions of the state benefited the most with just under a half inch of rainfall, but this amount tapered off to around a tenth of an inch to the east. Although the state as a whole was below normal for the 4th time this year, Kentucky is still above normal for the year by 0.82 inches.

Earlier in the work week, a low developed and moved north of the Commonwealth with a strong cold front dragging behind. Ahead of the front, strong southwesterly flow pushed highs into the upper 60s and lower 70s through the start of the work week. Throughout the path of the low, rapid intensification took place and resulted with a powerful line of strong to severe storms moving through the Bluegrass State. Widespread damage was observed across Kentucky, with most reports credited to high winds in excess of 70 mph. Tornados were also a problem. An EF2 tornado was reported just east of Bowling Green with winds around 120 to 125 mph. Cooler temperatures returned by late in the work week with highs Friday mainly in the 20s. The last significant precipitation event for the week occurred on Saturday with an Alberta Clipper passing through the Bluegrass. Snowfall totals around 1 to 3 inches were numerous with its passage. Total precipitation for the week was over 1.5 inches statewide, which was just under an inch above normal. Temperatures for the period averaged 40 degrees across the state which was 6 degrees warmer than normal and 14 degrees warmer than the previous period.

Over the early portions of the work week, several systems acted to pull extremely cool air down from Canada. Most saw lows on Tuesday morning dip down into the lower teens with some even in the single digits. Highs Tuesday generally didn't get out of the low to mid 20s. The cold temperatures, combined with rather breezy conditions put the livestock coldstress index well into the danger and emergency categories. The only major precipitation event for the week was on Friday as a low pressure system passed to the south. This brought a mix of wintery precipitation to the region. Freezing rain was most prominent to southern Kentucky, with a transition to sleet and even some snow farther north. Ice accumulations of a quarter inch were numerous across the south. The weekend brought a return to pleasant conditions with high pressure in place. Temperatures slowly moderated into the 40s by Sunday. Temperatures for the period averaged 27 degrees across the state which was 6 degrees cooler than normal and 8 degrees cooler than the previous period.

Temperatures were only 2 degrees above normal, while rainfall was below normal by only around a tenth of an inch. The rainfall producers were mainly felt in the earlier portion of the work week. The most significant was the passing of a low on Tuesday night where many areas in central and Bluegrass portions of Kentucky saw a mix of wintery precipitation. Snow, sleet, and freezing rain were all evident. Warmer temperatures to the southeast kept most of the precipitation as rainfall. Dry with mostly clear conditions moved in by Friday as the Commonwealth was under the influence of surface high pressure. As this high meandered to Kentucky’s southeast Friday night and into Saturday, winds shifted to southerly and sent temperatures soaring across the region. Highs by Saturday were well above normal with highs topping out in the low to mid 50s statewide.

Temperatures for the period were 16 degrees above normal, but this is nearly an understatement in comparison to the weekend where an average deviation of 24 degrees above normal was felt across the state. Highs rose well into the upper 60s and at times, 70, as a near continual southwest flow of warm air pumped into the Commonwealth. Highs are normally only in the upper 30s to low 40s for this time of the year. Accompanying the warm air was an abundant amount of precipitation later in the work week and into the weekend as multiple waves of low pressure meandered through the Bluegrass State. Over the course of the period, the state saw an average of 2.6 inches fall to the ground. The west was the leader with more than 4 inches of beneficial rainfall following the drought of 2012. The states above normal deviation of 1.72 inches was exceptionally high, as the highest deviation Kentucky saw for the entire year of 2012 was only 1.38 inches back in September.

While most sections saw around a quarter of an inch with its passage, this event was the only major rainfall producer for the week. Most of the other disturbances were moisture starved and resulted in no significant precipitation. Surface high pressure moved in shortly after New Years, bringing rather quiet and dry conditions for a good portion of the week. After going through a wet December, Kentucky started 2013 with a state rainfall deficit of over a half inch. In addition to dry conditions, the Bluegrass State also saw cool temperatures as the area was 2 degrees below normal for the period. Highs were commonly in the upper 30s to lower 40s, with lows dropping into the low to mid 20s. Temperatures for the period averaged 32 degrees across the state which was 2 degrees cooler than normal and 2 degrees cooler than the previous period. High temperatures averaged from 39 in the West to 39 in the East.
