These webinars are peer-to-peer learning with staff from WFOs, National Centers, CWSUs, and RFCs leading the presentations. The presentations are short (less than 30 minutes) and offer recent in-season examples ready to apply operationally. The primary objective of these webinars are to share how to apply GOES imagery with other datasets for a specific operational application so that other WFO’s learn how to do this.

A Not-So-Elevated Supercell from Eastern Iowa to the Chicago Area on 4 April 2023 | 2024-04-17 | Peter Speck discusses an intense supercell thunderstorm with largely elevated characteristics that formed early on the morning of 04 April 2023 in southeast Iowa, and thereafter took a 200+ mile long track that included parts of two major metropolitan areas over the next seven hours. This supercell alone produced significant severe weather along much of its path, including a swath of over 150 large hail reports ranging from one to nearly four inches in diameter, severe wind gusts reaching 90 MPH, and multiple short-lived tornadoes. For such a long-lived storm, the meteorological impetus for this development was subtle, with possibly gravity waves playing a role. Satellite analysis was one means that may have helped identification of these, and this will be explored. | |

While impacts across the NYC metro were significant, no fatalities were reported. This presentation will examine the challenging forecasts and messaging leading up to the event, along with a focus on satellite information used at WPC for generation of the Mesoscale Precipitation Discussions (MPDs), and at WFO New York, NY for flash flood warning issuance. | |
A Climatologically Rare November Morning Hailstorm in Southwest Lower Michigan: Using the Airmass RGB to Diagnose an Intense, Localized PV Intrusion | 2023-12-13 | T.J. Turnage discusses a thunderstorm complex that produced hail up to 1.5 inches in diameter just north of Grand Rapids, MI on the morning of November 6, 2023. This is a very rare time to experience severe weather in Lower Michigan and this particular event turned out to be the only severe weather of the day across the entire CONUS. The GOES-East Airmass RGB provided a clear depiction of a sharp, narrow PV intrusion that quickly contributed a significant amount of shear and conditional instability to Southwest Lower Michigan, making conditions much more favorable for severe weather. This case illustrates how the Airmass RGB might be used to identify situations in which environments could rapidly change to become supportive of severe thunderstorms. | |
A Convective Application of Synthetic Aperture Radar (SAR) Winds Over Lake Superior on 5 September 2023 | 2023-10-04 | Patrick Ayd discusses the severe convective event of September 5, 2023 over western Lake Superior. As a line of convection was propagating across the western third of Lake Superior, a SAR Wind pass sampled the line of convection. The timing of where the convection was over the lake and the SAR pass also coincided with in-situ wind measurements on the tug-barge Dirk S. VanEnkevort with a gust to 61 kts recorded and relayed in near real time to NWS Duluth operations via communications with the NWS Great Lakes Port Meteorological Officer (PMO). Mesoanalysis, radar and satellite analysis of the event will be presented, and future applications of polar orbiting needs for the Weather Forecast Office (WFO) will be discussed. | |
An Operational Review of the 1 May 2023 Localized Blowing Dust Event Across South-Central Illinois | 2023-06-28 | James Auten and Marshall Pfahler discuss a blowing dust event in Illinois from 1 May 2023. Two narrow plumes of blowing dust in south-central Illinois resulted in localized near-zero visibilities, causing multiple vehicle accidents and pile ups on I-55 near the Sangamon-Montgomery County line involving 72 vehicles in total with seven fatalities and 37 injuries. These plumes of blowing dust emanated from freshly tilled and planted farm fields with unseasonably dry soils, carried downwind by northwesterly winds gusting from 35 to 45 mph. This presentation will discuss the antecedent conditions, synoptic-scale weather pattern, application of the GOES-16 Dust RGB product, and warning/advisory product decisions along with a comparison to another localized blowing dust event on 2 May in the same area. | |
An Unusual Mid-Winter HSLC Event Across Northern Ohio on January 19, 2023 | 2023-03-23 | Doug Kahn discusses the 19 January 2023 High CAPE Low Shear severe thunderstorm event over northern Ohio. On January 19, 2023, a potent, closed upper-level low and associated surface cold front moved east across the Lower Great Lakes region. A line of low-topped thunderstorms developed along the cold front during the afternoon and evening hours in an HSLC environment.

Assessment of profiles in NSharp, or even the quick-look pop-up Skew-T, provides forecasters with extra insight in the changing convective patterns of tropical disturbances or the convectively-inhibiting trade-wind inversions. Additionally, gridded NUCAPS data available both in AWIPS and via the NASA SPoRT (Short-term Prediction Research and Transition Center) web viewer provide forecasters a plan-view option to assess NUCAPS data by pressure level and pressure layer. | |

An Operational Review of the Historic Waverly, TN Flash Flooding | 2021-09-22 | Matt Reagan and Brendan Schaper discuss the historic flooding event of August 21, 2021, the deadliest flash flood on record in Middle Tennessee. An event of this magnitude is uniquely challenging to predict and an even greater challenge to communicate. Through observational data and model output, forecasters at the National Weather Service in Nashville, Tennessee identified a stationary boundary with an exceptional moisture profile as the potential focus for heavy rainfall. Radar and satellite data during the event, such as the Multi-Radar/Multi-Sensor System (MRMS), provided important details that allowed forecasters to issue a Flash Flood Emergency across a four-county area Saturday morning. A preliminary review of model performance, radar, and satellite observations suggest that the combination of forecaster interpretation and information available before and on August 21st were paramount in detection, warning, and communicating the life-threatening situation. | |
Forecasting Heavy Rainfall in American Samoa with no Radar | 2021-09-08 | Dora Meredith discusses the challenges of forecasting heavy rainfall in American Samoa without the benefit of radar data. With the lack of radar technology, the WSO Pago Pago staff relies heavily on satellite observations, upper air soundings, and model data to run its operations. GFS potential temperatures and relative humidity patterns, as well as the Galvez-Davison Index model output are found to be dependable tools for forecasting heavy rainfall conditions in the tropical region. These conditions include: abundant atmospheric moisture, a lifting mechanism, and instability. For this presentation, we will focus on utilizing MMIC Total Precipitable Water and other satellite features in combination with model data to assess and forecast the aforementioned conditions for American Samoa. | |
