Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1003 AM CST Sun Dec 22 2024
Valid 221630Z - 231200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast across the contiguous United
States through tonight.
...Northern CA/Pacific Northwest coast through tonight...
Lightning flashes have been observed this morning within a
baroclinic band roughly 150 mi off the northern CA coast, in
association with a midlevel shortwave trough that will move inland
later today into tonight. The potential for isolated lightning
flashes inland will begin this afternoon with elevated convection in
the warm conveyor belt across northwest CA/southwest OR. Other
isolated lightning flashes may also occur this evening into early
tonight along the WA coast as steeper low-midlevel lapse rates and
weak buoyancy spread inland.
