Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0656 PM CST Sun Dec 22 2024

Valid 230100Z - 231200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not forecast across the contiguous United
States through tonight.

...Synopsis...
An upper trough currently exists along the coastal Pacific Northwest
this evening, and height rises will occur tonight as the wave moves
northeastward across OR and WA. In the near term, a few
thunderstorms will remain possible over coastal northern CA, and
farther north across western WA beneath the cooler air aloft. Most
of the instability is elevated over southern areas, but weak SBCAPE
may exist near coastal WA. Here, low-level flow will veer to
westerly coincident with the stronger midlevel cooling, supporting
non-severe, low-topped convection.
