Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0121 PM CST Sat Dec 20 2025
Valid 221200Z - 231200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected on Monday.
...Synopsis...
Upper-level ridging will continue across much of the CONUS on
Monday. A compact, moderately strong shortwave trough will move into
the Pacific Northwest by mid/late afternoon. As the surface high
continues to move south and east through the Mid-Atlantic, moisture
return will occur in the western/central Gulf Coast regions. Very
isolated thunderstorm activity could occur near the Texas Gulf
Coast, but this potential should be quite limited given ridging
aloft and weak low-level forcing. Within the coastal Northwest, cold
temperatures aloft are expected to support isolated, low-topped
thunderstorm activity late afternoon into early evening.
