Day 1 Convective Outlook

1127 PM CST Sun Dec 14 2025

Valid 151200Z - 161200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorm probabilities are low today.

...Pacific Northwest...

100+kt 500mb speed max is forecast to translate inland along the
WA/OR coast around 16/00z. Low-amplitude short-wave trough will
induce strong height falls near the international border ahead of
this feature, coincident with a notable surface front that will
surge inland after 21z. While profiles will cool and steepen at
midlevels, forecast soundings are not particularly buoyant either
side of the trough, and the prospect for deep convection capable of
generating lightning appears low. While the thunderstorm potential
appears low, weak midlevel convection is possible and a flash or two
can not be ruled out. This, however, does not warrant a categorical
risk for thunderstorms during the day1 period.

SPC Day 1 Fire Weather Outlook

Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1126 PM CST Sun Dec 14 2025

Valid 151200Z - 161200Z

...NO CRITICAL AREAS...

...Synopsis...
Cold air will continue to move into the Southeast today. Some dry
and breezy return flow is possible in the southern Plains, but cool
temperatures/higher RH will also be present. The most likely
location for localized fire weather concerns will be east of the
terrain in southeastern Wyoming. There, downslope warming and breezy
conditions supported by a weak lee trough and modest mid-level flow
will promote potentially elevated conditions. However, the
duration/intensity of those conditions is too much in doubt for
highlights.

Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1132 PM CST Sun Dec 14 2025

Valid 161200Z - 171200Z

...NO CRITICAL AREAS...

...Synopsis...
Some modest breakdown of the upper ridge across the CONUS can be
expected on Tuesday. A weak front will move out of the High Plains.
There will be some increase in mid-level winds across the Rockies as
well. Where sufficient downslope warming occurs within the
central/southern High Plains, fire weather could approach elevated
criteria locally. Confidence in location/duration are too limited
for highlights.
