Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0636 AM CST Thu Dec 19 2024

Valid 191300Z - 201200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected through tonight.

...Synopsis/Discussion...
The upper-tropospheric pattern is evolving back to an eastern mean
trough and western ridge for a few days, as a series of shortwave
troughs dig southeastward from the northern/central Plains and
upstream parts of western/central Canada.  Low-level cold frontal
passage related to the eastern troughing will render the airmass
east of the Rockies too dry and/or stable for thunderstorms over
land for the rest of this period.  Meanwhile, ridging aloft and lack
of greater moisture/instability will preclude thunder in the West.
