Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1135 PM CST Fri Dec 29 2023

Valid 301200Z - 311200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Little chance of thunderstorms will exist across the country today.

...Synopsis...
An amplified upper-air pattern will persist today, with a trough
exiting the East Coast, and another dropping south over the upper MS
Valley. At the surface, relatively stable air will exist due to high
pressure and offshore winds over the Gulf of Mexico and western
Atlantic. 

To the west, a highly amplified upper trough near the West Coast
will move east, eventually reaching UT/AZ early Sunday. While cool
midlevel temperatures will exist beneath this trough, winds veering
to westerly with its passage will result in downward motion and
drying across much of the region. Precipitation chances will be
maximized early in the day, and forecast soundings indicate little
instability present to support thunderstorms within the north/south
oriented precipitation band which is forecast to dwindle. 

As such, less than 10% thunderstorm probabilities are forecast for
today.
