Day 4-8 Outlook

Day 4-8 Convective Outlook  
NWS Storm Prediction Center Norman OK
0339 AM CST Wed Dec 18 2024

Valid 211200Z - 261200Z

...DISCUSSION...
Strong surface high pressure and a dearth of boundary-layer moisture
will preclude severe thunderstorm potential on Days 4-5/Sat-Sun. 

By Day 6/Mon, medium range forecast guidance shows a series of upper
shortwave troughs shifting east from the Rockies to the MS Valley
through Day 8/Wed (Christmas Day). In response, lee
troughing/surface low developing is expected over parts of the
southern Plains. Increasing southerly low-level flow will support
modest northward transport of Gulf moisture across parts of TX into
OK, and eventually the Lower MS Valley near the end of the period.
While there is still quite a bit of spread with regards to
intensity, location, and timing of these features, increasing
thunderstorm activity is expected Day 6-8/Mon-Wed across the
southern Plains vicinity. While uncertainty is high, if timing and
overlap of key features comes to fruition, some severe risk could be
possible over the upcoming Christmas holiday period.
