Day 4-8 Convective Outlook 
NWS Storm Prediction Center Norman OK
0251 AM CST Sat Jan 11 2025

Valid 141200Z - 191200Z

...DISCUSSION...
Strong surface high pressure and a dry/stable airmass will envelop
much of the CONUS through Day 6/Thu. By the end of the period around
Day 7-8/Fri-Sat, medium range guidance indicates a shortwave upper
trough may move across the southern Plains and Southeast. As this
occurs, a deepening surface cyclone will develop over the southern
Plains and shift east. Strengthening southerly low-level flow ahead
of the surface low will allow for Gulf moisture to return northward
across portions of south/east Texas into the Gulf coast states. Some
severe thunderstorm potential could acco*pany this system at the end
of the forecast period. However, uncertainty and spread in forecast
guidance with regards to timing/track of the surface low, and
moisture return across the Gulf coast region, precludes severe
probabilities at this time.
