DISCUSSION

Issued at 147 PM CST Tue Nov 25 2025

Tonight through Thursday Night...

Weather conditions will be generally quiet later tonight across our entire CWA. Overnight lows will dip into the upper 40s/low 50s areawide. Wednesday will remain quiet as near term guidance shows a strong frontal passage tracking southeast over our forecast area. Afternoon highs will peak in the upper 50s/low 60s areawide. Quiet and seasonably cooler weather conditions, 5-8F below, will occur across the southeast region late this week on Thanksgiving into late week (Thursday into Friday) thanks to mean northerly flow/subsidence, 1028-1032mb sfc high propagating southeastward across the area, and PW less than half inch.

Model consensus from both the GFS and the Euro are still showing tonight and Thursday night being the coldest periods with nighttime temperatures in the low to mid 30s. A couple of areas along and east of i-20 could see overnight lows drop to below freezing Thursday night, with a light frost/freeze possible by late Thursday night/early Friday morning timeframe. /CR/

Friday through next week Tuesday...

Quiet conditions will continue through Friday evening as the 1032 sfc high begins to propagate eastward towards the Carolinas. Looking ahead into the weekend, future guidance is still highlighting quite an active weather pattern developing over much of the central CONUS. A major longwave trough axis is forecasted to set over the Rockies into the Plains while a strong ridge builds up over the East Coast. This will help place our CWA in favorable deep southwest flow aloft for multiple rounds of showers and storms. At the moment, global models are still showing increasing potential for heavy rainfall to develop, with greater potential over the ArkLaMiss Delta region. Trends will continue to be monitored over the next several days. /CR/

AVIATION

(18Z TAFS) Issued at 1216 PM CST Tue Nov 25 2025

Local radar scans are currently showing scattered showers and storms over the east and southeast half of the area. As of 1812Z, GLH, GWO, GTR and HBG are reporting MVFR ceilings. GTR is currently under IFR ceilings due to -SHRA and a low stratus cloud deck. Conditions will begin to gradually improve to from the west this afternoon by 21Z Tuesday as the cold front continues to move east across the area. Ceilings will continue to improve to VFR by 23Z Tuesday and VFR ceilings will prevail through the end of the TAF period. Winds will be out of the west before shifting to the north by 06Z Wednesday. A brief period of low level wind shear will be possible across GTR between 08Z - 10Z Wednesday. /CR/
