DISCUSSION

Issued at 133 PM CST Sun Nov 30 2025

Rain chances will remain medium to high (40-80%) through Monday as a coastal trough develops in the northwest Gulf and interacts with isentropic lift across South Texas. Rain chances will quickly taper off Tuesday as the coastal trough moves away from the region. Rain chances will increase back to medium to high (40-70%) chances mid- week as areas of positive vorticity advection move across South Texas ahead of our next cold front later in the work week. Below normal temperatures will continue through Tuesday with temperatures returning to near normal values by mid-week. Although temperatures will be below normal, overnight temperatures are expected to remain above freezing (32 degrees F). However, chilly temperatures combined with winds over 10 mph will lead to cold wind chill values (feels like temperature) Monday morning ranging between 33-40 degrees Monday morning and 31-40 degrees Tuesday morning.

AVIATION

(00Z TAFS) Issued at 534 PM CST Sun Nov 30 2025

MVFR ceilings blanket South Texas, with slightly higher VFR ceilings around 3-4kft near the Rio Grande (LRD/COT). North to northeasterly winds around 12 knots early this evening will diminish overnight. Conditions will deteriorate overnight into the morning hours Monday as ceilings drop, bringing IFR/LIFR over Coastal sites (ALI/CRP/VCT) and a medium to high chance for showers. Rain chances will diminish by the afternoon but can expect MVFR vsby reductions with direct shower impacts. Ceilings improve to VFR out west over COT/LRD by the afternoon. Winds will remain light out of the north to northeast tomorrow.

MARINE

Issued at 133 PM CST Sun Nov 30 2025

A fresh to strong breeze (BF 5-6) will continue through Tuesday before weakening to a gentle breeze (BF 3) Tuesday night. Winds are expected to strengthen back to a fresh breeze by late this week. Medium to high (65-90%) rain chances will remain in the forecast over the Gulf waters through Monday night before rain chances quickly taper off Tuesday. Medium to high rain chance (60-90%) will return mid- week and continue through the end of the work week.

FIRE WEATHER

Issued at 133 PM CST Sun Nov 30 2025

Minimum relative humidity will remain above 35% through this week along with below normal temperatures Sunday through Tuesday following a strong cold front early this morning. Medium to high chances for showers are forecast through Monday. A brief lull in rain chances is expected after a reinforcing surge of high pressure pushes through late Monday night into Tuesday, but low to medium rain chances return Wednesday through Friday as additional disturbances arrive. There are no elevated fire weather concerns at this time.
