DISCUSSION

Issued at 119 PM CDT Sat Mar 21 2026

In the short term, patchy fog will be possible during the late night and early morning hours, particularly across the eastern Coastal Plains. Any reduced visibility will improve shortly after sunrise.

The main story through the weekend and much of next week continues to be well above normal temperatures under the influence of strong ridging aloft. Highs will range from around 80 degrees along the immediate coast to the mid- and upper 90s farther inland, with some locations approaching record values. Lows will generally be in the low to mid-60s inland and slightly warmer along the coast. By late Sunday into Monday, a weak cold front is expected to sag into central Texas before stalling north of the CWA. No precipitation is expected with this boundary. However, a slight weakening of the ridge combined with a weak mid-level disturbance over the western Gulf may result in a 2-3 degree decrease in temperatures Monday and Tuesday. By mid to late week, the ridge will reestablish itself as te Gulf disturbance weakens and shift eastward. Increasing low-level moisture will then set in, but rain chances are expected to remain negligible due to continued subsidence aloft. Temperatures will return to the upper 80s and 90s through the end of the week.

AVIATION

(00Z TAFS) Issued at 621 PM CDT Sat Mar 21 2026

VFR conditions prevail across South Texas. Brief periods of fog and LIFR/IFR ceilings could redevelop over the inland Coastal Plains between 10-14Z, mainly impacting ALI/VCT. Otherwise, VFR conditions will prevail through the forecast. South to southeasterly winds of 15-20 knots will diminish tonight to around 10 knots or less, then revamp Sunday afternoon to around 20 knots with gusts 25-30 knots.

MARINE

Issued at 119 PM CDT Sat Mar 21 2026

A moderate to fresh (BF 4-5) south-southeasterly breeze will persist the next couple of days before a light to gentle flow (BF 2-3) sets up on Monday and Tuesday. Conditions rebound to a gentle to moderate flow by midweek, continuing through to next weekend. Rain chances are expected to remain negligible at this time with wave heights between 2-4 feet.

FIRE WEATHER

Issued at 119 PM CDT Sat Mar 21 2026

Persistent ridging aloft will allow for abnormally warm conditions to continue across South Texas throughout the next week. Minimum relative humidity will consistently drop below 30% over the Brush Country each afternoon, with Energy Release Components (ERCs) in the 70-89th percentile and dry to critically dry fuels. Specifically today and Sunday, minimum relative humidity values may drop into the teens. With winds between 10-15 mph and gusts reaching 20-25 mph during the afternoon hours with the seabreeze, elevated fire weather conditions appear likely the next several days, especially across our westernmost zones. A Fire Danger Statement remains in effect for Jim Wells to Live Oak westward this afternoon and evening, and we will need to evaluate the need for one on Sunday during our next forecast package.
