KEY MESSAGES

- Warm and humid conditions continue today, then cooler than normal conditions this weekend into early next week after a strong cold front moves through.

- Dry today with rain chances through the weekend into next week as an active pattern returns.

SHORT TERM

(Today through Saturday) Issued at 1218 AM CDT Fri Apr 17 2026

Dry and mostly cloudy conditions are expected this morning with continued south to southeasterly wind over the region. An upper level trough deepens and digs into the Central Plains today which puts South Central Texas between a surface low to the northwest and high pressure to the east. This set-up with allow for breezy southerly wind today with gusts to around 25 mph most favored in the eastern half of the CWA. We should see some sunshine as well today as clouds scatter mid to late morning leaving afternoon highs warm in the upper 80s to mid 90s.

Wind relaxes late tonight as a cold front approaches our area from the northwest, which should be right on our doorstep sometime around sunrise to mid-morning on Saturday. The front moves across all of South Central Texas during the daytime making temperatures tricky with cloud cover and rain chances forecast behind the front given its gradual slope. Most guidance indicates afternoon temperatures to be in the 50s and 60s and did trend colder on Saturday than the NBM. Additionally, gusty northerly wind is expected behind the front aiding in the cooler temperatures with some guidance indicating gusts as high as 40 mph directly behind the front. Rain is mainly expected behind the frontal passage due to overrunning but with good elevated instability in place we could still see some thunderstorm activity which could produce small hail. Overall rain amounts don't appear too impressive with LREF guidance showing about a 25 percent chance for a half inch of rain across the area through Saturday night.

LONG TERM

(Saturday night through Thursday) Issued at 1218 AM CDT Fri Apr 17 2026

Rain chances continue Saturday night but begin to shift south as surface high pressure briefly moves over the area Sunday morning before moving east Sunday afternoon. This will leave low to medium rain chances primarily in the southern and western-most portions of the area Sunday during the day, with mainly cool and cloudy conditions in store. Breezy north to east wind continues into Sunday morning before easing Sunday afternoon and evening. Though mid-level ridging builds over the area Sunday, a disturbance within the southwesterly flow will likely generate showers and thunderstorms west of the area Sunday night which will shift east across our area into Tuesday. The cloudy and cooler conditions continue during this time, though wind will be lighter than the weekend.

We'll start to see the return of southeasterly flow Tuesday which looks to continue for the rest of the long term period. This will bring a day by day warming trend back to the area with highs returning into the 80s mid-week. Weak mid-level ridging remains over the area mid to late week keeping precipitation chances low, but disturbances aloft and a dryline in West Texas keep rain chances non- zero.

AVIATION

(12Z TAFS) Issued at 543 AM CDT Fri Apr 17 2026

Ceilings not quite as low as we previously thought, but lower clouds are in the vicinity. We will keep a tempo group in the San Antonio airports TAFs for lower ceilings for the next couple of hours. DRT is still VFR. Low clouds should spread over the airfield soon. All terminals will rebound to VFR by early this afternoon. Winds will be gusty this afternoon with gusts up to 25 kts likely. Low clouds will reform later tonight. A cold front will bring northerly winds around this time Saturday.
