KEY MESSAGES

- Persistent dry conditions with slightly above normal temperatures.

- Elevated heat index values late week into the weekend, especially along and east of I-35 and across most of the Rio Grande plains.

SHORT TERM

(Today through Thursday) Issued at 1220 AM CDT Wed Jun 24 2026

Summer is here and it sure feels like it. South Central Texas remains under mid-level ridging with persistent south to southeasterly low level flow. Southerly wind will be lightest this morning then become breezy through this evening with gusts up to 20- 25 mph. While temperatures will be hot in the low to upper 90s, dewpoints mix into the 60s for most of the area this afternoon bringing lower heat index values than previous days topping out at about 101 degrees. Clouds build over the area again tonight keeping lows in the 70s before scattering late morning and afternoon. Wind may be slightly more gusty on Thursday, but otherwise high temperatures and heat index values will be similar to those seen today. No rain is forecast.

LONG TERM

(Thursday night through Tuesday) Issued at 1220 AM CDT Wed Jun 24 2026

The subtropical ridge remains over the region into the weekend, shifting further east early next week though South Central Texas will still remain under its influence. Dry conditions with daily high temperatures in the 90s are expected to persist under this pattern. Decent mixing each afternoon will help keep heat indices below Heat Advisory criteria, though values will likely be in the triple digits for many each afternoon keeping minor to moderate heat risk over the area. Breezy wind each afternoon and evening subsides slightly overnight.

AVIATION

(12Z TAFS) Issued at 542 AM CDT Wed Jun 24 2026

A stormy pattern continues over the Panhandle and OK, while the upper ridge remains dominant over Central TX. The resulting pressure gradient at the surface will likely support more daytime gusts to 25 knots in the midday to early evening hours. The dry pattern and daytime breeziness will continue to slowly erode the gulf moisture and residual soil and vegetation moisture over time. MOS guidance has been keeping DRT out of low CIGs the past couple days, an unlike yesterday, the Nighttime Microphysics imagery looks to agree with that projection. Austin will also show a short residence time of low clouds possibly primarily scattered clouds with not much ceiling as the morning/daytime wind directions veer slightly to the SSW at times. The SAT/SSF cloud restrictions should last the longest, but the time windows were trimmed to starting after midnight and ending before noon.
