KEY MESSAGES

Updated at 1211 PM CDT Sun Jul 26 2026

- Hot and dry weather is expected through the end of July.

- Rising temperatures this week may lead to increasing heat risks.

SHORT TERM

(Today through Monday) Issued at 1231 AM CDT Sun Jul 26 2026

Sunday brings another hot and dry day with highs straddling seasonal normals in the mid 90s to around 100. A minor rise in Gulf moisture arriving with a subtle inverted trough will boost peak heat indices southeast of the Balcones Escarpment and across the Coastal Plains into the 100 to 107 range. The added moisture may bring a lone shower or two over the Coastal Plains this afternoon. Otherwise, expect the usual scattered and benign cumulus dotting a sunny day. Monday offers similar weather. The afternoon wind direction is expected to be slightly more southerly and help raise air temperatures a notch, but dew points should be slightly lower, leading to more or less the same hot weather.

LONG TERM

(Monday night through Saturday) Issued at 1231 AM CDT Sun Jul 26 2026

The dog days of summer continue through the end of July. The core of strong subtropical ridging will wander around the Texas Panhandle and New Mexico through the week. As conditions remain dry and the airmass warms, near surface humidity should mix out more and allow daytime highs to inch upwards into the triple digits. Outside of the slightly cooler higher elevations in the Hill Country, most of South Central Texas is forecast to see multiple days of 100F+ highs this week. Overnight lows will stay around the mid to upper 70s. This combination may lead to rising heat risks through the week.

The forecast through at least Friday stays dry for essentially everyone in the local area. However, there is good model agreement that the core of the subtropical ridge will slowly saunter a little more west this upcoming weekend. Northerly flow through the Plains and increased troughiness could support some low end rain chances during the weekend, though the moisture supply does not look especially plentiful at this time.

AVIATION

(18Z TAFS) Issued at 1211 PM CDT Sun Jul 26 2026

VFR conditions under mostly clear skies are expected to prevail through the period. MVFR ceilings appear less likely tonight with HREF guidance indicating only a 30 percent chance for redevelopment over the I-35 corridor. While the low levels should be slightly drier than previous nights, there still could be enough moisture for some clouds by Monday morning and opted to include a SCT deck at AUS/SAT/SSF. DRT remains VFR.
