KEY MESSAGES

- Isolated to widely scattered showers and storms over the Hill Country late afternoon and early evening if cap breaks.

- Active and unsettled weather pattern to return Tuesday afternoon through Wednesday afternoon with localized flooding issues possible. - Rounds of showers and storms are forecast for next weekend

SHORT TERM

(Tonight through Monday night) Issued at 126 PM CDT Sun May 24 2026

Sunny skies are likely to remain across portions of the Southern Edwards Plateau, Hill Country, and I-35 corridor at least through mid afternoon. The scattered cloud cover across the rest of the local area could remain throughout this afternoon. As the afternoon progresses, day time heating will help today's highs to reach the upper 80s over most locations and even into the lower 90s across the Rio Grande. It looks like most areas to remain quiet for the rest of this afternoon into the evening period, however, isolated to widely scattered thunderstorm activity could occur over parts of the Southern Edwards Plateau, Hill Country, and I-35 corridor. If the cap continues to weaken and breaks, there is plenty of moisture and conditional instability for a few storms to become strong to marginally severe. Main hazard likely to be strong to damaging wind gusts. In addition to that, locally heavy rain is possible over these areas and can't rule out a quick one to two inches of rainfall in a couple of hours as storm motion is relatively weak.

Looking into Monday, the weather forecast calls for dry conditions for most areas with a few storms anticipated across portions of the Hill Country and I-35 corridor including the Austin metro area mid to late afternoon into the early evening. At this time, no severe weather is anticipated with these storms if they manage to develop. Monday's highs are forecast to range from the mid to upper 80s across most of South Central Texas and lower 90s along the Rio Grande Plains.

LONG TERM

(Tuesday through next Sunday) Issued at 126 PM CDT Sun May 24 2026

By Tuesday afternoon into the evening, an upper level short wave is forecast to push across west Texas and over the Hill Country. At lower levels, a moist southerly flow is forecast to be in place ahead of a dryline likely to be located over the Pecos area. The initial convection across northeast Mexico has the potential for storms to become strong to severe and then moves into the Rio Grande Plains. As the line of storms pushes across the Rio Grande and parts of the Southern Edwards Plateau, the severe weather hazards anticipated are large to very large hail and damaging wind gusts. Can't rule out an isolated tornado. In addition, locally heavy rain is possible with pwats running from 1.5 inches to 2.0 inches areawide. Therefore, a concern for flooding is growing for some parts of the local area as 1 to 3 inches of rainfall are possible from Tuesday evening into Wednesday afternoon. Can't rule out localized 5 inches of rainfall for that period.

Drier conditions arrive across the Rio Grande Plains on Wednesday night and then moves eastward into Thursday. There are chances for showers and storms mainly along and east of I-35 corridor on Thursday afternoon but the dry weather trend expands for all of South Central Texas for most of the day on Friday. Rain chances return Friday night into the weekend as several upper level short waves move across central Texas.

AVIATION

(18Z TAFS) Issued at 1153 AM CDT Sun May 24 2026

Much better flying conditions expected today with all I-35 TAF sites remaining in VFR throughout the period. Light winds expected from northeasterly to VRB at times before switching easterly overnight and into tomorrow. There is a possibility for isolated convection to form late this afternoon into this evening however confidence isnt high enough to add at this time. For KDRT MVFR CIGs currently should give way to VFR as this cloud deck eventually erodes by this afternoon. Winds should be light and southeasterly to easterly throughout the period with VFR CIGs continuing.
