North and Central Texas step into Wednesday under another blanket of warmth and humidity — a familiar pattern this fall, but one that won’t last much longer. Afternoon highs will climb into the 90s, and when you factor in the moisture-rich air, heat index values will hover near 100 degrees. A few isolated showers and thunderstorms may pop up, especially across East and Central Texas, but most communities will remain dry.
The bigger change arrives Thursday.
Moisture increases ahead of an approaching cold front, helping scattered showers and thunderstorms develop across western North Texas. By Thursday evening and into the night, the front pushes southward through the region, setting the stage for a dramatic shift in the weather.
Friday will feel like a different season entirely. Much cooler air settles in, dropping afternoon highs into the 60s and 70s. Winds will surge behind the front, sustained at 20–30 mph with gusts reaching 40 mph — strong enough to turn everyday outdoor items into airborne hazards. Residents are urged to secure lawn furniture, trash bins, decorations, and anything else that could be lifted by the wind.
The cooler, drier air sticks around through the weekend. Expect crisp mornings in the mid‑40s and 50s, with afternoons topping out in the 60s and 70s. By Monday, temperatures begin a gradual rebound into the upper 70s and 80s.
Austin & San Antonio Region
The day begins hot and humid, with heat index values pushing up to 105 degrees from the I‑35 corridor into the Coastal and Rio Grande Plains. Breezy south‑southeast winds — gusting up to 25 mph — will accompany isolated to scattered afternoon showers and storms, mainly east of I‑35.
Tonight stays warm and muggy as clouds thicken. Most areas will hold in the low to upper 70s, with light to moderate southeast winds across the southern Edwards Plateau and western Hill Country.
A more serious concern develops overnight: heavy rain and localized flooding across parts of the Southern Edwards Plateau, especially Val Verde County. Several rounds of showers and storms may move through, prompting a level 2 of 4 risk for excessive rainfall. Residents should have multiple ways to receive weather warnings.
By predawn Friday, the cold front arrives. Expect a few light showers along the boundary, followed by a sharp wind shift to the north with gusts up to 35 mph. Temperatures fall quickly, ushering in a cooler stretch through the weekend with highs in the 60s and 70s and lows dipping into the 40s and 50s.
Thursday will still be warm — highs in the 80s and 90s — but once the front passes, the region settles into a refreshing autumn pattern. Heavier rains remain possible tonight into early Friday across the Southern Edwards Plateau, and additional rain chances may return by mid‑week next week.
