Weather Forecast Details


General Discussion:
Friday will feature near-normal to above-normal temperatures as highs climb into the mid-90s and upper 90s. Isolated showers have already been noted near and south of the San Antonio area Friday morning, with additional activity likely across the Southern zone this afternoon.

Similar system temperatures are expected into Saturday, with scattered rain chances generally confined to Far West and Northwest Texas. The heat will likely build by a degree or two into Sunday, before a pattern change starts to take shape for parts of the state early next week.

A weak cold front is still expected to move into North Texas by Monday and Tuesday, bringing lower temperatures to the Far Northern and Western zones as better rain chances develop. Expect highs to fall into the 80s for Lubbock and into the low 90s for Dallas, while near-normal to above-normal temperatures prevail for Houston, Austin, and San Antonio. The highest rain chances during this timeframe will fall across West Texas and the Panhandle, with daily opportunties likely continuing in these regions through much, if not all, of next week.

Today:
Mostly sunny skies across the majority of the state. Partly to mostly cloudy skies are forecast across South Central and South Texas, where isolated to scattered showers and thunderstorms are expected. Highs in the mid-90s and upper 90s.

This Weekend:
Increasing rain chances across Far West Texas and the Panhandle. Lows in the 70s and 80s followed by highs in the 90s and low 100s, with Sunday likely being a degree or two hotter than Saturday on a systemwide scale.
