Weather Forecast Details


General Discussion:
Today is the final day of the significant rain event that has impacted much of the state over the past few days. The ERCOT Region will continue to see shower and thunderstorm chances for parts of the state most days for the foreseeable future, but this activity will be much more scattered, will rely more on daytime heating to develop late in the day, and will also include higher severe potential. North Texas will be most favored for storm chances from late this week through early next week. Temperatures will also be trending significantly warmer. 80s and 90s for highs will become increasingly common heading toward Friday and continuing this weekend through early next week. Overnight temperatures and morning lows will be commonly in the 60s and 70s with the higher humidity assisting. Next Monday is a day to keep an eye on as models suggest this may be the hottest day for the ERCOT System over the next 7 days. 

Today:
Scattered to numerous showers and thunderstorms will be focused over Southeast Texas today, especially in the Coastal Plains. Houston has a good chance of additional rain today. The other three large metros all have rain/thunderstorm chances, but it will be much more scattered than recent days. Dry across West and South Texas today. Temperatures this afternoon will be warmer than yesterday. Mostly 70s this afternoon over the eastern half of the state and 80s over West and South Texas. Lows tonight mostly in the 60s. 

Tomorrow:
Noticeably drier on Thursday. There could be a few isolated showers/thunderstorms pop up late in day in the West and South Central zones, but that’s about it. Widespread 80s tomorrow afternoon with some low-90s in Far West Texas and the Rio Grande Valley.
