Weather Forecast

The ERCOT Weather Forecast is developed by ERCOT Meteorologists Chris Coleman, Mia Montgomery, Brandon Gale, and Christi Eastham. The interactive map displays today’s temperature information for major cities located within the ERCOT grid. Hover over a city to see the most recent temperature forecast. 


Note: A Weather Zone is a geographic region designated by ERCOT in which climatological characteristics are similar for all areas within such region. This map displays the various Weather Zones that exist within the ERCOT footprint, but it does not necessarily include all counties that have participation within the ERCOT market.

Weather Forecast Details


General Discussion:
Cold air is departing Texas and will be quickly replaced by a return to above-normal temperatures. 80s and 90s for highs most days from the second half of this week through at least Thursday of next week. Peak temperatures will be between Friday and Sunday, with the hottest temperatures expected over North Texas and especially West Texas. There may be a 100-degree high in northern West Texas later this week, with Saturday having the hottest potential. No chance of rain until late next week at best. 

Today:
More sunshine than clouds across the state today. Warmer this afternoon. Highs generally in the 70s over the eastern half of the state and 80s over the western half. 80s also in the Rio Grande Valley this afternoon. Not as cool tonight.   

Tomorrow:
Mostly sunny and very warm on Friday. 80s over the eastern half of Texas; 90s over West Texas. Mostly 50s for lows Friday night into Saturday morning. Trending even hotter into the weekend.
