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:
Much drier conditions ahead over the next seven days. May see a band of showers/thunderstorms moving along a front across East Texas on Sunday, but that’s about it for the foreseeable future. Otherwise, attention turns to temperatures behind Sunday’s strong cold front. Monday and Tuesday will be significantly colder than this morning. Widespread hard freezes are expected across West Texas and at least parts of North Texas Monday morning. The rest of the state will be colder on Tuesday morning, with freezes possibly expanding southward into parts of Central Texas. Temperatures will rebound warmer for the second half of next week, with 80s likely to return. 

Today:
Mostly sunny skies and cooler. Highs this afternoon will be slightly below normal, with most ERCOT locations topping out between the mid-60s and mid-70s. Chilly again tonight, with lows mostly in the 40s.

Tomorrow:
Mostly sunny and warmer Friday afternoon. Highs will range from the mid-70s to mid-80s, with parts of West Texas and the Rio Grande Valley the warmest. Not as cool tomorrow night.
