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:
Continued quite warm conditions across Texas into Friday before a strong cold front moves through. Temperatures will trend much colder next weekend into early the following week; however, there is no sign of anything significantly colder than what was experienced last month. Rain chances return between late-Wednesday and Saturday, but not everyone will benefit.

Today:
A few areas of clouds, otherwise another very warm day is in store across the state. Highs will be in the 70s and 80s, with some areas near 90 in the Rio Grande Valley. A bit cooler tonight over most of the state, with a weak front moving through.

Tomorrow:
More cloud cover over Texas on Wednesday but still warm. Highs again will be in the 70s and 80s across the state, with some areas near 90 in the Rio Grande Valley. Warmer tomorrow night.
