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:
Mostly mild-to-warm temperatures across the ERCOT Region into Saturday before a strong cold front knocks temperatures much colder Sunday and Monday. The intensity of the cold air is still being determined, but it could approach the coldest nighttime/morning lows Texas has seen thus far this season. Temperatures will rebound warmer on Tuesday and are likely to continue to be on the warm side through the remainder of next week (and possibly the following week). Precipitation will continue to be limited, with most falling over the eastern half of the state between Saturday and next Tuesday (looks to be all rain).

Today:
A weak cold front is moving through the state today. This will result in lower humidity and a bit colder temperatures tonight. However, daytime temperatures will be impacted minimally.

Tomorrow:
Another chilly start (though above freezing throughout the ERCOT territory). Mostly sunny skies will push temperatures tomorrow afternoon into the mid-60s to mid-70s. Not as cold tomorrow night.
