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:
Frequent fronts will continue to support a very changeable weather pattern across the ERCOT Region. Trending generally warmer this afternoon through Friday, with a weak mid-week front resulting in a bit cooler temperatures Wednesday night/Thursday morning. Otherwise, lots of 60s and 70s for highs ahead this week (80s in South Texas). The weekend continues to provide a lot of uncertainty, with the computer models struggling with timing and intensity of the next shot of colder air. Currently, Saturday still looks mild before trending colder Sunday and Monday. No precipitation in Texas (as well as limited cloud cover) through at least Thursday. Rain chances increase over the eastern half of the state this weekend, though it looks limited in scope. 

Today:
Chilly this morning with mostly clear skies across Texas. Temperatures will trend warmer this afternoon, with highs in the 60s and 70s. Not as cold tonight, with most of the state not expected to drop below 40. 

Tomorrow:
A weak cold front will move through tomorrow but there won't be much noticable difference. Highs tomorrow will again be mostly in the 60s and 70s, with West Texas a bit cooler than the day prior, and the rest of the state mostly warmer. No rain with this front, but temperatures will be a bit cooler Wednesday night into Thursday morning.
