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:
Near-normal to below-normal temperatures are expected again Tuesday afternoon as chances for scattered rain continue for parts of the state. These rain chances are generally favored west of I-35 and across Southeast Texas this afternoon, before a drier and warmer pattern takes shape for Wednesday and Thursday. High temperatures in the mid-to-upper 90s return to the forecast by the second half of the work week, with upper-level high pressure gradually settling in by the weekend. Another round of scattered thunderstorms can't be ruled out across East Texas on Friday and Saturday, but rain chances otherwise look minimal as the heat builds into the last full week of July. 

Today:
Becoming mostly sunny to partly cloudy. Showers and thunderstorms are expected across portions of the Hill Country and Southeast Texas. Highs in the 90s.

Tomorrow:
Morning clouds, then mostly sunny to sunny skies. Most stay dry, but a few isolated showers will be possible across Far West Texas in the afternoon. Lows in the 70s followed by highs in the 90s.
