Weather Forecast

The ERCOT Weather Forecast is developed by ERCOT Meteorologists Chris Coleman, Mia Schroller, and Brandon Gale. 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:
A similar day-over-day temperature trend continues this week with highs in the mid- and upper 90s. Afternoon heat indices in the upper 90s and low 100s can be expected daily. Rain chances will generally be confined to Far West Texas and the Panhandle in the days ahead, along with a few isolated showers along the Gulf Coast.

Temperatures look to gradually build into the holiday weekend as upper-level high pressure expands westward, with upper 90s and low 100s forecast. A few additional rain chances may be possible in parts of North and Central Texas early next week, but temperatures will otherwise remain warm for much of the state through the foreseeable future.

Today:
Mostly sunny to partly cloudy skies. Scattered rain is expected to develop across parts of Far West Texas and the Panhandle, along with a few isolated showers across the Coastal zone. Highs in the 90s with afternoon heat indices in the upper 90s and low 100s.

Tomorrow:
Mostly sunny to partly cloudy skies. Isolated-to-scattered rain is possible across parts of Far West Texas and the Panhandle, along with a few isolated showers across the Coastal zone. Lows in the 70s followed by highs in the 90s. Afternoon heat indices in the upper 90s and low 100s.
