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:
The work week will end on another hot note as highs climb into the 90s and low 100s Friday afternoon. Cooler temperatures may be found near Houston and along the Coastal zone as scattered showers and thunderstorms attempt to develop throughout the morning and into the early afternoon. A few showers or thunderstorms can't be ruled out across portions of Central, North, and Far West Texas as well, but coverage looks fairly isolated.

Above-normal temperatures will continue in the days ahead, with system temperatures likely building by a degree or two into the upcoming weekend. Rain chances will come down, minus some lingering opportunities along the Coast. Expect 90s and low 100s to still be a common theme across the state through much, if not all, of next week.

While far from a guarantee at this point, long-range forecast guidance continues to hint at a pattern change for at least parts of the ERCOT Region around the 19th or 20th of September. We'll need to watch how trends unfold in the days ahead for the possibility of at least slightly lower systemwide temperatures and better rain chances into the last third of the month.

Today:
Mostly sunny to partly cloudy skies. Slightly cloudier and cooler along the Coastal zone where scattered showers and thunderstorms are possible. Rain chances become more isolated for portions of Central, North, and Far West Texas. Highs in the 90s and 100s.

Tomorrow:
Mostly sunny to partly cloudy skies. Isolated rain chances for parts of the Coastal, Eastern, and Far Western zones. Lows in the 70s and 80s followed by highs in the 90s and 100s.
