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:
Very warm, humid, and dry today ahead of a much stormier weather pattern. Round one will begin tomorrow, with thunderstorms expected across much of West and North Texas. On Thursday, the area of rain and thunderstorms will move eastward across the state. Some lingering showers and thunderstorms are likely Friday into Saturday, with rain chances for the South Central, Coast, and South zones. Rain and thunderstorms will ramp up significantly on Sunday, initially over West Texas, spreading eastward into early next week. Over the next 7-8 days, most of the state should record multiple inches of rainfall; however, much of South Texas won't be as fortunate. Temperatures will remain above normal through Friday, with some cooler air expected this weekend into early next week. 

Today:
Mix of clouds and sunshine across the state. Highs will be in the 80s across most of Texas. South Texas will see some low 90s. Warm and humid again overnight tonight.

Tomorrow:
Some widely scattered showers are possible tomorrow morning into mid-afternoon over Southeast Texas, as well as the Coast, South Central, and South zones. This activity will be generally light and insignificant. Attention will flip to the West zone tomorrow late-afternoon/early-evening as storms begin to ramp up. Activity will increase in coverage and intensity tomorrow night over West Texas, east into the Hill Country, and expanding across North Texas as well. Some marginally severe storms are possible, with large hail the primary threat. Temperatures tomorrow will continue to run well above normal; however, West Texas will see a significant decline in temperatures with rain and clouds increasing tomorrow afternoon. Less of a change cooler over the rest of the state due to fewer precipitation chances during the daytime hours.
