Weather Forecast

The ERCOT Weather Forecast is developed by ERCOT Meteorologists Chris Coleman, 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:
Cold temperatures remain today with a warming trend expected through the weekend and into early next week. Some cloud cover and precipitation chances across mainly Southeast Texas will initially make this warming slow to occur, and temperatures will likely remain below-normal across this region through Sunday. Near-normal to slightly above-normal temperatures are then expected Monday through Wednesday next week before a weak cold front brings slightly cooler temperatures for Thursday.

Today:
Mostly cloudy across South and East Texas with light rain/drizzle possible. In the Hill Country and near the Austin and San Antonio metros, light freezing rain/drizzle will be possible at times, especially overnight tonight. Partly to mostly sunny and dry across the remainder of the state. Highs in the 30s and 40s.

This Weekend:
Mostly cloudy across South and East Texas with chances for showers and thunderstorms; partly to mostly sunny and dry across the remainder of the state. Below-normal temperatures prevail statewide through Saturday before warming closer to normal on Sunday, especially across West Texas.
