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:
Another very hot week ahead. Widespread, prolonged periods of triple-digit highs are not common in September, and this week’s temperatures will track 10 to 15 degrees above normal. Some new records are likely. There will still be some scattered rain chances this week, but most locations will see little to no precipitation. Wednesday and Thursday will bring the best rain opportunities to the largest area, but as conditions trend drier heading into the weekend, hotter temperatures will take hold. Saturday currently looks to be the hottest day across the ERCOT system. This heat will extend into next week, but a cold front is possible late next week.
Today:
Mostly sunny and hot today. Highs this afternoon will generally be within a degree of yesterday, ranging from the mid-90s to around 105 across the state. A few scattered showers and thunderstorms will develop this afternoon, mostly over the East and Coast zones. There is a slight chance that a stray cell or two makes it into eastern portions of the South Central zone late in the day toward evening.
Tomorrow:
Rain chances and areas of potential impact increase on Wednesday. As a result, temperatures will likely be slightly less hot tomorrow. Scattered showers and thunderstorms will increase tomorrow afternoon, especially over the Hill Country and Panhandle. The Coast, South Central, and northern two-thirds of the West and the Far West zones will also see a few showers and thunderstorms. Most of this activity will dissipate with sunset.
