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:
A couple of cold fronts are on tap this week; however, neither front is expected to be as strong as this past weekend’s front – with a quick return to very warm temperatures to follow. In other words, the above-normal temperature pattern will continue for another week. There are increasing chances for a stronger front in the middle of next week. Tomorrow’s front will bring only isolated-to-scattered showers to parts of East Texas. A more promising period of rain should impact ERCOT beginning on Thursday across North and West Texas, then expanding southeastward on Friday, with some strong to severe thunderstorms possible. This area of precipitation may expand farther south than this past weekend. Additional rain chances are possible into Saturday over East Texas.

Today:
Dry, with increasing heat and humidity as the day progresses. Most of Texas will top out in the low to mid-90s this afternoon, with some hotter temperatures in South Texas.

Tomorrow:
A weak front will result in temperatures coming in 10-15 degrees cooler over North and West Texas on Tuesday; however, the front will lose steam beyond that, with much less cooling over the rest of the state. Some isolated showers are likely over East Texas tomorrow afternoon, dropping south with the front. Scattered showers and maybe a thunderstorm are possible in the Houston metro late in the day, toward evening.
