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:
Above-normal temperatures and below-normal rainfall (for most of the state) will continue through the remainder of this week and likely through at least Friday of next week. A change in the weather pattern is possible the weekend of October 18-19, but far from a guarantee as of now. For temperatures, this means highs mostly in the low to mid-90s for the eastern half of the state, including all the large cities. West Texas will see highs ranging from the mid-80s to low 90s. Rain chances will be limited to South Texas over the next few days, and to Far West Texas today and again Sunday and into early next week. Most of Texas will continue to see a dry weather pattern for the foreseeable future.

Today:
A few thunderstorms are seen over the Panhandle this morning but will dissipate by afternoon. There are also a few showers over the Rio Grande Valley this morning, with continued rain chances throughout the day today. Some isolated showers and storms will develop this afternoon over a larger portion of South Texas, likely south of San Antonio – as well as some showers over southern West Texas this afternoon. Otherwise, most of the state will see another dry day today. Temperatures will mostly be within a degree or two of yesterday, with a slight overall trend cooler from yesterday (though some locations will not be any cooler than yesterday). 80s for highs over West Texas and low to mid-90s for the rest of the state.

Tomorrow:
Trending drier but also less humid. Rain chances on Thursday will be limited to South Texas, mostly again in the Rio Grande Valley – as well as a few showers again in southern West Texas. Temperatures will again be similar to today, with the eastern half of the state a degree or two cooler, while trending slightly warmer over West Texas.
