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:
Colder temperatures have enveloped all of Texas, with widespread below-normal temperatures in place through Friday morning. Tomorrow morning will be the coldest for the ERCOT System this week. Temperatures will trend a bit warmer for Halloween before another cold front brings both rain chances and cooler temperatures on Saturday. Temperatures will trend warmer again heading into the start of next week, but only to about-normal levels on average. Looks like the warming trend may continue all of next week, with 80-degree highs possibly returning late in the week.

Today:
Feels like fall outside for a change. A chilly north wind will keep temperatures this afternoon mostly in the 60s, with 70s limited to South Texas. Winds will diminish tonight, leading to colder temperatures to start the day tomorrow. 30s in West Texas, 40s in the large metros and surrounding regions, low 50s in the Rio Grande Valley.

Tomorrow:
After a relatively cold start to the day, sunshine and less windy conditions will lead to a bit warmer afternoon tomorrow. Highs will generally be in the 60s in the northern half of the state and in the 70s in the southern half tomorrow afternoon.
