Weather Forecast
The ERCOT Weather Forecast is developed by ERCOT Meteorologists Chris Coleman, Mia Schroller, 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:
Shower and thunderstorm chances will continue through at least the next week; however, days with widespread impacts will be limited. Much of the state will be warm and dry for Memorial Day. Temperatures over the next 7 days will mostly top out in the 80s, but drier periods will produce some low to mid-90s in spots.
Today:
Much less active over the eastern half to two-thirds of the state today, with more sunshine as well. This will help push temperatures warmer today, with highs well into the 80s for most ERCOT locations. South Texas and southern West Texas will see some 90-degree highs this afternoon. Expect thunderstorms to develop over Far West Texas late this afternoon into evening. These storms will progress eastward overnight and should approach the I-35 locations well after midnight. The storms may hold together as they move into the Austin-to-San Antonio corridor in the early morning hours, but models are more aggressive with northern storms holding together that could impact DFW closer to daybreak.
Memorial Day Weekend:
Look for an increase in thunderstorm activity across the eastern half of the state during the daytime hours on Saturday. Storms could develop by late-morning/early-afternoon and continue into Saturday night. The South Central, South, and Coast zones are especially prone for thunderstorms on Saturday. Temperatures will also likely trend cooler tomorrow as a result. Additional thunderstorms will develop over Far West Texas late-afternoon Saturday into evening, progressing eastward overnight. The best bet for storms holding together late tonight will be across North Texas. Sunday will trend drier than Saturday, and temperatures will pop warmer again. Some of Saturday night’s storms may linger into Sunday morning over Southeast Texas. North and especially West Texas have the best opportunities for additional development during the day on Sunday. New storms could also develop in Southeast Texas, but again, less active in general across the state compared to Saturday. Memorial Day shows an even greater trend drier. The best storm chance on Monday will be within the East zone. Temperatures will be mostly in the 80s for highs Saturday and Sunday, with 90s becoming more common for Memorial Day.
