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:
Above-normal temperatures will continue before a pattern change brings widespread rain chances and cooler temperatures to the ERCOT Region for the second half of the week.
Another relatively hot afternoon is expected Monday as high temperatures climb into the widespread 90s. A few showers have been noted near the Dallas area this morning, but rain chances will remain somewhat isolated for the remainder of the day. Similar temperatures are expected for most locations Tuesday, with the exceptions being Far West Texas and the Panhandle as scattered showers and thunderstorms develop throughout the day.
This will be the start of a multi-day rain event for the state as tropical moisture from Hurricane Polo near the Baja Peninsula syncs up with an approaching cold front. Widespread rain chances will gradually move across the ERCOT Region through the Wednesday-Friday timeframe, likely sparking flash flooding and even severe weather concerns at times. While coverage won't be as high by the weekend, lingering showers and thunderstorms will extend into Saturday and Sunday, especially across Central and South Texas. Rainfall totals upwards of 3"-6" will be possible for at least the eastern two-thirds of the state by this time next week, with localized higher totals possible.
The first notable temperature drop-off of the season will result from the front and rain-cooled air. Near-normal to below-normal temperatures are forecast to return by Thursday and Friday, with current forecasts calling for highs in the 70s and 80s for all but Far South Texas. This will likely continue through the first weekend of October, with long-range forecasts calling for more of the same into much of next week as well.
Today:
Mostly sunny to partly cloudy skies. A few showers near the Dallas area in particular, with rain chances remaining fairly isolated throughout the day. Highs in the widespread 90s.
Tomorrow:
Increasing rain chances across Far West Texas and the Panhandle as scattered to numerous showers and thunderstorms take shape. Cooler in these regions, with lows in the 70s followed by highs in the 80s. Otherwise, expect highs in the 90s for the rest of the state.
