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 fairly steady weather pattern continues into the start of the work week as high temperatures once again climb into the 90s Monday afternoon. A few isolated pop-up showers and thunderstorms can't completely be ruled out (especially across the Rio Grande Valley), but most areas will stay dry with more of the same expected again Tuesday. A weak cold front will then approach Far North Texas on Wednesday, likely sparking up scattered rain and thunderstorms across the Panhandle. As the front eventually stalls across Northwest Texas, system-wide temperatures will attempt to drop by a few degrees for the second half of the week, but highs likely remain in the 90s for the major cities. Isolated to scattered rain chances look to continue across Northwest Texas during this timeframe, with highest totals currently favored across Far North Texas and along the Coast over the next seven days.

Today:
Mostly sunny to partly cloudy skies. A few isolated showers and thunderstorms will be possible, especially across Far South Texas and the Rio Grande Valley. Highs in the 90s.

Tomorrow:
Mostly sunny to partly cloudy skies. A few isolated showers and thunderstorms will be possible, especially across Far South Texas and the Rio Grande Valley. Lows in the 60s and 70s followed by highs in the 90s.
