Weather Forecast
The ERCOT Weather Forecast is developed by ERCOT Meteorologists Chris Coleman, Mark Witte, 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:
An Excessive Heat Warning is in effect for the Dallas metro today for a dangerous combination of high temperatures and humidity. Heat indices in the 110-112 degree range are possible in Dallas. Heat Advisories are in effect for much of state. These Heat Advisories and Warnings will likely be extended through the weekend as a dome of high pressure continues across North Texas and southern Oklahoma. Afternoon temperatures are forecast to be near the 100-degree mark for the major Texas cities within the ERCOT region through the Fourth of July holiday. Moreover, rain chances will be slim and mainly limited to isolated showers along the Gulf Coast. Otherwise, a weak tropical disturbance will come ashore well south of Brownsville along the Mexican coastline on Sunday bringing an influx of tropical moisture (showers) for the Lower Rio Grande Valley. Further east in the South-Central Atlantic, another tropical disturbance is showing a high chance of development in the coming days; however, the system is at least 9-10 days away from impacting the Texas Gulf Coast.
Today:
Partly to mostly sunny, hot, and humid with a chance of an isolated afternoon or evening shower or non-severe thunderstorm mainly near the Gulf Coast. Afternoon highs in the mid-90s to low 100s. A south-by-southeast wind of around 10 mph with higher gusts.
Saturday:
Partly to mostly sunny, hot, and humid with a chance of an isolated afternoon shower or non-severe thunderstorm. Morning lows near 80. Afternoon highs from the mid-90s to 100. A south-by-southeast wind of around 10 mph with higher gusts.
Sunday:
Partly to mostly sunny, hot, and humid with a chance of an isolated afternoon shower or non-severe thunderstorm. Morning lows near 80. Afternoon highs in the upper-90s. A south-by-southeast wind of around 5 to 10 mph with higher gusts.
