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.
General Discussion:
Near-normal to above-normal temperatures are forecast to continue into the second half of the week, but, overall, will trend lower as rain chances increase by Thursday and Friday.
A few light showers have already been noted near the Houston metro and along the Gulf Coast early Wednesday. Any additional activity today will remain spotty in nature, with the best odds across the Central, Southern, and Coastal zones. A few isolated showers and thunderstorms can't be ruled out across Far West Texas as well, but coverage should be relatively low.
Higher rain chances will then take shape for Thursday and Friday as tropical moisture from the Eastern Pacific filters into Texas. Numerous showers and thunderstorms are forecast to develop across the western half of the state by Thursday afternoon before gradually expanding eastward to include portions of Central and North Texas, in particular, on Friday. Lingering rain can't be ruled out across Central, North, and East Texas on Saturday, before a drier outlook takes shape by Sunday. A sharp gradient in rainfall totals is likely from one side of the state to the other, with totals up to 0.25" east of I-35 transitioning to 2"-4" inches west of I-35.
Additional rain opportunities are likely by Monday and Tuesday as a cold front moves into the state. While exact timing and coverage will need to be fine-tuned in the days ahead, the highest rain chances with this round look to fall across North, Central, and East Texas through the first half of next week.
For temperatures, expect lows in the 50s and 60s and highs in the 70s and 80s to continue in the coming days. A cooler potential exists where rain chances materialize, but this will ultimately depend on coverage and timing. Regardless, the coolest systemwide day of the week is currently forecast to occur on Friday when the coverage of rain is highest. Temperatures will warm some over the weekend and into Monday, before the next cold front knocks temperatures back down to near-normal for the second half of next week.
Today:
Partly to mostly cloudy skies. Spotty showers will be possible across the Central, Southern, and Coastal zones. Highs in the 70s and 80s. Slightly warmer across the Rio Grande Valley.
Tomorrow:
Increasing cloud cover. Spotty morning rain across the South Central, Southern, and Western zones will lead in widespread showers and thunderstorms across the western half of the state by Thursday afternoon. Coverage continues to increase Thursday night. Instances of flash flooding can't be ruled out across West Texas. Lows in the 60s followed by highs in the 70s and 80s.
