Weather Forecast Details


General Discussion:
Above-normal temperatures will continue through Friday, ahead of a strong cold front that will bring much cooler temperatures to the state from this weekend through early next week. Highs in the upper 80s to low 90s today will trend to 60s and 70s by Sunday and Monday, while lows will fall from the upper 60s and low 70s tonight into the 40s and 50s by early next week. Temperatures will then gradually warm during the second half of next week, but are unlikely to reach this week's levels. Shower and thunderstorm chances will continue to impact parts of ERCOT today and again on the weekend, with more rain and storm chances likely next week. 

Today:
Thunderstorms that developed over West Texas last night have mostly weakened, though some lingering light precipitation is possible between Dallas-Fort Worth and Austin through the morning hours. Skies will clear through the day ahead of another round of storm development over West Texas this afternoon and evening. Some of these storms may again be severe. Temperatures this afternoon will be similar to yesterday or slightly warmer in some areas, expect mid- to upper 80s across North and Central Texas, climbing to near or above 90 across South Texas, the Rio Grande Valley, and the Lubbock area. Warm and muggy again tonight, with lows in the upper 60s to mid-70s for most of the state. 

Tomorrow:
Thunderstorms from today's West Texas activity will push eastward overnight but should weaken considerably before reaching I-35 locations. Some slight storm chances remain east toward the I-35 corridor during the afternoon. Above-normal warmth continues, with another round of 80s expected across much of the state and 90s still possible in South Texas and the High Plains. This will be the last day of well above-normal temperatures before the cold front arrives Friday night into Saturday.
