Weather Forecast Details


General Discussion:
The temperatures in Texas will be riding a roller coaster over the next seven days. Record-breaking highs today will be followed by the coldest morning thus far this season to start next week, before trending back into the 80s for the second half of the week.

Today:
Mostly sunny and very warm this afternoon. Record highs likely in numerous locations. Highs will range from 75-80 over West Texas and 90-95 across South Texas and parts of Central Texas.

This Weekend:
Another very warm day on Saturday to start the weekend. Highs will be mostly in the 80s, with 90s found in South Texas. A strong cold front will move through the state between Saturday afternoon and Sunday morning. A few isolated showers are possible near the front and along the coast late-Saturday into early-Sunday. The big news will come with the sharply colder temperatures. Sunday afternoon’s temperatures will only be in the 50s across North and West Texas, 60s in Central Texas, with warmer 70s and 80s in South Texas. A blustery north wind will accompany the colder temperatures into Sunday night. Lows Sunday night will be in the mid-20s to low 30s in West Texas, 30s in the large cities, and 40s into South Texas.
