Weather Forecast Details


General Discussion:
Very limited warmth this week, though temperatures will trend less cold into Thursday, which will likely be the warmest day this week for the ERCOT System. Another cold front is due to move through Texas between Thursday and Friday. This could lead to another cold weekend, but, at this time, it's not looking as cold as last weekend. Precipitation chances will also be limited this week, with most of the state remaining dry. South and Coast zones will have the best rain chance in the Thursday-Friday time frame.

Today:
Mostly sunny skies across the state today but still quite chilly. Most locations will top out in the 20s and 30s this afternoon, with 40s limited to South Texas. Cold again tonight, but most locations will not be as cold as last night. Clouds will be on the increase from the west, and could impact I-35 locations warmer if the clouds arrive earlier than anticipated.

Tomorrow:
Significantly warmer Tuesday afternoon, with 30s and 40s for highs common and 50s in South Texas. Not as cold tomorrow night, but the majority of the state will see another freeze.
