From Rusty Garrett:
Clouds linger for the beginning of the night, but should move out after midnight. After clouds exit, temperatures plummet into the lower and middle 20s by Friday morning with wind chill values in the upper teens. Highs Friday return into the lower and middle 40s with mostly clear skies.
Temperatures return close to freezing Friday night but will likely increase by Saturday morning as warm air moves back into Central Texas. Highs Saturday climb into the upper 40s and lower 50s. Our next cold front arrives Sunday bringing with it a low chance of showers near and east of I-35 Sunday. Temperatures won't be impacted too much by Sunday's front, only dropping a few degrees into the lower and middle 60s.
Long range model data shows another strong blast of Arctic air moves into the United States for the middle of next week. The brunt of the next Arctic air intrusion seems to be focused toward the Great Lakes, east coast, and Tennessee River Valley, however recent model data suggests some Arctic air may make it into Texas. As of now, temperatures look to drop into the middle and upper 40s behind the front Wednesday afternoon, but confidence is low in regards to when next week's front moves in and how cold it'll be behind it.
