From Rusty Garrett:
A weak cold front is due to pass through Central Texas overnight into Friday morning. While that front will help to knock our temperatures down, afternoon highs will still remain quite a bit above average.
As the front creeps through the area overnight, temperatures drop into the lower and middle 40s with mostly clear skies.
Afternoon highs begin a brief cooling trend Friday, dropping down into the lower and middle 70s. By Saturday and Sunday, highs will only reach the middle and upper 60s.
Another weak disturbance approaches the area Sunday afternoon, possibly sparking a few isolated showers or stray rumbles of thunder as it moves through. Rain chances remain low during the late afternoon and evening hours Valentine's Day. A few showers may linger until early Monday morning, however another warming trend begins Monday through the middle of next week.
