Arctic blast coming to San Antonio, icing possible in Texas Hill Country

SAN ANTONIO (KTSA News) — A winter blast is expected to move through the greater San Antonio area later this week.

The National Weather Service in New Braunfels said a strong, arctic cold front will move through the area Wednesday night with freezing temperatures.

The front will bring a few nights of hard freezes to the region as well as a chance for icing from freezing rain and sleet Thursday morning across parts of the area.

High temperatures will be around 70 degrees in San Antonio through Wednesday.  The cold front is expected to move through Wednesday night, dropping the low temperature to 34 degrees that night.  That will also be the warmest it will be all day Thursday.

With the front, there is a chance for freezing rain and sleet — leading to potential icing.  The greatest likelihood of these conditions is north of Bexar County in the Texas Hill Country.  This higher likelihood includes portions of Comal and Hays counties, as well as all of Kendall and Bandera counties.

Most of the Austin metro area will see a good chance of icing — with Thursday’s temperatures expected to stay below freezing all day there.

There is a chance for icing north of US 90 from Del Rio to Luling.

The rest of the week through Sunday will see temperatures gradually warm in San Antonio — from a high near 40 Friday to the mid-50s Sunday.  There will continue to be a freeze each night, with lows ranging from 22 degrees Friday night to 29 degrees Sunday night.

The weather service said this cold snap is not as severe as the region saw last February and that the forecast is expected to continue to evolve as we get closer to the end of the week.
