The possibility of an overnight snowstorm north of Brown County was posted Thursday by the National Weather Service, with accumulations of between 3 and 6 inches possible in the Interstate 20 corridor and northward.
Forecasters with the weather service in San Angelo issued a heavy snow warning for Callahan County and other counties north of Cross Plains.
They also said a snow advisory was in effect generally along and north of a line from Sterling City to Coleman, and snow accumulations from 1 to 3 inches were possible overnight.
Motorists were advised to be prepared for limited visibility and snow covered roads. Scattered snow showers will be possible throughout the rest of the area, including Brown County.
Light freezing precipitation but with no noticeable accumulations had begun falling in Brownwood around dusk Thursday.
The area is expected to get a break from the snow this weekend, but not the cold weather. The weather service said continued chilly temperatures are expected through Sunday, with another chance for precipitation throughout the area Saturday and Sunday with the possibility of a new round of wintry mix.
Meteorologists could not say with any certainty Thursday how much or exactly what type of precipitation will fall this weekend, so area residents — especially those planning to travel as the long Thanksgiving weekend comes to a close — should carefully monitor weather reports.
Temperatures are forecast to be in the upper 40s today with 5 to 10 mph winds out of the northeast. Highs may not reach 40 on Saturday, and the chance of precipitation increases from 20 percent tonight to 70 percent Saturday. The chance of rain or snow showers on Sunday is 50 percent, but temperatures should rise above 40 before sunset. Lows will be just above freezing.
