The National Weather Service in San Angelo has issued a Winter Weather Advisory for accumulating snowfall, which is in effect from 9 PM this evening to 9 AM Friday.

Light to moderate snow is possible, and potentially significant snow may impact the area causing hazardous travel conditions. Roads and bridges will become slick and icy.

Accumulations of 1 to 3 inches of snow are possible.

A Winter Weather Advisory means that periods of snow, sleet, or freezing rain will cause travel difficulties. Be prepared for slippery roads and limited visibilities and use caution while driving.

Accumulating snow is expected across the Concho valley, Southern Big Country and Heartland areas.

A strong upper level storm system will approach West Texas today and move across the region on Friday.  With the approach of this system, precipitation is expected to develop this afternoon across the western Concho Valley. The precipitation could initially begin as a light mix of rain and snow, but will likely change to snow this evening. The precipitation will overspread most of West Central Texas tonight, and will be mostly in the form of snow across the Concho Valley and Big Country. A mix of rain and snow is expected across the Heartland and northwest Hill Country, before changing to all snow by late tonight.

Hazardous travel conditions are expected to develop with the accumulating snowfall and temperatures dropping below freezing.
