Winter Weather Will Impact Friday Night and Saturday Morning

Ice Storm Warning (pink) & Winter Weather Advisory (Purple) Ice Storm Warning (pink) & Winter Weather Advisory (Purple)

An Ice Storm Warning and a Winter Weather Advisory are in effect for the region through Saturday at noon. The Ice Storm warned area has the potential receive a quarter of an inch to half an inch of ice while the area under a Winter Weather Advisory has the potential to receive from a trace amount to a quarter of an inch of ice. 

Extreme caution should be taken while conducting vehicles during this time. Slick conditions are expected on roads, especially on bridges and overpasses as temperatures on these surfaces can run 6 degrees below the surface temperatures! Temperatures elsewhere will flirt with the freezing mark. This is dangerous because precipitation has the potential to change between freezing rain and liquid rain. Rain and freezing rain will be difficult to distinguish at night. Visibility will be reduced at times. Wind chills will be in the lower 20s and teens through the night!

Saturday afternoon, temperatures will warm above freezing turning all precipitation to liquid rain. Temperatures in some areas will fall below freezing again Saturday night, so some remaining water on the ground may re-freeze. Rain continues through Sunday. 

Science time! A strong arctic cold front moved through the area Friday morning. The shallow layer of cold air impacting West Texas is responsible for the drop in temperatures throughout the day on Friday. We also have moisture running running through the region from Hurricane Sandra in the Pacific. The jet stream associated with the cold front supported the lift needed for the production of rain. The shallow layer of cold air was just cold enough to cause rain to refreeze right before hitting the surface and that is the reason for the freeing rain. Above freezing temperatures will return on Saturday afternoon, however, moisture from Hurricane Sandra will still be in the area bringing in the rain through Sunday.
