Winter Weather Update (Saturday Feb 3rd, 5 am): Wintry Precipiation likely next 24-36 hours...

Good Saturday morning, here is the latest winter weather update for the region…

 

Conditions are coming together for a winter weather event for the early morning hours of Sunday through about noon for the Western Carolinas. Cold high pressure in place today will begin to slide east as the next storm system begins to develop out in the Southern Plains. Cold, arctic air is in place today and will not be able to fully retreat before moisture begins to invade after midnight tonight. Winter Weather Advisories have been issued for the area beginning late tonight until Sunday morning...

With temperatures expected to be near the 30-degree mark early Sunday morning as moisture moves in from the west the potential is there for mixed precipitation across the Western Carolinas. It may begin as a brief burst of snow especially close to the immediate Blue Ridge but should quickly transition to freezing rain by around 7-8 am or so. The initial precip should help lower temps just below the freezing mark thanks to evaporative cooling. As we get later into the morning local temps should slowly rise to the freezing mark by roughly 11 am and then just above critical levels by Noon decreasing and ultimately ending the threat of icing.

 

Latest model data is showing modest icing potential centered across the favored CAD areas of the Foothills. Amounts could range from .10 - .25 inch ice accretion, what agrees with our current forecast thinking. Sections of Alexander, Caldwell, Burke and McDowell Counties might see the worst icing with others seeing .10 inch or less accretion.

 

 Fortunately there is no anchored high pressure to our north but small mesoscale surface highs overhead can help lock in temps right near the freezing mark.

 

Right now expect some impacts on local roadways on Sunday morning, especially anything elevated. However we don’t see enough ice buildup expected to cause issues on trees and power lines…of course we will monitor in case of any changes.
