Winter weather possible later this week, high uncertainty remains

Merry Christmas to everyone across the Foothills and Western Piedmont. Our weather team continues to monitor the latest on the potential for some wintry weather that might impact the region later this week.


Looking over the computer model guidance from this morning there wasn’t a whole lot in the way of convergence toward one kind of forecast solution for late this week. We still expect some upper level disturbances to slide along the Gulf Coast beginning on Thursday and sliding through Thursday night/Friday morning. That disturbance will help allow moisture to overrun a cold arctic airmass that will be firmly in place across the Carolinas.


The big question right now is just how much moisture will move toward the Western Carolinas? There remains plenty of uncertainty in regards to amounts at this time. The trend if anything over the past few model runs have been toward smaller precipitation amounts.


With this update plenty of questions remain as you can see in the graphic below. Also, there is no change in the winter storm index at this time.

Our next update on this potential winter weather will be on Tuesday, hopefully we can begin to narrow this down a bit more by then.
