Another large storm system is expected to bring light freezing rain and freezing drizzle Wednesday morning for parts of the Carolinas before changing to very heavy rain Wednesday Night through Thursday Morning.
Moisture is increasing over the Carolinas this evening and will continue through the overnight hours. Temperatures are expected to be below freezing across much of the foothills and areas north and west of I-85 tomorrow morning. As rain and drizzle begins to fall tomorrow morning, it is expected to freeze on contact.
The good news is moisture will be light, which should limit accumulations. The bad news is it does not take much freezing rain to cause issues on the roads and bridges, and I expect there will be travel issues tomorrow from Asheville to Morganton, Hickory, Statesville, Wilkesboro, Boone, Winston-Salem, and Greensboro. Areas shaded in purple are under a Winter Weather Advisory for tomorrow morning, and these areas have the best chance of seeing freezing rain.
Once the freezing rain threat ends, we turn our attention to the cold front that will bring very heavy rain. The heavy rain enters the mountains Wednesday afternoon and will move towards the coast by Thursday afternoon. The GFS computer model shows the progression quickly across the Carolinas.
This line of rain is expected to drop 1-2 inches of rain from the mountains to the coast. Eastern facing slopes in the mountains and foothills may receive up to 3 inches of rain, which may lead to isolated flooding concerns.
Behind the front, drier air moves in for this weekend. The bad news is temperatures are expected to be below average for this time of year.
