A cold Canadian high pressure system is building in behind a cold front that moved trough the region on Saturday. This high pressure system is going to give the area lows Sunday morning about 15-20 degrees colder than normal. The Upstate will dip into the upper 20s and the mountains will dip into the lower 20s by daybreak on Sunday. In addition to cold air, the winds will be gusty through early Sunday afternoon. This is especially true in the mountains where the higher elevations are under a wind advisory through at least noon on Sunday. Combine the winds with the cold temperatures and wind chills will be near zero Sunday morning in the mountains and will be in the 20s Sunday afternoon. Actual highs will be in the lower 40s in the Upstate and lower 30s in the mountains. Also,with dry and windy conditions the region also will have an elevated fire danger through Sunday.
After Sunday, our weather stays chilly and a low pressure system will approach the area from the Gulf of Mexico. If you have lived in the area very long and have followed our weathercasts, you know this can be the set up for wintry weather in the Western Carolinas. It is all about the timing of the cold air and moisture. In this set up, cold air will be moderating some but still in place across our area. Moisture will be coming in from the Gulf of Mexico and it does look like a portion of our area will see some wintry precipitation mainly in the form of freezing rain and possibly some sleet/snow early Tuesday. Current model trends are keeping the bulk of this wintry weather in the mountains and Western NC. Accumulations will be likely but amounts are a bit tricky. Generally light accumulation amounts are expected. However, even with light amounts travel could be impacted early Tuesday morning when the onset of the moisture takes place. For the Upstate, right now we are keeping our precipitation forecast as rain, but we will watch this very carefully over the next couple of days. I have attached a graphic from the National Weather Service that shows the areas with the best likelihood of some wintry weather accumulation. Once we get into Monday, the models should have a better handle on the temperature and moisture profiles for not only the mountains but the Upstate too.
Once we get into Tuesday afternoon, temperatures will moderate to above freezing so most everyone will then have rain. The threat for rain continue into Tuesday night and into Wednesday. Then another shot of cold air is forecast to move into the area. Again the timing is everything. If this cold air makes it into the region before all of the moisture moves out, then we have another possibility of some more wintry precipitation during the day/evening on Wednesday. Again, as the week progresses we will have a better handle on this next weather system's impact on our area.
Therefore, keep checking with FOX Carolina and our team of meteorologists for the updated weather forecast next week.
