Winter Storm Warning has been issued for NW Burke, NW Caldwell, and NW McDowell Counties. 2/10" -3/10" of ice possible in these areas. Icy roads, and scattered power outages probable.
High Pressure will move into the Northeast. This high pressure will be transient, which means it doesn't anchor in place. That will supply cold air into the area and create Cold Air Damming. Moisture will stream in from the southwest. We could see it initially start as a sleet/rain or snow/sleet/rain mixture. It should change over to freezing rain by midnight. Cold air continues to deepen over the area through Wednesday morning.
Warm air aloft will slowly erode the cold air wedge. It could take several hours for this to happen. Temperatures aren't expect to warm above freezing until sometime Wednesday afternoon. So it is likely we will see closings, cancellations and delays Wednesday Morning.
Air temperatures are forecasted to rise above freezing by mid afternoon. Some locations will be slower to warm. Precipitation should start to dissipate over the area by mid to late afternoon Wednesday. This will allow the temperatures to warm.
Thursday another front moves into the area, but with the strengthen Bermuda high, that will stall the front over the Carolinas. That will allow another slug of moisture to move into the area on Friday, and yet another slug will move in the area on Saturday. So highs Thursday - Saturday will be in the upper 40's to low 50's, with several rounds of rain. We may see a Flood Watch issued at some point.
Sunday the wedge breaks down, and temperatures soar into the 60's and possibly low 70's. This will be accompanied by another cold front. The front could link up with daytime heating to create some gusty thunderstorms on Sunday. This will lead to a dry and somewhat sunny Monday. Then we get back into a wet pattern for the next week.
