Ligth Snow and Then a Bit Warmer Next Week!

Update: 6:15 am Wednesday

Models continue to shove the low pressure deep into the Gulf of Mexico and weaken it before a new low pressure takes over and heads up the coast. This leaves most of the western Carolinas in the rip of zone for snow. I do want to caution everyone to be prepared. It would not be out of the realm of possibilities for the low pressure to stay further north and stronger than the models are saying. Both the last two storms that have hit the Ohio Valley have had more moisture to work with and were further north/west than the models had forecast.
Having said that, here is a Map of my interpretation of what will happen today through tomorrow.

Heavy snow has developed over Oklahoma, north Texas and will push into Arkansas today. As the low pressure drops into the northern Gulf of Mexico and weakens, a streak of moderate snow will push out through the Tennessee valley and into south western North Carolina. The primary low pressure will continue to weaken and eventually dissipate as it transfers energy to a new low pressure developing on the Carolina coast. The new low pressure will begin to intensify rapidly causing some moderate to heavy snow accumulations in the coastal plain of North Carolina and southeast Virginia. This low will be too far away to bring any heavy moisture our way. So you can see the rip of zone in western and central North Carolina.
*** It would not take much for that band of moderate snow to streak just a little further east in the the north Mountains and Foothills. Be prepared even though the official forecast is just for 1-2". ***

Forecast:

Mountains-

Boone area: Snow begins between 7-9 pm tonight. 1-2" locally, 3" possible.

Asheville and southwestern mountain area: Snow begins between 7-9 pm tonight, 2-4" locally 5"

Foothills and Piedmont area: Snow begins between 8-10 pm tonight, dusting - 1" locally 1-2" especially in far southern foothills (Henderson to Rutherford) and far northern foothills (Patterson to Wilkesboro).

Snow Map: (Subject to change today as I watch the radar and see how this storm holds together heading east)
