Winter Weather Update (Wednesday 2 pm)


Good Wednesday afternoon to everyone, we continue to monitor the latest on a dynamic storm system that will impact the Western Carolinas in the next 24 hours, a system that will deliver a multi-season weather threat...




The sub-tropical jet stream continues to provide moisture-laden weather systems for the Southeast US and this next rain event will be no exception. A closed off upper low across Arkansas has pulled up another slug of moisture throughout the atmosphere. A surface low later today will move from the Gulf Coast up into the Interior Southeast. Then by tomorrow a secondary low will begin to form off the Carolina Coastline. This is a textbook Miller-B cyclogenesis.


Meanwhile a surface high across the Midwest will move into New England by tomorrow and will begin to funnel in colder air at the surface along and east of the Appalachians.






Light mist and drizzle will continue to increase through the afternoon hours today with temperatures remaining steady in the 40's. By tonight the bulk of the moisture from this next storm system will start moving in from the south. A more steady rainfall will move into the Foothills by mid evening with a gradual transition to the northeast through the entire coverage area toward midnight.





By the early morning hours of Thursday the cold air draining in from our north will begin to interact with the moisture...some freezing rain and sleet may begin in the high country of Western Carolina. Meanwhile temperatures here in the lower elevations will still be in the mid 30's along/north of Interstate 40 with upper 30's along and south of US 74...






Then once we get to the pre-daylight hours of Thursday cold air continues to drain into the Foothills and with dynamic cooling going on we may begin to see a few issues with icing in our Foothill Counties. Temps at this point will be in the 32-34 degree range across the area. The early morning hours of Thursday up through 10 am will be the timeframe in which impacts off the higher terrain will be greatest...



Winter Weather Advisories are currently in effect for the lower elevations of Alexander, Burke, Caldwell and McDowell Counties through Tomorrow PM with Winter Storm Warnings in effect for NW Sections of Burke, Caldwell and McDowell Counties..including communities such as Little Switzerland, Jonas Ridge and Globe.





In addition to the winter weather threat, heavy rainfall is expected for all parts of the coverage area...Flood Watches are in effect through Thursday Evening with 1-3 inches of rainfall possible...







In summary...here are the key points in regards to the evolution and impacts from this next storm system. We will be updating things here at the website throughout the next 24 hours...
