Happy Monday everyone! I hope that you had a wonderful weekend! Did you get to check out the eclipse last night? It was beautiful. If you was out last night watching it, you know how cold it felt. It's a shock to the system.
A blast of cold Arctic air pushed through the area on Sunday. That has lead to well below normal temperatures for today and tomorrow. Highs today under sunny skies will barely reach the freezing mark. Tonight under clear skies, lows will plummet into the teens. Tuesday we will see a slight rebound as temperatures across the Interstate 40 corridor will rise into the mid 30's for highs, still well below average.
Speaking of Tuesday, as high pressure exits the area, a cold air daming (CAD) event will begin to set up. Return flow from the Atlantic and Gulf of Mexico will begin, that sets up some shallow moisture with upslope over Western NC, including the forecast area. Currently with cold dry air still in place, the onset of precipitation could start off as a snow/sleet mixture, before warm air aloft kicks in and we transition to freezing rain/drizzle.
This could provide for up to .10" of ice accretion across the Interstate 40 corridor including (McDowell, Burke, Caldwell, Alexander, Catawba and Northern Lincoln Counties) this would happen as the work day begins. Travel concerns could arise as ground temperatures and ambient temperatures would allow for icy roads, and ice build up on trees and power lines.
This should turn to rain by Wednesday afternoon. Rain continues through Thursday morning before the system departs the area. That will usher in cold temperatures again by the end of the week into the weekend.
Have a Great Day!
