Midweek Weather Briefing: Cold and blustery

Good Wednesday to everyone…yesterday was a shock to the system as we dealt with a cold and clammy weather regime with periods of rainfall. Today and the rest of this week will feature a different kind of  chill as a cold front has moved through ushering in a reminder that winter still has a say in the weather pattern.

 

Northwest winds are moving an airmass change into the region this morning. After some early fog expect increasing sunshine and windy conditions. Temperatures will be slow to rise today with values getting only into the mid to upper 40's. The North Carolina high country may see a few snow showers especially early on today, here in the lower elevations a few sprinkles can’t be ruled out across northwest sections of the coverage area but it should remain dry for most everyone.

 

Once the sun drops past the western horizon temperatures will be quick to tail off. Winds will remain elevated and that may prevent temperatures from really bottoming out, regardless some upper 20’s and lower 30’s are expected for tonight under mostly clear skies.

With northwest flow still in place the next disturbance will move through the Western Carolinas on Thursday delivering a fresh batch of cold air. The mountains could actually see a better snow chance with Thursday’s disturbance and here east of the Apps it will be another cold and breezy day with low to mid 40’s expected.

 

Winds will start to calm down Thursday and that could result in a widespread freeze first thing Friday morning with temperatures in the mid/upper 20’s. The growing season hasn’t officially started across the Foothills and Western Piedmont but the warmth of February did result is some budding trees and plants. So the upcoming cold will impact that somewhat.

As you can see in the upper levels of the atmosphere a trough located over the Northeast US is keeping the flow at the upper levels out of the northwest. Additional shortwaves across Western North America will slide down longwave trough keeping a cold air source intact for a while.

The next series of short waves could bring a few rain showers to the region for the weekend.
