Midweek Weather Briefing: Trough continues to dominate local weather pattern, some changes are coming soon

Good Wednesday to everyone…a cold weather pattern continues for the mid-week time-frame. As the day begins the Western Carolinas and the Eastern US continues to be dominated by a deep long wave trough. The major winter storm that impacted the East Coast earlier in the week is now in Canada, here in our part of the world disturbances continue to slide down the back side of the trough. One of those blew through overnight and has sparked another round of snow showers in the high country and a few flurries in the Foothills.

Skies today should be mostly sunny by late this morning but windy and cold. High’s today will remain in the mid to upper 40’s, a good 15 or so degrees below mid-March norms. By tonight winds may begin to relax some and that will allow for a chilly night with temperatures getting down into the 20’s and low 30’s.

 

By Thursday the longwave trough will start to slide east and allow upper level winds to flatten out more from the WNW, while at the surface a westerly flow will also form. That will promote a warmer afternoon with temperatures getting back up into the 60’s.

 

On Friday westerly flow takes over and a small piece of energy from the Western US will cross the Rockies and eject eastward, this will lead to an unsettled end of the week and start to the weekend. Clouds will first increase and then a few showers will slide east starting Friday afternoon and reaching its crescendo on Friday night. Right now rainfall amounts look fairly light with moisture content being limited at this time.

 

Temperatures on Friday are expected to be in the 60’s with Saturday’s high’s in the 50’s and low 60’s based on the amount of clouds expected.

 

Have a great Wednesday!
