Don’t Get Too Hyped Up For Thursday Night’s Frontal Passage.... Get Excited About The Pattern It Sets.

Good Wednesday Morning to you all. I apologize for the lack of briefings the past couple of days. Certainly have been busy with some other things.  

Last night’s frontal passage was a rude awaking to many as Old Man Winter came howling back into the area. High pressure is moving overhead bringing much calmer wind conditions than what we had 24 hours ago. Temperatures are quickly falling off too in response to the calmer conditions. Radiation also cooling in full effect. Temps end up in the mid and upper 10’s by the time sun rises.  

That high pressure will move off the coast by later this evening and then out to sea. On Thursday another cold front will move into the area. Ahead of the front strong SW winds will develop, increasing lift and eventually developing a narrow shield of rain across the Ohio and Tennessee Valleys.

As the front approaches the mountains Thursday Evening it will slow and the precipitation shield should start to erode. The front picks moves East leaving the cold air back across the mountains. This looks like it will be one of the classic events where the cold chases the moisture out of the area. By predawn Friday the front is moving East across the Carolina Piedmont taking precipitation with it. Right now it appears as though light rain will be the predominate type across our area although I could see a flake or two mix in just before it ends.

Behind the front Arctic air spills into the region. This will only allow temps to get back close to 40° with breezy conditions.

Saturday will be the best out of the two days this weekend, allbeit cold. Temps top out in the upper 30’s.

High pressure will move off the Carolina Coastline by Saturday Night. Another cold front approaches on Sunday Morning, developing a wave of low pressure along it in the ARKLATX. The eventual track and depth of this low pressure are key. Scenario 1 would be a snow/sleet Chance across our area while Scenario 2 brings the low up into the Carolinas allowing for liquid rain.

Scenario 2 would be a little ice mix with rain.  

 

This is a huge pattern shift for us as we head into the second half of Winter. Very cold air masses breaking free from the Arctic and coming Southeast into the Carolinas. Does all of that cold link up to a winter storm? It is yet to be seen. We will watch it though.
