Midweek Weather Briefing: Sunshine will be at a premium in the short term...

Good Wednesday to everyone across the Western North Carolina Foothills and Western Piedmont…

 

We’re in the transition from a mild airmass to a more winter-like regime across the Eastern part of the US. A frontal boundary swept through the region last night driving  moisture in and out of the area. Rainfall totals turned out to be pedestrian, in the range of about ¼ inch on average.

 

The deeper moisture has moved out  but will stall close enough to where clouds are going to be hard to push out. Water Vapor image this morning shows a stream of moisture content hovering over the southern tier of the country. This could be the start to a multi-day period of more clouds than sun.  Also the nature of the cold air behind this initial front is shallow which means it is having some difficulty getting east of the Appalachians but it will slowly make inroads.

For this afternoon with abundant clouds, high’s will slowly rise into the low 50’s. Tonight we’ll have seasonably cold conditions with lows in the 30’s. Thursday will turn out in a similar fashion as well, a good amount of clouds keeping temperatures below average (40’s to around 50) for early December.

 

As we get into Thursday night and Friday, southern stream energy will begin to organize along the Gulf Coast and could run along the Southeast Coastline through Friday night. That moisture depending on the depth of it will have some marginally cold atmospheric conditions to work with. We still have a slight chance of rain and wet snow flakes in our 7-Day for Friday timeframe. This still looks to be a nuisance event at the worst. Temperatures if this were to occur will be above the freezing mark which limits impacts…we’ll have additional info on the potential for a couple snowflakes after the get a look at the early afternoon model runs.

 

Northwest flow will eventually kick this moisture and cloud plume far enough to the east by Saturday to finally bring sunshine back to the region…but it will come at a price and that’s some cold weather as cold reinforcements on northwest flow are coming and lining up one after another.

 

High’s for both Saturday and again on Sunday will be in the 40’s with sunshine with night time values in the 20’s…those numbers are a good 6-10 degrees below normal.

We might have just a brief one-day relax on Monday (low 50’s) before the next piece of energy in this parade of disturbances blasts through on Tuesday lowering the temps once again.
