(11/9) Warm to Cold This Week; Some Flake Potential Thursday Night

(11/9 630 pm)

This week will be a tale of two halves in regards to temperatures across the area.  Lots of sunshine and light southerly flow thanks to high pressure working off the coast will allow highs to climb into the upper 50s to low 60s Monday and Tuesday.  Wednesday will be our transition day as a cold front pushes through bringing much cooler weather for the end of the week.  This front looks moisture starved so any light showers should be mainly confined to the highlands of West Virginia.  Highs in the Shenandoah Valley will struggle to reach 50 on Thursday...and likely only in the low to mid 40s Friday and Saturday.

Once this frontal boundary pushes will get hung up somewhere along the Carolina Coast like we see so often this time of year.  Models have been back and forth on the idea of a wave of low pressure developing along this washed-out front.  At the same time...a piece of energy will be dropping southeast out of the Great Lakes towards the Ohio Valley before pivoting northeast into New England.  This leaves us kind of caught up between the two for the Thursday night-Friday morning time frame.  With cold air in place behind the these two systems develop and interact could lead to some snow flurries/snow showers across the state. This could include areas east of the mountains as well.  This will not be a major storm by any means but it's always an exciting time to see those first flakes so figured I'd mention the potential.
