A fast-moving clipper is projected to pass just north or very close to the Washington Area on Sunday evening, likely touching off scattered showers or a few passing snow flurries. The latest European model (image below courtesy weathermodels.com) indicates this will likely remain a conversational event only with no issues on area roadways.
The North American Model (NAM) model (image below) shows rain (green) and snow showers (blue) moving through between 4pm Sunday and 2am Monday. Those of you from Garrett county eastward toward Washington county in northern Maryland could pick up a dusting from this fast-moving system.
The work week ahead will start off unseasonably cold with a gradual warm up expected Thursday and Friday.
Mid-Week Coastal Storm?
The European Ensemble Prediction System (image below courtesy WxBell) continues to develop a coastal storm offshore on Wednesday into Thursday. A few of the red “Ls” in the image below represent the potential location of a coastal low pressure system. Notice that a minority of these Ls in the image below are located off of the Delmarva coast. Forecast models can change with time, so while I’m not hopeful that a coastal storm will impact our region it’s something to keep an eye on. Nova Scotia will likely get slammed by a Nor’easter as phasing between the southern and northern branches of the jet stream occur well to our north and east of D.C. as has been the case this entire winter.
