Discussion

Our relentless Arctic cold weather will continue through next week and the lowest temperatures are likely still to come. A fast-moving “clipper” system will drop southeastward into our area by tomorrow and it can produce some accumulating snowfall in the Mid-Atlantic region despite its lack of available moisture. With cold air firmly in place, the "snow-to-liquid" ratios will be quite high (~20:1) and this may result in a dusting to an inch or two despite the limited "precipitable water" content. This “clipper” system will then usher in a fresh frigid Arctic air mass for Sunday, Monday and Tuesday and this will be an extremely cold period for much of the eastern US. In fact, temperatures around here could start the new year on Monday morning not far from the zero degree mark in many spots. Looking ahead, there may be another threat for snow during the middle of next week, but odds currently favor that potential system forming a bit too far off the coastline for any important impact around here. Stay tuned.
