Discussion              

Many ingredients appear to be coming together for a storm system that can have a high impact over the eastern third of the nation from later this weekend into Monday with snow, ice, rain, coastal flooding, and even high (damaging) winds on the table. There are many details that still have to be ironed out with a few days to go before this event and the main wave of energy of interest in the upper atmosphere is just now nearing the US NW coast from the Pacific Ocean.  As it stands now, the DC-to-Philly-to-NYC corridor may receive an accumulation of snow on the front-end of this storm system. The immediate I-95 corridor region may end up being the dividing line between a substantial snowfall to the north and west and a snow-to-ice-to-rain scenario to the south and east. Looking beyond the storm, the overall weather pattern likely remains quite a bit colder-than-normal for much of the second half of the month.
