This morning a weak disturbance off the New Jersey coast is producing scattered snow showers along the immediate coast. No accumulation has been reported, however given that temperatures are in the lower 30’s this morning, the accumulation of a dusting and even possibly an inch in some isolated locations along the immediate New Jersey shore is not impossible.
Cold conditions will continue through today and into this weekend with a risk of scattered snow showers each day. Temperatures today will struggle once again in the upper 30’s over the interior to lower to mid 40’s along the coast and in urban locations. As each disturbance moves through the region, the threat for snow showers will increase and decrease, much like a passing tide. At times, much of the region will have clear skies and dry conditions. At other times, a snow showers can sit over a location for a few hours producing an surprise accumulation of snowfall.
The clipper low pressure system for Sunday is expected to remain well to the south of the Northern Mid Atlantic with Philadelphia and New York City metropolitan areas only experiencing a continuation of the snow shower threat. However, I still caution that this system has to be watched. I have seen way too many times were a clipper low pressure system around an upper low ends up much further north than forecasted even 24 hours out, so I’ll be keep an eye on that disturbance. However, right now the forecast has the upper low that forms over Vermont and New Hampshire to suppress the clipper over the southern Virginia coast, keeping much of the region to the north of any steady snowfall.
Behind this low pressure system, the cold air mass becomes even colder. Snow showers will remain a threat throughout next week. Although no wide spread accumulation is expected, these snow showers will be rather dynamic and will be capable of producing a snow burst that can catch some by surprise. Otherwise, the main story will be the cold conditions were temperatures will average well below normal. I stayed below the MOS model guidance, which is trying to play catch up to the magnitude of this cold air mass. Temperatures will range from the 10’s to lower 20’s over the interior and lower to mid 20’s along the coast and in urban locations for lows and upper 20’s to lower 30’s over the interior and mid 30’s along the coast and in urban locations for highs.
