PRELIMINARY WINTER STORM IDEA FOR SATURDAY



The question that still needs to be ironed out for the upcoming weekend storm are as follows:
a). How strong will the storm be?  A stronger storm would tend to drive warmer air up the coastal plain and make for more of a mixed precip event for the city and coast. However, a weaker storm would actually mean MORE SNOW for the coast; in this scenario, warm air would not get here in time to change the precip over to a mix. And with cold air in place, it would be able to hold on for the duration of the storm.

Ironically, the opposite effect would take place further away from the coast. Well inland, the strong storm option would crush the Hudson Valley and points to the north, as copious amounts of moisture would be thrown up into the higher elevations, with very little changeover to plain rain. However, a weaker storm would be robbed of moisture, thus only giving the region to the north of the coast a light to moderate storm...

Having fun yet...?

A WINTRY WEEK OF WEATHER IN THE MAKING...

An active, cold wintry pattern has established itself over the norther tier of states. As a result, the region is primed for bouts of light to perhaps moderate snowfalls as well as significant cold, even by December standards.

Current Snow Cover


On Tuesday,  a storm system will brush the region with a light snowfall, particularly for the city band coast. Timing looks to be in the afternoon.

My thinking...Not an official forecast...

By late week, attention will shift toward how long and how strong a bitterly cold air mass will affect the region.

Intellicast


 Temps will likely stay below freezing during the day beginning on Thursday and into Friday.

The weekend is problematic. There is some concern for potentially extreme cold by the weekend, but more than the usual amount of uncertainty exists.

Another shot at snowfall will come late this weekend and early next week, as a storm makes a move out of the southern plains states towards the east coast.

Frequent updates will be necessary this week...
