At noon the temperature in the Bronx is 45°F with chrystal clear skies, expecting a high around 50°F. The storm system responsible for last night's rain has moved out of the region. In its wake we are left with very mild temperatures and fair weather, however this will be short lived. An upper level low pressure system over the Great Lakes associated with the same departing storm will move through the Northeast. Precipitation wise, this system should have enough instability to produce some light snow with little accumulations on Monday and early Tuesday as it drags a sharp cold front. The main feature with this storm will be gusty winds and then a sharp temperature drop. Temperatures will drop by some 15° to 25° by Tuesday. This will set the stage for a potential significant snow storm likely around the New Year holiday. Though it is still too early to make a precise forecast, over the past weeks NCEP forecast models have been more inclined towards a rather impressive coastal storm developing with a 1,2 punch to the region. The first round is likely on January 1st or 3rd with round two likely January 8th or so. NCEP forecast models indicate temperatures cold enough for frozen precipitation for the most part. Both scenarios have the potential to produce significant snow respectively. I want to reiterate however that this is still days away and it is too early to call any shots. Weather is very dynamic especially this time of year and it is difficult to accurately forecast a storm of this magnitude this far in advance.
