The first weekend in the new year starts off wet and mild with a complex storm system moving over the Eastern US. Things will settle down by Sunday with a cool down coming behind this storm system. Temperatures start to rebound early next week. In general, high temperatures will trend above normal for this time of year by 5°F, topping out in the mid-40s or higher.

Rest of today – periods of drizzle during the afternoon before a second round of steadier precipitation possibly later this evening. High temperatures in the low-50s with the warming influence of westerly flow ahead of the second frontal boundary shown below. Overnight lows in the mid-40s.

Saturday – rain chances continue during Saturday. Like Friday though, the best dynamics and moisture for heavy rain seem to bypass NYC itself. This may result in more periodic rainfall on the light side. Onshore flow from the northeast should continue to keep temperatures mild, around 50°F. Overnight lows will drop into the low-30s as the storm clears and winds turn to the north and northwest.

Sunday – a mostly sunny day expected with breezy northwesterly winds. High temperatures cooler, in the low-40s. Overnight lows remain in the low-30s.

Monday – high temperatures in the mid-40s with mostly sunny skies and continuing windy conditions. Overnight lows in the low-30s.
