NYC Weekend Weather – Dec 6, 2019

An arctic front swings through today, bringing a blast of cold air behind it going into the weekend. Temperatures will rebound dramatically going into the start of next week with an approaching storm system turning winds to the south. We’ll see high temperatures going from the upper-30s to the mid-50s by Monday.

Rest of today – mostly cloudy with a high temperature in the upper-40s. Chance of rain this evening with the passage of an arctic front. Overnight lows cooling into the low-30s with clearing skies.

Weather Prediction Center surface forecast for 7AM Saturday

Saturday – high pressure builds behind the arctic front bringing sunny skies but a much colder polar airmass with high temperatures struggling to hit 40ºF. Overnight lows drop into the mid-20s.

Sunday – high pressure center moves off to the east, allowing for warmer return flow from the south. This should allow temperatures to be a touch warmer than Saturday, in the low-40s. Overnight lows are expected to bottom out around 40ºF before actually rising due to an incoming storm system turning winds to the south.

GFS model output for 1PM Monday, a low-level jet at 850 mb with winds in excess of 40 knots is evident, along with pretty high values of relative humidity.

Monday high temperatures continue to climb into the mid-50s with deep layer south-southwesterly winds. Increasing chances for rain as a cold front approaches from the west. Heavy rain is possible given a possible tropical moisture connection. Overnight lows barely moving into the low-50s.
