Heads UP! Watch the Weather Forecast for Thanksgiving Eve in the northeast US!

Sunday evening update from the National Weather Service NYC office’s forecast discussion…

WITH ONLY A MARGINALLY COLD AIRMASS TO START…THIS TRACK WOULD
BRING MAINLY RAIN TO LI/SE CT…RAIN/SNOW MIX FOR NYC/NJ METRO AND
SW CT…AND MAINLY SNOW WELL N&W OF NYC…CHANGING TO ALL SNOW WED
NIGHT FOR MOST IF NOT ALL OF THE REGION
AS THE LOW DEEPENS AND TRACK
NORTH. THIS MESHES FAIRLY WELL WITH WPC…WITH A LOW PROBABILITY OF
SEEING WARNING LEVEL [>6inches] SNOW RELEGATED TO INTERIOR PORTIONS OF NE
NJ…LOWER HUDSON VALLEY..AND SW CT…AND ADVISORY LEVEL SNOW [3 inches]
POSSIBLE INTO NYC METRO AND COASTAL SW CT SUN NIGHT. CONFIDENCE IN
THESE VALUES IS LOW TO MODERATE AT THIS POINT BASED ON ABOVE
MENTIONED SPREAD. PREDICTABILITY TOO LOW WITH THIS DAY 4 EVENT FOR A
DETERMINISTIC STORM TOTAL SNOW FORECAST

When the National Weather Service New York City area office says this:


"WILL NEED TO MONITOR FUTURE MODEL TRENDS AS
THIS WILL BE OCCURRING DURING THE BUSIEST TRAVEL DAY OF THE YEAR.
UNCERTAINTIES EXIST IN HOW FAR WEST THE PRECIPITATION SHIELD WILL
REACH...AND THE EXTENT OF COLD AIR IN THE LOW LEVELS THAT WILL BE
AVAILABLE. SYSTEM MOVES NORTH AND EAST ON THURSDAY WITH BELOW NORMAL
TEMPERATURES IN THE 40S.

Keep an eye on your local forecast
and the forecast for places you will be traveling to
(and the places in between!)

They are watching how the forecast models construct a storm off the east coast for Wednesday night. Too close with cold air coming in can lead to snow. It wouldn’t take much to throw Thanksgiving eve traffic into a tailspin. But lots has to happen before snow could be in the forecast.
Stay tuned!
