Heads UP! Train of storms coming to the NE USA

[Parts in ALL CAPS are National Weather Service analysis,
parts in lower case are my summaries]
Part 1 – Sunday
ACROSS PASSAIC/W BERGEN COUNTIES IN NJ THE LOWER HUDSON
VALLEY [north of I287) AND CT…. PRECIPITATION STARTING AS SNOW…
THEN GRADUALLY TRANSITIONING TO
RAIN SUNDAY MORNING AS THE LOW LEVELS OF THE ATMOSPHERE WARM TO
ABOVE FREEZING. THESE AREAS COULD SEE UP TO AN INCH OF SNOW
BEFORE CHANGE OVER.

HOWEVER…IT APPEARS THERE WILL BE ENOUGH COLD AIR DAMMED AT THE
SURFACE ACROSS PORTIONS OF ORANGE…PUTNAM…AND FAIRFIELD
COUNTIES TO SUPPORT A PERIOD OF FREEZING RAIN DURING THIS
TRANSITION SUNDAY MORNING. ANY ICE ACCRETION SHOULD BE LESS THAN A
TENTH OF AN INCH…WITH MOST AREAS RECEIVING A GLAZE. THE DEEPER
VALUES IN ORANGE AND PUTNAM COUNTIES THOUGH COULD SEE UPWARDS OF
AROUND 0.05 INCHES OF ICE.

[Rain for the rest of us]

Part 2 – Late Monday into Tuesday
ALL GUIDANCE SUGGESTS A LULL IN THE PRECIPITATION OF 6-12 HOURS
BETWEEN THE DEPARTING COASTAL LOW AND THE APPROACHING MAIN STORM
SYSTEM FROM SOME POINT MONDAY MORNING INTO MONDAY AFTERNOON.

FOR NOW IT APPEARS RAIN ASSOCIATED WITH THE PRIMARY SURFACE LOW
ARRIVES LATE MONDAY AFTERNOON.

[storm comes right over us – but not a severe storm]
THE BULK OF THE PRECIPITATION ACROSS THE TRI-STATE WILL BE IN THE
FORM OF RAIN MONDAY NIGHT AND TUESDAY. COULD SEE ENOUGH COLD AIR
WORK IN BEHIND THE STORM TUESDAY NIGHT MAINLY N INTERIOR ZONES
COULD SEE SOME SNOW MIX IN LATE TUESDAY NIGHT.

Part 3 – Friday
[next storm goes to the northwest of the NYC metro area]
…WITH ITS
TRAILING COLD FRONT…CROSSING THE AREA
FRIDAY. FOR NOW APPEARS COULD BE COLD ENOUGH FOR A RAIN SNOW MIX
LATE THURSDAY NIGHT/FRIDAY MORNING ACROSS INTERIOR ZONES BEFORE
CHANGING TO ALL RAIN THROUGHOUT BY FRIDAY AFTERNOON.

Christmas week is windy and much colder with the Friday storm
bringing much colder air to our area into Christmas Eve.

I haven’t looked beyond that yet.
I recommend the Washington Post Capital Weather Gang’s posts
on the possibility of a DC white Christmas to learn more about
upcoming storms.
