Harvey asked me to do it...although I don't see it but remember Tuesday is Roll Back the Clock Day at MRG...if this hits early, that's where I'll be
MODELS DISAGREE REGARDING MONDAY NIGHT AND TUESDAY. ALL MODELS
LOOK TO GENERATE SOME KIND OF EAST COAST STORM...BUT THE TIMING
INTENSITY...AND TRACK VARY WIDELY. THEREFORE AT THIS TIME
WILL GO WITH HPC WHICH FORMS A WEAK LOW NEAR CAPE HATTERAS
TUESDAY MORNING WITH A STRONGER LOW OVER NORTHERN FLORIDA. IT
APPEARS TO BE CLOSEST TO THE GEM...AND TO A LESSER EXTENT...
THE ECMWF. THE LOW OVER FLORIDA MOVES TO NEAR CAPE HATTERAS BY
TUESDAY EVENING AND PRETTY MUCH CAPTURES THE ONE TO THE NORTH
AS IT INTENSIFIES. IT IS THEN FORECAST TO MOVE TO SOUTH OF LONG
ISLAND BY WEDNESDAY MORNING...AND CONTINUE TO THE GULF OF
SAINT LAWRENCE BY THURSDAY MORNING...WITH A WEAK RIDGE OF
HIGH PRESSURE MOVING IN FROM CANADA AS THE LOW PASSES BY.
LOWS MONDAY NIGHT WILL AGAIN BE COLD...ESPECIALLY NORTH
WHERE CLOUDINESS WILL BE THINNEST...RANGING FROM AROUND
15 BELOW NORTH TO AROUND 5 ABOVE SOUTH.
ON TUESDAY...THE ECMWF SPREADS PRECIPITATION INTO THE REGION
AHEAD OF THE SYSTEM OFF THE CAROLINA COAST. THE PRECIP WILL
START AS SNOW AND SHOULD REMAIN AS SNOW MUCH OF THE DAY.
TEMPERATURES WILL MODERATE SOME WITH HIGHS GENERALLY IN
THE 20S. WITH AN 850 HPA FLOW OFF THE OCEAN AND SURFACE
WINDS FROM THE NORTH OR EAST...COLD AIR IS LIKELY TO BE
TRAPPED UNDER THE WARMER AIR ALOFT...RESULTING IN THE
POSSIBILITY OF SLEET OR FREEZING RAIN FOR A WHILE TUESDAY
NIGHT. AT PRESENT WE ARE NOT LOOKING FOR THE WARM NOSE TO
GET FAR ENOUGH NORTH TO AFFECT THE CAPITAL REGION. LOWS
TUESDAY NIGHT WILL RANGE FROM NEAR ZERO IN THE FAR NORTH
TO AROUND 20 SOUTH. ON WEDNESDAY COOLER AIR MOVES IN ALOFT
WHICH WOULD CHANGE FREEZING PRECIP BACK TO SNOW...EXCEPT IN
THE MID HUDSON REGION WHERE IT MAY GET WARM ENOUGH AT THE
SURFACE FOR A BRIEF PERIOD OF MIX. HIGHS WEDNESDAY WILL
RANGE FROM THE MID 20S TO THE MID 30S. AMOUNTS OF PRECIP
ARE A TOSS UP AT THIS TIME...WITH THE ECMWF RATHER JUICY
OVER LITCHFIELD COUNTY WITH OVER AN INCH OF LIQUID AND
THE GFS WITH A TRACK FARTHER OFFSHORE HAVING HARDLY ANY
PRECIP AT ALL. HAVE CHANCE POPS SOUTH AND WEST TUESDAY
AND OVER THE ENTIRE AREA TUESDAY NIGHT AND WEDNESDAY.
well the GFS is back on board with a supper sick looking system..This monster gets cut off and is load with qpf..I'm just a little nervous the low will cut off further west, thus sucking the low into NY state...Still many more runs to go..
Well things are starting to look a LITTLE clearer..Just a little..All models show a pretty strong system moving up the east coast. The question is how far off the coast. The GFS keeps flip flopping , one run is a coast huger then next it's out to sea.
The NAM was the slowest and further west , bringing Rain to the coastal cities and a nice dump for all of the mountains..That said , the latest 12z run is a bit more progress and further east..There is great potential with this system..
