GFS has nothing except for...Clouds. lol but cool.

NAM continues its craziness.(5 in a row!) I will hold off on calling my sister near Buffalo to tell her this model shows a foot of snow for her. 4-5" into Western CT

Not sure what Euro showed today. Havent checked.



HPC Discussion. Interior most likely means Northern CT Northward to them.

FARTHER NORTH...SHOWER ACTIVITY WILL LINGER
OVER THE NORTHEAST THROUGH THURSDAY MORNING WHILE THE ANCHORING
SURFACE LOW SLOWLY DRIFTS AWAY FROM THE COAST. COOLER AIR
FILTERING IN BEHIND THE FRONT SHOULD ALLOW FOR PRECIPITATION TO
FALL IN THE FORM OF SNOW ACROSS INTERIOR NEW ENGLAND.

Just realized... We're 2 days away from this event. LOLOL!! We do have track agreement folks. It should pass just South of NYC.

NWS Albany which serves Litchfield Mentions the CMC is further north then all models (which would guarantee Rain) and slower but disregard it.

National Weather Service Text Product Display

" MOST MODELS INDICATE THAT THE MAJORITY OF ANY PRECIPITATION WITH THIS LOW WILL PASS JUST SOUTH OF ALBANY FRIDAY NIGHT.

ONE EXCEPTION IS THE CMC WHICH INDICATES A FURTHER NORTH (AND SLOWER SOLUTION). FOR NOW...THIS MODEL HAS BEEN DISCARDED.

THE NAM IS HONING IN ON AN INTENSE FRONTOGENTIC BAND THAT COULD PRODUCE UP TO HALF AN INCH OF PRECIPITATION. THIS MODEL INDICATES MOST IF NOT ALL THIS WOULD FALL AS SNOW AS TEMPERATURES ARE BELOW FREEZING THROUGHOUT MOST OF THE COLUMN.

THE GFS AND ECMWF WERE A LOT LIGHTER WITH THE QPF BUT THESE MODELS ARE NOT DETAILED WITH TEMPERATURE STRUCTURE. PER HPC...DECIDED TO BACK OFF A LITTLE THE PROJECTED SNOWFALL ACCUMULATIONS COMPARED TO THE LAST RUN. STILL THINKING AN INCH OR TWO IS POSSIBLE ACROSS THE HIGHER ELEVATIONS...A COATING AT MOST IN VALLEY LOCATIONS."


Even Boston now mentioning a mix possible. LOL They are all playing it conservative and so they should I guess being its almost April.

It's getting quite dry up here in NH. We are down 2.5 inches of precipitation from average and quickly falling further behind. The GFS and Euro don't show much in the way of widespread precip activity for the next 2 weeks. Red Flag warnings have already been hoisted within the past week. Hopefully the pattern will just stay cooler so we don't have the warm/windy/dry combination all at once again.

I was just ready to say something like “I’m not sure about 70’s this coming week…but I do think that most of the area will see widespread highs in the 60’s F”…then I saw the newest AFD that just came out. It looks like you are right:


AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
755 PM EDT WED MAR 28 2012.

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
DRY CONDITIONS ON FRIDAY AS HIGH PRESSURE BUILDS IN FROM THE WEST. THEN...MODELS DIVERGE ON HANDLING OF A SYSTEM FOR THE WEEKEND. ECMWF AND GEM ARE WETTER...TRACKING A SURFACE LOW OUT OF THE OHIO VALLEY AND THEN SOUTH OF THE BRINGING SHOWERS FOR SATURDAY INTO SATURDAY NIGHT. GFS IS SOMEWHAT QUICKER AND DIVES THE SURFACE LOW FARTHER SOUTH...SHUTTING OFF SHOWER ACTIVITY SATURDAY AFTERNOON.

DRY CONDITIONS RETURN FOR SUNDAY. MODELS SAG A WEAK COLD FRONT SOUTHWARD TOWARD THE AREA ON MONDAY BUT SHOULD BE DRY WITH BEST MOISTURE AND FORCING REMAINING TO THE NORTH. CHANCE OF SHOWERS RETURN FOR TUESDAY INTO TUESDAY NIGHT AHEAD OF COLD FRONT ASSOCIATED WITH A SURFACE LOW OVER THE GREAT LAKES. GFS IS THE WETTER SOLUTION AND DEVELOPS A SECONDARY SURFACE LOW JUST SOUTH AND EAST OF THE AREA. SLIGHT CHANCE OF MAINLY DIURNAL SHOWER ACTIVITY PERSISTING INTO WEDNESDAY AS H5 TROUGH MOVES OVERHEAD.

HIGH TEMPS IN THE 50S FRIDAY AND SATURDAY...WARMING INTO THE 60S SUNDAY THROUGH TUESDAY. WARMEST MONDAY AND TUESDAY WITH SOME 70S READINGS LIKELY IN INTERIOR LOCATIONS.

Despite the development of an upper-level low over southeastern Canada in the next few days, the pattern will remain a progressive one. This means that the few weather systems that reach us will come and go very quickly. So it looks like some rain showers move through the Tri-State area early Thursday, then skies clear by midday, with highs in the low 50’s. Friday looks sunny and dry and Sat might see a passing shower late. Then drier and warming weather will again move through highs into the low 60’s by Sunday and maybe even 70’s early next week. The pattern remains to be on tap for warmer than normal temps as we head into April based on the GFS 7 day mean ensembles; Look at the GFS seven-day mean temps through next Wed (April 4th)…only the PNW (again) will see cooler than normal temps. The rest of the USA will see normal or above normal temps:

I feel like the storms are outpacing my radar checks. WTF. lol. Arent the temps like 40s or 50s? How is there lightning and thunder so many times today. Crazy squall line over Long Island and Atlantic heading towards ocean.

Quick Morning Update.

Track is agreed coming from The Rockies into Ohio Valley and Out the NJ coast.

GFS suprisingly went north a little from being too far south and went cooler. Giving northern CT 4-6" of snow.




NAM went a little further North with the latest giving a mix and/or 1-2" to CT and 8-10" of snow to southern Vermont and Upstate NY.



NOGAPS is warmer then the rest.

HPC/NOAA Places the Storm slightly south then the NAM.

Upton (for 4 Southern Counties). They say all Rain but cold Saturday.

A STORM SYSTEM AT THE ONSET OF THE PERIOD WILL TRACK FROM THE OHIO VALLEY FRIDAY NIGHT TO OFF THE MID ATLANTIC COAST. THIS WILL PLACE THE TRI-STATE AREA ON THE NORTH SIDE OF THE LOW TRACK...IN WHAT WILL BE A COLD RAIN. AN EASTERLY FLOW OFF THE ATLANTIC SHOULD KEEP THE BOUNDARY LAYER SUFFICIENTLY WARM FOR AN ALL RAIN EVENT. HIGHS SAT THOUGH MAY NOT GET OUT OF THE 40S WITH THE CLOUD COVER...RAIN...AND ONSHORE FLOW.


NWS Boston: (For 3 Northern Counties, not Litchfield). Dyno cooling, wet bulb would be wet snow but March surface is warm. Light snow accumulations higher terrain of CT.

FRIDAY NIGHT INTO SATURDAY...

FEEL THE BANDING OF PRECIP PSBL THRU SRN NEW ENGLAND WILL RESULT IN DYNAMIC COOLING DOWN TO THE WET BULB WHICH SHOULD BE CLOSE IF NOT BELOW FRZG. ACCORDINGLY...WOULD ANTICIPATE A WET SNOW BUT SIMULTANEOUSLY WILL NEED TO CONTEND WITH A VERY WARM SFC /AS WE ALL ARE AWARE...MARCH HAS BEEN WELL-ABOVE NORMAL FOR TEMPS/. HAVE KEPT SNOWFALL AMNTS LIGHT AND SITUATED MAINLY ACROSS NRN AND WRN MA INTO SRN NH...PSBLY INTO THE HIGHER TERRAIN OF CT. CANT RULE OUT SNOW ACROSS A MAJORITY OF THE FCST AREA...BUT ACCUMS MAY BE DIFFICULT

PRECIP TYPES LIKELY TO BE IRONED OUT AS WE GET CLOSER IN

NWS Albany (Litchfield) - Supports Snow in higher elevations. Time for Rain to change to Snow just an inch or two at most.

THERE IS SOME DECENT FRONTOGENESIS...VERTICAL MOTION...ISENTROPIC
LIFT AND LOW LEVEL JET ENERGY TO SUPPORT SOME LIGHT MEASURABLE
SNOW IN HIGHER ELEVATIONS OF THE EASTERN CATSKILLS...TACONICS AND
HIGHER ELEVATIONS OF LITCHFIELD COUNTY. IT MAY TAKE SOME TIME FOR
RAIN TO CHANGE TO SNOW FRIDAY EVENING AND NIGHT UNTIL THE COLUMN
COOLS. ANY ACCUMULATIONS WOULD BE VERY WET SNOW ON GRASSY AREAS
AND MAY BE BARELY A DUSTING IN VALLEYS AND AN INCH OR TWO IN THE
HIGHER ELEVATIONS.
