SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY/...

INCREASING CONSENSUS FOR A MAJOR NOREASTER THURSDAY NIGHT INTO

APRIL FOOLS DAY.

 

 

 

 

THURSDAY SHOULD START AS A RELATIVE LULL BETWEEN THE SYSTEMS.

FORECAST SOUNDINGS ARE PRETTY SOCKED WITH LOW LEVEL MOISTURE AND THE

NORTH TO NORTHEAST FLOW IS NOT CONDUCIVE TO CLEARING. SO WE MAY HAVE

MORE LIGHT RAIN OR DRIZZLE EARLY, A BREAK MID DAY AND THEN THE ONSET

OF PRECIPITATION BY THE END OF THE DAY. WE BACKED OFF ON THE GFS

TIMING SOMEWHAT AS IT REMAINS THE FASTEST MODEL. THE LACK OF A

SURFACE HIGH PRESSURE TO THE NORTH WILL KEEP THE BOUNDARY LAYER

RELATIVELY MOIST AND WET BULB TEMPERATURES ABOVE FREEZING. WAS

CONSERVATIVE WITH MAX TEMPS, MANY PLACES BELOW STAT GUIDANCE AGAIN

BECAUSE OF CLOUDS AND ONSHORE FLOW.

 

COME THURSDAY NIGHT AND EARLY FRIDAY ALL BETS ARE THEN OFF AS THE

LOW IS FORECAST TO INTENSIFY FAIRLY RAPIDLY. THE GFS THERMAL FIELD

IS COLDER THAN THE UKMET OR CAN GGEM (HI RES ECMWF NOT VIEWABLE IN

TIME). BUT TO A CERTAIN EXTENT, IT DEPENDS UPON WHERE THE

DEFORMATION BAND ESTABLISHES ITSELF AS DYNAMIC COOLING WOULD CHANGE

THE RAIN TO SNOW REGARDLESS OF LOCATION. PAY ONE NOW OR PAY ONE

LATER, WE SUPPOSE IF THE LOW WOULD TREND FARTHER TO THE WEST, THIS

WOULD INCREASE THE HYDRO CONCERNS PARTICULARLY IN NJ AS EVENT TOTAL

QPF BY THE GFS/CAN GGEM AND UKMET ARE AVERAGING 1.5 TO 2.5 INCHES.

THE SYSTEM SHOULD BE EXITING OUR AREA AS FRIDAY CONTINUES AND ONCE

THE INTENSITY IS LOST, PRECIPITATION COULD GO BACK TO RAIN. BECAUSE

OF MARGINAL TEMPERATURES THIS HAS THE POTENTIAL TO BE A HEAVY WET

SNOW EVENT, NOT EXACTLY A UTILITY`S DREAM. WE LOADED IN SOME

CONSERVATIVE SNOW AMOUNTS IN THE GRIDS FOR NOW, BUT THIS SHOULD BE

VIEWED AS A VERY FIRST GUESS WITH REVISIONS TO FOLLOW. BROUGHT MIN

TEMPS CLOSER TO FREEZING FASTER OVERNIGHT BECAUSE OF ANTICIPATED

MIXING OR CHANGEOVER AND WITH SNOW PROBABLE ON THE GROUND IN PARTS

OF OUR CWA, WENT BELOW MEX MOS FOR MAX TEMPS.

 

 

This is a pretty broad forcast from Delaware to upstate PA. Alot of the cosmic tumblers in the universe will really need to come together for this to really be great, but it could definetly be something. The 1.5 to 2.5 numbers they are using are liquid, not inches of snow.

It is looking like a mixed bag for PA... Rain/Snow transitioning all to snow... Friday night at Boulder or CB may be the money shots... Great call on going north Moe... There is a ton of moisture with this system, so I wouldn't assume that it will be dry snow anywhere, but the farther north you go the lighter it should get (within reason). Looks like anywhere from the Skillz all the way to JP and SB will be winners... Have fun out there...
