AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
446 AM EDT WED APR 16 2014

.SYNOPSIS...
HIGH PRESSURE BUILDS OVER THE REGION TODAY AND DRIFTS NORTHEAST
TONIGHT AND THURSDAY. HIGH PRESSURE REMAINS OVER THE NORTHEAST
FRIDAY INTO THE WEEKEND AS MULTIPLE LOW PRESSURE AREAS RIDE A
STALLED FRONT TO THE EAST. THE HIGH FINALLY PUSHES OFF TO THE
EAST BEGINNING OF NEXT WEEK WITH LOW PRESSURE RETURNING FOR MID
WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A FREEZE WARNING REMAINS IN EFFECT EARLY THIS MORNING AS COLD AIR
MOVES IN BEHIND A STRONG COLD FRONT AND TEMPERATURES FALL BELOW
FREEZING. RECORD LOWS ARE POSSIBLE THIS MORNING. SEE CLIMATE
SECTION BELOW. THE LAST OF THE WINTRY MIX OF PRECIPITATION WAS
MOVING OUT OF NEW LONDON COUNTY AND THE TWIN FORKS AT 08Z.

RIDGE BUILDS INTO THE REGION THROUGH TODAY. GUSTY NORTHWEST FLOW
WILL BE DIMINISHING THROUGH THIS MORNING AND INTO EARLY AFTERNOON
AS COLD ADVECTION WEAKENS AND WINDS ALOFT DIMINISH...WITH MIXING
TO AROUND 900 MB. TEMPERATURES WILL BE WELL BELOW NORMAL WITH
HIGHS IN THE 40S. NORMAL HIGHS ARE AROUND 60.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
RIDGE REMAINS ACROSS THE REGION TONIGHT INTO THURSDAY AS SURFACE
HIGH REMAINS TO THE NORTHEAST AND RIDGES DOWN ALONG THE EASTERN
SLOPES OF THE APPALACHIANS. THE COLD AIR MASS WILL REMAIN IN PLACE
TONIGHT INTO THURSDAY. TEMPERATURES WILL AGAIN APPROACH OF FALL
BELOW FREEZING ACROSS THE AREA. NO RECORDS ARE EXPECTED TO BE
BROKEN TONIGHT UNLESS TEMPERATURES FALL LOWER THAN FORECAST AS
SKIES WILL BE CLEAR AND WINDS WILL INITIALLY BE LIGHT IN THE
EVENING. THEN WITH THE HIGH BUILDING TO THE NORTHEAST WINDS WILL
INCREASE FROM THE NORTHEAST BRINGING IN COOLER NORTHERN ATLANTIC
AIR LATER TONIGHT INTO THURSDAY. THURSDAYS HIGHS WILL ONLY BE A
COUPLE OF DEGREES HIGHER THAN TODAYS HIGHS.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
INITIALLY DRY WEATHER THURSDAY NIGHT AS THE CENTER OF THE SURFACE 
HIGH PUSHES NORTH AND EAST WHILE THE AREA REMAINS UNDER BROAD 
RIDGING. GLOBAL MODELS SUGGEST WEAK LOW PRESSURE DEVELOPMENT ALONG A 
STALLED FRONT OFFSHORE THAT COULD BRING LIGHT PCPN INTO THE AREA BY 
FRIDAY MORNING...THEN SLOWLY SPREADING TO THE NORTH FRI NIGHT INTO 
SAT. 00Z GFS A BIT MORE PRONOUNCED IN THE DEVELOPMENT OF THE LOW AND 
THE RESULTING PCPN WITH THE SUGGESTION OF INTERACTION BETWEEN A 
SOUTHERN STREAM SHORTWAVE WITH THE NORTHERN STREAM TROUGH/CLOSED 
LOW. ALL OTHER MODELS KEEP A DISTINCT SEPARATION BETWEEN THE TWO SO 
WENT AHEAD AND MAINTAINED THE SLIGHT CHC/CHC POPS FOR NOW WITH 
UNCERTAINTY ON JUST HOW WIDESPREAD THE PCPN OCCURS. AN APPROACHING 
FRONT SAT COULD TRIGGER SCT RAIN SHOWERS AS THE UPPER LEVEL TROUGH 
SWINGS THROUGH. THINGS THEN DRY OUT FOR SAT NIGHT-SUNDAY WITH ZONAL FLOW 
SETTING UP ALOFT AND HIGH PRESSURE BUILDING SOUTH INTO THE 
NORTHEAST.   

SOME MODEL DISCREPANCIES IN THE HANDLING OF THE NEXT LOW PRESSURE 
SYSTEM NEXT WEEK. 00Z GFS LINGERS THE HIGH OVER THE NORTHEAST THEN 
BRINGS A WEAK FRONT IN FROM THE WEST WHILE ECMWF AND CMC BOTH 
DEVELOP A DECENT AREA OF LOW PRESSURE OFF COASTAL FLORIDA AND TRACK 
TO THE NORTH ALONG A STALLED FRONT. FLOW ALOFT SUGGESTS MORE OF A 
GFS SOLUTION IN THIS CASE...SO SIDED MORE TO A GFS/WPC 
BLEND...BRINGING POPS IN MONDAY NIGHT AND KEEPING THEM IN PLACE 
THROUGH TUESDAY WITH THE FRONT REMAINING IN THE VICINITY AND 
MULTIPLE SHORTWAVES RIDING THE FLOW ALOFT. 

COOLER WEATHER IN STORE FOR THE TRI STATE AREA THURS NIGHT/FRI AS 
THE POSITIONING OF THE HIGH KEEPS A COOLER EASTERLY/NORTHEASTERLY 
FLOW DESPITE WAA ALOFT. HOWEVER...AS WINDS SHIFT FOR THE 
WEEKEND...EXPECT TEMPS TO WARM BACK TO NEAR NORMAL. OVERALL...TEMPS 
EXPECTED TO REMAIN WARM ENOUGH WITH TIMING OF PCPN TO KEEP PCPN IN 
THE FORM OF RAIN. THURS NIGHT WILL BE THE COLDEST NIGHT IN THE 
EXTENDED...THOUGH CURRENTLY NOT EXPECTING FROST/FREEZE ISSUES IN 
AREAS CURRENTLY IN THE GROWING SEASON.

&&
