AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
153 PM EDT TUE MAR 17 2015
.SYNOPSIS...
DEEPENING LOW PRESSURE EAST OF NEW ENGLAND THIS AFTERNOON WILL
LIFT UP INTO THE CANADIAN MARITIMES...WHILE HIGH PRESSURE BUILDS
EAST FROM THE UPPER MIDWEST OVER THE NEXT SEVERAL DAYS. A COASTAL
LOW PRESSURE SYSTEM MAY IMPACT THE AREA FRIDAY INTO FRIDAY
NIGHT...FOLLOWED BY A COLD FRONTAL PASSAGE LATE SATURDAY. HIGH
PRESSURE BUILDS TOWARDS THE REGION FROM THE GREAT LAKES SUNDAY
INTO MONDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
COLD FRONT HAS CLEARED EASTERN LI/SE CT WITH A STRONG NW FLOW IN
ITS WAKE. GUSTS UP 45 MPH IN A FEW SPOTS FOLLOWING FRONTAL
PASSAGE. IRONICALLY...AS THE FLOW BECAME NW MOST LOCATIONS ALONG
THE COAST SHOT UP 10 TO 15 DEGREES WITH READINGS IN THE MID TO
UPPER 50S. WITH WATER TEMPS IN THE 30S...THE ONSHORE FLOW WAS
COOLER THAN THE AIR BEHIND THE FRONT. THIS WILL CHANGE TOWARD
EVENING AS MUCH COLDER AIR WORKS IN.
NW WINDS WILL REMAIN STRONG FOR THE REMAINDER OF THIS AFT DUE TO
THE COMBINATION OF STRONG CAA AND A TIGHTENING PRES GRADIENT
BETWEEN A RAPIDLY INTENSIFYING OFFSHORE LOW TO THE NE AND STRONG
CANADIAN HIGH PRES BUILDING TO THE W. WINDS ARE EXPECTED TO RANGE
FROM 15 TO 25 MPH WITH GUSTS 40 TO 45 MPH.
HIGHS HAVE BEEN MET WITH MOST LOCATIONS HAVING TOPPED OUT IN THE
50S. TEMPS WILL GRADUALLY FALL.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
TIGHT PRES GRADIENT REMAINS ACROSS THE REGION INTO WED BEFORE
FINALLY STARTING TO RELAX DURING WED AFTN. GUSTY NW WINDS WILL
CONTINUE DURING THIS TIME...ALTHOUGH THE STRONGEST WINDS WILL HAVE
PASSED.
DEEP NW FLOW WILL SEND WEAK SHORTWAVES THROUGH THE FLOW AS WELL.
MODELS ARE HINTING AT SCT SHOWER ACTIVITY TO THE N AND W OF THE
AREA...BUT NOT CONVINCED IT WILL MAKE IT OVER THE MOUNTAINS DUE TO
DOWNSLOPING. THEREFORE HAVE INCREASED CLOUDS...BUT HAVE KEPT THE

FAST APPROACH ON FRIDAY SPAWNING A LOW PRESSURE OFF THE MIDDLE
ATLANTIC COAST. THERE STILL IS A FAIRLY LARGE SPREAD AMONG THE
MEDIUM RANGE OPERATIONAL MODELS AND ENSEMBLES ON THE TIMING AND
AMPLITUDE OF THIS ENERGY. THIS LEADS TO TRACK AND STRENGTH
DIFFERENCES WITH THE DEVELOPING LOW PRESSURE. THE GFS AND ITS
ENSEMBLES CONTINUE TO BE FURTHEST SOUTH WITH THE LOW KEEPING THE
HEAVIEST PRECIPITATION SOUTH OF LONG ISLAND. THE EURO AND CMC ARE
FURTHER NORTH WITH THE LOW BRINGING MORE SUBSTANTIAL PRECIPITATION
FRIDAY INTO AT LEAST THE FIRST PART OF FRIDAY NIGHT. WITH THERE
STILL REMAINING A FAIRLY LARGE SPREAD BEING DEPICTED BY THE 00Z
MODELS...HAVE OPTED TO STAY WITH HIGH CHANCE POPS FOR THIS FORECAST
PACKAGE.

SOME MID LEVEL WARMTH IS ALSO POSSIBLE FURTHER COMPLICATING THE
PTYPE...HAVE MAINTAINED CONSISTENT WORDING FROM PREVIOUS FORECAST OF
RAIN AND SNOW DUE TO CONTINUED UNCERTAINTY IN THERMAL PROFILES.
