AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
211 PM EDT SUN APR 17 2016
.SYNOPSIS...
HIGH PRESSURE WILL DOMINATE THE WEATHER THROUGH MONDAY. A COLD FRONT
PASSES THROUGH MONDAY NIGHT INTO TUESDAY MORNING. HIGH PRESSURE
BUILDS IN TUESDAY AND REMAINS IN CONTROL THROUGH THURSDAY. A WEAK
FRONTAL SYSTEM MOVES THROUGH FRIDAY INTO SATURDAY.
&&
.NEAR TERM /THROUGH TONIGHT/...
OMEGA BLOCK PATTERN CONTINUES TODAY WITH DEEP RIDGING ALOFT OVER
THE EASTERN STATES. MUCH WEAKER PRESSURE GRADIENT PRESENT COMPARED
TO SATURDAY AS THE SURFACE HIGH MOVES OVER THE REGION AND THE
OFFSHORE LOW MOVES FURTHER OUT TO SEA.
AIR MASS MODERATES SEVERAL DEGREES WITH WARMER AIR ALOFT COMPARED TO
SATURDAY. THIS WILL TRANSLATE TO HIGHS REACHING THE UPPER 60S AND
LOWER 70S AWAY FROM THE IMMEDIATE COAST. WITH WEAK FLOW AND LESS
MIXING TODAY...SEA BREEZE DEVELOPMENT IS LIKELY NEAR THE COAST. THIS
SHOULD HELP CAP TEMPERATURES IN THE LOWER AND MIDDLE 60S. WENT A FEW
DEGREES ABOVE STATISTICAL GUIDANCE...ESPECIALLY AWAY FROM THE COAST.
CLEAR CONDITIONS TONIGHT WITH TEMPERATURES FALLING INTO THE UPPER
30S AND LOWER 40S INLAND AND FOR MUCH OF THE LONG ISLAND PINE
BARRENS. THE MIDDLE AND UPPER 40S WILL BE COMMON ELSEWHERE WITH
READINGS ONLY IN THE 50S ACROSS THE CITY.
&&
.SHORT TERM /MONDAY THROUGH TUESDAY/...
RIDGING ALOFT BREAKS DOWN ON MONDAY AS AN UPPER LOW MOVES ACROSS
SOUTHEAST CANADA. SURFACE HIGH ALSO SHIFTS SOUTH AND WEST OF THE
AREA. THIS WILL ALLOW FOR MORE OF A WESTERLY FLOW AT THE SURFACE AND
EVEN WARMER CONDITIONS THAN SUNDAY. A COLD FRONT WILL SLOWLY SINK
SOUTHWARD AS UPPER ENERGY DIVES SE TOWARDS NEW ENGLAND ON THE
BACKSIDE OF THE UPPER LOW ACROSS SE CANADA. JUST A SLIGHT INCREASE
IN HIGH CLOUDS DURING THE DAY AS THE ATMOSPHERE REMAINS DRY. HIGHS
WILL BE IN THE LOWER AND MIDDLE 70S AWAY FROM THE COAST...AND UPPER
60S AND LOWER 70S NEAR THE COAST.
A WEAK WAVE OF LOW PRESSURE DEVELOPS OVER NEW ENGLAND AHEAD OF THE
UPPER ENERGY MONDAY NIGHT. THIS WILL HELP PUSH THE COLD FRONT
THROUGH EARLY TUESDAY MORNING. THERE IS GOOD AGREEMENT AMONG THE
MODELS WITH THE BEST LIFT AND MOISTURE PASSING TO THE NORTHEAST AND
THIS MAKES SENSE GIVEN THAT THE ENERGY IS PROGGED TO PASS ACROSS
EASTERN NEW ENGLAND. THE 12Z ECMWF WAS MOST AGGRESSIVE WITH QPF
ACROSS EASTERN SECTIONS...BUT HAS SHIFTED TO THIS TO THE NE OF THE
AREA WITH THE 00Z RUN. THIS IS MORE IN LINE WITH THE REST OF THE
GUIDANCE. WILL CARRY CHANCE POPS ACROSS SE CT AND FAR EASTERN LONG
ISLAND EARLY TUESDAY MORNING.
THE LOW WILL DEEPEN AS IT RAPIDLY MOVES WELL OFFSHORE ON TUESDAY.
HIGH PRESSURE BUILDS SOUTH INTO THE AREA WITH AN INCREASING PRESSURE
GRADIENT. THIS COULD LEAD TO A BREEZY NW FLOW DURING THE AFTERNOON.
TEMPERATURES WILL ALSO BE CLOSER TO SEASONAL NORMALS THAN COMPARED
TO MONDAY.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
HIGH PRESSURE WITH WEAK UPPER RIDGING BUILDS IN FOR TUESDAY NIGHT
INTO THURSDAY. THE WEAKENING OF THE RIDGE AND TIMING AND
PLACEMENT OF THE NEXT SHORTWAVE AND LOW WILL BE DEPENDENT ON THE
OPENING UP AND MOVEMENT OF THE CUTOFF LOW ACROSS THE INTERMOUNTAIN
SOUTHWEST. WITH THE UNCERTAINTIES HAVE LEANED TOWARD THE WPC AND
ECMWF GUIDANCE...ESPECIALLY THURSDAY NIGHT INTO SATURDAY.
&&
.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
HIGH PRESSURE REMAINS IN CONTROL THROUGH MONDAY.

CONTINUED ESE SWELL FROM OFFSHORE LOW PRESSURE. SEAS SHOULD
GRADUALLY SUBSIDE TONIGHT INTO MONDAY.
OCEAN SEAS MAY SUBSIDE BELOW SCA LEVELS ON MONDAY WITH THE
REMAINDER OF THE FORECAST WATERS BELOW SCA CRITERIA. A COLD FRONT
PASSES ACROSS THE WATERS TUESDAY MORNING. A STRENGTHENING AND
GUSTY NORTHERLY FLOW BEHIND THE FRONT COULD BUILD SEAS ON THE
OCEAN TO SCA LEVELS. GUSTS MAY ALSO APPROACH 20 TO 25 KT. HIGH
PRESSURE BUILDS TUESDAY NIGHT WITH WINDS AND SEAS SUBSIDING BELOW
SMALL CRAFT LEVELS.
SUB SMALL CRAFT CONDITIONS ARE FORECAST FROM LATE TUESDAY INTO LATE
THURSDAY AS HIGH PRESSURE MOVES THROUGH THE REGION. THEN WITH AN
