AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
313 PM EDT WED APR 22 2015
.SYNOPSIS...
A COLD FRONT WILL MOVE ACROSS THE REGION THIS EVENING. LOW PRESSURE
WILL THEN MEANDER ABOUT NORTHERN NEW ENGLAND THROUGH EARLY NEXT
WEEK. WEAK HIGH PRESSURE THEN BUILDS IN FOR WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
A CLOSED LOW WILL REMAIN OVER CANADA THROUGH THE SHORT TERM. AS
THE LOW ROTATES...A COLD FRONT ASSOCIATED WITH IT WILL MOVE ACROSS
THE REGION THIS EVENING. SHOWERS AND EMBEDDED THUNDERSTORMS WILL
MOVE ACROSS THE REGION...EXITING THE REGION AROUND 00-02Z. THE
MAIN THREAT WITH ANY STORMS WILL BE BRIEF HEAVY DOWNPOURS...STRONG
GUSTY WINDS AND SMALL HAIL. WIND GUSTS UP TO 50 MPH HAVE ALREADY
BEEN OBSERVED WITH THE FRONT AS IT MOVED THROUGH CENTRAL AND
EASTERN PA.
ONCE THE FRONT MOVES EAST OF THE REGION...EXPECT MOSTLY DRY
CONDITIONS. THERE MAY HOWEVER STILL BE A FEW LEFT OVER PASSING
SHOWERS BEHIND THE FRONT.
OVERNIGHT LOWS WILL FALL INTO THE UPPER 30S TO LOWER 40S. FOLLOWED A
MAV/MET BLEND FOR LOWS TONIGHT.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THE CLOSED LOW REMAIN NORTH OF THE REGION THROUGH THE SHORT TERM.
ANOTHER STRONG VORT MAX AND SHORT WAVE WILL ROTATE AROUND THE LOW ON
THURSDAY. THIS WILL RESULT IN THE POTENTIAL FOR ANOTHER ROUND OF
SHOWERS THURSDAY AFTERNOON. THE BEST DYNAMICS WILL REMAIN NORTH OF
THE CWA...SO EXPECTING THE BEST CHANCES FOR ANY PRECIPITATION TO
OCCUR ACROSS THE LOWER HUDSON VALLEY AND CONNECTICUT. HIGHS ON
THURSDAY WILL BE COOLER WITH HIGHS IN THE LOWER AND MIDDLE 50S.
THURSDAY NIGHT WILL REMAIN DRY WITH A WESTERLY FLOW IN PLACE.
TEMPERATURES WILL BE CHILLY AS LOWS FALL INTO THE UPPER 20S AND
LOWER TO MIDDLE 30S. WITH THE COLD TEMPERATURES...EXPECT A DECENT
CHANCE FOR FROST/FREEZE HEADLINES. THE DEVELOPMENT FOR FROST HOWEVER
MAY BE HARD TO GET IF WINDS STAY UP AROUND 5-10 MPH.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
CLOSED UPPER LOW MEANDERS INVOF MAINE ON FRIDAY...AND SLOWLY SHIFTS
EAST ON SATURDAY. BOTH DAYS WILL BE FAIRLY SIMILAR...BUT FRIDAY
PROBABLY FEATURES MORE AFTERNOON CLOUDINESS WITH MORE OF A CYCLONIC
FLOW ALOFT AND MORE MID LEVEL MOISTURE PRESENT. A SHORTWAVE IS ALSO
PROGGED TO PASS THROUGH FRIDAY AFTERNOON/EVENING...BUT DEWPOINTS
WILL BE LOW WITH A DOWNSLOPE FLOW HELPING TO DRY THINGS OUT. MAYBE A
SPRINKLE OR TWO...BUT WILL MAINTAIN A DRY FORECAST IN THE GRIDS FOR
NOW. BOTH DAYS WILL FEATURE BELOW-NORMAL TEMPERATURES...BUT SATURDAY
IS SHAPING UP TO BE THE WARMER OF THE TWO.
FOR SUNDAY...MODELS HAVE THE UPPER LOW RETROGRADING TOWARDS MAINE.
THIS PROBABLY SUPPRESSES SURFACE LOW PRESSURE OVER THE MID ATLANTIC
AND KEEPS ANY ASSOCIATED RAINFALL TO OUR SOUTH. TEMPS ALOFT RISE A
LITTLE...SO HIGH TEMPS SHOULD GET CLOSER TO NORMAL...BUT PROBABLY
FALLING SHORT IN MOST CASES.
THE UPPER LOW THEN BEGINS TO SHIFT SOUTH...CLOSER TO THE TRI STATE
AREA. MOISTURE AND LIFT INCREASE...SO HAVE SLIGHT CHC OF SHOWERS FOR
THE AFTERNOON WHEN INSTABILITY INCREASES. A SURFACE REFLECTION IN
THE FORM OF THE TROUGH SHARPENS AND GRADUALLY SHIFTS THROUGH THE
REGION MONDAY NIGHT THROUGH TUESDAY. WILL GO WITH JUST SLIGHT CHC OF
SHOWERS FOR NOW DURING THIS PERIOD...BUT THIS MIGHT EVENTUALLY NEED
TO BE BUMPED UP IF MODEL TRENDS HOLD.
WEAK RIDGING OCCURS ON WEDNESDAY AS THE UPPER LOW FINALLY HEADS OUT
TO SEA. THIS PROBABLY KEEPS ANY CHANCE OF RAIN TO OUR SOUTH AS LOW
PRESSURE TRACKS ACROSS THE SOUTHEAST STATES. MODELS HAVE THIS SYSTEM
EVENTUALLY LIFTING NE AS IT REACHES THE EASTERN SEABOARD...SO THIS
COULD AFFECT US LATER IN THE WEEK.
HIGH TEMPERATURES MONDAY THROUGH WEDNESDAY SLIGHTLY BELOW NORMALS.
