AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
1049 AM EDT THU MAY 22 2014
.SYNOPSIS...
A TROUGH OF LOW PRESSURE WILL REMAIN IN THE VICINITY THROUGH THE
END OF THE WEEK. A SERIES OF DISTURBANCES IN THE NORTHWEST FLOW
ALOFT WILL THEN MOVE ACROSS THE REGION THIS WEEKEND. HIGH PRESSURE
WILL PASS TO THE SOUTH ON MONDAY WITH A WEAK FRONTAL SYSTEM
POSSIBLY IMPACTING THE AREA ON TUESDAY. HIGH PRESSURE FOLLOWS FOR
THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
WEAK LOW PRESSURE OVER CENTRAL NY WITH UPPER LEVEL SHORTWAVE ALOFT
DRIVING CONVECTION AHEAD OF IT. SEVERE POTENTIAL WITH THIS FEATURE
APPEARS LOW. SMALL HAIL POSSIBLE THOUGH. EXPECT ACTIVITY TO REACH
THE NORTHERN PORTION OF THE NY METRO AROUND 11 AM.
BREAKS IN CLOUD COVER THIS AFTERNOON FOLLOWING THE LATE MORNING
CONVECTION RESULTS IN INCREASE INSTABILITY. THUS STILL EXPECTING
ANOTHER ROUND OF CONVECTION. ALTHOUGH BULK SHEAR WILL BE AROUND
40KT ALL DAY WITH A VEERING PROFILE...CAPE WILL BE LOW IN THE
MORNING. ISOLATED TO SCATTERED THUNDERSTORMS THEREFORE
ANTICIPATED. CHANCES FOR MORE WIDESPREAD AND POTENTIALLY STRONG
THUNDERSTORMS INCREASE IN THE AFTERNOON OVER THE WESTERN HALF OF
THE CWA AS CAPE INCREASES AND THE LEFT FRONT REGION OF A JET
STREAK ALOFT SHIFTS INTO THE AREA. WITH FORECAST CAPE OF 500-1000
J/KG IN THE HAIL GROWTH REGION OVER THE WESTERN FRINGE OF THE
CWA...LARGE HAIL ALONG WITH STRONG WIND GUSTS ARE POSSIBLE. WILL
KEEP THE MENTION OF THIS POTENTIAL IN THE HWO. PLEASE SEE THE
HYDROLOGY SECTION BELOW FOR POTENTIAL RAINFALL IMPACTS.
CLOUD COVER AND ONSHORE FLOW WILL RESULT IN HIGH TEMPS A LITTLE
BELOW NORMAL FOR THE MOST PART. A BLEND OF MAV/NAM MOS REFLECTS THIS.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
OCCLUDED FRONT PUSHES THROUGH PART OF THE CWA TONIGHT BEFORE
STALLING OVER THE EASTERN ZONES LATE AT NIGHT INTO FRIDAY MORNING.
THEREFORE EXPECTING AN EASTWARD SHIFT OF THE MOST DENSE SHOWER
COVERAGE AS THIS WILL BE THE AREA OF BEST LIFT AND MOISTURE
CONVERGENCE. THUNDERSTORMS WILL STILL BE POSSIBLE...BUT BECAUSE THE
CAPE BECOMES MORE ELEVATED IN NATURE...DIMINISHING CHANCES OF STRONG
CONVECTION.
AN INVERTED TROUGH...WHICH WAS PREVIOUSLY THE OCCLUDED
FRONT...DRIFTS BACK WESTWARD DURING THE DAY FRIDAY AS THE ASSOCIATED
LOW PRESSURE CENTER TO THE SE BEGINS TO STRENGTHEN. MODEL
DIFFERENCES MAKE THE TROUGH'S PLACEMENT BY THE END OF THE DAY
UNCERTAIN...BUT PROBABLY FAVORING SOMEWHERE IN THE WESTERN HALF OF
THE CWA. WITH AN APPROACHING STRONG MID LEVEL SHORTWAVE AND
INCREASING CAPE LATE IN THE DAY...EXPECTING SHOWERS TO BECOME MORE
NUMEROUS HERE. WITH WEAK SHEAR AND MOST OF THE CAPE ELEVATED...THE
POTENTIAL FOR STRONG THUNDERSTORMS WILL BE LIMITED.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
LARGE SCALE RIDGING WILL WORK EAST FROM THE MID SECTION OF THE
COUNTRY THROUGH NEXT WEEK...WHILE THE MEAN TROUGH ALONG THE NEW
ENGLAND COAST STUBBORNLY PRESSES EASTWARD THROUGH THE WEEKEND. THE
LATTER OF WHICH WILL RESULT IN MAINLY SCT DIURNAL CONVECTION SAT AND
SUN. CONVECTION NOT EXPECTED TO BE ALL THAT STRONG WITH A WEAK
SHEAR...LOW CAPE ENVIRONMENT. LOW WET-BULB ZERO HEIGHTS MAY RESULT
IN SOME SMALL HAIL WITH THE STRONGEST ACTIVITY. THERE ARE SOME MODEL
DISCREPANCIES WITH MAGNITUDE AND TIMING OF THE SHORT WAVE ENERGY
RIDING OVER TOP THE RIDGE IN CENTRAL CANADA AND INTO THE NW FLOW
ACROSS NEW ENGLAND. THE GFS IS STRONGER AND MORE SUBSTANTIAL WITH A
AN UPPER LOW PASSING TO THE EAST SUN NIGHT INTO MON...WHILE THE NAM
AND ECMWF ARE WEAKER AND FASTER. THIS WILL NEED TO BE WATCHED IN
SUBSEQUENT RUNS...BUT IN ALL SOLUTIONS THE FORECAST AREA LIES TO
THE WEST OF THE TROUGH AXIS WITH A DRYING MOISTURE PROFILE SUN INTO
MON.
HIGH PRESSURE PASSES TO THE SOUTH ON MON WITH ANOTHER SHORT
WAVE/WEAKENING FRONTAL SYSTEM POSSIBLY IMPACTING THE AREA WITH SCT
CONVECTION TUE INTO WED. ONCE AGAIN THERE ARE SOME TIMING AND
MAGNITUDE ISSUES AS THE UPPER SHORT WAVE RIDES OVER TOP THE RIDGE
AND INTO THE NE. BY MID WEEK...THE UPPER PATTERN FEATURES A REX
BLOCK WITH A CUTOFF LOW OVER THE MID MS VALLEY TRAPPED UNDER THE
BROAD...UPPER RIDGE OVER THE LOWER 48...WITH BOOKEND TROUGHS OVER THE
PAC NW AND OFF THE NEW ENGLAND COAST.
TEMPS DURING THIS TIME WILL START OFF AT NEARLY SEASONABLE LEVELS ON
SAT...AND THEN GRADUALLY WARM THROUGH THE UPCOMING WEEK.
&&
.AVIATION /15Z THURSDAY THROUGH MONDAY/...
A TROUGH OF LOW PRESSURE WILL REMAIN OVER WESTERN PORTIONS OF THE
TRI-STATE...WITH WEAK WAVES OF LOW PRESSURE PASSING JUST TO THE
SOUTH OF LONG ISLAND...THROUGH TONIGHT.
EXPECT FIRST BATCH OF CONVECTION TO BE THROUGH CITY TERMINALS BY
16Z AND THROUGH EASTERN TERMINALS BY 18Z. NEXT ROUND OF CONVECTION
SHOULD DEVELOP AND BEGIN IMPACTING WESTERN TERMINALS BY AROUND
20-21Z...AND IMPACT AREA TERMINALS FROM W TO E INTO THE EARLY
EVENING.
VARIABLE CONDITIONS AT AREA TERMINALS FROM IFR TO VFR AS A RESULT.
MAINLY SE-ESE FLOW INTO THIS AFTERNOON...BACKING TO THE NE THEN N
TONIGHT OVER WESTERN TERMINALS. WINDS GENERALLY 10 KT OR LESS.
