AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
1058 AM EDT MON SEP 2 2013
.SYNOPSIS...
A TROUGH OF LOW PRESSURE OVER THE AREA TODAY...WILL GIVE WAY TO A
COLD FRONT WHICH CROSSES THE TRI-STATE FROM TONIGHT INTO TUESDAY. HIGH
PRESSURE BUILDS IN TUESDAY NIGHT THROUGH WEDNESDAY NIGHT AS
ANOTHER COLD FRONT ADVANCES FROM THE NORTH. THIS FRONT WILL PUSH
SOUTH OF THE AREA ON THURSDAY WITH ANOTHER AREA OF HIGH PRESSURE
BUILDING IN FROM THE GREAT LAKES. THIS HIGH WILL TRACK TO THE MID
ATLANTIC COAST BY THE END OF THE WORK WEEK AS A WARM FRONT PASSES
TO OUR NORTH. YET ANOTHER COLD FRONT PUSHES THROUGH FOR THE
UPCOMING WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
QUICK UPDATE TO ADJUST POPS BASED ON RADAR AND LATEST MESOSCALE
MODELS.
A TEMPORARY LULL IN OVERALL PRECIP NOTED THIS MORNING...BUT NEXT
SHORTWAVE TRIGGERING SHOWERS/TSTMS TO THE SOUTH AND THIS ACTIVITY
WILL NEED TO BE WATCHED. EXPECT SHOWER/TSTM COVERAGE TO GROW THIS
AFTERNOON. GIVEN VERY MOIST LOW-MID LEVELS LOCALLY HEAVY RAINFALL
IS POSSIBLE WITH ANY STRONGER CONVECTION. REFER TO THE HYDROLOGY
SECTION OF THE AFD FOR DETAILS.
BASED ON THIS...HIGHS SHOULD RUN A FEW DEGREES ABOVE NORMAL.
HOWEVER...AMOUNT OF CLOUD COVER WILL ULTIMATELY DETERMINE HOW
HIGH TEMPS GET THIS AFTERNOON.
THERE IS A MODERATE RISK OF RIP CURRENTS AT THE ATLANTIC OCEAN
BEACHES INTO THIS EVENING.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
CLOSED LOW TRACKS FROM SE ONTARIO INTO SE QUEBEC FROM THIS EVENING
THROUGH TUESDAY AS IT SLOWLY OPENS. SHORTWAVES COMING AROUND THE
BASE OF THE LOW/DEVELOPING TROUGH AND FORCING AHEAD OF A PASSING
COULD FRONT SHOULD PRODUCE SCT CONVECTION. LATEST GUIDANCE
SHOWING BEST CHANCE THIS EVENING...WITH A LULL OVERNIGHT...THEN
ANOTHER ROUND OF CONVECTION TUESDAY MORNING/EARLY AFTERNOON
IMMEDIATELY AHEAD OF THE FRONT. BEST DYNAMICS IS FORECAST TO PASS
TO OUR NORTH WITH THE OPENING UPPER LOW - HENCE RESTRICTING POPS
TO CHANCE TONIGHT...THEN LIKELY ON TUESDAY WITH THE COLD FRONT.
SEE HYDROLOGY SECTION OF AFD FOR DETAILS ON EXPECTED RAINFALL
AMOUNTS AND POSSIBLE IMPACTS.
FOR LOWS TONIGHT USED A BLEND OF MAV/MET GUIDANCE WITH NAM 2-METER
TEMPERATURES - WITH VALES EXPECTED TO BE AROUND 5 DEGREES ABOVE
NORMAL. HIGHS TUESDAY SHOULD BE A FEW DEGREES ABOVE NORMAL - BASED
ON A BLEND OF MIXING DOWN FROM 900 HPA AND 875 HPA WELL
INLAND...WITH NAM 2-METER TEMPERATURES AND A BLEND OF MAV/MET
GUIDANCE.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
THE LONG TERM PERIOD WILL START WITH A LONGWAVE TROUGH DOMINATING
THE NORTHEAST WITH LARGE RIDGE OVER THE CENTRAL AND SOUTHERN PART OF
THE COUNTRY AND A CUTOFF LOW PRESSURE SYSTEM OFF THE PAC NW. THE NE
TROUGH WILL REMAIN IN PLACE THROUGH THE FORECAST PERIOD WITH A
SERIES OF SHORTWAVES MOVING THROUGH THE FLOW.
MODELS ARE IS GOOD AGREEMENT THROUGH THE END OF THE WEEK...WITH THE
EXCEPTION OF THE CMC WHICH DEVELOPS THE TROPICAL WAVE CURRENTLY NEAR
THE LESSER ANTILLES AND CURVES IT OVER 30N 70W ON SAT...WITH JUST
SOME SLIGHT TIMING DIFFERENCES WITH A COLD FROPA NEXT WEEKEND.
DESPITE A FAIRLY ACTIVE NORTHERN STREAM...FAIRLY BENIGN WEATHER IS
EXPECTED. AT THE SFC...HIGH PRES BUILDS IN ON WED WITH A MUCH MORE
COMFORTABLE AIRMASS BEHIND THE COLD FRONT. A WEAK COLD FRONT
APPROACHING FROM THE NORTH MAY TRIGGER SOME SHOWERS ON THU WITH
ANOTHER AREA OF HIGH PRES BUILDING IN FROM THE GREAT LAKES BEHIND
IT. DRY WEATHER WILL PREVAIL THROUGH THE END OF THE WEEK...ALTHOUGH
A SW FLOW WILL DEVELOP AS THE HIGH SINKS TO THE S. THIS WILL RESULT
IN INCREASING HUMIDITY LEVELS ONCE AGAIN BEFORE YET ANOTHER COLD
FRONT PASSES THROUGH NEXT WEEKEND.
TEMPS WILL REMAIN NEAR TO SLIGHTLY BELOW SEASONABLE LEVELS THROUGH
THE PERIOD.
&&
.AVIATION /15Z MONDAY THROUGH FRIDAY/...
A COLD FRONT ACROSS THE MIDWEST WILL SLOWLY TRACK TOWARD THE AREA
THROUGH THE FORECAST PERIOD.
CONDITIONS VARY MAINLY FROM MVFR TO IFR...WITH LOCALLY HIGHER OR LOWER
CONDITIONS. NOT EXPECTING MUCH IMPROVEMENT TODAY...HOWEVER BRIEF
BREAKS TO VFR CAN NOT BE RULED OUT.
SCATTERED SHOWER AND THUNDERSTORM ACTIVITY THIS MORNING WILL
INCREASE THIS AFTERNOON. THUNDERSTORMS ARE FORECAST TO REMAIN
SCATTERED THIS AFTERNOON. TRYING TO TIME ANY SHOWERS AT ANY ONE
TERMINAL AT THIS POINT SEEMS RATHER DIFFICULT. THEREFORE...WILL GO
WITH VICINITY SHOWERS IN THE TAFS AND AS CONFIDENCE GROWS WILL AMEND
WITH MORE SPECIFIC TIMING.
WINDS WILL BE GENERALLY 10 KTS OR LESS AND FROM A SOUTH TO
SOUTHEAST DIRECTION THROUGH THE DAY WITH A MORE SW-W TURN LATER
TONIGHT WITH THE APPROACH OF THE COLD FRONT. CONFIDENCE MODERATE
WITH WIND FORECAST AND LOW WITH CATEGORY FORECAST.
