AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
244 PM EDT THU APR 29 2010
.SYNOPSIS...
HIGH PRESSURE BOTH ALOFT AND AT THE SURFACE WILL BUILD EAST
THROUGH THE UPCOMING WEEKEND. A FRONTAL SYSTEM WILL APPROACH THE
AREA ON SUNDAY WITH A COLD FRONTAL PASSAGE FORECAST ON MONDAY.
WEAK HIGH PRESSURE FOLLOWS BEHIND THE FRONT FOR TUESDAY AND
WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
STRONG JET DRIVING THROUGH THE REGION THIS AFTERNOON. WIND GUST OF
49 KT JUST REPORTED AT KBDL SO WIND ADVISORY ISSUED FOR THE ERN
HALF OF THE CWA TIL 00Z.
SOME FAIR WEATHER CLOUDS ACROSS CT SPREADING SWWD INTO THE METRO
AS SHRTWV TRACKS THRU THE ERN ZONES. SUNNY TO MOSTLY SUNNY INTO
THIS EVENING.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
A DRY...WARM PATTERN SETTING UP THROUGH THE WEEKEND AS A HIGH
AMPLITUDE RIDGE ALOFT BUILDS ACROSS THE AREA. THIS WILL RESULT IN
INCREASINGLY WARMER DAYS...ESPECIALLY ACROSS THE INTERIOR WHERE
THERE WILL BE LESS OF A MARITIME INFLUENCE. HIGHS BY SAT WILL BE
IN THE 80S ACROSS THE INTERIOR....AND 70S AT THE COAST. THERE
SHOULD THOUGH BE ENOUGH OF A SW COMPONENT TO ALLOW EVEN COASTAL
AREAS TO HEAT UP IN THE MORNING PRIOR TO AFTERNOON SEABREEZE
DEVELOPMENT.
OVERNIGHT LOWS FRI MORNING WILL BE IN THE UPPER 30S ACROSS THE
INTERIOR...BUT WITH WEAK WARM ADVECTION AND A W/SW FLOW...NOT
EXPECTING WIDESPREAD FROST. THEREAFTER...LOWS WARM UP INTO THE
UPPER 50S AND LOWERS 60S BY SUN MORNING.
NO PCPN IS EXPECTED. EPISODES OF MID AND UPPER LEVEL WARM ADVECTION
WILL PRESENT SOME CLOUDS ON FRI...BUT THE THICKER OF THE CLOUDS
WILL COME SAT NIGHT AS THE RIDGE AXIS SLIPS EAST OF THE AREA. AT
THIS TIME...INSTABILITY SHOWERS ARE FORECAST TO STAY TO THE NW OF
THE AREA SAT AFT WITH WARM ADVECTION PCPN BYPASSING THE AREA SAT
NIGHT...ALSO TO THE NW.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
MODELS ARE CONVERGING ON THE TIMING OF A COLD FRONT PASSAGE ACROSS
THE AREA. BEST GUESS IS THAT IT MOVES THROUGH HERE LATE SUNDAY NIGHT
INTO MONDAY MORNING. SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED
AHEAD OF THIS FRONT WITH A PRE-FRONTAL TROUGH AND SUFFICIENT CAPE.
ALTHOUGH TEMPERATURES ALOFT ACTUALLY WARM UP FROM
SATURDAY...THINKING IS THAT WE'LL HAVE MORE CLOUD COVER. STILL THINK
WE'LL GET AT LEAST PARTLY SUNNY SKIES...BUT KEPT HIGHS IN THE UPPER
70S TO LOWER 80S. MORE SUNSHINE WOULD RESULT IN TEMPERATURES AT
LEAST 5 DEGREES HIGHER.
MODELS DIVERGE FROM THIS POINT. HAVE KEPT IN CHANCE TO SLIGHT CHANCE
POPS ON MONDAY TO ACCOUNT FOR THE POSSIBILITY THAT THE FRONT SLOWS
DOWN WHILE PASSING THROUGH. HIGH PRESSURE WOULD THEN BUILD BEHIND
THE FRONT FOR DRY WEATHER ON TUESDAY ALONG WITH TEMPS A LITTLE ABOVE
NORMAL. SLIGHT CHANCE POPS ON WEDNESDAY FOR THE POTENTIAL OF ANOTHER
DISTURBANCE MOVING THROUGH.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
VFR...UNLIMITED CIGS/VSBYS THROUGH FRIDAY.
SFC TROUGH MOVING THROUGH REGION THIS AFTERNOON...WITH WINDS
SHIFTING MORE WNW BEHIND IT TO A GENERAL 280-290 DEGREE DIRECTION
AT SPEEDS AROUND 20KT. GUSTS WILL RANGE BETWEEN 30 AND 35 KT
THROUGH REMAINDER OF AFTERNOON WITH SLIGHTLY HIGHER GUSTS FOR
KGON.
TONIGHT...GUSTS DIMINISH 22-01Z WITH WNW WINDS 290 TO 320 DEGREES
DIRECTION TURNING MORE WESTERLY UNDER 10 KTS THEREAFTER FOR CITY
TERMINALS WITH LIGHT AND VARIABLE WINDS ELSEWHERE.
WINDS TURN MORE SOUTHWESTERLY FOR MOST TERMINALS ON FRIDAY WITH
SEA BREEZE DEVELOPMENT AT COASTAL TERMINALS.
