AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
327 PM EDT SAT MAY 8 2010
.SYNOPSIS...
LOW PRESSURE WILL BRING SCATTERED SHOWERS AND STRONG... GUSTY
WINDS TO THE AREA THIS EVENING. THE STORM WILL ALSO BRING MUCH
COOLER WEATHER TO THE AREA TONIGHT. SCATTERED RAIN SHOWERS WILL
CHANGE TO SCATTERED SNOW SHOWERS OR FLURRIES IN MANY AREAS LATER
TONIGHT INTO SUNDAY MORNING. HIGH PRESSURE WILL BRING DRY...
UNSEASONABLY COOL WEATHER SUNDAY NIGHT INTO MONDAY. THE NEXT
CHANCE OF RAIN WILL BE TUESDAY AS LOW PRESSURE APPROACHES FROM THE
SOUTHWEST.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
SATELLITE LOOPS SHOW STRONG...VERTICALLY STACKED LOW PRESSURE
SPINNING FROM LAKE HURON EAST TOWARD NORTHERN NEW YORK. BANDS OF
SHOWERS ROTATING AROUND THE STORM WILL MOVE ACROSS THE AREA
THROUGH EARLY THIS EVENING. GUSTY WINDS AND ISOLATED SMALL HAIL
HAVE BEEN REPORTED WITH THESE SHOWERS.
STRONGEST WINDS ASSOCIATED WITH THIS SYSTEM SHOULD MOVE ACROSS THE
AREA THIS EVENING IN ASSOCIATION WITH A PRONOUNCED AREA OF STRONG
PRESSURE RISES ON THE BACKSIDE OF THE STORM. STRONG PRESSURE RISE
MAXIMA AND COLD ADVECTION WILL ACT TO ENHNACE WIND GUSTS THIS
EVENING... ALLOWING 40 TO 55 KT GUSTS TO AFFECT SOME AREAS. THE
STRONGEST PRESSURE TENDENCY GRADIENT IS FORECAST ACROSS THE
NORTHERN PART OF THE FORECAST AREA... AND THIS IS WHERE WE HAVE
OUR WARNING IN EFFECT FOR GUSTS NEAR TO JUST OVER 50 KTS. FARTHER
SOUTH EXPECT 40 TO 45 KT GUSTS. WINDS WILL GRADUALLY DIMINISH
LATER TONIGHT AS THE STRONGEST ISALLOBARIC FORCING MOVES OFF TO
THE EAST.
SCATTERED SHOWERS WILL PERSIST OVERNIGHT... ENHANCED BY 850 MB
TEMPERATURES FALLING TO AS LOW AS -9 DEGREES C... WHICH WILL
RESULT IN SOME LAKE EFFECT PRECIPITATION SOUTHEAST OF LAKE
ONTARIO. THE PRECIPITATION WILL BE IN THE FORM OF LIGHT RAIN
SHOWERS THROUGH MID-EVENING... BUT COOLER AIR WILL RESULT IN A
CHANGE TO LIGHT SNOW SHOWERS OVERNIGHT... ESPECIALLY OVER THE
HIGHER ELEVATIONS. A SMALL ACCUMULATION OF SNOW COULD OCCUR OVER
HIGHER TERRAIN SOUTHEAST OF LAKE ONTARIO... AND HAVE GONE WITH
AMOUNTS AROUND HALF AN INCH OVER HIGHER TERRAIN IN ONEDIA AND
ONONDAGA COUNTIES SOUTHEAST TO DELAWARE COUNTY. ELSEWHERE
TEMPERATURES REMAIN JUST ABOVE FREEZING AND WARM GROUND SHOULD
KEEP ANY LIGHT SHOWERS FROM ACCUMULATING.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/...
THINGS QUIET DOWN BY SUNDAY AFTERNOON. BUILDING HIGH PRESSURE WILL
BRING PARTIAL CLEARING... WITH ANY LEFT-OVER SPRINKLES OR FLURRIES
ENDING BY NOON.
VERTICALLY STACKED CLOSED LOW OVER NRN NEW ENGLAND WILL DRIFT SLOWLY
INTO THE WESTERN NORTH ATLANTIC WITH HIGH PRESSURE BUILDING IN SFC
AND ALOFT THROUGH TUESDAY. ALTHOUGH THE GENERAL WX WILL BECOME
FAIR...AN UNSEASONABLY COOL AIRMASS WILL REMAIN OVER THE REGION WITH
TEMPERATURES BELOW NORMAL. ANOMALOUSLY COOL AIRMASS WITHIN
CLEARING SKIES AT NIGHT WILL ALLOW FOR SUB FREEZING TEMPERATURES AT
NIGHT AND A THREAT TO THE GROWING SEASON. WILL ISSUE A FREEZE WATCH
FOR SUNDAY NIGHT WITH THIS UPDATE...AND ANOTHER ONE WILL LIKELY BE
NEEDED FOR MONDAY NIGHT AS THERE WILL ACTUALLY BE AN EVEN BETTER
CHANCE OF WIDESPREAD FROST AND FREEZING CONDITIONS WITH WINDS
EXPECTED TO BE LIGHTER THAN TOMORROW NIGHT. ON TUESDAY...NAM/GFS ARE
IN FAIR AGREEMENT WITH THIS PROGRESSIVE PATTERN THAT A WARM FRONT
WILL MOVE TOWARD THE AREA ON TUESDAY. THERE APPEARS TO BE A GOOD
CHANCE OF RAIN DEVELOPING FROM WEST-EAST DURING THE AFTERNOON. GIVEN
MODEL CONSENSUS...WE MADE SOME ADJUSTMENTS TO THE TIMING IN THE FCST
TO IMPROVE THE MORNING HOURS AND ALSO LOWERED TEMPERATURES A FEW
DEGREES TO ACCOUNT FOR LESS WARMING DUE CLOUDS/RAIN CHANCE.
&&
.LONG TERM /TUESDAY THROUGH SATURDAY/...
UNSETTLED AND COOL PERIOD WITH WEAK SLOW MOVING SFC SYSTEM. ALOFT
WEAK TROFS MOVE THROUGH. THE FIRST SYSTEM GOES THROUGH TUESDAY
NIGHT TO WEDNESDAY. THERE MAY BE A DRY BREAK ESPECIALLY IN THE
NORTH THURSDAY BEFORE THE NEXT SFC SYSTEM MOVES THROUGH FRIDAY
NIGHT. THE GFS AND EURO ARE CLOSE IN STRENGTH AND TIMING ON THE
FIRST SYSTEM BUT DIVERGE ON THE SECOND. THE GFS IS FASTER AS IS
TYPICAL. HAVE SIDED WITH HPC AND THE EURO FOR THE END OF THE LONG
TERM.
&&
.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
LOW PRESSURE MOVING ACROSS LOWER ONTARIO WILL KEEP A TIGHT
PRESSURE GRADIENT ACROSS CNTRL NY WITH STRONG AND GUSTY WINDS
GOING OVER CNY/NEPA THROUGH TONIGHT. W-NW WINDS 20-30 KTS WILL
GUST 35-50 KTS WITH THE PERIOD OF STRONGEST WINDS EXPECTED BETWEEN
21Z-05Z. GUSTS WILL DIMINISH SOMEWHAT OVERNIGHT TO AROUND 25 KTS.
CIGS WILL START IN THE VFR CATEGORY...THEN DECREASE TO MVFR AS
SECONDARY COLD FRONT SWEEPS THROUGH THE REGION WITH SHOWERS AND
OCNL MVFR VSBYS. COLDER MORE UNSTABLE AIR WILL SPREAD OVER THE
REGION OVERNIGHT WITH CIGS BECOMING OVC MVFR WITH RAIN SHOWERS
MIXING WITH SNOW SHOWERS THROUGH EARLY SUNDAY MORNING. LITTLE TO
