Damaging Wind in New York, July 9, 2007

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
329 PM EDT MON JUL 9 2007

.SYNOPSIS...
HEAT AND HUMIDITY WILL BE THE RULE FOR ANOTHER 36 TO 48 HOURS
BEFORE A COLD FRONT USHERS IN A CHANGE TO COOLER WEATHER ON
WEDNESDAY. THERE WILL BE A RISK OF THUNDERSTORMS DURING THE
AFTERNOON AND EVENING HOURS THROUGH TUESDAY. A MORE CONCENTRATED
AREA OF SHOWERS AND STORMS WILL ACCOMPANY THE FRONTAL PASSAGE ON
WEDNESDAY. COOLER DRIER AIR WILL FOLLOW THURSDAY AND ON THROUGH
THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
ACTIVITY BLOSSOMING ON ALL LAKE BREEZE BOUNDARIES AT MID
AFTERNOON. EXPECT SOME OF IT TO GO SEVERE AND WATCH ISSUED UNTIL 9
PM FOR THE ENTIRE AREA. LOOK FOR MOST CONCENTRATED ACTIVITY ALONG
THESE BOUNDARIES FROM CATT CO TO FINGER LAKES...AND NIAG/ORLEANS
COS FROM SRN ONTARIO. ACTIVITY SHOULD LAST INTO THE EVENING BEFORE
WINDING DOWN AFTER DARK. VERY WEAK FRONT PROGGED TO DISSIPATE
OVERNIGHT AS IT REACHES OUR REGION. THIS WILL DO NOTHING TO
RELIEVE THE OPPRESSIVE WX...JUST REDUCE THE WINDS. WILL KEEP SLGT
CHC ALL NIGHT.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
WE WILL REMAIN IN THE WARM AND STEAMY AIRMASS TUESDAY AS
AFOREMENTIONED FRONT WILL HAVE WASHED OUT. COULD BE A TAD LESS HUMID
OVER NORTH COUNTRY BUT REST OF US WILL STILL BE MUGGY WITH DEW PTS
NEAR 70. ONE DIFFERENCE TUESDAY WILL BE THAT WINDS BOTH ALOFT AND
AT SFC WILL BE MUCH LIGHTER THAN TODAY. THIS MAY REDUCE THE RISK
OF SVR WX A BIT...ALTHOUGH STILL CANT BE RULED OUT...WILL PLAY
SIMILAR POPS AS TODAYS 30 WIDESPREAD BUT 20 IMMED BUF AREA.
LIGHTER WINDS THOUGH MAY ALLOW BUF TO ACTUALLY BE A FEW DEG
WARMER THAN TODAY...NEAR 90. GENERALLY DRY TUES NT.

MODELS A BIT FASTER WITH THE FRONT ON WED...TAKING IT THROUGH BUF
BY NOON AND ERN ZONES LATER IN AFTERNOON. THIS TIMING WILL NOT BE
FAVORABLE IN FAR WEST FOR SEVERE WX BUT A POSSIBILITY FOR OUR
EASTERN ZONES. WILL GO WITH LIKELY POPS FOR A FEW HOURS WITH
FRONTAL PASSAGE...WITH SOME CLEARING IN WEST LATER IN DAY.

WED NT AND THURS LOOK MUCH MORE PLEASANT AS RIDGE SCOOTS BY TO OUR
SOUTH. MAY SEE AN INCREASE IN CLOUD LATE THURS BUT WILL PLAY IT
DRY WITH 8-10C 850MB TEMPS SUPPORTING U70S OR SO.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
THIS PERIOD LOOKS TO FEATURE A NORTHWEST FLOW ALOFT AS UPPER
TROUGH PERSISTS OVER THE AREA. ASSOCIATED COOL AIR ALOFT WILL
COMBINE WITH DAYTIME HEATING TO GENERATE A FEW AFTERNOON SHOWERS
DURING THE FIRST HALF OF THE PERIOD...BUT GENERALLY FOLLOWED HPC
GUIDANCE AND KEPT CHANCES TO NO MORE THAN A SLIGHT CHANCE. A
REINFORCING COLD FRONT WILL BRING A BETTER CHANCE FOR CONVECTION
TO THE AREA LATE SATURDAY AFTERNOON AND SATURDAY NIGHT. MOST OF
THE PERIOD SHOULD FEATURE TEMPERATURES AT OR SLIGHTLY BELOW
NORMAL.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
PLENTY OF INSTABILITY AND SHEAR INTO THE EARLY PART OF THIS
EVENING...WITH ALL OF WESTERN AND CENTRAL NEW YORK IN THE WARM
SECTOR SOUTH OF A WARM FRONT ACROSS FAR NORTHERN NEW YORK AND COLD
FRONT ACROSS LOWER MICHIGAN. SURFACE WINDS DOWNWIND OF THE
LAKES...ESPECIALLY AT BUFFALO AND WATERTOWN WILL GUST TO NEAR 30
KNOTS THROUGH 00Z.

EXPECT CONVECTION TO DEVELOP ALONG BOUNDARY ACROSS SOUTHERN ONTARIO
AS WORK INTO THE AREA FROM THE NORTHWEST AFTER 20Z...IN ADDITIONAL
CONVECTION IS EXPECTED TO DEVELOP ALONG LAKE BREEZE BOUNDARY SOUTH
AND EAST OF BUFFALO AND EXTEND UP THROUGH THE FINGER LAKES. THESE
LINES OF CONVECTION COULD BECOME LOCALLY SEVERE WITH THE POTENTIAL
FOR LARGE HAIL AND WIND GUSTS OVER 50 KNOTS. THIS COULD BRING THE
POTENTIAL FOR AVIATION RESTRICTIONS.

LATER TONIGHT THE WEAKENING COLD FRONT WILL MOVE INTO THE WEST...
PROBABLY WITHOUT ANY CONVECTION. THIS FEATURE HOWEVER WILL ACT TO
REMOVE THE WIND.

THIS BOUNDARY WILL LINGER INTO TUESDAY WITH ANOTHER CHANCE FOR
AFTERNOON CONVECTION. A STRONG COLD FRONT WILL APPROACH TUESDAY
NIGHT AND MOVE THROUGH THE STATE ON WEDNESDAY. EXPECT THE
POSSIBILITY OF A SOLID LINE OF CONVECTION ON WEDNESDAY WITH
POSSIBLE SOME AVIATION RESTRICTIONS. HIGH PRESSURE OVER THE OHIO
VALLEY WILL BRING VFR CONDITIONS BACK TO THE AREA LATER WEDNESDAY
NIGHT AND THURSDAY.

&&

.MARINE...
SOUTHWEST WINDS OF 15 TO 18 KNOTS EARLY THIS EVENING WILL CREATE
WAVE HEIGHTS AROUND 3 FEET ALONG THE NEARSHORE WATERS OF LAKE ERIE.
WINDS WILL DIMINISH TONIGHT. WINDS AND WAVES ARE EXPECTED TO REMAIN
BELOW SMALL CRAFT ADVISORY CRITERIA TUESDAY AND WEDNESDAY.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
NY...NONE.
MARINE...NONE.
