What happened

The episode as NWS BUF wrote it up.

A thunderstorm moving across Cattaraugus county produced a tornado. The tornado initially touched at 650 PM EDT on near Guernsey-Hollow Road in the town of South Valley in the southwest part of the county and moved across the Onoville Marina on Quaker Lake, continuing west across Allegany State Park, lifting near Route 1 in Red House at 710 PM EDT. Most of the property damage from the tornado was within in the Onoville Marina where several boats were overturned. A mobile trailer was also overturned there while several other trailers were pushed off their supports and numerous awnings were destroyed. In Allegany State Park and along Guernsey Hollow Road hundreds of trees were knocked over. Most of the damage occurred in heavily forested areas. There was notable tree damage near the Cain Hollow Campground. The tornado was rated an EF1 with a length of 13 miles and a maximum width of 100 yards.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
326 PM EDT SUN JUL 26 2009

.SYNOPSIS...
SCATTERED SHOWERS AND THUNDERSTORMS WILL WIND DOWN FAIRLY QUICKLY
THIS EVENING WITH THE LOSS OF DAYTIME HEATING. A COUPLE MORE
SHOWERS WILL BE POSSIBLE ON MONDAY...BEFORE HIGH PRESSURE FINALLY
BRINGS WARM AND DRY CONDITIONS TO THE AREA ON TUESDAY. ANOTHER
COLD FRONT APPROACHING FROM THE CENTRAL GREAT LAKES WILL BRING A
BETTER CHANCE OF SHOWERS AND THUNDERSTORMS WEDNESDAY AND WEDNESDAY
NIGHT...THEN DRY WEATHER IS EXPECTED TO RETURN DURING THURSDAY AND
LAST THROUGH THE UPCOMING WEEKEND.

&&

.NEAR TERM /THROUGH MONDAY/...
300 PM UPDATE...CONVECTION FIRED ALONG LAKE ERIES BREEZE BOUNDARY
BY NOON...WITH A SCATTERED OF SHOWERS AND A FEW STORMS EXTENDING FROM
THE CHAUTAUQUA LAKESHORE NORTHEAST TO SOUTHERN ERIE AND GENESEE TO
WESTERN MONROE EARLY THIS AFTERNOON. THIS ACTIVITY WAS WEAKENING FOR
THE MOST PART AT PRESS TIME AND EXPECT THIS TREND TO GENERALLY
CONTINUE FOR REST OF AFTERNOON INTO EARLY EVENING. STILL WILL CARRY
LIKELY POPS E OF GEN VALLEY AND FINGER LAKES FOR A FEW HOURS AND
STILL SOME POTENTIAL FOR LOCAL SEVERE FROM ABOUT ONTARIO/WAYNE
EASTWARD IN AREA OF BETTER INSTABILITY...SO WILL NEED TO KEEP AN
EYE ON THIS. WINDS HAVE VEERED ENOUGH TO ENVELOP BUF-IAG AREA IN
GOOD LK ERIE SHADOW SO FAR BUT COULD SEE A FEW LEFTOVER SHOWERS
WORKING UP LK ERIE FROM EARLIER ACTIVITY NEXT FEW HOURS SO LOW CHC
POPS HERE TILL ABOUT 22Z.

TONIGHT...WILL TAPER THREAT OF SHWRS AND TSTMS OFF FROM WEST TO EAST
DURING THE EVENING HRS KEEPING CHC POPS INTO EARLY EVENING IN THE
WEST AND INTO LATE EVENING ACROSS AREAS EAST OF THE GENESEE VALLEY.
LOWS TONIGHT GENLY IN THE LOW TO MID 60S WITH UPPER 50S ACROSS
HIGHER TERRAIN SOUTHEAST OF BUF, ACROSS THE SOUTHERN TIER.

MONDAY LOOKS TO BE A REPEAT OF TODAY WITH ONLY SLIGHTLY LESS ACTIVITY...
WITH EVER PRESENT UPPER LOW OVER THE UPPER LAKES...BUT THIS LOW WILL
SLOWLY FILL AND FLATTEN OUT...AND AIRMASS WILL BE SOMEWHAT
DRIER...BUT WITH 850 MB TEMPS ONLY 10-12C WE WILL HAVE SOME
INSTABILITY...SO CHC POPS IN AFTERNOON INLAND...BUT ONLY A 20 POP IN
BUF AND ART AREAS IN THE SHADOWS. TEMPS SHOULD ONLY REACH M-U
70S...STILL BELOW NORMAL FOR THIS NORMALLY WARMEST TIME OF THE YEAR.

WILD WEATHER DAY FROM BUF TO ROC YESTERDAY WITH AT LEAST TWO
CONFIRMED TORNADOES AND MANY REPORTS OF DAMAGE. SEE LSR AND PNS
PRODUCTS FOR FURTHER DETAILS...THESE ARE AVAILABLE ON TOP NEWS OF
THE DAY SECTION OF OUR WEBSITE.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
ANY LIMITED DAYTIME CONVECTION THAT DEVELOPS MONDAY AFTERNOON SHOULD
WIND DOWN RATHER QUICKLY MONDAY EVENING WITH THE LOSS OF DAYTIME
HEATING...LEAVING BEHIND A QUIET AND DRY REST OF THE NIGHT. WILL
COVER THE POTENTIAL FOR ANY ISOLATED LINGERING EVENING CONVECTION
WITH SLIGHT CHANCE POPS...THEN WILL INDICATE VALUES BELOW THE SLIGHT
CHANCE THRESHOLD THE REST OF THE NIGHT.

ON TUESDAY...THE AREA WILL BE UNDER THE INFLUENCE OF A DEEP
SOUTHWESTERLY FLOW OF WARM AIR PRECEDING A FRONTAL BOUNDARY THAT
WILL BE SLOWLY DROPPING SOUTHEAST ACROSS CENTRAL ONTARIO PROVINCE.
WHILE THE DAY SHOULD BE GENERALLY BE DRY WITH THE FRONTAL BOUNDARY
REMAINING FAR ENOUGH TO THE NORTH TO PRECLUDE ANY OF ITS ASSOCIATED
PRECIP FROM ENTERING THE AREA...WITH DAYTIME HEATING SOME ISOLATED
TO WIDELY SCATTERED CONVECTION COULD DEVELOP ALONG AND SOUTH OF THE
LAKE ERIE BREEZE IN THE AFTERNOON...AS HINTED AT BY BOTH THE 12Z
NAM/GFS. WILL INCLUDE SLIGHT CHANCE POPS IN THE GRIDS TO COVER THIS
POSSIBILITY...WITH DRY WEATHER INDICATED ELSEWHERE. WITH 850 MB
TEMPS RISING TO +15/+16C...SURFACE TEMPS SHOULD HAVE NO PROBLEM
RISING INTO THE LOW-MID 80S AREAWIDE.

THE REMAINDER OF THE FORECAST PERIOD WILL GRADUALLY FEATURE A RETURN
TO MORE UNSETTLED CONDITIONS AS THE AFOREMENTIONED FRONTAL BOUNDARY
APPROACHES AND THEN MOVES INTO THE AREA FROM THE NORTHWEST...WITH
THE BEST CHANCES OF CONVECTION COMING WEDNESDAY AFTERNOON AND
EVENING AS THE FRONT PUSHES INTO THE AREA DURING THE TIME OF PEAK
HEATING. WILL GRADUALLY INCREASE POPS THROUGH THE CHANCE RANGE
TUESDAY NIGHT AND WEDNESDAY MORNING...THEN QUICKLY RAMP THESE UP TO
LIKELY WEDNESDAY AFTERNOON AND EVENING AS THE BOUNDARY ARRIVES AND
ONE OR MORE WAVES RIPPLES NORTHEAST ALONG IT. GIVEN THE SYNOPTIC
SETUP...THIS PERIOD HAS THE POTENTIAL TO BE RATHER WET...AND WILL
NEED TO BE WATCHED FOR POTENTIAL HYDRO ISSUES GIVEN RECENT RAINS
ACROSS THE AREA.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
DURING THIS PERIOD...WE CONTINUE TO EXPECT THAT THE PERSISTENT GREAT
LAKES UPPER LOW WILL HAVE RETROGRADED A BIT FURTHER TO THE WEST IN
RESPONSE TO A BUILDING RIDGE OVER THE EASTERN PACIFIC...WITH THE
MEAN POSITION OF THE UPPER TROUGH AXIS LOCATED OVER THE WESTERN
LAKES/UPPER MIDWEST AS OPPOSED TO ITS CURRENT LOCATION OVER LAKE
HURON. THIS WILL ALLOW FOR GRADUAL HEIGHT RISES AND A SOUTHWESTERLY
FLOW ALOFT OVER OUR AREA AS THE WESTERN ATLANTIC SUBTROPICAL RIDGE
SLOWLY BUILDS FURTHER WESTWARD IN RESPONSE TO THE RETROGRADING LOW.
AS A RESULT...TEMPERATURES DURING THIS PERIOD SHOULD BE CLOSE TO OR
EVEN A LITTLE ABOVE NORMAL MIDSUMMER LEVELS.

AS FOR RAIN CHANCES...THE LATEST MEDIUM RANGE MODEL GUIDANCE
CONTINUES TO SUGGEST THAT WEDNESDAY NIGHTS FRONTAL BOUNDARY WILL
INITIALLY BE DRAPED ACROSS THE AREA AT THE START OF THE PERIOD...
THEN WILL GET SHUNTED SOUTH OF THE AREA DURING THE COURSE OF
THURSDAY AND THURSDAY NIGHT. THEREAFTER...RIDGING BETWEEN THIS
DEPARTING FRONT AND ANOTHER SYSTEM TRACKING ACROSS THE UPPER
MIDWEST/UPPER GREAT LAKES SHOULD BRING GENERALLY DRY WEATHER FOR THE
FRIDAY-SUNDAY PERIOD. WILL CONTINUE TO INDICATE DECREASING CHANCE
POPS THURSDAY AND THURSDAY NIGHT AS THE FRONT DEPARTS TO OUR
SOUTH...WITH SLIGHT CHANCE OR LOWER POPS THEN FOLLOWING FOR FRIDAY
AND THE UPCOMING WEEKEND.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
CONDITIONS SHLD GENLY BE VFR ACROSS MUCH OF THE REGION FOR THE 24
HOUR TAF PERIOD...BUT BRIEFLY LOWERING TO MVFR/IFR IN ANY
SHOWERS/TSTORMS. BEST CHC OF THIS WOULD BE UNTIL 00Z AT THE KROC
AND KJHW SITES. ANY ACTIVITY SHLD WIND DOWN THIS EVENING IN THE
WEST AND THEN AFTER 06Z EAST OF LK ONTARIO. SOME FOG IS POSSIBLE
ACROSS PORTIONS OF THE SOUTHERN TIER LATE TONIGHT.

OUTLOOK...
MONDAY NIGHT AND TUESDAY...MAINLY VFR.
WEDNESDAY...MVFR IN SHOWERS/THUNDERSTORMS.
THURSDAY...VFR/MVFR IN MORNING SHOWERS.
FRIDAY...MAINLY VFR.

&&

.MARINE...
MARINERS SHOULD BE ON ALERT FOR SCATTERED THUNDERSTORMS LATE THIS
AFTERNOON AND EVENING. OTHERWISE...CONDITIONS WILL REMAIN BELOW
SMALL CRAFT CRITERIA THROUGH AT LEAST TUESDAY.

&&

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