The episode as NWS BUF wrote it up.
Following the passage of a strong cold front, strong synoptic winds developed across western New York. The strong winds downed trees and power lines. In Niagara County, several power poles were snapped in the hurricane-force winds. In Alabama, Genesee county, a tractor trailer was blown over by the winds. Specific measured wind gusts included: 83 mph at Niagara Falls Airport; 63 mph at Buffalo Airport and Youngstown; 62 mph at Rochester Airport; 61 mph at Barcelona; 60 mph at Olcott; and 58 mph at Jamestown Airport and Grand Island.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
742 AM EDT THU APR 28 2011
.SYNOPSIS...
A SHARP COLD FRONT WILL SWEEP ACROSS THE REGION FROM WEST TO EAST
THIS MORNING. BEHIND THE COLD FRONT...STRONG WINDS AND SHOWERS
WILL OCCUR ACROSS THE REGION. SHOWERS WILL LINGER INTO FRIDAY AS
AN UPPER LEVEL TROUGH PASSES ACROSS THE REGION.
&&
.NEAR TERM /THROUGH TONIGHT/...
LINE OF SEVERE CONVECTION JUST OFF TO OUR SOUTH AND EAST EARLY THIS
MORNING. RADAR TRENDS KEEP THIS ACTIVITY OFF TO OUR SOUTH AND EAST
SO NO SEVERE CONCERNS THIS MORNING...BUT HEAVY RAINS STILL A
DECENT POSSIBILITY THEREFORE WILL MAINTAIN THE FLASH FLOOD WATCH
FOR EASTERN AREAS THROUGH THE MORNING. FLOOD ADVISORY CURRENTLY
IN EFFECT FOR PORTIONS OF LEWIS COUNTY UNTIL 6 AM FOR THE 1-1.5
INCHES OF RAIN WHICH FELL OVERNIGHT THERE. THE FLASH FLOOD WATCH
WILL BE CANCELLED FOR WESTERN SECTIONS.
SURFACE ANALYSIS AT 07Z SHOWING A 989 MB LOW NEAR DETROIT WITH THE
SURFACE COLD FRONT SLICING THROUGH CENTRAL OHIO. UPSTREAM RADARS
SHOWING SCATTERED LOW TOPPED CONVECTION DEVELOPING ALONG AND AHEAD
OF THE FRONT. THOUGH NOT SEVERE AT THIS TIME...THE DEVELOPMENT OF
THIS CONVECTION WILL NEED TO BE MONITORED CLOSELY THROUGH THE
EARLY MORNING. INSTABILITY OVER THE AREA IS LIMITED...BUT A STRONG
LOW LEVEL JET AT OR ABOVE 50 KNOTS WILL ALLOW FOR THE POTENTIAL
FOR DAMAGING WIND GUSTS. EXTRAPOLATION WOULD BRING THE COLD FRONT
INTO FAR WESTERN PORTIONS OF THE AREA BETWEEN 11Z AND 13Z...THEN
REACHING EASTERN SECTIONS BETWEEN 16Z AND 18Z.
BEHIND THE FRONT...STRONG WINDS WILL DEVELOP. ASSOCIATED SURFACE
LOW WILL DEEPEN A BIT MORE AS IT TRACKS JUST TO THE NORTHWEST OF THE
AREA TODAY...REACHING WESTERN QUEBEC BY THIS AFTERNOON.
UPSTREAM SURFACE OBSERVATIONS ALREADY SHOWING WIND GUSTS ACROSS
WESTERN OHIO EXCEEDING 50 KNOTS. MOMENTUM TRANSFER SCHEME OFF BUFKIT
SOUNDINGS DOWNWIND OF LAKE ERIE SUPPORTING POTENTIAL WIND GUSTS OF
50 TO 60 KNOTS. THEREFORE...WE WILL UPGRADE THE WIND ADVISORY TO
A HIGH WIND WARNING FOR THE LAKE ERIE SHORE LINE AND THE FAVORABLE
SOUTHWEST WIND CORRIDOR FROM BUFFALO TO ROCHESTER. THE STRONGEST
WINDS PROBABLY OCCUR WITHIN A 3 TO 6 HOUR PERIOD FROM 12Z TO 18Z.
WIND ADVISORY WILL BE MAINTAINED ELSEWHERE...EXCEPT FOR EASTERN
SECTIONS WHERE WIND FIELDS WILL NOT BE QUITE AS STRONG.
SHARP TEMPERATURE DROP WILL ALSO OCCUR WITH THE FRONTAL PASSAGE IN A
STRONG COLD AIR ADVECTION REGIME. SHARP MID LEVEL DRY SLOT WILL
DIMINISH PRECIPITATION BEHIND THE FRONT...BUT COLD AIR ADVECTION
COULD LEAD TO SCATTERED DIURNAL INSTABILITY SHOWERS.
POTENTIAL FOR WRAP AROUND SHOWER ACTIVITY TONIGHT WITH WINDS
DIMINISHING.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY/...
COOL UNSETTLED WEATHER WILL PREVAIL THROUGH FRIDAY AS AN UPPER LEVEL
TROUGH AND ASSOCIATED SURFACE TROUGH SWING EAST ACROSS OUR CWA. THE
GFS LIFTS THE TROUGH OUT A LITTLE FASTER THAN THE NAM...SO THE
STEADIEST SHOWERS MAY IMPACT THE AREA DURING THE FIRST HALF OF THE
DAY. IT WILL BE UNSEASONABLY COOL ON FRIDAY WITH MOST AREAS
REMAINING IN THE 40S. ANY REMAINING SHOWERS SHOULD END QUICKLY
FRIDAY NIGHT AS THE AXIS OF THE UPPER LEVEL TROUGH SHIFTS EAST INTO
NEW ENGLAND.
HIGH PRESSURE RIDING OVER NEW YORK STATE WILL BRING MOSTLY SUNNY
SKIES AND MILDER TEMPERATURES ON SATURDAY. AS THE HIGH SETTLES OFF
THE MIDDLE ATLANTIC COAST SATURDAY...A COLD FRONT WILL APPROACH FROM
THE CENTRAL GREAT LAKES. THERE WILL BE A GRADUAL WEST TO EAST
INCREASE IN CLOUDS ASSOCIATED WITH WARM AIR ADVECTION AHEAD OF THE
FRONT...BUT EXPECT ANY SHOWERS TO HOLD OFF UNTIL SUNDAY MORNING.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
MODELS CONTINUE TO SUGGEST AN UNSETTLED PATTER FOR SUNDAY AND INTO
NEXT WEEK. AN UPPER LEVEL TROF WILL PASS TO THE NORTH...HOWEVER
MODELS HAVE CONSISTENTLY DIFFERED ON THE TIMING OF THIS...WITH
DISAGREEMENT STEMMING FROM WHEN AND IF THIS WILL CUT OFF. LEAN
TOWARD THE MORE PROGRESSIVE SOLUTIONS OF THE 12Z GFS/GGEM...THOUGH
SLOWER SOLUTION OF THE 00Z EURO IS POSSIBLE. DURING THE
TIME...TEMPERATURES SHOULD BE FAIRLY SEASONABLE...PERHAPS ON THE
COOL SIDE.
&&
.AVIATION /12Z THURSDAY THROUGH MONDAY/...
A STRONG COLD FRONT WILL MOVE ACROSS NEW YORK STATE THROUGH 18Z.
A NARROW LINE OF LOW TOPPED CONVECTION WILL ACCOMPANY THE FRONT.
IN THE WAKE OF THE COLD FRONT EXPECT STRONG WINDS ALOFT TO MIX
DOWN TO THE SURFACE WITH STRONG WINDS ACROSS MOST OF THE TAF SITES
THROUGH MUCH OF THE DAY...WITH STRONGEST WINDS FROM KROC WEST.
EXPECT MAINLY VFR...THOUGH SOME SCATTERED SHOWERS WILL BRING
OCCASIONAL MVFR FLIGHT CONDITIONS. WINDS WILL GUST 40 TO 50KNOTS
ACROSS THE WESTERN TAF SITES...AND KROC TERMINAL WITH GUSTS NOT
QUITE AS HIGH AT KART...WHICH WILL BE FARTHER AWAY FROM THE LOW
CENTER AND GREATEST PRESSURE RISES CAUSING THE WINDS.
OUTLOOK...
THURSDAY NIGHT AND FRIDAY...MVFR/VFR. A CHANCE OF SHOWERS.
SATURDAY...VFR.
SUNDAY AND MONDAY...MVFR/VFR IN A CHANCE OF SHOWERS.
&&
.MARINE...
GALE WARNINGS WILL BE MAINTAIN FOR LAKE ERIE AND CENTRAL AND
WESTERN PORTIONS OF LAKE ONTARIO AS A DEEPENING SURFACE LOW PASSES
JUST TO THE WEST OF BOTH LAKES TODAY. SOUTHWEST WIND GUSTS OF 40
TO 45 KNOTS WILL MIX DOWN IN FAVORABLE COLD AIR ADVECTION.
FARTHER FROM THE SURFACE LOW...SMALL CRAFT ADVISORY CONDITIONS
WILL DEVELOP FOR THE EASTERN PORTION OF LAKE ONTARIO AND THE SAINT
LAWRENCE RIVER.
