The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Buffalo Intl Airport, NY (KBUF), launched 12:00Z, 9.1 hours before the alert went out and 36 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
347 PM EDT THU AUG 19 2010
.SYNOPSIS...
A COLD FRONT WILL SLIDE SOUTHEAST ACROSS OUR REGION THIS EVENING
ACCOMPANIED BY SHOWER AND THUNDERSTORM ACTIVITY OVER PARTS OF THE
AREA. HIGH PRESSURE FROM THE UPPER LAKES REGION WILL BUILD IN BEHIND
THE FRONT AND PRODUCE BEAUTIFUL COMFORTABLE DAY FRIDAY. THE HIGH IS
THEN FORECAST TO MOVE OFF THE EAST COAST SATURDAY. A SOUTHERLY FLOW
OF WARMER MORE HUMID AIR WILL DEVELOP OVER THE REGION DURING THE DAY
SATURDAY BUT ANY SHOWER OR THUNDERSTORM ACTIVITY SHOULD HOLD OFF
UNTIL SATURDAY NIGHT AND SUNDAY WHEN AN UPPER AIR DISTURBANCE AND A
SURFACE BASED COLD FRONT IS FORECAST TO MOVE THROUGH.
&&
.NEAR TERM /THROUGH FRIDAY/...
OUR ONLY REAL CONCERN WITH THIS FORECAST PERIOD IS THIS EVENING AS A
COLD FRONT WILL BE SLIDING SOUTHEAST ACROSS THE REGION. A LITTLE
SURPRISED AS OF THE WRITING THAT WE ARE NOT GETTING A LITTLE MORE
ACTION ALONG THE FRONT BUT THE LATEST HRRR DOES INDICATED ONLY
SCATTERED ACTIVITY. THE ONLY LIKELY OR HIGHER POPS WILL BE RESERVED
FOR THE EASTERN LAKE ONTARIO REGION WHERE THERE IS AN ORGANIZED LINE
APPROACHING.
A QUICK END TO ANY ACTIVITY LATER THIS EVENING. WILL HAVE CHANCE
POPS LATEST IN FOR THE SOUTHERN TIER BUT BASICALLY NOTHING EVEN
THERE AFTER MIDNIGHT. A CLEARING TREND THE REST OF THE NIGHT.
PROBABLY SOME VALLEY FOG FORMING IN THE SOUTHERN TIER. SUBSIDENCE
WITH HIGH PRESSURE BUILDING IN FRIDAY WILL LEAD TO GREAT SUMMER
WEATHER WITH DEW POINTS IN THE 50S ALONG WITH MAINLY SUNNY SKIES.
850 MB TEMPS AROUND 12C SHOULD YIELD HIGHS IN THE MID TO UPPER 70S.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
HIGH PRESSURE CENTERED OVER QUEBEC WILL NOSE SOUTHWARDS ACROSS NEW
YORK STATE FRIDAY NIGHT AND SATURDAY WHILE A MID LEVEL SHORTWAVE
WILL CROSS THE UPPER GREAT LAKES. THIS WILL LEAD TO A COMFORTABLE
FRIDAY NIGHT...THEN WITH WARM ADVECTION FULLY UNDERWAY...A WARM DAY
SATURDAY. H85 TEMPS BY SATURDAY AFTERNOON WILL BE IN THE MID TO
UPPER TEENS (CELSIUS)...AND EVEN WITH SOME MID/UPPER LEVEL CLOUD
COVER...SFC TEMPS SHOULD BE ABLE TO CLIMB INTO THE LOW TO MID 80S.
THESE VALUES WILL BE AS MUCH AS 10 DEGREES F ABV NORMAL.
THE 00 AND 06Z MODEL RUNS WERE SLOWER IN BRINGING PCPN ACROSS OUR
FORECAST AREA FOR LATE SATURDAY...SO POPS WERE LOWERED TO SLIGHT
CHC. THE LATEST PACKAGES ARE BACK TO BRINGING PCPN IN BY LATE
AFTERNOON...BUT TO AVOID FLIP FLOPPING BETWEEN MODEL RUNS...WILL
KEEP THE SLGT CHC POPS THAT WE HAVE IN PLACE. IN EITHER CASE...THE
VAST MAJORITY OF SATURDAY SHOULD BE RAIN FREE WITH WARM WEATHER AND
PARTIAL SUNSHINE.
THE MID LEVEL SHORTWAVE WILL CROSS OUR FORECAST AREA SATURDAY NIGHT
WHILE ITS ASSOCIATED SFC TROUGH WILL CROSS LAKE ERIE. WILL RAISE CHC
POPS TO LIKELY FROM THE FINGER LAKES WESTWARD...AND BECAUSE OF THE
STEEP LAPSE RATES SUGGESTED BY THE GFS...WILL UPGRADE THE POTENTIAL
FOR THUNDERSTORMS. EARLIER FORECASTS ONLY HAD ISOLATED STORMS IN THE
GRIDDED DATA...BUT WILL USE CHC POPS FOR STORMS WHICH WLL NOW
INCLUDE THEM WITHIN THE WRITTEN ZONE PACKAGE.
AS FOR TEMPERATURES SATURDAY NIGHT...THE GFS BASED MAV GUIDANCE
LOOKS A LITTLE LOW GIVEN THE H85 TEMPS OF 16C+...CLOUD COVER AND
DEPTH OF OVERALL SOUTHERLY FLOW. WILL THUS LEAN MUCH CLOSER TO THE
NAM BASED MET NUMBERS...WHICH WILL ALSO MAKE OUR REGION STAND OUT A
LITTLE MORE VERSUS SURROUNDING WFO'S. MINS SAT NIGHT FOR OUR REGION
WILL GENERALLY BE IN THE MID TO UPPER 60S. WOULD NOT BE SURPRISED TO
SEE THE IAG FRONTIER STAY AT OR ABV 70 THAT NIGHT.
THE UNSETTLED WEATHER SATURDAY NIGHT WILL THEN LEAD INTO A FAIRLY
WET SUNDAY WHEN THE SFC TROUGH WILL EASE ACROSS OUR FORECAST AREA.
OUR POPS HAVE BEEN FURTHER RAISED TO HIGH LIKELY (70) FOR MUCH OF
SUNDAY...AND DESPITE THE CLOUD COVER AND RESULTING PCPN...SFC TEMPS
SHOULD STILL MAKE THEIR WAY TO INTO THE UPPER 70S TO NEAR 80.
A HIGH AMPLITUDE H5 RIDGE EXTENDING FROM THE NATIONS MID SECTION
NORTHWARDS ACROSS ONTARIO SUNDAY AFTERNOON WILL EXTEND FURTHER EAST
ACROSS QUEBEC DURING THE COURSE OF SUNDAY NIGHT...WHILE THE DIGGING
TROUGH WILL REMAIN OVER THE EASTERN GREAT LAKES AND NEW ENGLAND.
MEANWHILE AT THE SFC...A NEARLY STATIONARY INVERTED TROUGH WILL BE
STRETCHED NORTHEAST TO SOUTHWEST ACROSS OUR FORECAST AREA. THE
PRESENCE OF THIS TROUGH WILL CERTAINLY BE ENOUGH TO WARRANT KEEPING
CHC POPS FOR SOME SHOWERS OVER THE REGION FOR SUNDAY NIGHT.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
A HIGH AMPLITUDE RIDGE OVER THE GREAT LAKES AND EASTERN CANADA ON
MONDAY WILL GIVE WAY TO A FLATTER...LOW AMPLITUDE H5 FLOW DURING
THIS PERIOD. THIS SHOULD GENERALLY LEAD TO ABOVE NORMAL TEMPERATURES
WITH DAYTIME HIGHS MAINLY IN THE 80S. 30 YEAR NORMALS FOR THIS
PERIOD ARE IN THE MID 70S FOR DAYTIME HIGHS AND MID-UP 50S FOR
OVERNIGHT LOWS. SOME DETAILS...
THE PROTRUDING RIDGE OVER EASTERN CANADA ON MONDAY WILL GRADUALLY
SINK ACROSS THE LOWER GREAT LAKES AND ST LAWRENCE VALLEY LATE MONDAY
AND MONDAY NIGHT AS A VERY VIGOROUS SHORTWAVE WILL CROSS THE
CANADIAN PRAIRIES. WHILE THERE COULD BE A LEFTOVER SHOWER PRODUCED
BY THE DEPARTING TROUGH ON MONDAY...THE VAST MAJORITY OF THE DAY
SHOULD BE RAIN FREE.
MORE SIGNIFICANT CLEARING SHOULD THEN BE NOTED MONDAY NIGHT AND
TUESDAY AS THE RIDGE WILL SETTLE ACROSS OUR FORECAST AREA. H85 TEMPS
IN THE MID TEENS TUESDAY AFTERNOON SHOULD MAKE TUESDAY ANOTHER 'WARM
ONE' WITH MAX TEMPS IN THE LOW TO MID 80S.
A COLD FRONT IS THEN EXPECTED TO CROSS THE REGION ON WEDNESDAY. THE
FRONT SHOULD NOT HAVE MUCH MOISTURE TO WORK WITH...SO WILL ONLY USE
CHC LOW CHC POPS FROM THIS VANTAGE POINT AND CALL IT SHOWERS WITH
ISOLATED TSRA.
A BROAD RIDGE IS EXPECTED TO BUILD ACROSS THE NATIONS MIDSECTION AND
UPPER GREAT LAKES FOR THURSDAY...WHILE CANADIAN HIGH PRESSURE WILL
SETTLE OVER OUR AREA. THIS SHOULD SUPPORT FAIR COOLER WEATHER...
WHICH SHOULD PERSIST INTO AT LEAST FRIDAY.
&&
.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
A NORTHEAST SOUTHWEST ORIENTED COLD FRONT APPROACHING TORONTO AND
KITCHNER AS OF 18Z IS FORECAST TO SLIDE SOUTHEAST ACROSS OUR CWA
THIS EVENING. SCATTERED SHOWER AND THUNDERSTORM ACTIVITY WILL
ACCOMPANY THE FRONT WITH CONDITIONS BRIEFLY LOWERING TO MVFR. A
CLEARING TREND WILL FOLLOW THE FRONT LATE THIS EVENING AND
OVERNIGHT. BEFORE DAYBREAK MVFR VSBYS ARE POSSIBLE ESPECIALLY AT
KROC AND IFR POSSIBLE AT KJHW.
OUTLOOK...
FRIDAY AND SATURDAY...GENERALLY VFR.
SATURDAY NIGHT AND SUNDAY...VFR/OCCASIONAL MVFR WITH A CHANCE FOR
SHOWERS.
MONDAY AND TUESDAY...VFR.
&&
.MARINE...
WINDS WILL CONTINUE BRISK AS A COLD FRONT APPROACHES FROM THE
NORTHWEST. SMALL CRAFT ADVISORIES WILL REMAIN IN PLACE THROUGH 8 PM
THIS EVENING FOR EASTERN LAKE ERIE AND THE UPPER NIAGARA RIVER AND
BUFFALO HARBOR.
THE WINDS WILL SHIFT TO THE NORTH NORTHWEST BEHIND THE FRONT THIS
EVENING AND TONIGHT. THE CORRESPONDING WAVES MAY APPROACH SCA
CRITERIA ALONG THE SOUTH SHORES OF LAKE ONTARIO. WE WILL NOT ISSUE
ANY SMALL CRAFT ADVISORIES FOR THAT AREA BUT THEY MAY BE NEEDED
LATER.
WIND AND WAVES WILL DIMINISH FRIDAY AS HIGH PRESSURE CRESTS OVER
NEW YORK STATE.
