What happened

The episode as NWS BUF wrote it up.

Slow moving thunderstorms during the late afternoon hours produced torrential rains of three to four inches across parts of the Genesee Valley and Finger Lakes. In South Bristol, Ontario county, the intersection of Hicks and Seneca Point Roads was closed until crews could clear mud and debris carried by flood waters. In Centerville, Allegany county, a bridge was washed out on Pratt Road.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Buffalo, NY wrote its last area forecast discussion before the first event at Jun 29, 8:30 AM EST, 4 hours 40 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
930 AM EDT WED JUN 29 2005

.MID-MORNING UPDATE
CURRENTLY WE ARE MONITORING AN EAST-WEST LINE OF SHOWERS AND A FEW
EMBEDDED THUNDERSTORMS THAT EXTEND FROM LONG POINT ONTARIO THROUGH
ROCHESTER TO SYRACUSE. WITH VERY WEAK WIND FIELD THE BIGGEST THREAT
FROM THIS ACTIVITY WILL BE VERY HEAVY RAINFALL. CELLS ARE MOVING
ALONG...ALBEIT SLOWLY...AT 5 TO 10 MPH SO UNLESS WE BEGIN TO GET
TRAINING ACTIVITY I DO NOT EXPECT FLOODING TO BE A THREAT. HOWEVER
WE WILL MONITOR RADAR AND NEAR STORM ENVIRONMENT CLOSELY FOR ANY
SUGGESTION OF TRAINING CELLS. CLOUD COVER WILL KEEP TEMPS DOWN A BIT
AS WE GET INTO THE AFTERNOON BUT DEWPOINTS IN THE MID TO UPPER 60S
WILL MAKE IT FEEL UNCOMFORTABLE ONCE AGAIN.

WATER VAPOR IMAGERY SHOWS A FAIRLY WELL DEFINED SHORT WAVE THAT IS
PICKED UP PRETTY WELL ON MODELS TO MOVE THROUGH WNY BY 00Z.  THAT
WAVE COULD FORCE MORE CONVECTION DURING THE EARLY TO MID PART OF THE
AFTERNOON.  CURRENT FORECAST WILL REMAIN AS IS FOR NOW. I STILL FEEL
THAT THE BIGGEST THREAT THROUGH THE AFTERNOON FOR CONVECTIVE
ACTIVITY WILL BE HEAVY RAINFALL....THOUGH RAIN LOADED DOWNDRAFTS
COULD PRODUCE LOCALIZED WIND GUSTS.

.SHORT TERM (THIS AFTERNOON THROUGH FRIDAY)...

SECONDARY WAVE WILL SHIFT EAST OF THE AREA TONIGHT AS SHORT WAVE
RIDGING AND ASSOCIATED DRIER AIR DEVELOPS OVER THE AREA. ANOTHER
VERY WARM DAY THURSDAY AS 850 MB TEMPERATURES FORECAST TO WARM TO
NEAR +18C UNDER MODEST AMOUNT OF SUNSHINE SHOULD YIELD AFTERNOON
HIGHS WELL IN THE 80S AND CLOSE TO 90F.

SUBTLE WARM FRONT APPROACHES THE AREA LATE THURSDAY NIGHT AS RIDGE
SLIDES EAST OF THE AREA. THIS COULD PRODUCE A CHANCE FOR CONVECTION
ACROSS WESTERN SECTIONS LATE THURSDAY NIGHT.

SIGNIFICANT CANT COLD FRONT CROSSES THE AREA FRIDAY...A LITTLE
SLOWER THAN PREVIOUS MODEL RUNS. THIS FRONT SHOULD BRING WIDESPREAD
AND RATHER ACTIVITY CONVECTION. BIG CHANGES BEHIND THE FRONT WITH
850 MB TEMPERATURES DROPPING TO NEAR +5C BY SATURDAY MORNING AS
HUMIDITY GETS FLUSHED FROM THE AREA.

&&

.LONG TERM (SATURDAY THROUGH TUESDAY)...

WILL BRING IN REALLY NICE COMFORTABLE WEATHER FOR THE WEEKEND AS WE
GET INTO A BIG CHANGE IN AIRMASS BEHIND THE COLD FRONT.  THERE IS A
SUGGESTION ON A SECONDARY SHORT WAVE ROTATING AROUND THE MAIN UPPER
LOW ACROSS THE EASTERN GREAT LAKES SATURDAY BUT FOR NOW I DO NOT
EXPECT ANY PRECIPITATION.  SUNDAY LOOKS GREAT AS WELL AS THE HOLIDAY
...THOUGH LATE IN THE DAY THE GUIDANCE SUGGESTS THE NEXT FRONT FROM
THE WEST APPROACHES WNY.  ALTHOUGH MOTHER NATURES FIREWORKS HAVE
BEEN PART OF OUR RECENT JULY 4TH HOLIDAYS I WILL STAY POSITIVE AND
KEEP ANY MENTION OF PRECIPITATION OUT FOR NOW THEN REINTRODUCE IT ON
TUESDAY.

&&

.AVIATION...

MVFR TO IFR CIGS AND VSBYS IN SCATTERED SHOWERS AT KBUF AND KROC
SHOULD IMPROVE TO VFR BY 16-17Z. LOOK FOR GENERALLY VFR CONDITIONS
AT OTHER SITES THROUGH THIS EVENING AFTER SOME HAZE THINS AT
KJHW...THOUGH LOCAL THUNDERSTORM ACTIVITY CANNOT BE RULED OUT.

&&

.MARINE...

LIGHT WESTERLY WINDS WILL HANG ON THROUGH MOST OF THE AFTERNOON BUT
TEND TO SHIFT TO NORTH AND NORTHEAST OVER LAKE ONTARIO LATE THIS
AFTERNOON AND EARLY THIS EVENING. WAVES WILL REMAIN LESS THAN TWO
FEET.

&&

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