| Time | Report | Where | Remark |
|---|---|---|---|
| Jul 7, 12:00 PM EDT | HAIL 0.75 | 1 E Theresa, NY |
Local storm reports filed while the alert was in force, from inside its polygon or its counties.
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
Albany, NY (KALY), launched 12:00Z, 3.8 hours before the alert went out and 231 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.

What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Jul 7, 11:12 AM EDT, 36 minutes earlier.
Area forecast discussion, Jul 7, 11:12 AM EDT, 36 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 1112 AM EDT TUE JUL 7 2009 .SYNOPSIS... A PERSISTENT UPPER LOW OVER ONTARIO WILL MOVE SLOWLY EAST AND KEEP COOL AND UNSETTLED CONDITIONS ACROSS OUR REGION INTO WEDNESDAY. THE LOW WILL FINALLY PULL EAST AND RELEASE ITS GRIP LATER IN THE WEEK AND HIGH PRESSURE SHOULD BRING A RETURN TO DRY AND MORE TYPICAL WARM JULY WEATHER FOR THURSDAY AND FRIDAY. A COLD FRONT WILL CROSS THE AREA LATE SATURDAY WITH ANOTHER THREAT OF SHOWERS...TO BE FOLLOWED BY HIGH PRESSURE AND DRIER COOLER CONDITIONS AGAIN BY THE END OF THE WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... EXPECT ANOTHER UNUSUALLY COOL AND MOSTLY CLOUDY DAY ALONG WITH A THREAT FOR MORE SHOWER AND THUNDERSTORM ACTIVITY...WHICH WILL AGAIN BE FORCED BY THE APPROACH AND PASSAGE OF VARIOUS SHORTWAVE IMPULSES ROTATING AROUND THE QUEBEC UPPER LOW. ONE SUCH LOBE WILL DROP ACROSS THE CENTRAL GREAT LAKES AND SWING THROUGH THE BASE OF THE UPPER LOW TODAY...WITH SCATTERED SHOWERS OVER WESTERN TO CENTRAL NY AND SHOWERS LIKELY WITH SCATTERED THUNDERSTORMS OVER THE NORTH COUNTRY. THERE ARE SUBTLE DIFFERENCES IN THE MODELS WHICH SHOW VARYING QPF FIELDS...THE GFS RESTRICTS THE PRECIP MAINLY TO THE NORTH COUNTRY AND NAM SHOWS WHAT APPEAR TO BE DIURNALLY DRIVEN SHOWERS OVER MOST OF THE FORECAST AREA. SREF ALSO SHOWS A WIDER SPREAD OF PRECIP AND HIGHER POPS FOR THE WESTERN AND CENTRAL ZONES...EVEN GOING WITH CATEGORICAL FOR THE TUG HILL REGION. WILL BLEND IN SOME OF THE SREF POPS AND USE NAM QPF TO SHOW A WIDER COVERAGE OF PRECIP CHANCES...STILL HIGHEST OVER THE NORTH COUNTRY. WILL CONTINUE WITH THE TREND OF DIMINISHING POPS FROM WEST TO EAST AS THE NIGHT PROGRESSES AND THE UPPER LOW STARTS TO MOVE OVER NORTHERN NY...THEN HEADS TOWARD NORTHERN NEW ENGLAND ON WEDNESDAY...FILLING A BIT IN THE PROCESS. MAX TEMPS TODAY WILL BE 10-13 DEGREES BELOW NORMAL WITH HIGHS IN THE MID TO UPPER 60S ACROSS THE ALLEGANY PLATEAU LOCALES AND FOR THE EASTERN LAKE ONTARIO REGION...AND THE UPPER 60S TO THE LOW 70SS ACROSS THE LAKE PLAINS. LOWS TONIGHT WILL BE IN THE UPPER 40S FOR MUCH OF THE INTERIOR COUNTIES FROM THE SOUTHERN TIER TO THE FINGER LAKES...AS WELL AS ACROSS THE TUG HILL TO BLACK RIVER VALLEY...LOWER TO MID 50S ELSEWHERE. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... THE UPPER LEVEL LOW WILL BE CENTERED NEAR THE SAINT LAWRENCE VALLEY AT THE START OF THE PERIOD...BUT THE LOW WILL BE IN THE PROCESS OF WEAKENING AND PULLING EAST. HOWEVER...A SHORTWAVE ROTATING AROUND THE LOW CENTER WILL PUSH ACROSS THE AREA KEEPING THE THREAT FOR SCATTERED SHOWERS...ESPECIALLY EAST OF LAKE ONTARIO IN AREA OF DEEPER MOISTURE. AIR ALOFT STILL COLD ENOUGH TO MENTION THE RISK FOR SOME THUNDERSTORM ACTIVITY. 850 MB TEMPERATURES OF PLUS 6C TO PLUS 8C WILL YIELD YET ANOTHER COOL DAY WITH HIGHS GENERALLY IN THE UPPER 60S TO LOWER 70S...STILL SOME TEN DEGREES BELOW NORMAL. THURSDAY LOOKS TO BE A DRY DAY WITH UPPER TROUGH CONTINUING TO PULL EASTWARD. 850 MB TEMPERATURES RECOVERING TO NEAR PLUS 10C...WILL SUPPORT MORE SEASONABLE HIGHS IN THE MID TO UPPER 70S. UPPER RIDGING BECOMING ESTABLISHED ACROSS THE REGION THURSDAY NIGHT WITH FAIR WEATHER EXPECTED. && .LONG TERM /FRIDAY THROUGH MONDAY/... UPPER RIDGING BUILDS BRIEFLY ONTO OUR AREA FRI WITH A WEAK SOUTHERLY SFC FLOW. TEMPS WARM FURTHER ALOFT...TO 15C ON BOTH ECMWF AND GFS...SO MOST AREAS SHOULD HAVE LITTLE TROUBLE BREAKING THE 80 DEG MARK FOR THE FIRST TIME THIS MONTH. ECMWF AND HPC GRAPHICS SHOW A DRY DAY...BUT 12Z GFS SUDDENLY INDICATED A SWATH OF CONVECTION IN ASSOCIATION WITH AN ELEVATED WARM FRONT WHICH WOULD WORK ITS WAY ACROSS WESTERN NY FRI MORNING. WILL IGNORE THIS FOR NOW AND CHALK IT UP TO CONVECTIVE FEEDBACK...BUT WILL CARRY 20 POPS JUST IN CASE IT IS ON TO SOMETHING. FOLLOWED HPC GRAPHICS FOR SAT-MON WITH COLD FRONTAL PASSAGE LATE SAT NT...GFS IS MUCH FASTER WITH IT...DURING SAT. WILL THEREFORE KEEP AREA IN WARM SECTOR ON SAT WITH CHC POPS AND TEMPS NEAR 80...COOLER AND DRIER SUNDAY AND MONDAY BUT NOT FAR FROM NORMAL WITH 850 MB TEMPS IN 10-13C RANGE FOR BOTH SUN AND MON. BUT...CONFIDENCE IN WEEKEND DETAILS IS QUITE LOW AT THIS STAGE. && .AVIATION /15Z TUESDAY THROUGH SATURDAY/... AN UPPER LEVEL LOW WILL REMAIN NEARLY STATIONARY OVER WESTERN QUEBEC. AS THIS FEATURE SITS AND SPINS IN PLACE...SPOKES OF SHORTWAVE ENERGY ROTATING AROUND ITS CENTER WILL CONTINUE THE THREAT OF PERIODIC SHOWERS AND POSSIBLE THUNDERSTORMS ACROSS THE FORECAST AREA...THOUGH THE EXACT TIMING AND PLACEMENT OF THESE WILL CONTINUE TO BE HIGHLY UNCERTAIN. FOR THIS REASON...HAVE GENERALLY CONTINUED TO INDICATE NO MORE THAN VCSH/CB QUALIFIERS IN THE TAFS AT THIS TIME...WITH THESE TIED TO THE APPROXIMATE TIMES OF PASSAGE OF THE MAIN SHORTWAVE FEATURES. SHOULD MORE DEFINITIVE AREAS OF CONVECTION EVENTUALLY DEVELOP. ALL THE ABOVE SAID...ASIDE FROM LOCALIZED MVFR CONDITIONS POSSIBLE IN ANY SHOWERS/STORMS...CONDITIONS SHOULD GENERALLY REMAIN VFR THROUGH THE FORECAST PERIOD. OUTLOOK... WEDNESDAY...VFR/MVFR WITH A CHANCE OF SHOWERS EAST OF THE GENESEE VALLEY. THURSDAY AND FRIDAY...VFR. SATURDAY...VFR/MVFR WITH A CHANCE OF SHOWERS/THUNDERSTORMS. && .MARINE... NO MARINE FLAGS EXPECTED THIS WEEK. MODERATE WEST TO SOUTHWEST WINDS WILL DEVELOP ON THE LAKES TODAY...BUT REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA. LOOK FOR LIGHTER WINDS LATER IN THE WEEK AS AN UPPER LOW PULLS OUT AND SURFACE HIGH PRESSURE SETTLES IN ACROSS THE LOWER LAKES FOR THURSDAY AND FRIDAY. && .BUF WATCHES/WARNINGS/ADVISORIES...
