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

Albany, NY (KALY), launched 00:00Z, 3.5 hours before the alert went out and 78 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, Jun 8, 7:37 PM EDT, 3 hours 51 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
737 PM EDT WED JUN 8 2011

.SYNOPSIS...
A COLD FRONT WILL MOVE THROUGH THE AREA ON THURSDAY AFTERNOON...BRINGING
NUMEROUS SHOWERS AND THUNDERSTORMS. THE FRONT WILL BRING COOLER
AND MORE COMFORTABLE CONDITIONS EXPECTED FRIDAY. ANOTHER LOW
PRESSURE SYSTEM WILL BRING ANOTHER ROUND OF SHOWERS AND STORMS
SATURDAY AFTERNOON.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
HIGH PRESSURE WILL HANG ON FOR A LITTLE LONGER TONIGHT. A COLD
FRONT THAT IS EXPECTED TO MOVE THROUGH THE CWA TOMORROW IS STILL
WELL TO THE WEST, KEEPING ANY GOOD FORCING OUT OF THE REGION.
THERE IS STILL A SMALL POSSIBILITY THAT A STORM OR TWO COULD
DEVELOP THIS EVENING AND OVERNIGHT. CONFIDENCE IS VERY LOW ON
THIS. SPC HAS SCALED BACK THERE SLIGHT CHANCE TO THE VERY
NORTHERN EDGE OF THE CWA. WITH HIGHER DEW POINTS AND VERY WARM
TEMPS TODAY, LOW TEMPERATURES TONIGHT LOOK TO BE IN THE MID TO
UPPER 60S.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/...
MODELS DIFFER ON THE TIMING OF A COLD FRONT THAT IS PROGGED TO
MOVE THROUGH. WHILE THEY ALL HAVE THE FRONT PASSING THROUGH, SOME
BRING IT THROUGH QUICK AND WELL PASSED THE CWA, WHILE OTHERS ARE
SLOWER AND STALL IT OUT JUST TO THE SOUTH OF THE CWA. EITHER WAY,
IT WILL MAKES ITS WAY ACROSS THE REGION TOMORROW MID DAY. THIS
WILL ALLOW SHOWERS AND THUNDERSTORMS TO DEVELOP ACROSS THE ENTIRE
CWA. MODELS PUT CAPE VALUES BETWEEN 1000 AND 2000 J/KG TOMORROW.
MORE THAN ENOUGH WITH A COLD FRONT ACTING AS A TRIGGER. 0-1KM BULK
SHEAR IS NOT TOO IMPRESSIVE DURING THE MID DAY. THE 0-3 IS A
LITTLE BETTER AT 20 TO 30 KTS. 0-6KM SHEAR IS BETTER AT AROUND 40
TO 45KTS. LOOKING AT THIS, THE MAIN THREATS WOULD LIKELY BE WIND
AND HAIL.

BEHIND THE COLD FRONT, HIGH PRESSURE WILL BUILD BACK IN. TEMPS
WILL BE COOLER THROUGH THE WEEKEND, AS WELL AS LOWER DEW POINTS.
HOWEVER, WITH THE FRONT LIKELY STALLING SOMEWHERE FROM CENTRAL PA
TO SOUTHERN PA, THERE WILL POSSIBLY BE SOME LINGERING SHOWERS AND
STORMS IN THE PA ZONES INTO SATURDAY. ANOTHER LOW WILL MOVE INTO
THE GREAT LAKES REGION, BRINGING YET ANOTHER CHANCE FOR SHOWERS
AND STORMS ON SATURDAY AFTERNOON.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
SOMEWHAT FLAT LONG WV TROF OVES FROM THE CNTRL LAKES INTO THE NE
STATES DURING THE LONG TERM. PASSAGE OF A COLD FNT EARLY IN THE PD
WILL BRING THE BEST CHANCE OF TRW...FLWD BY LWRD CHANCES THRU THE
PD WITH THE LWRD HGTS BRINGING SOME AFTN INSTABILITY. AS
USUAL...GFS IS MORE PROGRESSIVE WITH THE SYSTEM BUT EVEN SO KEEP
THE AREA IN A NW FLOW THRU WED. PTRN SHD KEEP COOLER THAN NRML AIR
IN THE AREA THRU THE PD.

HPC GUID IN GOOD AGREEMENT WITH XTNDD MOS GUID SO USED HPC GUID
WITH JUST A FEW TWEAKS.
