The radar

The Albany radar (KENX), 117 km from the middle of the area, began a volume at 12:26 UTC, the scan nearest the moment this went out.

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 flash flood 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, 0.4 hours before the alert went out and 135 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 flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Binghamton, NY wrote its last area forecast discussion before this flash flood warning went out at Jun 22, 7:13 AM EDT, 1 hour 11 minutes earlier.

Area forecast discussion, Jun 22, 7:13 AM EDT, 1 hour 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
713 AM EDT WED JUN 22 2011

.SYNOPSIS...
A WARM FRONT WILL MOVE THROUGH THE AREA TODAY, WITH MORE WIDESPREAD
SHOWERS AND THUNDERSTORMS. RAIN MAY BE HEAVY AT TIMES. SHOWERS
AND THUNDERSTORMS WILL CONTINUE INTO FRIDAY WHEN A COLD FRONT
CROSSES THE AREA.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
UPDATED AT 1055Z...FIRST HEAVY LINE OF SHOWERS HAS MOVED THROUGH
THIS MORNING. SOME LIGHT RAIN IS DEVELOPING IN THE WESTERN ZONES.
FORECAST LOOKS TO BE ON TRACK FOR THE DAY. NO MAJOR CHANGES TO THE
GRIDS WITH THE EXCEPTION OF TIMING THE LINE OF STORMS IN THE EAST.

PREVIOUS DISCUSSION...A WARM FRONT IS BEGINNING TO MOVE THROUGH
THE CWA. THERE IS A LINE OF SHOWERS AND STORMS THAT IS ASSOCIATED
WITH IT. THIS LINE WILL CONTINUE TO MOVE ACROSS THE CWA THROUGH
THE MORNING HOURS.

ONCE THE LINE IS THROUGH, THE CWA WILL BE IN THE WARM SECTOR.
CONDITIONS ARE IN PLACE FOR SHOWERS AND THUNDERSTORMS TODAY.
LOOKING AT SEVERAL FACTORS, CURRENT THINKING IS THE MAIN THREAT
WILL BE HEAVY RAIN. PWATS WILL BE ABOVE 1.75 AND EVEN JUST OVER 2
INCHES IN SOME AREAS. THE NAM HAS GOOD MBE VELOCITY UNTIL EARLY
THIS AFTERNOON, WHEN THEY DROP BELOW 10 KTS. GFS IS VERY SIMILAR.
MODELS ARE ALSO INDICATING WARM CLOUD LAYERS FROM 11K TO 12K
TODAY. CAPE VALUES THIS AFTERNOON LOOK TO GENERALLY BE LESS THAN
1000 JOULES, AND EVEN LESS THAN 500 JOULES IN SOME LOCATIONS. THE
NCAPE SITS AROUND .1. SO, AGAIN, THINKING THAT WHILE THERE WILL BE
THUNDERSTORMS, THE MAIN THREAT WILL BE SLOW MOVING STORMS WITH
HEAVY RAIN. SPC DOES HAVE THE SW ZONES FROM YATES COUNTY SE TO
SOUTHERN WAYNE COUNTY OUTLOOKED FOR A SLIGHT CHANCE OF SEVERE
WEATHER TODAY. BUT CONFIDENCE IS LOW AT THIS TIME. THEY HAVE THE
MAIN THREAT AS CONVECTIVE WIND GUSTS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
WITH THE WARM FRONT TO THE NORTH AND THE COLD FRONT WELL TO THE
WEST TOMORROW, THE CWA WILL BE IN THE WARM SECTOR. WITH PLENTY OF
MOISTURE AROUND AS WELL AS INSTABILITY, WE WILL LIKELY SEE ANOTHER
ROUND OF SHOWERS AND STORMS. PWATS DO COME DOWN CONSIDERABLE,
ACCORDING TO THE MODELS, SO THE HEAVY RAIN THREAT LOOKS TO BE MUCH
LOWER ON THURSDAY.

BY THURSDAY NIGHT, MODELS LOOK TO HAVE THE FRONT OCCLUDE AND HAVE
THAT PUSH THROUGH BY FRIDAY MORNING. THIS SHOULD REDUCE THE CHANCE
FOR STORMS ON FRIDAY, BUT KEEPS A CHANCE OF SHOWERS AND STORMS
WITH THE LOW HANGING OUT OVER THE GREAT LAKES REGION.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
UPDATED AT 300 PM...
FOLLOWED HPC GUIDANCE CLOSELY DURING THIS PERIOD. SOMEWHAT UNSETTLED
CONDITIONS ARE FORECAST AT THE BEGINNING OF THIS PERIOD WITH THE
AREA GETTING BEHIND A COLD FRONT ON FRIDAY NIGHT...FOLLOWED BY A
LINGERING UPPER LEVEL TROF AND CHANCES FOR SHOWERS INTO SATURDAY.
HIGH PRESSURE IS THEN SLOWLY FORECAST TO BUILD INTO THE REGION FROM
SUNDAY THROUGH TUESDAY. ECMWF/GFS/CANADIAN GGEM AND ENSEMBLE MEANS
ARE IN REASONABLE AGREEMENT WITH THIS SCENARIO AND CREST THE CENTER
OF THE HIGH OVER CNY/NEPA ON MONDAY-TUESDAY. HPC GUIDANCE CONTINUED
TO INDICATE LOW CHC POPS...BUT GIVEN THE SYNOPTIC PATTERN WE REDUCED
THEM TO A DRY FORECAST. THERE IS SOME SUGGESTION IN THE 00Z
ECMWF/12Z GFS MODELS THAT A WEAK UPR LVL FEATURE WILL COME THROUGH
THE REGION ON TUESDAY...BUT AT THIS TIME IT APPEARS OF LOW AMPLITUDE
AND WOULD PREFER TO NOT HAVE RAIN CHANCES IN FCST AT THIS TIME.

TEMPERATURE FIELDS LOOK TO BE SEASONAL FOR THIS TIME OF YEAR WITH
DAYTIME READINGS IN THE UPPER 70S TO LOW 80S AND LOWS IN THE 50S-MID
60S.

&&

.AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
UPDATED AS OF 7 AM WED... SCTD SHRA WILL DOT THE AREA FOR MUCH OF
THE DAY...WITH TSRA BECOMING MORE LIKELY BY LATE AFTN. FOR
NOW...WE'LL CARRY SOME MVFR RESTRICTIONS THROUGH 15Z...THEN
CONTINUE TO ADVERTISE CB GROUPS BY ARND 20Z. TSRA WILL BE ADDED AT
INDIVIDUAL SITES...AS NEEDED.

MVFR RESTRICTIONS IN BR/HZ EXPECTED AFTER DARK...WITH A MOIST/LGT
FLOW ENVIRONMENT.

LIGHT WINDS EARLY THIS MORNING...WILL BECOME SRLY BY AFTN...AT
5-8 KT...THEN TURN LIGHT AFTER 00Z THU.

OUTLOOK...

THURSDAY THROUGH SATURDAY...PERIODS OF MVFR...IN SCATTERED TO
WIDESPREAD SHOWERS AND THUNDERSTORMS.

SUNDAY...VFR.

&&
