The radar

The Burlington radar (KCXX), 110 km from the middle of the area, began a volume at 21:45 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, 9.7 hours before the alert went out and 127 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 23, 4:15 PM EDT, 1 hour 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
415 PM EDT SUN JUN 23 2013

.SYNOPSIS...
WARM TEMPERATURES...HIGH HUMIDITY...AND DAILY CHANCES FOR
AFTERNOON SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH MID
WEEK. SOME OF THE STORMS COULD PRODUCE BRIEF HEAVY RAINFALL AS
THEY PASS. DAILY HIGHS IN THE 80S TO NEAR 90 SOME DAYS CAN BE
EXPECTED...ALONG WITH MUGGY LOWS IN THE 60S. A COOLING TREND WILL
DEVELOP LATER IN THE WEEK WHEN A TROUGH OF LOW PRESSURE SETTLES
OVER THE AREA...HOWEVER CHANCES FOR RAIN WILL PERSIST.

&&

.NEAR TERM /UNTIL 8 AM MONDAY MORNING/...
AS OF 400 PM EDT SUNDAY...SHOWERS/THUNDERSTORMS BECOMING MORE
ORGANIZED LATE THIS AFTERNOON IN MODEST INSTABILITY OF 1500 J/KG
CAPE. MAIN DRIVER FOR SEVERE WEATHER IS 850 MB WESTERLY JET
TRANSLATING ACROSS THE REGION...AND COINCIDING WITH MAX
INSTABILITY. SHOULD BE AN EARLY SHOW WITH JET FORECAST TO
DISSIPATE BY 00Z. OVERNIGHT TONIGHT PRECIP CHANCES DECREASE WITH
LOSS OF DAYTIME HEATING AND INSTABILITY. HEAVY RAINFALL
INGREDIENTS IN PLACE...PWATS NEAR 1.75 INCHES AND CLOSE TO 2
STANDARD DEVIATIONS ABOVE NORMAL...WARM CLOUD DEPTH OVER
10KFT...AND MBE VECTORS INDICATING POTENTIAL TRAINING/BACKBUILDING
STORMS. RIGHT NOW EVERYTHING IS MOVING ALONG...HOWEVER REPORTS OF
3/4 TO 1 INCH RAINFALL IN LESS THAN AN HOUR AS STORMS MOVE OVER.

MUGGY NIGHT ON TAP WITH LOWS GENERALLY IN THE 60S. PATCHY FOG
POSSIBLE FOR THE USUAL SUSPECTS 06-12Z OVERNIGHT. WENT WITH MODEL
BLENDS AND RELIED ON BIAS CORRECTIONS TO BRING MIN TEMPS UP.
DAYTIME MAXES HAVE BEEN TRENDING A DEGREE OR TWO BELOW GUIDANCE
WITH CLOUDS AND RAIN...AND TRIED TO CONTINUE WITH MAX TEMP TREND.

&&

.SHORT TERM /8 AM MONDAY MORNING THROUGH TUESDAY NIGHT/...
AS OF 400 PM EDT SUNDAY...SLOW HEIGHT RISES THROUGH THE SHORT TERM
PERIOD...WITH CONTINUATION OF PRESENT WEATHER. HOT HUMID DAYS AND
WARM MUGGY NIGHTS. SURFACE HIGH NUDGES NORTH...ALTHOUGH AT 500MB
WESTERLY FLOW BRINGS SERIES OF WEAK SHEARED VORT MAXES ACROSS THE
AREA. ABSENT ANY CAPPING RIDGE ALOFT...ENOUGH SURFACE HEATING TO
GENERATE CONVECTIVE STORMS EACH AFTERNOON. LIKE TODAY...MODEST
CAPE...WEAK SHEAR...AND PLENTY OF INGREDIENTS FOR HEAVY RAINFALL
FROM THUNDERSTORMS.

LATE TUESDAY INTO TUESDAY NIGHT PRECIP CHANCES BECOME MORE FOCUSED
WHEN SHORTWAVE TROUGH WITH ORIGINS FROM WESTERN CANADA CLOSED LOW
REACHES OUR REGION. GFS AND ECMWF BOTH IN DECENT AGREEMENT THAT
THIS FEATURE MOVES THROUGH TUESDAY AFTERNOON THROUGH NIGHT...WITH
A SURFACE TROUGH/WEAK FRONT SHIFTING WINDS NORTHWEST BEHIND. POPS
FOR THIS FEATURE TO RAMP UP WEST TO EAST...AND RUN A LITTLE HIGHER
THAN WHAT WE'VE SEEN FOR THE REST OF THE WEEK.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
AS OF 415 PM EDT SUNDAY...UNSETTLED WEATHER CONTINUES THROUGHOUT
THE LONG TERM AS ZONAL FLOW ALLOWS SEVERAL SHORTWAVE TROUGHS MOVE
THROUGH THE REGION. WITH PERSISTENT SW FLOW...WARM MOIST AIR WILL
CONTINUE TO FILTER INTO THE NORTH COUNTRY...KEEPING THINGS WARM
AND MUGGY...AS WELL AS AID IN INSTABILITY. THIS WILL RESULT IN
CHANCE FOR SHOWERS AND THUNDERSTORMS EVERY DAY IN THE LONG TERM
FORECAST. THE LATTER HALF OF THE WEEK INTO THE WEEKEND WILL HAVE
THE BEST CHANCES FOR THUNDERSTORMS AND MORE PERSISTENT RAIN AS AN
UPPER LEVEL CLOSED LOW DEEPENS OVER THE NORTHEAST AND WILL BE
SLOW TO MOVE OUT OF THE AREA...KEEPING WET CONDITIONS IN PLACE.

MAX TEMPERATURES WILL GENERALLY BE IN THE M70S-L80S IN THE
VALLEYS AND U60S-L70S IN THE HIGHER TERRAIN. OVERNIGHT MIN
TEMPERATURES WILL RANGE FROM THE M50S-M60S.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
THROUGH 18Z MONDAY...A WEAK QUASI-STATIONARY FRONTAL BOUNDARY HAS
BECOME THE FOCUS FOR RAIN SHOWER AND THUNDERSTORM DEVELOPMENT
THIS AFTERNOON. VRB CONDITIONS WITH SHOWERS AND THUNDERSTORMS
MAINLY DEVELOPED OVER NRN NY INTO THE CPV AND TRAVELING EWD.
GENERALLY VFR CONDITIONS...WITH MVFR CONDITIONS IN HZ...SHOWERS
AND THUNDERSTORMS WILL PRODUCE PERIODS OF MVFR IN HEAVY RAINFALL.
HAVE INCLUDED VCTS AT ALL SITES THIS AFTERNOON AS SHOWERS ARE
WIDESPREAD AND HAVE PLENTY OF INSTABILITY TO DEVELOP INTO
THUNDERSTORMS...ESP FROM THE CENTRAL CPV SOUTHWARD. THE WEAK
QUASI-STATIONARY BOUNDARY WILL GAIN SOME MOMENTUM SOUTHWARD LATE
THIS AFTERNOON INTO THE EVENING...GRADUALLY DECREASING THE THREAT
FOR SHRA AND TSRA FROM NORTH TO SOUTH. AFTER MIDNIGHT...WILL
LIKELY SEE DRYING TREND WITH MVFR/IFR BR/FG DEVELOPMENT
POSSIBLE...ESP IN AREAS THAT HAVE SEEN RAINFALL DURING THE DAY.
WITH CONTINUED MUGGY CONDITIONS...BR/FG MAY BE GRADUAL TO BURN
OFF MONDAY MORNING.

OUTLOOK 18Z MONDAY THROUGH FRIDAY...DAYTIME VFR CONDITIONS
EXPECTED WITH THE EXCEPTION OF BRIEF MVFR/IFR IN HEAVIER
SHOWERS/THUNDERSTORMS MAINLY DURING THE AFTERNOON AND EVENING
HOURS. OVERNIGHT/EARLY MORNING MVFR/IFR PATCHY FOG AND MIST
DEVELOPMENT WILL BE POSSIBLE IF ANY TAF SITE RECEIVES HEAVY
RAINFALL FROM CONVECTION DURING THE DAYTIME.

&&

.MARINE...
LAKE THUNDERSTORM ADVISORY IN EFFECT THROUGH THIS EVENING. FIRST
ROUND OF STORMS HAVE MOVED OVER LAKE...HOWEVER AREA FROM SOUTH
HERO SOUTH THROUGH BROAD LAKE TO SOUTHERN END STILL UNDERPOTENTIAL
FOR STRONG THUNDERSTORMS THROUGH EVENING. A BAND OF WIND IN THE
