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
Caribou, ME (KCAR), launched 00:00Z, 9.7 hours before the alert went out and 166 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
NATIONAL WEATHER SERVICE CARIBOU ME
429 AM EDT TUE OCT 30 2012
.SYNOPSIS...
POST TROPICAL STORM SANDY WILL CONTINUE TO AFFECT OUR REGION WITH
SIGNIFICANT RAIN AND BREEZY CONDITIONS TODAY THROUGH WEDNESDAY.
UNSETTLED WEATHER WILL REMAIN THROUGH LATE WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
MAIN CHALLENGE WILL TURN TO THE FLOOD POTENTIAL AS POST TROPICAL
STORM SANDY MOVES WEST AND CONTINUES TO WEAKEN.
FLOOD WATCH REMAINS IN PLACE AND WILL BE DISCUSSED IN DETAIL
BELOW. WIND AND COASTAL FLOOD THREAT HAS PRETTY MUCH ENDED AND
COORDINATED WITH GYX TO DROP WIND AND COASTAL FLOOD HEADLINES
W/THE 4 AM PACKAGE. WILL COORDINATE THIS AS WELL W/HPC AT THE 4 AM
CONFERENCE CALL.
LARGE CIRCULATION AROUND SANDY WILL BRING DEEP MOISTURE INTO THE
REGION THROUGH TONIGHT IN THE FORM OF RAIN. EMBEDDED TROPICAL
CHARACTERISTICS WILL BE FELT ACROSS THE CWA DURING THIS TERM.
LATEST IR/WV SATL IMAGERY SHOW A LARGE TROPICAL CONNECTION COMING
IN FROM THE ATLC OCEAN W/HIGH PWATS >1.25 INCHES. MDL SOUNDINGS
SHOW COLUMN MOISTENING UP THROUGH 500MBS TODAY W/A DEEP ESE FLOW.
THIS COMBINED W/A K INDEX OF 35+ WILL LEAD TO PERIODS OF HEAVY
RAIN. DECENT LLVL CONVERGENCE WILL AID IN HEAVIER RAINFALL AS WILL
THE POTENTIAL FOR SOME EMBEDDED TSTMS. MDL SOUNDINGS & BUFKIT
PROFILES SHOW ELEVATED CAPE OF 25-450 JOULES W/TOTAL TOTALS
HITTING 50+ AND A SWEAT INDEX OF AROUND 300. BASED ON THESE
VALUES, CAN NOT RULE OUT SOME STORMS DUMPING VERY HEAVY RAINFALL
AND GUSTY WINDS. THEREFORE, DECIDED TO ADD HEAVY RAINFALL AND KEEP
GUSTY WINDS THROUGH LATE THIS AFTERNOON. THERE WILL BE A BREAK IN
THE STEADY RAIN FOR A TIME EARLY EVENING AND THEN ANOTHER SURGE AS
MORE RAIN MOVES WNW FROM THE ATLC OCEAN W/PERIODS OF HEAVY RAINFALL.
ADJUSTMENTS WERE MADE TO THE QPF TO KNOCK BACK THE 00-06Z VALUES.
USED A BLEND OF THE LATEST HPC AND NERFC THROUGH THIS MORNING AND
THEN STAYED CLOSE TO THE DAYCREW'S VALUES FOR CONSISTENCY.
MORE ON THIS WILL BE DISCUSSED IN THE HYDROLOGY SECTION BELOW.
TEMPERATURES WERE RAISED USING THE LATEST LAMP AND NAM12 VALUES
SHOWING UPPER 50S TO LOWER 6S0 ACROSS THE NORTH AND LOW TO MID 60S
FOR CENTRAL AND DOWNEAST TODAY. TEMPERATURES WILL FALL BACK INTO
THE 50S.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
POST TROPICAL SANDY WILL REMAIN WEST OF THE REGION AND WEAKEN
THROUGH THURSDAY. THIS WILL RESULT IN ABUNDANT CLOUD COVER AND
PERIODS OF SHOWERS WEDNESDAY AND INTO THURSDAY. HIGH TEMPERATURES ON
WEDNESDAY WILL BE NEAR 60 DEGREES ACROSS THE REGION AND THEN THE MID
TO UPPER 50S ON THURSDAY. LOWS WEDNESDAY NIGHT WILL BE IN THE MID TO
UPPER 40S.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AN UPPER LEVEL TROF WILL REMAIN ACROSS THE REGION THROUGH SATURDAY.
THE WILL KEEP THE CHANCE OF SHOWERS ACROSS THE REGION. THE TROF WILL
MOVE EAST SUNDAY ALLOWING HIGH PRESSURE TO BUILD EAST. ANOTHER AREA
OF LOW PRESSURE WILL TRACK TOWARD THE REGION ON MONDAY.
&&
.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
NEAR TERM: MVFR ACROSS THE NORTHERN TERMINALS W/IFR FOR KBGR AND
KBHB. ALL TERMINALS WILL SEE IFR LATER THIS MORNING THROUGH TONIGHT.
THERE IS THE POTENTIAL FOR PERIODS OF MVFR AS AIRMASS DESTABILIZES
W/BRIEF BREAKS IN THE CLOUD COVER THIS AFTERNOON.
SHORT TERM: MVFR CONDITIONS ARE LIKELY ON WEDNESDAY IN PERIODS OF
SHOWERS. SCT SHOWERS WITH MVFR/VFR LIKLEY THURSDAY. MAINLY VFR
FRIDAY/SATURDAY.
&&
.MARINE...
NEAR TERM: STORM WARNING HAS BEEN DOWNGRADED TO A GALE WARNING.
WINDS ARE GUSTING TO 35+ KTS W/SEAS NOW CLIMBING TO 14-16 FT PER
THE LATEST OBS. LATEST SWAN GUIDANCE HAS BROUGHT THE SEAS DOWN
FROM 20 FT EARLIER TO MAX THE HIGHEST WAVE HEIGHTS AT 16-18 FT.
COORDINATED W/NHC-TPC THIS MORNING ON REMOVING THE MENTION OF THE
SURGE AS WINDS RELAX THIS AFTERNOON. CONDITIONS ARE EXPECTED TO
DROP BACK TO SCA LEVELS TONIGHT. THE DAYCREW HAD THIS HANDLED WELL
AND STAYED CLOSE TO THE WIND/SEAS THAT ARE IN THERE ATTM.
SHORT TERM: SEAS ARE EXPECTED TO REMAIN AT SMALL CRAFT ADVISORY
LEVELS THROUGH LATE WEEK.
&&
.HYDROLOGY...
MAIN STEM RIVERS AND STREAMS WILL SEE SOME SIGNIFICANT RISES W/THE
HEAVY RAINFALL EXPECTED OVER THE NEXT 24-36 HRS. ATTM, 1 TO 3
INCHES STILL LOOKS GOOD FOR A STORM TOTAL RAINFALL BY LATE
WEDNESDAY. SOME AMOUNTS COULD HIT 4 INCHES ESPECIALLY IN THE
UPSLOPE AREAS SUCH AS PENOBSCOT AND PISCATAQUIS COUNTY. THIS HAS
BEEN COORDINATED W/HPC THIS MORNING. WE COULD VERY WELL SEE SOME
SMALLER STREAMS SUCH AS THE BLACK STREAM AND PLEASANT RIVER IN
PISCATAQUIS COUNTY RISING TO NEAR BANKFULL. STANDING WATER WILL BE
AN ISSUE. NERFC DOES HAVE SOME SHARP RISES ON THE MAIN STEM RIVERS
SUCH AS THE PENOBSCOT, MATTAWAMKEAG AND PISCATAQUIS RIVERS. DOVM1
IS SHOWN TO REACH ACTION STAGE LATER TONIGHT AND THEN HOLD IT
THERE INTO WEDNESDAY. ONE THING TO NOTE HERE IS THE POTENTIAL FOR
VERY HEAVY RAIN IN LESS THAN A 6 HRS PERIOD W/ANY TSTMS. THIS
COULD LEAD TO FLASH FLOOD CONCERNS. THE DAYCREW WILL NEED TO
MONITOR THIS CLOSELY TODAY. SOME LIGHTNING STRIKES WERE SHOWING UP
THIS MORNING OVER THE OUTER GULF OF MAINE WATERS.
