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

Pittsburgh, PA (KPIT), launched 12:00Z, 10.3 hours before the alert went out and 169 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, Apr 12, 3:18 PM EDT, 2 hours 59 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OHIO
318 PM EDT WED APR 12 2006

.SHORT TERM (TONIGHT THRU FRIDAY NIGHT)...
WILL MONITOR SHOWER/TSTORM THREAT LATE THIS AFTRN INTO THIS EVENING.
DRIER CAPPED AIR SWEEPING IN FROM SW BUT UPPER LOW JUST PASSING
NORTH OF LAKE ERIE THIS EVENING AND SOME SHOWERS/STORMS WILL LIKELY
SPRIAL SOUTH AND CATCH NE OH/NW PA BEFORE DRY AIR SPREADS ACROSS
TNGT. INSTABILITY WILL BE ENUF THAT STORMS COULD HAVE WIND/HAIL AND
INDIVIDUAL STORMS COULD EVEN BE ROTATING CLOSER TO UPPER LOW. WILL
PROBABLY HAVE TO USE LEFTOVER WX N CENTRAL OHIO AND HAVE CHC POPS E
OF CLE EARLY TNGT THEN DRY LATER TNGT. SHOULD BE A NICE DAY TOMORROW
WITH WARM TEMPS EXCEPT LAKESHORE EAST OF CLEVELAND WHERE WIND WILL
COME IN OFF THE LAKE.

VARIETY OF SOLUTIONS FOR THURSDAY NIGHT INTO FRIDAY. ALL MODELS
DEVELOP TSTORMS NEAR THE EXIT REGION OF LOW LEVEL JET AND THUERMAL
RIDGE OVER UPPER MIDWEST WHICH SEEMS VERY REASONABLE. WHERE THE
STORMS TRACK ARE THE PROBLEM. THEY SHOULD SLIDE SE ALONG THERMAL
FIELD WHICH IS DIRECTLY ACROSS FCST AREA. GFS SEEMS TOO FAR NORTH
WHILE NAM LOOKS BETTER ON POSITION. WRF LOOKS MORE LIKE THE NGM A
BIT SLOWER AND DIRECTLY OVER NOTHERN OHIO. MODELS HAVE LOOKED THIS
WAY FOR SEVERAL RUNS NOW AND WILL USE LIKELY POPS FRIDAY NGT.
BOUNDARY SET DOWN BUT THIS TYPE OF EVENT TYPICALLY PUSHES SOUTH AND
INDEED NAM AND GFS REDEVELOPS NEW ACTIVITY SOUTH OF FCST AREA ON
FRIDAY WHILE SLOWER WRF TAKES UNTIL LATE AFTERNOON TO CLEAR THE
AREA. GFS POPS DROP OFF DRAMTICALLY IN THE AFTERNOON AND HAVE A
FEELING THIS IS THE BETTER IDEA BUT DO NOT HAVE ENOUGH CONFIDENCE AT
THIS POINT TO TRY AND SPECIFICALLY TIME ACTIVITY ON FRIDAY ALTHOUGH
I WILL USE WORDING MAINLY IN THE MORNING IN ZONE FCST. NAM POSTS
HIGH CAPE ACROSS SOUTHERN PART OF FCST AREA FRI AFTRN WHILE GFS
FARTHER SOUTH TOWARD OHIO RIVER. NOT SURE IF ANY NEW ACTIVITY CAN
REDEVELOP BACK NORTH FRIDAY NIGHT INTO SATURDAY AS RIDGING INCREASES
ALOFT AND WILL USE LOWER POPS (30 FRIDAY NIGHT).

WIND PROGGED TO BCM LGT TNGT AND SOME RADIATIONAL COOLING PSBL LATER
TNGT INLAND SITES SO WILL FCST NEAR LWR TEMP GUIDANCE TNGT...
GENERALLY 45-50. GFS TEMP GUIDANCE LOOKS OK THURS EXCEPT PERHAPS A
DEGREE OR TWO COOLER AT ERIE. PROABABLY HAVE A NORTH WIND FOR A
WHILE ON FRIDAY BEHIND TSTORM COMPLEX BUT ASSUMING SOME SUNSHINE
BREAKS THROUGH TEMPS SHOULD RECOVER SOMEWHAT SO WILL FCST 50S AT
IMMEDIATE LAKESHORE TO LWR/MID 70S WELL INLAND.

&&

.LONG TERM (FRI NIGHT THRU WED)...
NOT SURE ABOUT THREAT OF CONVECTION SATURDAY. BEST INSTABILITY WILL
BE SHIFTING BACK NORTH ACRCOSS FCST AREA BUT RIDGING ALOFT WILL
INCREASE. WILL USE LOW POP (SLIGHT CHANCE) AND NOT MENTION IT IN
ZONE FCST AT THIS TIME.

SITUATION FOR EASTER SUNDAY STILL LOOKS IN QUESTION. MODELS CONTINUE
TO WEAKEN THE SURFACE LOW AS IT COMES EAST INTO THE DEVELOPING
BLOCK. GFS BRINGS LOW DIRECTLY ACROSS FCST AREA WHILE ECMWF FARTHER
SOUTH AND WEST ON SUNDAY. CANADIAN MODEL LOOKS MORE LIKE THE ECMWF.
NCEP HAS HIGHEST POPS NW OF THE FCST AREA WHICH DOES NOT MATCH WELL
WITH OTHER MODELS OR EVEN THE ENSEMBLE POPS. WILL MENTION A GENERIC
CHANCE OF SHOWERS/TSTORMS FOR ENTIRE FCST AREA AT THIS TIME WITH NO
TIMING. LOOKS LIKE RAIN THREAT SHOULD SAG SOUTH AS HIGH PRESSURE
BUILDS ACROSS E CANADA EARLY NEXT WEEK AND WILL TREND FCST DRY AND A
BIT COOLER. NEXT CHANCE OF RAIN FROM THE WEST TUE NGT INTO WEDNESDAY
ALTHOUGH TIMING AGAIN UNCERTAIN BECAUSE OF BLOCKING PATTERN.

TEMPS OF COURSE DEPEND ON WIND DIRECTION AND AMOUNT OF CLOUDS
ESPECIALLY ON EASTER. IF WORST CASE SCENARIO DEVELOPS... COULD
DEVELOP A CHILLY RAIN...BUT IF SHOWERS HOLD OFF MAY BE MILD. COOLER
EARLY NEXT WEEK BUT NOT STILL NEAR NORMAL EXCEPT CHILLY ON MONDAY
NEAR LAKE ERIE. COOLER AIR POISED TO FILER IN MIDWEEK AFTER NEXT
FRONT BUT MAYBE NOT UNTIL 8TH DAY (THURSDAY).

&&

.AVIATION(18Z-18Z)...
CURRENTLY...LINE OF SHOWERS WITH EMBEDDED THUNDERSTORMS MOVING
ACROSS EASTERN AREAS AT THIS TIME. IN SHORT TERM...MENTIONED SOME
VCTS FOR YNG WITH THIS LINE APPROACHING. EXPECTING SOME SHOWERS
ACROSS ERI OVER THE NEXT HOUR ALSO.

LOW PRESSURE RESPONSIBLE FOR WEATHER ACROSS AREA CURRENTLY LOCATED
OVER MI. WATER VAPOR AND VIS SAT CURRENTLY WELL DEPICTING VORT MAX
SWINGING THROUGH SRN MI AT THIS TIME. BOTH RUC AND NAM SHOWING THIS
VORT MAX SWING ENE THROUGH SRN MI AND INTO CANADA NORTH OF LAKE ERIE
THIS EVENING. LOOKS LIKE COLD FRONT BEGINS TO SWING THROUGH NRN OHIO
LATER THIS AFTN AND EVENING. BIG CONTEMPLATION WAS THUNDERSTORM
ACTIVITY THAT CAN DEVELOP OVER THE NEXT SEVERAL HOURS INTO THIS
EVENING. GUIDANCE INDICATING AND INCREASE IN INSTABILITY ACROSS THE
AREA AS DEWPOINTS AND TEMPERATURES RISE THROUGH THE AFTERNOON. VIS
SAT SHOWING AN INCREASED AREA OF CU DEVELOPING ACROSS INDIANA AT
THIS TIME.

THEREFORE...WITH GIVEN FACTORS MENTIONED ABOVE MAINTAINED MENTION OF
THUNDERSTORMS IN TAFS THROUGH THE LATE AFTERNOON AND EVENING HOURS
FOR ALL SITES. ALSO...ANOTHER ISSUE THROUGH THE REMAINDER OF
AFTERNOON AND EVENING WILL BE GUSTY S-SW WINDS ACROSS ALL SITES.
MANY LOCATIONS GUSTING BETWEEN 20-30KT ACROSS OH AND IN AT THIS
TIME. EXPECTING THIS TO CONTINUE THROUGH EVENING AHEAD OF COLD
FRONT. CONDITIONS WILL IMPROVE OVERNIGHT FROM WEST TO EAST ACROSS
AREA...AND WINDS WILL SUBSIDE BY 12Z THU FOR ALL SITES.
