What was reported inside it

Time	Report	Where	Remark
May 27, 4:20 PM EDT	HAIL 0.88	Franklin Furnace, OH	VIA EMA

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Cncnati-Daytn, OH (KILN), launched 12:00Z, 8.2 hours before the alert went out and 125 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.

NWS Wilmington, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at May 27, 3:53 PM EDT, 16 minutes earlier.

Area forecast discussion, May 27, 3:53 PM EDT, 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
353 PM EDT TUE MAY 27 2014

.SYNOPSIS...
AN EAST-WEST ORIENTED FRONTAL BOUNDARY WILL BE THE FOCUS FOR
THUNDERSTORM DEVELOPMENT TONIGHT THROUGH THURSDAY. DRY WEATHER IS
EXPECTED FOR THE WEEKEND WHEN HIGH PRESSURE IS FORECAST TO BUILD
IN AT THE SURFACE AND ALOFT.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
NUMEROUS THUNDERSTORMS HAVE DEVELOPED IN AN UNSTABLE AIRMASS...
MAINLY SOUTHEAST OF I-71. HARD TO PINPOINT CAUSE OF CONVECTION IN
AN ENVIRONMENT OF WEAK FORCING. CONVECTION APPEARS TO BE DRIVEN BY
DAYTIME HEATING THAT IS PRODUCING UP TO 3000 J/KG CAPE...WITH AN
ASSIST BY SOME SYNOPTIC SCALE LIFT PROVIDED BY A VORT MAX OVER
EASTERN OHIO. LOOKS LIKE MOST OF THE ACTIVITY WILL MOVE EAST AND
DIMINISH THIS EVENING AS INSTABILITY WANES AND THE VORT MAX MOVES
FARTHER EAST. THUNDERSTORM STRENGTH HAS BEEN LIMITED BY RATHER
WEAK WIND FIELDS...THOUGH SOME OF THE STRONGER CELLS HAVE
PRODUCED PENNY SIZED HAIL AND 40 MPH WIND GUSTS.

CONVECTIVE DEVELOPMENT MAY INCREASE AGAIN LATER TONIGHT AS A WEAK
FRONT DROPS SOUTH FROM THE GREAT LAKES TOWARD NORTHERN COUNTIES.
LOWS IN THE 60S ARE FORECAST FOR TONIGHT.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
THUNDERSTORMS WILL BECOME LIKELY ON WEDNESDAY WHEN THE EAST-WEST
ORIENTED FRONTAL BOUNDARY WILL BE DROPPING SOUTH ACROSS THE AREA.
DUE TO RATHER WEAK WINDS...WIDESPREAD SEVERE THUNDERSTORMS ARE NOT
EXPECTED. HOWEVER...THE WEAK WINDS ALONG THE SLOW MOVING BOUNDARY
MAY ALLOW FOR SLOW MOVING THUNDERSTORMS TO PRODUCE HEAVY DOWNPOURS
RESULTING IN MINOR FLOODING.

THUNDERSTORM CHANCES WILL DIMINISH BUT NOT END WEDNESDAY NIGHT AS
THE BOUNDARY STALLS NEAR THE OHIO RIVER IN AN ENVIRONMENT OF
DECREASING INSTABILITY WITH LOSS OF DAYTIME HEATING.

TEMPERATURES WILL BE SUPPRESSED A BIT BY CLOUDS AND PRECIP...WITH
HIGHS EXPECTED TO BE IN THE LOWER 80S.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
A WEAK BOUNDARY ALONG THE OHIO RIVER WILL MOVE SOUTHWARD THURSDAY
MORNING. HIGH PRESSURE BUILDING OVER THE GREAT LAKES REGION WILL
PUSH N TO NE WINDS THROUGH OHIO TOWARDS THE FRONT. THE CONVERGENT
WINDS WILL INTERACT WITH THE BOUNDARY TO INCREASE THE CHANCE FOR
SHOWERS LATE THURSDAY MORNING AND EARLY AFTERNOON. PREVIOUS FORECAST
WAS IN EXCELLENT SHAPE SO I MAINLY PUSHED THE TIMING UP BY 2 HOURS
TO MAKE SURE THAT THERE WAS NO STORMS OVER CWA WORKING INTO THE
EVENING.

NORTH WINDS WILL TURN EAST BY SATURDAY AS THE SURFACE HIGH SETTLES
OVER THE CANADA/US BORDER AND NOSES INTO THE NORTHEASTERN OHIO
VALLEY. FLOW DOES NOT TURN SOUTH UNTIL LATER SUNDAY AND WILL THEN
MARK A RETURN TO WARMER AND MORE MOIST AIR. THE NEXT THREAT FOR RAIN
WILL OCCUR MONDAY AS THE SOUTHWEST WINDS PUSH MORE MOIST AIR INTO
THE REGION AND CONTINUE THROUGH NEXT WEEK. AN EVER-INCREASING THREAT
FOR SHOWERS AND THUNDERSTORMS WILL INCREASE WITH THE TEMPERATURES
AND MOISTURE FOR NEXT WEEK.

TEMPERATURES WILL GENERALLY BE IN THE UPPER 70S TO LOWER 80S THROUGH
THE PERIOD WITH SEASONABLY COOL OVERNIGHT LOWS IN THE 50S.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
SCATTERED THUNDERSTORMS HAVE DEVELOPED ACRS SRN OHIO/NRN KY
AROUND THE PERIPHERY OF A MID/UPR LEVEL TROF. AXIS OF THESE
STORMS WILL PIVOT EAST THRU THE AFTN AND WILL DISSIPATE WITH SUNSET
DUE TO THE DIURNAL NATURE. EXPECT HIGH/MID CLOUDS TO PERSIST
OVERNIGHT. WITH PLENTY OF LOW LEVEL MOISTURE IT DOES APPEARS THAT
MVFR VISIBILITIES WILL BECOME PREVALENT LATE TONIGHT WITH SOME
LOCATIONS POSSIBLY GETTING DOWN TO IFR. SOUTHWEST WINDS DURING THE
DAY MAY GUST UP TO 20 KTS.

OUTLOOK...MVFR VISIBILITIES POSSIBLE WEDNESDAY NIGHT/THURSDAY
MORNING. THUNDERSTORMS ARE POSSIBLE WEDNESDAY AND THURSDAY.

&&

.ILN WATCHES/WARNINGS/ADVISORIES...
OH...NONE.
KY...NONE.
IN...NONE.
