What was reported inside it

Time	Report	Where	Remark
May 7, 7:40 PM EDT	HAIL 0.25	1 N Ripley, IN

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.

.SHORT TERM...LATE THIS AFTERNOON THROUGH SUNDAY NIGHT

19Z SFC ANALYSIS REVEALS A WEAK SFC LOW NEAR DAVENPORT IOWA...WITH A
STATIONARY FRONT EXTENDING EWD INTO OUR FAR SW. THE PRIMARY FEATURE
OF INTEREST ALOFT IS A SOMEWHAT SHEARED OUT MID LVL VORTICITY
MAXIMUM INVOF OF EASTERN IA/SOUTHWEST WI. MODEST LARGE SCALE
ASCENT...PER Q-VECTOR PROGS...AND ISENTROPIC LIFT WITH REDUCED CPD/S
NE OF THE STATIONARY BOUNDARY HAVE BEEN SUPPORTIVE OF SCATTERED
SHOWERS ACROSS MUCH OF THE CWA. OVER THE LAST HOUR AND A HALF MORE
ORGANIZED SHOWER AND ELEVATED THUNDERSTORM ACTIVITY HAS DEVELOPED
JUST NE OF THE SFC BOUNDARY CLOSER TO THE 85H FRONT. STEEP MID LEVEL
LAPSE RATES MAY ALLOW FOR PEA SIZE HAIL FROM SOME OF THE MORE
IMPRESSIVE CORES ALONG THIS INITIAL LINE. EXPECT THIS SHOWER AND
STORM ACTIVITY TO CONTINUE NEWD LATE THIS AFTERNOON...WEAKENING A
BIT AS IT SHIFTS INTO MORE STABLE AIR. ATTENTION THEN TURNS UPSTREAM
ACROSS CENTRAL IL WHERE SIGNIFICANT BREAKS IN CLOUD COVER AND SFC
DEWPOINTS IN THE MID/UPPER 50S HAS ALLOWED FOR AN ENVIRONMENT
CONDUCIVE FOR CONVECTIVE DEVELOPMENT. THIS COMBINED WITH ADDED LOW
LEVEL CONVERGENCE NEAR THE SFC LOW/FRONT...A FAVORABLE SHEAR
PROFILE...AND STEEP MID LVL LAPSE RATES SUPPORT AN ISOLATED SEVERE
THREAT. WEAK CAP CURRENTLY IN THE PROCESS OF BREAKING...WITH
ANOTHER ROUND OF SHOWERS/STORMS LIKELY TO WORK EWD INTO WEST-CENTRAL
INDIANA BTW 22-02Z. THIS ACTIVITY MAY BYPASS THE FA JUST TO THE
SOUTH...BUT DID MENTION THE POSSIBILITY OF AN ISOLATED SEVERE
THUNDERSTORM FOR OUR FAR SW IN THE HWO. ALSO CONTINUED WITH CHC
POPS...HIGHEST SOUTH...00-03Z GIVEN THE POTENTIAL MISS TO THE SOUTH.
ANY MID/UPPER LEVEL SUPPORT WILL EXIT TO THE EAST LATER THIS
EVENING...WITH ANY LINGERING SHOWERS MAINLY CONFINED TO SOUTHERN
PORTIONS OF THE FA NEAR THE SINKING SFC LOW/FRONT.

HEIGHT RISES AND LARGE SCALE SUBSIDENCE WILL SUPPORT DRY WX LATER
TONIGHT THROUGH SUNDAY NIGHT. ANY LINGERING STRATUS AND DRIZZLE
SUNDAY MORNING...ESPECIALLY ACROSS THE SOUTHEAST...WILL MIX OUT TO
SCT/BKN CU PER CU RULE AND NAM/GFS SOUNDING PROGS. DEEPER MIXING AND
LESS CLOUD COVER ON SUNDAY WILL ALLOW FOR WARMER TEMPS...WITH HIGHS
GENERALLY REACHING NEAR 70F. BACKGROUND EASTERLY LOW LEVEL SYNOPTIC
FLOW SHOULD EVEN LIMIT THE EWD PUSH OF THE LAKE BREEZE ALLOWING
AREAS FROM MICHIGAN CITY TO BENTON HARBOR TO REACH TO NEAR 70F.
MODELS ARE STILL CONSISTENT IN EJECTING A LEAD SHORTWAVE INTO THE
CENTRAL CONUS MONDAY NIGHT...AHEAD OF DIGGING DEEP UPPER TROUGH
ACROSS THE WESTERN CONUS. THE RESULTING LOW LEVEL RESPONSE ACROSS
THE PLAINS WILL LIKELY SUPPORT CONVECTION NEAR A DEVELOPING WARM
FRONT. ATTM...IT APPEARS AS IF THIS ACTIVITY SHOULD REMAIN WELL WEST
OF THE FA THROUGH 12Z MONDAY WITH JUST SOME INCREASING MID/UPPER
LEVEL CLOUDINESS LOCALLY.
