CVG reporting 0.13" with the first batch. Saw a couple reports of 1" diameter hail in Burlington KY.
There goes Les's vegetable garden
I'll be home Sunday to survey the damage lol

New Madison, OH in Darke County - half inch diameter hail reported.
Hi Mike,
I'm kind of surprised that hail report from New Madison hasn't shown up in the SPC storm reports.
Never mind as the reason could be half inch sized (mothball sized i.e.) doesn't meet severe criteria.

You'd think ILN would have picked a different day to change the picture tube on their radar other than the only day all year for severe weather

Looks like round 2 is initiating already up in northern Indiana near Lafayette. SPC meso-analysis showing 4500 J/kg CAPE across central Indiana now. Mercy sakes! Supercell composite near those storms is 12 and we have 45-50 kt shear right over us now. Its about to pop!
Precipitable water - looks like we have the highest around with about 1.7".

Severe threat has definitely shifted S/SW , more from Hillsboro, west and southwest to just north of Lou. Ingredients coming together quickly for AVland

That reading seems a little suspect to me. Not saying it isn't correct, but I can't find any other stations in the region above the lower 90's.

Maybe a plane took off and fried the sensor!

High to extreme levels of CAPE are sliding in as CIN from the earlier action begins to erode. Wowzers.

STP is starting to rise as well. Damaging winds are of course the main threat, but we really need to watch things progress as the tornado threat is also increasing. Probably have a tornado watch issued for most within the next few hours.

60% chance of Severe watch....

Mesoscale Discussion 0996
NWS Storm Prediction Center Norman OK
0237 PM CDT Fri Jun 18 2021
Areas affected...Central IN into Western OH
Concerning...Severe potential...Watch possible
Valid 181937Z - 182100Z
Probability of Watch Issuance...60 percent
SUMMARY...Evolution of ongoing storms remains uncertain, but the
severe threat may increase through the afternoon. Watch issuance is
possible by 20Z.
DISCUSSION...An apparent elevated supercell has gradually evolved
from ongoing elevated convection across northern IN, with convection
increasing into northeast IN, and also further south into more of
central IN. Large-scale ascent remains rather subtle, though some
mid/upper-level support is possibly being provided by an MCV moving
across portions of IL.
As MLCINH continues to weaken across the area, the concern is for
increasingly surface-based convection to develop, especially from
far eastern IN into western OH, where relatively backed low-level
flow would support some tornado threat, in addition to the threats
of hail/wind. While the evolution of ongoing storms remains
uncertain, watch issuance may be required by 20Z to address the
threat of surface-based storms with all hazards possible

Yeah they’re probably going to issue a tornado watch for areas north of the metro at some point then probably watches further south later.
