A band, a bow in the far south & a southern half supercell produced severe weather 7-8:30 p.m.
Temperatures reached 75-83 during the day, but dew points dropped to the 30s to 50 prior to the storms.
With steep lapse rates with the cold air aloft, strong wind fields & shear & upper trough (& very sharp height falls & sharp surface cold front), storms blossomed with high bases due to the dry, dry air near the surface. Such a scenario is more common in the drier High Plains from western Texas & Oklahoma to eastern Montana & North Dakota than here.
Very strong to severe gusts reached the surface with the rainfall & t'storms due to the dry air.
Some minor damage to rooftops & trees occurred.
The strongest wind gust in the area was measured near Thorntown with a measured gust of 75 mph with shingle & tree damage. Trees & powerlines were reported down across Carroll County. One tree fell over a drive way near Battle Ground. A large limb fell from a tree at Otterbein. Multiple power outages occurred in the area.
Hail covered the ground like snow in a discontinuous band from West Lebanon to north of Darlington.
Hail up to 1-1.50" occurred in this band.
The intensity of the storms & damage increased south & southeast of our area as dew points rose (along with more surface CAPE), but our dry surface & low levels wedged a few thousand feet up in those areas. This enhanced gusts, which reached near 90 mph in places. Shear & higher CAPE near/at the surface also produced one tornado (EF1 southwest of Indianapolis).
W = wind damage or measured gust 58 mph or greater
H = hail 1" in diameter or larger
T = Tornado
Measured t'Storm gusts that reached or exceeded 45 mph (I did include 60 mph Purdue Airport gust & our 54 mph gust as it occurred during rain & thunder. I think the 60 mph gust in NWS LSR was labeled "Non-T'Storm Wind Gust":
