11:15 p.m.

Severe weather today has either been southwest & south (earlier line) or north (this evening-tonight band/line) of us.

A kids learning center was severely damaged by a tornado near South Bend.  Other businesses & structures sustained damage.  Tree damage was reported from Marshall County, Indiana.

There is a quite extensive wind damage from Indy metro & southwest & southward.  A dump truck was tipped over in Monroe County, Indiana with a nearby pole barn completely destroyed.  Widespread tree damage (& some structural damage) was reported across Greene & Clay, Martin & northern Pike counties.  Even areas south-southeast of Danville, Illinois saw wind damage.

As to why the first line did not congeal completely in our area & there was a break is a bit of a mystery.  It may be partially due to an area of low clouds surging northward out ahead of the line trying to develop toward our area, which disrupted the formation. 

As to why we did not receive severe like they did north of us this evening, it was due to too much initial rainfall ahead of the developing line/band.

Tonight, we still have rainfall & some storms in the area.  Some places in this band/line have received 1 to +2" of rainfall this evening. 2.40" of rainfall was measured at the official USGS rain gage at Covington.  Southside of Lafayette measured up to 1.50", while the Purdue Airport saw 1.17".  1.20" was reported from near Brook for today's total. 

It will exit soon, followed by patchy fog & a few lingering showers overnight.

Showers are possible Monday morning, followed by sun & some scattered afternoon storms as a couple of broken lines may pass with isolated severe weather possible.

Highs today ran 81-87 with peak dew points of 71-77.

Highs mid to late week to next weekend will reach 89-93 with heat indices of 97-110 with dew points in the 70s.

Tuesday-Wednesday look dry with potentially an MCS Wednesday night-Thursday.

Friday through next weekend looks hot & dry with only a couple isolated storms possible right now.  Stay tuned for tweaks to that forecast.


8:30 p.m.

Line/band of rain & some storms continues to congeal & move northeastward.

The risk of an isolated severe storm or two is there with locally-heavy rainfall.

NAM model is over-doing the storm intensity for this evening, but still shows the trend of the band/line coming through & it getting out of here before midnight.  It also shows the accurate positioning of the MCV well as you can see the comma head pivot through northern Indiana at the end of the loop.


7:32 p.m.

Showers & storms are popping in parts of the viewing area & are organizing southwest of us as MCV pivots toward our area.

These are all trying to form a line as they move northeastward toward & through the area.

Meanwhile, nasty bow of severe storms is raking western Kentucky & Tennessee.  Significant wind damage (possibly tornadic) has been reported in southeastern Missouri & western Kentucky.

As for us, SPC continues SLIGHT RISK for severe in the area & then southward through Kentucky.  Band of ENHANCED-type parameters exist for storms over Kentucky & into Tennessee, meanwhile here it is more MARGINAL.

Risk of an isolated severe storm or two seems reasonable through evening as this line lifts through the area with this MCV. 

The better lift & instability form storms is just south of our area & may move into our area for a while as this passes this evening.


5:20 p.m.

Indy metro & southward has seen wind damage from first MCV-induced wave of storms.

Watch cancelled early, but still watching MCV in south-central Illinois, as first one departs.

Skies are clearing & narrow corridor of heating & destabilization is underway in our area & in Illinois.

HRRR model is on-board with some more storms this evening with second MCV pivoting through area.

Some severe weather is possible.


3:51 p.m.

Wind damage has been reported over southwestern & south-central Indiana.  Wind damage reports are also beginning to come in from Indy metro.

Wind damage was reported near Danville, Illinois, as well.

Line is in two pieces:  one southeast of our area & one over our northwestern half.

Wind gusts have been measured from the storms of up to 37 mph in Benton & southern Jasper counties.  Kentland Airport gusted to 34 mph, Round Grove 35 mph, Fowler 37 mph.  Storms may organize & pose a severe gust threat over northern White, eastern Jasper & Pulaski counties over the next hour.  These appears to be occurring just east of the MCV center.

Rainfall has been brief, but torrential.  A quick 0.95" was measured south of Earl Park, 0.67" (& still pouring) at Brook & 0.51" between Fowler & Round Grove.

Also line of storms racing northeastward may arc back some torward eastern Clinton & over Howard to southern Miami counties over the next 1-2 hours with wind risk.

In-between Lafayette & Lebanon, where break resides, we will see if anything can fill in.

However, there is another MCV that is evident near St. Louis.

There are some indications that this may bring another wave of storms into the this evening as we re-charge with instability behind this first round.

These would roll up from the west & southwest into the area with some severe risk.

Watch is up until 8 p.m.


2:30 p.m.

Severe T'Storm Watch is up for a good chunk of the viewing area.

Line of storms continues to develop (with one bow already in southwest Indiana) & move northeastward as MCV over Illinois pivots northeastward.

Main threat from storms here this afternoon is wind.  Water loading & dry layer at 850-750 mb supports potential of a couple wet downbursts.

However, any storms that remain more discrete could produce large hail.

SPC did end up expanding SLIGHT RISK to cover much of the viewing area.

Even if you are not in the watch be aware that you could still see some severe weather.
