this summer has already been an A+ in my book (frequent garden variety storms + a ton of low-mid 70 perfect days) but it's nice to have some deep summer days mixed in...mulitple rounds of storm in the region for 3-5 days in a row. Tonight looks good again as done the Sunday evening lake play

That may or may not cause some issues... yeesh.  :yikes:

 

Some impressive pictures should start rolling in here soon with daylight.

 

Yeah, I'm seeing some on the news right now. Deep deep water, where it shouldn't be. 

 

Nothing crazy here...but a decent spread from west to east in the LAF area. Past 24 hour totals.

 

0.42" - West Lafayette 4.9 W (thru 7:00AM)

0.54" - LAF (thru 8:00AM)

1.10" - Lafayette 2.2 S (thru 7:00AM)

1.38" - Lafayette 2.2 NE (thru 7:00AM)

2.27" - West Lafayette 2.8 NNE (thru 7:30AM)

a river crest on the East Branch DuPage is expected to reach a top 10 (not sure how far back the historical records go back) height here locally in Bolingbrook later today...

 

Quite a few school closings in the areas Steve highlighted earlier in the morning in the Chicago area....

 

Helicopter shots still show many urban areas with standing water and stranded cars...

Someone correct me if I am wrong, but looking at Purdue's Climate page, the 10.63" in Hartford City should set a new 24 hour rainfall record. The previous one being 10.5 in Princeton in 1905. 

 

https://climate.agry.purdue.edu/climate/facts.asp

 

IND confirms the event on their 20th Century Weather Highlights.

 

1905...MAXIMUM 24 HOUR RAINFALL IN INDIANA 10.50 INCHES ON AUGUST 6 AT PRINCETON.

 

Will have to dig to confirm with other offices...

 

Edit: see if the link works now... Thanks Jonger!

Truly amazing out of Hartford City.  My wife's Mom lives there...the flooding is unheard of, in places that would never have it.  My MIL's house, which is not in a shallow or low area is completely flooded.  The entire first floor of her house is flooded up to the cushions on her couches.  The hospital is completely closed off also....with what appears more on the way out W/WNW

Anyone know what the protocol is in situations like this (potential new state record)?  Are tests performed to make sure the equipment is accurate?

I was actually wondering the same thing when I realized it may set a new record. My theory (and totally my own) is that the office would simply take word from the cocorahs and determine the validity from there. Since this particular report was from cocorahs, and looking at their website, cocorahs requires a 4" rain gauge which measures a full 11" of rain. It will be interesting to see if they accept the total. If anything, they could always ask the observer to take a picture and send it to their office if they were concerned.

12z NAM says we do it again tonight along the front. The PWATS are collectively enhanced but you get the idea. 

 

Will be curious to watch how we recover. NAM progs 4000 j/kg of MUCAPE at 0z here. 

 

cloud cover is thinning rapidly, instability shouldn't be much of an issue naso sure about forcing
