Chicago Storm

Worst and most significant/widespread flooding I have experienced here is ongoing. Most roads are several blocks in which they are partially to fully underwater, many with feet of standing or flowing water...with many closed. The nearby creek flooded a large park complex, which has backed up onto a nearby road. There is one stretch of a nearby road where several blocks are under feet of water, with cars submerged to above their windows and water is entering homes. Up until now the period of tropical remnants of Sept 2008 featured the worst flooding I had seen around here, but this has now topped that. In that case it was 10"+ of rain over a longer span of time, where this was 4"+ of rain in the past 24hrs...and nearly 2"/hr at one point tonight.

~2" of rain at ORD in the past hour.

Still one well pronounced couplet as it is about to enter Kane Co. Looks like on the current track, it will come about 15min driving distance from here. If it holds on a bit longer, might have to take a drive.

New tor warning with it, as there are still two couplets as it moves across DeKalb Co.

There it is... tor warned.

Storm needs a tor warning. Two couplets in Lee Co currently, and becoming better defined with closer approach to radar.

There has been a significant meso with the storm moving across Lee Co, with associated WAA wing extending eastward into the Chicago metro.

FFW for Chicago... ~1" of rain in 10min at MDW COOP.

Best looking radar around here in ages.

Might have said this too soon...We'll see.

Main issue is no surface flow. Probably would have produced otherwise.

Can probably toss this now for the most part. Looks like any training with excessive totals will now be more isolated/localized...instead of more widespread as it looked earlier.

The whole area has the same kind of threat...No matter if you're in ORD, IKK or GBG.

While there is a still a SLGT worthy severe risk for the area (even if SPC did trim it, they have been meh), the flood threat looks to steal the show overall. Upwards of 1.00-2.50" of rain fell across a corridor within N Illinois last night/this morning. It looks like a good portion of that corridor will overlap with the heaviest for this afternoon/tonight, with upwards of another 2-5" of rain possible. Could be seeing final totals in that overlap region in excess of 6"...if things line up correctly.

Quality storms this morning around here. 1.28” rain at ORD this morning and 2.04” here. .

It is definitely much better, as madwx pointed out. Not just for our region either...It has done well in the Plains as well. A recent example was when it nailed the 5/7 event from 1+ day out.

It is. Previous high was <180.

Tomorrow definitely holds potential, but all hinges on tonight/tomorrow mornings activity. SGT risk looks good for now, but could need upgrade to ENH in the morning once everything becomes clear.

Local threat possible on Thursday.

But also had the highest test count as well, around 30k.

These are significant... 0140 PM TSTM WND DMG 2 E FORT WAYNE 41.07N 85.10W 05/10/2020 ALLEN IN PUBLIC WIRES DOWNED, TREES INTO HOUSES. PRIMARILY EAST SIDE OF FORT WAYNE INTO NEW HAVEN. 0210 PM TSTM WND DMG 1 S FORT WAYNE 41.05N 85.14W 05/10/2020 ALLEN IN AMATEUR RADIO 15-20 FOOT TREE DOWNED AT ARCADIA CT. AND HOAGLAND AVE. TREE PARTIALLY BLOCKING ARCARDIA CT.

Several damage reports down that way as well, so seems valid.

FWA G78MPH with that line of weak convection moving through.

Just like that high of 70 on April 25th was gonna be the last 70+ day of April...only to hit 76 three days later, on the 28th. .

Protests over the stay at home order starting up downtown today.
