Had some decent wind and of course, rain.

The flow off the deck is lacking just a bit as you get into northeast IL (especially around 850 mb) so I wonder if that could explain the lack of tornado reports in that area so far.  Models prog an increase in the LLJ though over the coming hours so assuming the atmosphere hasn't been too worked over, could see another round of severe storms.

Found a way to miss all the tornadoes today lol.  Followed the initial sup that hailed on us here northeastward toward Sterling.  Had some nice downward motion in one of the RFD cuts, and had a nice ragged wall cloud for a bit, but then it crapped the bed.  Broke off that when the new batch of sups went tornado warned back towards home.  Chose the southern one and that one didn't do squat.  Neighbors say that there was a nice rotating wall cloud that passed just east of us, and that went on to produce the brief Morrison tornado.  

Shot this from the front door, brief view of the wall cloud from the first sup, right before the hail began.

Looks like that's verifying.  Can see 5000' (~850) winds increase by ~10KT over the last hour on the KLOT VAD:

Just had a nice cell move through South Bend about 40 minutes ago. Pretty shelf cloud followed by gusty winds, small hail and torrential rains. 

 

 

 

It must have packed a little punch. I just saw this LSR;

SEVERAL LARGE TREES UPROOTED AND TRAILER 
OVERTURNED NEAR INTERSECTION OF MAYFLOWER 
ROAD AND SAMPLE STREET. TIME ESTIMATED FROM 
RADAR.

The wind was really howling as the shelf cloud moved overhead! I hung out in my car in an empty lot away from trees and power lines just in case.

Public Information Statement
National Weather Service Chicago IL
625 PM CDT Sun May 24 2020 /725 PM EDT Sun May 24 2020/

...PRELIMINARY SUMMARY OF THE 5/23/20 SEVERE WEATHER EVENT...

.OVERVIEW...During the afternoon and early evening of Saturday,
May 23, there was scattered severe weather across northern
Illinois and northwest Indiana. Some of the most pronounced
damage was in the far southwest Chicago suburbs occurring in
the mid-afternoon.

.MINOOKA AREA TORNADO...

Rating:                 EF-0
Estimated Peak Wind:    85 mph
Path length /Statute/:  6.3 miles
Path width /Maximum/:   100 yards
Fatalities:             0
Injuries:               1

Start date:             5/23/20
Start time:             2:53 P.M. CDT
Start location:         3 miles west-northwest of Minooka
Start Lat/Lon:          41.4535 / -88.3269

End date:               5/23/20
End time:               3:07 P.M. CDT
End Location:           2.5 miles south of Shorewood
End lat/lon:            41.4800 / -88.2106

SUMMARY: The tornado appeared to develop near I-80 about a
mile west of the Minooka exit. The tornado was likely
responsible for blowing over a car on I-80 resulting in an
injury. The tornado then went on to down at least two wooden
utility poles, about a half dozen large trees, and numerous
large branches. Trained spotter reports helped to further
clarify this was tornado damage. There was also some spotty
wind damage just north of the tornado in a subdivision, and
just south within the town of Minooka.

EF0...Weak......65 to 85 mph
EF1...Weak......86 tO 110 mph
EF2...Strong....111 To 135 mph
EF3...Strong....136 to 165 mph
EF4...Violent...166 To 200 mph
EF5...Violent...>200 mph


.SHOREWOOD THUNDERSTORM DOWNBURST...

Estimated Peak Wind:    75-95 mph
Fatalities:             0
Injuries:               0

Start date:             5/23/20
Start time:             3:04 P.M. CDT

End date:               5/23/20
End time:               3:07 P.M. CDT

SUMMARY: At least two dozen large trees were downed, including
some snapped, in residential Shorewood along and near Seil
Street. This includes large trees down along the DuPage River.
This tree damage was concentrated and intense, with all trees
laying in an easterly direction, evidence for a strong
downburst (microburst).


.JOLIET THUNDERSTORM DOWNBURSTS...

Estimated Peak Wind:    75-95 mph
Fatalities:             0
Injuries:               0

Start date:             5/23/20
Start time:             3:12 P.M. CDT

End date:               5/23/20
End time:               3:28 P.M. CDT

SUMMARY: Many dozen large trees downed across Joliet including
in its downtown. There was also wind damage to multiple roofs
most notably much of the roof lifted off and thrown from a
downtown building. This entire damage area was most likely due
to a series of downbursts given its large footprint, reports
over a fairly lengthy duration, and corroborating radar data as
the organized severe thunderstorms moved through.

NOTE:
The information in this statement is PRELIMINARY and subject to
change pending final review of the event and publication in NWS
Storm Data.

Thank you to our trained storm spotters and Emergency Management
Agency partners for their helpful damage reports.
