A United flight had to return to ORD after flying through a hail core over Lake Michigan. PIREP: ORD UA /OV ORD090035/TM 1925/FL155/TP A320/RM HAIL-CRACKED WIND SHIELD

Few elevated flash/bangs here over the past hour. Severe warning for Lake/Porter Co, IN for hail and psbl winds.
-
"In addition to the polyclonal antibodies, the President has been taking zinc, vitamin D, famotidine, melatonin and a daily aspirin." But where's the hydroxychloroquine?
-
The fact that the hail growth zone (-10C to -30C) is closer to the ground and surface temps aren't all that warm help it reach the ground. Nice forecast profile from the 3km NAM, showing the steep surface to mid-level lapse rates. Not a ton of CAPE but it was obviously more than enough for the heavy showers and isolated storms this afternoon.

Beauties. Had some small hail here shortly before 5.

Obviously smoky in the upper levels today. I guess to many it looks like a veil of cirrus. The sun should have that tell-tale red glow again towards sunset.

2020 Record Hot/Warm Summer For Chicago
purduewx80 replied to Chicago Storm's topic in Lakes/Ohio Valley
meh. chicago will continue to expand into the burbs, and the burbs will continue to expand. it's not like UHI warming is fake - we all feel it. -
Think there is at least a marginal risk for severe hail across the region overnight as the 850 warm front lifts into northern IL. Mid-level flow is strongest near and north of the IL/WI border. Lapse rates are steep and there is a decent amount of both directional and speed shear such that some transient supercell structures are probable. 12Z NAM for ORD valid at 09Z below:

it's incredibly sad you still believe this.
-
Nice expansion of the CDO over the past hour and a warm spot (psbl eye) in the middle.
-
wake me up when your at-risk kid catches it and you're still downplaying everything.

Initial estimates of crop damage alone are $3.4 billion. Who'd have thought an August derecho would be on 2020's list of billion dollar disasters?

I love these:

HRRR and HRRRx did well, as did the RPM (IBM/WSI's ARW), IBM GRAF and the hi-res Canadian (HRDPS).

LOT just issued a high wind warning for the back side.
-
DPA gusting to 60MPH now behind the line.
-
Now 72 MPH
-
Spotter report of golf-ball sized hail in the line near Plainfield. Almost hard to believe, but if true, extra damaging when associated with severe winds.

One of those microscale circulations is just west of KLOT radar, which is estimating 100-105MPH winds 500' above the ground, so likely reaching the surface. KLOT will probably go down if it holds together.
-
Unrelated, but there is a large fire in Franklin Park. The smoke plume shows up on radar over O'Hare.
-
strongest winds on the leading edge are associated with microscale bows and are more isolated. note the stronger/longer duration winds are associated with lighter precip, indicative of the downward motion associated with the descending rear inflow jet (blue areas in velocity on the right-most image).

Other way around
