Chicago Storm

ORD was still at 80 as of the 1AM OBS last night, before showers and storms moved through with the front. .

nice seidel overplaying there.

when's the storm gonna hit?

josh is chasin' the wrong storm.

Shear is definitely still an issue, in addition to some dry air entertainment too as seen on WV.

Looking at satellite, there appears to be some southerly shear still affecting the storm. Outflow is a bit restricted on the south side of the storm, with the southerly shear evident to the south as well. This seems to have been a problem for the past 24-36hrs.

he’s been putting out the goods. .

could have something in common...failure. especially when it landfalls as a cat 1 in sc after meandering offshore for days.

comparing anything to ohio is p bad.

CDO is once again fairly lopsided, with cloud tops on the western side showing steady warming. Shear is definitely still an issue.

figured there was a reason behind you being so quiet. at least he's chasing one of the two.

well played.

oh no

you're right actually. you were just handled decently.

i blame vortmax. i didn't even know storm2k even still existed.

p much. or how to compare current vs previous model runs correctly.

Can't wait for Irma.

Two things...Insane Plains-like mixing, and drier conditions recently. 0z ILX sounding from this evening shows mixing to ~600mb. Also that East-Central IL area on south to the Ohio River area has been drier than surrounding areas the past month.

91 ORD and 92 MDW.

Still 80 at ORD after 1AM. .

92 ORD and 93 MDW today.

Interesting day today... Several storms exhibited rotation an couplets across the area, even behind OFB's. Given things were close, I decided to head 15mins southwest of here and intercepted one of the storms near Wayne, IL late this afternoon. There was a lead storm, with a line behind it. The lead storm had a lowering and rotation for a time at the surface, but had a strong mid level meso/rotation. After a brief time of watching this unfold south of Wayne, a microburst signature formed a short distance from my location, northwest of Wayne. I raced north and intercepted it while I was in town. Winds were 60-70mph at my location, with tree debris flying around and penny size hail. Afterwards I went out on a short survey of damage and found there was a moderate sized swath of minor tree damage, with a smaller embedded area of significant tree damage...where numerous trees were uprooted or snapped at the trunk, large limbs were down, and two power poles were down. Winds were likely in excess of 70mph in this smaller axis. Below is a pic of the storm while I was sitting south of Wayne before the microburst, looking towards the meso to my southwest. This is the second year in a row I've managed to encounter a nearly direct hit from a microburst, the other being 7/21/17 not too far from here, though that one was even more significant.

Gino confirmed damage with that one.

There was likely just two tors in Cook county... .

91 ORD and 92 MDW today.
