Chicago Storm

The COC is holding together fairly well, and actually looks better than it did when it made landfall. There has also been widespread high winds/damage near the COC. Tupelo, MS gusted to 71MPH a bit earlier. .

Probably deserves its own thread, especially considering the rarity. .

Given how the upper air pattern is trending, any snow from both systems will likely be limited to IA/WI/MI.

GFS has trended towards the Euro with the first system, keeping and minor snow to IA/WI. Seems to be agreement among most guidance now with 2nd system as well, with snows for mainly IA/WI and pets of IL/MI potentially. .

Some guidance, such as the below HRRR, is really going all in... .

That’s actually very interesting. Even thought it’s later in the season and more significant troughs would hinder further north/west tracks...would have figured there would have been at least a few up into the region this late. .

I’m turning over a new leaf. Following in the footsteps of brother Alek. .

This new you is too optimistic. Not sure how I feel about it.

Jinxed.

54MPH peak wind gust at ORD over the past day or so, with much of the area having topped out in the 45-55MPH range during that time.

Hittin' it on a Tuesday morning, huh?

Sept was the 6th wettest Sept on record for Chicago... Top 10 Wettest Septembers: 1. 14.17" - 1961 2. 13.63" - 2008 3. 9.44" - 1977 4. 8.97" - 1936 5. 8.28" - 1894 6. 7.61" - 2019 7. 7.12" - 1986 8. 6.93" - 1886 9. 6.72" - 1927 10. 6.71" - 1970

Yea... ORD has been a bit of an odd-ball all summer temp wise, but it finally looks like the sensor is fully trashed now.

Delayed response, but I did end up chasing the tor warned storm on the 12th. I ended up intercepting the storm near Ashton, a bit after it had gone tor warned. Upon arriving, the storm was interacting with the warm front, and made a serious attempt at wrapping up and producing. Unfortunately, due to the warm front being in a NW/SE orientation, there was a small window of opportunity to produce..in which it did not succeed. I followed along east with the storm for a bit longer just in case it tried to do something interesting, before dropping off of it and ending the short chase. On the way home, another storm developed and went severe/tor warned south of the original storm. It was well north of the warm front, even so tried its best to do something...but ultimately failed as well. If the warm front would have been oriented more W-E instead of NW/SE, along with not retreating SW, activity likely would have been able to latch on to the boundary, and would have had a better chance at producing and would have had longevity.

2.28” of rain at ORD on Friday...easily broke the precip record for the date of 1.33” (1936). .

Looks like one more push of summer-like temps on Mon/Tue with mid to upper 80’s, before fall conditions quickly set in with highs in the 60’s/50’s beyond that as we push into October. .

I’m surprised how “low” those records are. .

89'd at ORD today. Hit 91 at MDW and 90 here. Other local sites in the vicinity also hit 90/91...so ORD lagged just a bit.

15th on the year now. 91 MDW and here. .

89-91 across the western/northwest suburbs right now. Immediate city area on south lagging a bit. Looks like the site is totally down, unfortunately. Needed it one last time for these two periods.

Bit late... But if things would have cleared out earlier in the day on the 3rd, we probably would have been looking at a fairly significant day. The tor near UGN from that small spud t’storm shows the potential that was there. .

Looks like we have two upcoming periods to tag the last 90(s) of the season. Tomorrow-Thursday and Sunday-Wednesday all have potential to be in the vicinity of 90. The biggest issues during both periods will be clouds, potential rain/t'storms and lower end UA temp thresholds. ORD has been sitting at 14 90+ days on the year for a while now, which is the average for the year. We'll see if we can tack on one or more, to push things above average.

Yes. .

Still waiting for TH to make a valid point.
