Chicago Storm

Tomorrow is very uncertain and murky at this point. Many more questions than answers.

First 80°+ high temp of the year at ORD on Sunday, with a high of 81°.

i can't do that long of a flight. otherwise i'd head to australia, where they will have four between 2028-2038. i'll have to wait for the back-to-back one's in 2044 and 2045.

they are dead to me because they don't offer bbq sauce. horrible establishment.

Ended up with great viewing conditions for the eclipse yesterday, as the thicker portion of the high level cirrus cloud deck moved out just in time for totality. As expected, the experience blew out my 15 seconds of totality while riding the edge of the 2017 eclipse just SE of STL. This go-around, having full totality for a solid 4 minutes, was great. I didn't believe it going into it, but it's all true... When totality hits and it goes dark, similar to after sunset on a normal night, things change... Birds got quiet, and nightlife came alive. Instead of having just the western horizon filled with yellow/orange like a normal evening sunset, it was 360° in all directions. In the sky above, it wasn't black and dark like night, but more of a deep/dark navy blue-like shade. Also visible were Jupiter and Venus, as well as eye visible prominence/coronal loop. Looking forward to the next two total eclipse opportunities in 2044 (Montana/Canada) and 2045 (Western/Southern US).

Stationed near Franklin, IN. As expected, have had high clouds this morning and afternoon here, varying between scattered to overcast at ~30,000KFT. Looks like the thicker stuff should be out of the way in time for totality.

Have decided to focus on the IN portion of the corridor I had mentioned. Heading down to Indy later today, and will monitor trends tonight/Monday morning to adjust as needed. For that MO/IL/IN/OH corridor, it seems like the better chance to avoid the worst of the cloud situation is there…possibly.

I'm honing in on somewhere in the corridor from SE IL, near the IL/IN border, into C IN. Guidance seems to be in best agreement in keeping this corridor out of the expected high clouds, or at least keeping them minimal until after the eclipse. TX/OK/AR/MO all seem to be a lock to have high clouds of higher coverage and significance. While it may still be visible through the higher clouds in some areas in this corridor, the experience will be far from the same. I never really considered the Northeast as a possibility, as it's going to be cooler (Would rather view in quality weather conditions), and there will likely be a higher density of viewers/travelers there due to the proximity to the higher population centers along the East Coast... And plus, I'm just not really interested in heading up that way anyway. In 2017, I was down in Southwestern Illinois, just outside of the STL metro. I was right just inside the range of totality, so I got to experience brief totality and the effects of riding the edge. This go around, I plan on setting up in full/max totality.

Had a period of snow in the area Wednesday morning, which then transitioned to RASN by midday and then RA for the afternoon. There was another period of RASN this morning, which transitioned to RA by midday. No measurable snowfall accumulation at ORD with either bout of precip the past two days.

One of the best looking and most textbook examples of occlusion we have probably seen in this area/region for as long as I can remember...

There is sort of an exotic phase with this one. Even a bit of fujiwara effect in the Great Lakes for a time between the northern and southern stream main vort lobes and then again out east later on.

Solid garden variety t’storm activity ongoing across the area tonight.

Event snowfall total of 1.0" here at ORD.

Depends on where the F-Gen band sets up. Wherever it does, there will likely will be a corridor of up to 6", maybe even higher.

Anyone notice the Euro change that was made? It still comes out earlier even with the DST change.

Any severe threat up around here for Thursday vanished as quickly as it appeared.

It most definitely is the demise/final warming of the SPV, no question on that at all.

Some of these tornado warnings today have been eek bad.
