Chicago Storm

91 ORD today (25). 89’d here and at MDW. .

90 at ORD (24) and here (22) today. .

But we want it nowwwww. .

This map is actually a good illustration of how the derecho quickly changed character rapidly as it pushed into the LOT CWA. It went from vortex dominant across DSM/DVN CWA’s, to MV dominant fairly quickly into the LOT CWA. My best guess on why this happened is...For one, the derecho had entered a post-mature stage...Second, the main vortex that moved from north of DSM-Marshalltown-CID eventually weakened as it encountered a disturbed environment from the RFD supercell. At this time it became more MV dominated. .

Hawkeye and surrounding folks of Cedar Rapids better have some damn good pictures/video to share when they get power back in another week or two. The more I hear about how things went there and see pictures/video from there, the more I want. .

This might be the dumbest post in this threat in a while. .

.

MV’s were not as predominant until the character of the derecho changed as it existed the DVN CWA, so I’m not sure there would have been many. .

.

Every time I post, they add another. .

ComEd did a broad brush estimation time of Saturday for everyone. Gotta think it’ll likely be longer for the harder hit areas. .

How far is this from you, @A-L-E-K?

91 ORD (23), 90 MDW (19) and 90 here (21) today.

Gusting up around 60mph now with the backside winds. .

Definitely caused by higher than the 62mph at ORD.

Yea, winds have increased once again here as well. Gusting 50mph+ here now, which is stronger than the main line.

62MPH peak gust at ORD.

Pretty zzzzz up around here. Peak wind gusts up to ~50mph for a short time, with the leading edge of the line. Looks like severe winds are more localized to where the smaller MV's are located in the line now, compared to the entire line earlier.

Bookend vortex just north of Savanna now, moving ENE. This will likely bring the heart of the jet through the entire Chicago metro. .

Real or fake Hawkeye? .

Given the current 86mph gust at DVN well behind the main line, it’s safe to say the jet is not aloft...it’s at the surface. .
