The National Weather Service has upgraded the high wind watch to a high wind warning which runs from 7 a.m. Tuesday-7 p.m. Wednesday. It appears we could establish a new record for the lowest October barometric pressure in this storm. Models put Chicago's barometric pressure at 29.05" Tuesday morning. If true, this would break the old October record low of 29.11" set Oct. 19, 1937, Oct. 19, 1947 and Oct. 24, 1959.
The storm's minimum central pressure of 960 millibars (28.35") Tuesday in northern Minnesota is below the 980-millibar reading in the Edmund Fitzgerald storm on Lake Superior in Nov. 1975. It's the equivalent of a Category 3 hurricane.
The curl visible off the West Coast on this CIMSS UW-Madison satellite time lapse in riding an extraordinary 220 mph speed maximum in the jet stream will become the storm expected to explode as it rides across the Dakotas and Minnesota Tuesday.
Wind gusts could reach mid-60s
Frank Wachowski of the National Weather Service reports Chicago's strongest October wind was 70 mph recorded Oct 28, 1892. Model wind profiles put sustained winds 2,000 feet above local terrain here at 63 mph by Tuesday afternoon. Subsidence in the region of the storm under which Chicago will be positioned after the passage of a squall line early in the day (6-9 a.m.) threatens to bring these winds down to the surface as damaging non-thunderstorm wind gusts.
Check out this animation of the spin-up of Tuesday's mega-low in the nation's mid-section. This is a time-lapse of the National Weather Service's high resolution GFS model. It puts the storm's minimum pressure at 957.5 millibars which translates to 28.28".
Our Obama inspired wind turbines will get a nice workout.
It’s been a typical rainy day with some gusts here, nothing to brag about. The temp dropped but for all the hyperventilating, it’s been no big deal here in Western WI.
We’re experiencing some very strong gusts as I type, probably 50 miles and hour or so. Just watched a long stream of migrating blackbirds or grackles go by outside my window. It was like a scene from, “The Birds.” They were being tossed by the wind, swirling and circling, just barely missing rooftops and windows. It was an amazing sight.

High winds/ heavy rains here. The pressure was at 28.42 mb a few hours ago... lowest since ‘98!
oops... 28.42”, That’s here in Northern MN.
I saw on the news the all time record low barometric pressure reading’s were broken today in MN. We haven’t really experienced anything other then rainy blustery windy conditions (W. WI) my daughter said they have a lot of power lines down and driving she said was bad because it’s so windy where she is (outside of Milwaukee).
Heh-heh... That ain't how it works... You'll just be raking someone else's leaves ;)
Truck blowover a little north of me today.

Wind has died down again for now but the real wind is due tomorrow.
Don't mean to make light of it... Hope you are all hunkered down and battened up...
I was planning to when I retired. Which WAS to be in five short years. But since I’m getting divorced, ALL retirement plans are temporarily on hold.
But The Good News is that The World Is My Oyster now and I won’t be stuck Down On The Farm forever. :)

Ouch, Diana! Sorry to hear about the divorce. That’s some rough stuff. Hugs to you. You always have the absolute best, most positive quotes. I have faith you’ll do just fine.
Yeah, we’re the envy of the world because of our weather. ;’) The freshwater inland seas called the Great Lakes have waves like the seas, but they come at ya faster because of the lack of salts. So, the same storms will knock a boat apart faster on the Big Lakes.
She’s blowing pretty good, but nothing we’re not familiar with.
It’s surely getting much colder.
My early teen son just assured me his choice of shorts for school tomorrow will be just fine. The kid’s about to get some real life schooling tomorrow.
Live and learn. :)
Lake Michigan looks like it has a slight wind tide, looking about a foot higher than normal on the shores.
The waves will be big (or I should say bigger) by tomorrow, so this could be interesting.
Interesting! How does that work? What is the science behind it?
It did get worse here last night we lost a tree and it’s snowing now but as you said nothing we haven’t seen before.
She howled pretty good last night. light rain, trying to snow.
Yawn.
As a kid, I used to LOVE to go out to Big Red during storms and watch the Lake Michigan waves crash. I was out there (at Big Red, Holland, MI) the day the Edmund Fitzgerald was broken in half. Incredible storms, spray was over the top of the lighthouse.
