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".
That would be interesting to know what the pressure was when the ship went down...
Plus..r u the same Sam Adams that defended Ex-Gov Blogobitch???
Don’t be dissin’ Dave.....He the last male full-time meteorologist in the Twin Cities that likes girls......and he doesn’t do global warming, either.....
Any weather experts out there who can tell me the prevailing winds in NE Illinois tomorrow? I suppose I could look at the isobars, but 1. I’m lazy, and 2. I might not remember how to read them correctly.
No, that must be a different Sam Adams. This Sam Adams would throw him into Boston harbor - without a life jacket!
Wind’s been whipping up in TX, too, nothing to account for it.
It’s quiet here, too, just a light rain happening. The next couple days sounds like they’re going to be interesting, to say the least.
Time to clean a few things off the deck...
Just finished up outside. I took down my flags, my wind chimes, all of my grapevine wreaths and fall decor (I had a party here this past weekend so the house was pretty ‘fancied up’), emptied the birdfeeders, made sure the rainbarrels were FULL so they’d be nice and heavy, opened the greenhouse so the wind blows THROUGH it...
Y’all say a prayer for me! I have a HUGE honkin’ antenna (from the 70’s; I can’t take it down by myself!) on the roof of the side porch and I wouldn’t be surprised to see that torn off and stickin’ in the side of the barn come morning!
It’s a little ‘breezy’ out right now, but nothing to be alarmed about. Yet.
Added a brick each to the pockets of my barn coat for the morning walk with the dogs, LOL! (Just kidding!)
I have ‘dangerous’ trees tagged to be cut down, but that’s not happening for another week...maybe that won’t have to happen at all? (Hope not!)
I may as well move to Kansas! :)
Gonna get kinda rough on ole Gitchiegoomie
Ok, now you're in my old stomping grounds. I grew up in Durand, but the Air Force sent me to Florida (sigh). Sorry, you may be in God's country up there but I haven't shoveled snow in quite a while. ;p
OH I would never diss Dave I’ve watched him for years he the real reason I put on that station trust him and like him.
Hope all the shipping is in safe harbor.
The big lake, it’s said
never gives up her dead
When the gales of November come early!
All of the long piers going out into the lakes have memorials to people who have been washed off of them. Most seem to be teenage or young adult males.
They will shut themselves down if the winds are too high to prevent damage. They'll either freewheel or the blades will turn 90-degrees into the wind to minimize rotation. Depends on the design.
We were scheduled to have our house re-sided tomorrow. The contractor called today to postpone until Thursday. Probably a good idea. :)
I hope the new roof holds. We were hit hard with golf ball size hail in the July 17th storm.
Very moving tribute at the link...
God’s revenge for giving the Nation Obama.
Living here in San Diego with the fires, earthquakes and mudslides..we do miss the weather events of the Midwest where we grew up. What we need to establish is a free port somewhere in the Midwest where old conservatives could go to live with flat tax,minimal property tax, sales tax and death tax.
Seriously?
