A Record-Setting Blizzard Is Set to Blast the Midwest

Brrrr.

The Midwest is skipping fall and heading right to winter to end the week.

A potentially record-setting blizzard is bearing down on the region and could dump snow from Colorado to Minnesota. The Dakotas sit near the epicenter of the storm and could see up to three feet of October snow (yes, you read that right). Add in gusty winds and you have a recipe for life-threatening conditions. For a region that’s already dealt with one freak early season snowstorm, the latest blast of winter is hardly welcome.

Snow has already fallen across parts of the Rockies and Front Range as of Thursday late morning. Multiple accidents and pileups have been reported in the Denver metro area. Highways have been shut down as police struggle to respond amid worsening conditions. After topping out at 80 degrees Fahrenheit on Wednesday, Denver will struggle to reach freezing on Thursday. As of mid-afternoon local time, temperatures hovered at just 22 degrees Fahrenheit with a wind chill of 14 degrees Fahrenheit.

The chaos in Colorado is just a preview of what’s to come, though. As the storm pushes eastward, frigid air will continue to drop out of Canada and sweep across the Midwest. Along with rapidly dropping temperatures, the storm will usher in winds upwards of 60 mph and heavy snow.

Parts of North Dakota are under a blizzard warning. The worst is expected to hit mid-morning on Friday and last through Saturday. The National Weather Service said in its warning that residents should be ready for some serious weather: “Travel should be restricted to emergencies only. If you must travel, have a winter survival kit with you. If you get stranded, stay with your vehicle.”

The cold is likely to topple record low temperatures in a number of locations while the snow could set records for October, particularly for locations in North Dakota where the heaviest snow could fall.

The source of the wild weather is a huge contortion in the jet stream, a rush of air that races around the world from west to east. When it’s straight, it keeps warm air locked to the south and cold air to the north. But occasionally it can get wavy, allowing cold air to drop south into its troughs and warm air to pool north under its ridges.

This week’s contortionist act in the atmosphere is what will allow the chill to drop from Canada into the Midwest. To the west of the dip, warm air is filtering up in California and the Southeast. The warmth in the Southeast is notable, but in California, it’s raising risks of wildfires that have led the state’s biggest utility has intentionally cut power.

Research indicates that a wavier jet stream could in part be driven by rapid Arctic warming. The northern tier of the planet is heating up faster than the rest of the world. That, in turn, is causing the temperature gradient that normally keeps the jet stream taut to become a little looser, allowing for wobbles in the river of air. While nobody has done an analysis of whether this particular storm is tied to this phenomenon, researchers expect ripples in the jet stream could become more common. And with Arctic sea ice—a key indicator of warming in the region—just hitting its second-lowest extent on record this September, it sure fits a pattern.

We warned and said that things would happen. Even this was a part of the predicted pattern. Summer without spring, winter without fall. It will, of course, eventually be the end of us all. I’d like to think humanity can change its ways. But it seems that we are hellbent on bringing the end of days.

I think its time to realize that nothing we do will change those with the power. And its also time to realize they won’t stop until after the final hour. They don’t care who they kill - only so long as they have had their fill. Changing the world requires that we all stand together. But it seems that the monsters have won and will keep us apart forever. You can’t change others, you can only change yourself. So its time to put this away, and leave it on the shelf.

I wish you luck in all your futures and all your defiance. I’m going to walk away and listen to the silence. I need to make a few designs, access a few minds. See if I can put together all the parts. And hopefully manage a brand new start. Its been my plan to get off this rock for a while. But even if I don’t make it, at least I’ll go in style.
