Post your Bomb Cyclone mega snow storm Bronco pics 🌨️ 🌬️

[lapazleo]

Survived the blizzard of 78. 42 plus inches of snow sustained winds of 60mph gust to 90 mph + and the lowest barometric pressure ever recorded look it up. Other than some cold this ain't nothing.

-40 windchill. 30-40 mph winds. Close to 4 feet of snow on the ground (this and previous storm a few days ago.). Closer to the big lake (Superior) it’s worse. 64 mph gust about an hour ago. Not great but it is winter. Good for the moose, bad for the deer. Stay warm

I'm going to nerd out for a bit so feel free to ignore me... and @mtclimb3r can correct me if any of this is wrong. (I studied meteorology in college but got bored and switched to engineering.)

I don't know who came up with the name "bomb cyclone," but the actual technical term for these sorts of weather events are bombogensis... which is really just a really bad cyclogenesis. Cyclogenesis is a system that results in a dramatic drops of barometric pressure.

These types of storms have always happened, but what is strange about them now is how far south they are occurring. Traditionally the jet stream would keep these types of storms above the 35-38° latitude line... roughly the Arkansas/Missouri state line, middle of Tennessee, North Carolina, etc. If you were south of that line, these super cold bombogensis systems were relatively rare (once every few decades or so) because the jet stream would effectively form a barrier and keep the system up north.

For the past decade or so, we've seen the jet stream effectively collapse, and areas of the country (Texas, MIssissippi, Florida, Louisiana, etc.) that only saw this type of weather once every few decades are now seeing it almost every year. Which people online love to talk about, and I suspect people down south hate. This type of weather in Chicago is common and boring. But Tallahasse, Florida having a HIGH of 32° tomorrow when their average LOW is 44° is the type of stuff the internet and news media loves to eat up.

Welcome to the nerd zone! You are correct! In my textbooks is was called explosive cyclogenesis. This is the type of storm that sank the Edmund Fitzgerald.

The less complicated explanation is that the polar jet has been weakening as a result of arctic warming. Poles are warming faster than the equator and the equator-to-pole temperature gradient is what creates the polar and subtropical jets.

-5 here in Southern Indiana today we got about 3" of snow last evening.

Where in Indiana ? Evansville here

you can nerd out on wind, temp, etc and at different elevations (as shown by pressure in hpc - hectopascals)

-25 with the wind this morning. I am told the extreme shifts in temps here in KY is one component to making great bourbon. I guess it’s time to have a glass and see. Stay safe!!!

Anytime winter weather hits the midwest and east coast, everyone looses their mind. That same storm system flows through the Mountain time zone, crickets lol.

No body but those that live in the mountain time zone has even heard of it.

-9 here in Central Illinois this morning. Not much snow, but wind has been insane.

Not much snow in Sangamon County but boy is it cold.

Meanwhile in Miami, today's high 80F:

I feel personally attacked, but...

Haha. Awesome.

*Post now includes a video - even captured the American flag at the beginning.

Here’s a couple pictures from an hour ago just outside of Grand Rapids, Michigan. Ripping through a few drifts. Special thanks to my wife for standing out in the strong wind and cold.

and that's after it's already gone through the PNW

Pretty much average here. Gonna wire up my trailer harness in a few. Stay warm, everyone!

March of '78. My mother had to drive in it to the hospital to give birth to my brother. The Ice is what she remembers the most. Trees snapping over left and right from the weight. No power for days. Central Illinois.
