Ole Blizzard Bill getting a little worked up about “bonus snows”, a “once in a few every decades event” and “thunder and lightning”…among other things for NW Ohio in this update: https://fb.watch/hzvxTpV8mU/?mibextid=v7YzmG

 

Edit: Mentions he’s not sure how these computer models are gonna handle the potential snowfall and wind together with this.

Wow!  Some lollipops along I-70 in Ohio!

I'm on C just because history is the best way to predict the future. Either way im ready. Both machines fired right up (Gen and snow thrower) and nothing can get blown away. Let er rip and come what may.

If Ol’ Bill is getting worked up about it, then it’s worth paying attention to.

The past decade... Definitely 

Found this.  At least some discussion out there about it. Would be a pain trying to figure if it is one.  Someone will need to come up with an App.

By Brandon Miller, CNN Meteorologist

Bomb cyclone is a term given to a rapidly strengthening storm that fulfills one important criterion. Generally, pressure must drop 24 millibars (a unit of pressure) within 24 hours.

However, that benchmark is also based on the latitude of the storm. So, the millibar requirement can change depending on where the storm forms.

But why’s it called that?

The term can be traced back to a meteorological research paper published in a 1980 edition of Monthly Weather Review.

Its authors, MIT meteorologists Fred Sanders and John Gyakum, built upon work by Swedish meteorology researcher Tor Bergeron, who had initially defined “rapidly deepening” storms as those that met the 24 millibars-in-24 hours criterion.

But Bergeron was way up in Scandinavia, where storms strengthen much quicker because of the latitude (remember the Coriolis effect?).

Sanders and Gyakum adjusted the ground rules to vary based on latitude. They added the term “bomb” because of the explosive power that these storms derive from rapid pressure drops (though Gyakum reportedly doesn’t use that word anymore because of its reference to weaponry).

How do you adjust the rules?

Since you read down this far, I feel obligated to give you the actual equation — and if you love it, perhaps you should consider pursuing a career in meteorology!

To calculate the pressure drop needed for a bomb cyclone, you take the sine of the latitude where the low pressure is located and divide it by the sine of 60 degrees (and you thought you would never use trigonometry).

Why 60 degrees? That’s the latitude where Bergeron was when he developed the initial scale.

Once you do the calculation, multiply that result by 24, and that is the number of millibars the storm’s pressure must drop to officially qualify it as a bomb cyclone at the given latitude.

He also mentioned to his wife how hungry he was for more food. Maybe he has the munchies. 🤷🏻‍♂️

Lol. I have no idea who this guy is but will now look for this video just to see this. 

Blizzard Bill is a Northwest Ohio weather treasure:

Bill is awesome. Always took the time to respond to my emails when he was working for 24 and 13 in Toledo. He knows his stuff. He actually broke out pencil and paper during one broadcast about 15 years ago during a system where models were showing scant snow amounts for NWOH and called a higher amount and nailed it. 

Glad he still does videos because his experience is missed on broadcast TV.

FWIW, in regards to excessive Kuchera ratios (not considering the effect of wind fracturing), here's hr45 of the RDPS.  Ratios west of the front are well in excess of the 25:1 that the WPC believes is the max ratio.  (If I understood the discussions of the last couple of days correctly)
