Wrapping Up the Midwest Bomb

What a storm it was for sure. It looks like the lowest pressure was around 28.20″, or 954.96mb, recorded at Orr and Bigfork, MN. This blows away the previous mainland US record set in Cleveland, OH in 1978 of 28.28″ or about 958 mb. In terms of the damage, yesterday alone had 287 wind reports and 24 tornado reports. The previous day had about 150 wind reports (a lot though from another system in the Carolinas) and one tornado report. So, all in all, it looks like we probably ended up with close to 400 wind reports and 25 tornadoes from this storm in the Midwest, which is remarkable. Lots of links on this one:

SPC Mesoanalysis for 10/26/10 at 5 PM Central Time, near the peak of the storm.

A full recap on the pressure record is here.

A few tornadoes were confirmed in Ohio.

About eight tornadoes were confirmed in Central Indiana.

A couple of stronger tornadoes were confirmed around Chicago. Some good imagery and information here.

Here’s some video from WSBT in Indiana of a tornado destroying a pole barn.

The highest confirmed wind gust I can find is about 77 mph in Greenfield, IN. In addition to all the wind and storminess, there’s also the snow aspect of this storm! As with most fall storms, this one dragged down some cold air, enough to change any liquid to snow in the Dakotas and Minnesota. Thus far, Harvey, ND is the champ with 8″ of snow. Duluth, MN isn’t far behind though with 7.4″. Blizzard, High Wind, and Winter Storm Warnings continue today for much of the Upper Midwest.

The strong winds also helped to change the lake level of Lake Michigan, with westerly and northwesterly winds shifting water from the Illinois/Wisconsin side to the Michigan side. This is actually not terribly uncommon, but still pretty cool. I recall several instances of this happening on Lake Erie when I worked in Upstate NY.

More info on the storm in Minnesota here.

And some really cool loops and imagery on the pressure falls from the NWS in LaCrosse, WI here.

But is it really the record?

As is always the case with almost any record, there will be claims, disputes, etc. that, “Well, it’s not REALLY the record.” And of course, this time around, we have that as well. Folks in the Northwest are amused by the shock and hype of this storm in the Midwest…because storms such as this routinely impact them every winter. They’ve got a good point, as some of the pressures measured in past winter storms there (specifically one in 1995 measured at 958 mb, not even near the center of the storm) have indeed been routinely close to some of the “record” readings.

A slightly sarcastic tone in this entry from Dr. Cliff Mass, who publishes a great Northwest weather blog.

A great, great history of wind storms in the Northwest is here.

That all being said however, the truth is that in terms of actual measurements on land in the lower 48, away from the East coast, this storm is currently king.  But I’m sure one day, with better monitoring now in place in the Northwest, we’ll shatter this record as well.

But let’s not forget, this storm actually started in the Northwest too!

  1. I wrote a bit about this storm as well. I also read Mr. Mass’ blog, and I thought he was a bit too sarcastic. In fact, I think he was serious, and he sounded like a west coast elitist while he simultaneously trashed east coasters for being elitist. I think he could have toned it down a bit.
