Chase 070917 Blue Earth - Nicollet Co. MN

The GPS Track is not true due to equipment outages mid-chase. It is however, accurate enough to provide background and position detail. This is one time when carrying back up equipment saved the day. I think location and positional data is critical both during and after a chase.

Since the NWS does a much better job at "Day After" wrap ups, I'm going to begin to eliminate information pertaining to the actual storm event and focus on items exclusive to our chase alone. The reason being is I'm realizing these entries are a LOT of work to put together and end up being duplicated by the NWS anyway. So, a summary of this event can be viewed at the MPX NWS Web Page

I initially drove to Sauk Centre MN thinking the initiation would occur just north of there mid to lat afternoon. After noting the boundary had begun to set up south of there, chase partner Brad Winger and I decided to meet in Wilmar MN. As I drove, the CU field began to become robust indicating we were where we needed to be. Now all we needed was an updraft.

This was a fun cell to watch just explode before our eyes. It's been a while since I had an unobstructed view of the birth of what would become the supercell thunderstorm we'd chase for most of its life cycle.

This well rooted (and well sheared) anvil was just to our west and feeding the new initiation in the video below.

This is why you don't chase at night. The ragged cloud overhead was in fact, a rotating wall cloud.

And the lightning was so quick, We never even saw it. Point #2: Never expect lightning to light your way.

That touched down shortly after it crossed the road ahead of me. This became the Courtland MN F0 TOR which occurred north of town. Fortunately, it produced a small amount of damage to the siding of a nearby barn.

Not a good idea to get out of your vehicle during one of these...

Here's a replay of the chase. Focus was hosed for most because this was recorded using an old iPhone with the "Broadcast Me App. Works great except for one very important thing:

You can't disable auto-focus.

Chase 061117 Monticello MN (Morning) SE MN (Afternoon)

We're going to call this one "The 2Fer". Early Morning MCS plows through the metro like a boss dumping a shit-ton of hail in the NW suburb of Coon Rapids. You can read the Day 1 here. Along with the Preliminary Storm Reports.

I sure hope this isn't going to hurt...

My view of the approaching line.

As you can see, This line was not messing around.

My Sunday morning drive. Don't you people sleep?

Chase 051717 Northern Iowa, Owatonna MN, New Prague MN

We get two route maps on this one. GPS tracking unexpectedly quit on the first leg so, the backup was put to work. This is why we have backups.

Exactly one day after the Chetek WI tornado, a major portion of  Iowa, and slivers of SE MN and SW WI were under an enhanced outline in the 1630Z (i.e. 1130 CDT) day one outlook from the Storm Prediction Center.

10% TOR? Yeah, let's go.

Target: Mason City IA. As I head down to meet the front, this greets me.

I decided to keep out of Mason City proper choosing to hang out just North of the city. By this time, the sky was really beginning to boil.

A short time later, things just exploded and the chase was on... North.

And then the second tornado watch of the afternoon popped up. How fortunate, right where I was going...

More to come as I sort through the photos and videos...

Chase 051617 Chetek WI. (EF-3)

First chase of the season found me dashing out of work at 1635 right into rush hour traffic at 1645. Heading east on I94 at that time of the day is not for the faint-hearted or impatient. And I dove head long right into it. No matter, the storm I was interested in was dead ahead and churning wildly.

Radar at the time was showing things moving in an east north-east direction and if I was going to have any chance of getting near it,  I was going to have to move North... Quickly.

I ended taking Hwy 95 to Stillwater where I prayed to the nautical gods that the bridge spanning the St.Croix was down and letting vehicles pass through to the Wisconsin side.


With that little bit of drama set aside. I bolted up WI 35 just as fast as I safely could falsely empowered by the new radar detector perched upon my windshield. 90% of the time, I drive in a realistic fashion (i.e. following with the pace of present traffic. I mean, think herd mentality, they can only chase a couple of us down right?)

I will say the detector is a nice addition just to tell me what I'm coming up on even when speed isn't a factor. If it's not barking at me, In this situation, i'm getting a little heavy on the pedal to make up lost ground. Maybe 10% more speed. Detectors mean nothing if you're in a ditch.

East on WI 64 gave me a wonderful view of what I would eventually be under (provided I caught up to it of course.)

Finally within reach, I made the fatal move of not continuing east on Hwy 64 choosing to follow Hwy 53 North toward Chetek which by then, had already had the storm pass through it. The better choice would've been to continue east and then intercept north on Co Rd. 73.

In all, it was good to get the rust out. Plenty of items that need to be reassessed before the next time out. Time to go have a beer.

The National Weather Service survey of the event can be found here.  As it turns out this tornado is now the longest track in Wisconsin at 83 miles!
