I had a weather radio in my car rattling off current weather conditions for the area. This was around 3:30ish, and Rice Lake in Barron county had a 66° surface temp with a 64° dew point with winds out of the SE at 13 mph gusting to 18 mph.
Menomonie was clear skies with a temp in the upper 70's and a 60ish dewpoint.
So, surface temps close to dewpoint temps in Rice Lake with a steady SE wind is what sealed the deal on heading north.
The supercell to the northwest kinda stalled over northern St. Croix and southern Polk Counties and went severe warned before I got onto HWY. 53 north from Chippewa Falls.
I headed northbound all the way to HWY. 8 and then headed west toward the town of Barron.
The cell went tornado warned just as I was reaching the eastern end of town.
Looking on radar the cell had the classic 'hook echo' with an intense precip core just east of the town of Clayton. I needed to quickly slip through town and drop south on HWY. 25 to intercept the southwest flank of the storm.
I was slightly worried I would be caught in the forward flank of the storm somewhere on HWY. 25 between Hillsdale and Barron but managed to stay ahead of it just in time.
I couldn't see anything to the west from HWY 25 that resembled any supercell structure until I got a few miles down 8th avenue west just northwest of Hillsdale.
Then the storm showed it's ugly face.
A nice dark gray barrel shaped rotating updraft with a solid base straight west of my location. A constant low rumbling of thunder above me as the updraft slowly churned in a counter-clockwise motion.
Bolts of lightning horizontally piercing through the walls of this twisting beast as it began to grow more intense.
The forward flank precip core to the north had a yellowish gray tint. This storm was serious!
I kept watching the updraft base for any sign of a lowering or wall cloud. I couldn't make out any key structure at that level. I could see the the left edge of an intense rain curtain and that was it.
I decided to head back east onto HWY. 25 and stopped to watch it again.
By the time I got to HWY. 25 the mesocyclone was only a handful of miles to my west.
A nice beaver tail was rapidly feeding into the base from right to left. Then two more beaver tails would form. One of the beaver tails was so close to the ground it was scraping just above the tree line to my northwest.
But still, the area of rotation was completely wrapped in rain. A few times I could make out small funnel shaped sub-vortices that seemed to touch the ground and then dissipate. I wasn't sure what I was seeing at the time. Maybe my eyes were playing tricks on me?
The dark wide, rain wrapped wall was closing in on me fast so I quickly dropped south on HWY. 25.
When I got to Hillsdale I could see the outer rain bands whipping in fast from the west.
South of Hillsdale I ran into strong inflow winds for less than a minute.
Then RFD winds began to howl from the west, and I was probably going close to 80 mph at this time trying to get a safe distance between me and the mesocyclone.
I looked over my right shoulder out the rear window and seen a dark wall right over HWY 25 about a half mile behind me.
Cars and trucks heading north were driving straight into it. I was imagining the worse case scenario was about to unfold but miraculously no one was injured as far as I know.
The RFD winds were intense for a few minutes minute as they shook and swerved my car into a frenzy. Small branches and tree debris was raining down on top of me. I could hear the debris hitting the side and the top of my car.
I will admit, I was pretty scared.
I reached a few miles down the highway and decided to stop for a few minutes to gather my bearings. By this time the storm was wreaking havoc just northeast of Hillsdale and heading toward the outer-northern areas of Chetek.
A tornado was reported on the ground north of Chetek soon after. Looking on radar the area of rotation appeared to be wrapped in rain.
It was also getting to far ahead of me and I decided to halt the chase from there on out.
I did latch onto another supercell that was brewing to the southwest of the town of Ridgeland over northern Dunn County shortly after I abandoned the main supercell.
I got into position south of Ridgeland and seen a nice non-rotating wall cloud with that cell.
Some pea to dime size hail fell onto my location as well.
The wall cloud became deformed looking and soon disappeared out of sight.
I would follow that storm on HWY 64 east toward Bloomer.
The storm went tornado warned before it passed north of Bloomer and from where I was at pacing along with the storm along it's southern flank on HWY 64, I did not see anything tornadic with that cell.
The structure was very un-organized, elevated, and with heavy rain really close to the updraft base.
Im not even sure why it was tornado warned??
As I got to HWY. 53 near Bloomer I seen a small convoy of ambulances heading north. I had a bad feeling that they were heading into the tornado hit areas.
I got onto HWY. 53 and followed the emergency vehicles all the way to the first Chetek exit. They went one way to the north and I went another way toward the northeastern areas of town a few miles out.
I can see people ahead of me steadily filtering down a certain back road and I followed behind them.
I eventually ended up near the tornado damage path. A good size wood lot was tore up from west to east. You can tell easily tell where the tornado went through.
Several people with chain saws were heading up this little road.
I got out and followed everyone to an area where the road was blocked off by downed trees and powerlines for about a half mile.
Many people were there helping clear the cut up trees and branches, so I decided to get in there and help too.
Plenty of debris was scattered across the area. Powerlines were down everywhere.
It felt good to lend a helping hand.
I didn't know the magnitude of the storm until I got home later that night.
One person lost their life and almost 30 injured in a mobile home area north of Chetek.
Damage costs up to 10 million dollars.
The tornado would be rated as an EF3 and also declared as the longest tracked tornado in Wisconsin history since National Weather Service record keeping began in 1950. A whopping 83 miles on the ground!
I will never forget May 16th, 2017.
