July 6-8 Severe Weather

Recommended Posts

I see the couplet on his posted radar image, clear as day. How many scans it was there, Tony would have to tell you as I don't have access to the radar product he used, but I'm guessing it was there more than a couple scans. In MY mind, THAT is a "radar-detected' tornado. 

 

Now, not sure if anyone has seen this or not, I just found it on facebook as I sat down to eat after working outside most of the day:

 

http://www.wzzm13.com/story/news/local/metro/2014/07/07/why-no-warning-issued-with-kentwood-tornado/12315353/

 

Basically, it says:

 

GRAND RAPIDS (WZZM) -- Meteorologists from the National Weather Service addressed the media late Monday afternoon following Sunday night's EF-1 tornado touchdown in Kent County.

Many residents are wondering why there was no warning or even a watch issued with this storm.

The twister, rated a high-end EF1, had winds of 100-110 miles per hour when it struck at 10:20 p.m. near 64th Street and Burlingame Ave. SW. It was on the ground for 10 minutes and 6.25 miles and was 900-1,200 feet at its widest, according to the NWS. It lifted around 10:30 p.m. near the area of Breton Road and 28th Street SE.

RELATEDEF-1 tornado touchdown confirmed in Kent County

National Weather Service meteorologists say they couldn't detect the twister because it was hidden and rain-wrapped. Meteorologist Daniel Cobb says the tornado also developed behind the radar screen.

He added the twister was also unusual because it was a spin-up tornado, meaning instead of descending towards the ground, like the large funnels you see in the Great Plains, this one started on the ground.

"The time the radar detects the velocity of this one, it's on the ground. It developed right at the base of the ground, and then grew upward, the opposite way it's supposed to happen," he said.

Cobb says the worst damage was from the U.S. 131 and M-6 interchange to 44th Street and Kalamazoo, then it started to weaken. The worst damage was trees snapped in different directions, trees blown into garage doors,and carports ripped off.

Cobb says if this tornado arrived during the day, spotters would have had a better chance of seeing it form.

The last EF-1 to hit Grand Rapids was in 2001. The last tornado was a EF-0 in 2006, at a Caledonia golf course, Cobb said.

***End of post, emphasis on text is mine.  Here's where I'm confused. There was an obvious couplet on radar, we saw this, so how does "National Weather Service meteorologists say they couldn't detect the twister because it was hidden and rain-wrapped" occur?

Also, what does "Meteorologist Daniel Cobb says the tornado also developed behind the radar screen" mean exactly? (Sorry, this editor won't let me unbold stuff for some reason)

Horrible...

Some pretty cool mammatus clouds over Cincinnati this evening as most of the region was effected by some marginally severe thunderstorms.  

 

 

I knew I should have gone to the Reds game tonight ..... I figured it would get rained out but downtown's the one area that has escaped the rain!  

 

 

(also, did I really want to go see the Cubs?)

There hasn't been a post since May 22nd in the Upstate/New York sub-forum. (Aside from my own) They really should just delete that sub-forum completely. Even in winter it is 4-5 posters. I'm so lonely. :(

GRR has the Kentwood tornado touchdown time as 10:20 pm.  I'd have to go back and check but I thought there was a couplet on it before then.  Also, that line about the tornado forming upward is interesting.  They haven't released more detailed survey info yet so I wonder if there were eyewitnesses to that.  It was dark so it's not as easy to see.

Tornadotony's post (#69) was at 21 minutes past, board time, and figure it took a minute to get it posted. If it touched down in Byron Center, just west of US 131 (with 6 injuries), then the couplet should have been blatantly obvious by the time it crossed over US 131 on it's way to Wyoming and Kentwood. There should have been a warning. 

 

As for the "tornado forming upward" statement, I'm really not buying that. The rotation happens in the atmosphere, the ground isn't creating a tornado IMO. Sounds like someone grasping at straws to me.

My post was well after the tornado was over.

 

And as for the "tornado forming upward," that's called a non-descending tornado.  There have been papers authored that show that they are actually rather common.  What's more is that some recent research from OU brings into question whether or not there's actually any such thing as a descending tornado.  Some of the most recent high-res observations suggest that, even if a TVS descends within a storm, there may be a point where a concentrated vortex forms near the surface and rises and that most, if not all, tornadoes are technically non-descending.  This is why you'll never see me say that a tornado "touched down" anymore because it's unlikely that "touching down" ever actually happens.

Interesting stuff, thanks for sharing.  I didn't know that they were so common.  I believe the 1999 Salt Lake City tornado is one example of a non-descending tornado.

Thank you for clarifying those points, tt. It's just hard for me to get my head around the idea that the rotation originates at the surface instead of aloft. It's always been drilled into me that the rotation forms aloft and works it's way to the ground.
