IMADreamer Posted April 10, 2011 Share Posted April 10, 2011 On our way back to our hotel in Davenport - what an absolutely amazing day. We literally saw so many tornadoes we lost count. Several multi-vortex tornadoes. All kinds of footage and pictures. Will try to go through some of it tomorrow morning. Very sobering to to see the damage and injury reports. Also we rarely saw/heard towns/cities activating their tornado sirens - kind of discouraging really. I wouldn't at all be surprised to see they didn't have sirens. Many towns don't.

I can't verify for the rest of Iowa but I know in the Webster/Humboldt County area sirens go offs but they don't carry well at all. My grandma doesn't live far at all from town,roughly a 1/2 and it the sirens can be heard if your outside but unless your paying close attention you don't notice it inside the house. Also have to give her a call if severe weather is moving into the area. Carry on though, probably me just being overly sensitive to Iowa being put down.

Remember that these systems are supposed to be outdoor warning systems - the mets here have been hammering on that point recently - probably because they are trying to sell some weather radios.

jcwxguy Posted April 10, 2011 Share Posted April 10, 2011 Got home from chasing a few hours ago. Went pretty well considering my time was limited and was thinking bust for a while for my area. I headed up to Norfolk, Ne and then decided to head west to catch a storm i saw going up (wanted to stay on the back edge to avoid the hail core before it got going good). I caught up to it around schuyler, ne and caught some nickel size hail. Took a few pictures of the storm-sorry there arent that many. http://s259.photobuc...mview=slideshow Link to comment Share on other sites More sharing options...

turtlehurricane Posted April 10, 2011 Share Posted April 10, 2011 Tiny Cell just north of St. Joseph, MO... will that blow up too? It's certainly possible, the atmosphere is unstable, we've just been lacking forcing. Looks like there might be a boundary east of the IA/NE border, down into MO, that is firing up now. Basically this is a small cold front looking at obs, associated with a weak wave that the formative MCS is riding on. Link to comment Share on other sites More sharing options...
ArtRosen Posted April 10, 2011 Share Posted April 10, 2011 http://www.siouxcityjournal.com/news/local/article_6f622336-630d-11e0-96fe-001cc4c03286.html "Mapleton looks like downtown Beirut" MAPLETON, Iowa - With 10 minutes' warning, residents of Mapleton escaped serious injury when a devastating tornado ripped through the town about 8 p.m., cutting all power and wiping out blocks of the Monona County town of 1,294. "Mapleton looks like downtown Beirut," Monona County Sheriff's Deputy Roger Krohn said. At Burgess Health Center in Onawa, Iowa, hospital spokeswoman Beth Frangedakis said three people were admitted with minor injuries suffered in the tornado. She didn't know whether they had arrived by ambulance. Early reports indicated there were no fatalities or serious injuries. The American Red Cross set up shelters at the Mapleton Community Center and Maple Valley/Anthon-Oto High School, and an emergency response vehicle was sent to provide food for residents and emergency personnel. Iowa Gov. Terry Branstad approved an emergency proclamation for the county Saturday evening. Krohn said 50 to 60 percent of the town had been damaged or destroyed. He said he had spotted the tornado, which he estimated was three-quarters to a mile wide and hit the city from the southwest, heading northeast through town.

csnavywx Posted April 10, 2011 Share Posted April 10, 2011 So Chi Storm, myself and 2 others rode the Mapleton supercell from its infancy (first radar echoes) in eastern Nebraska all the way to Pocahantas, IA this evening. What an amazing storm. It occluded and re-strengthened over a half dozen times, and at a couple points had several mesos all rotating around each other. Just before it hit Mapleton, it had occluded and formed this massive cyclonic gyre (essentially one big meso) with an extremely long and impressive inflow tail. We rode to Mapleton to get ahead of it, and stopped under the BP gas station awning there to take shelter from one of the many hail shafts this thing spit out along the way, which were extremely prominent and very noticeable. It was truly awesome to see it dump a massive load of hail and see it fall to the ground in a matter of seconds. About the time we got to the station, we had another hail shaft threatening the vehicle, so we hunkered down. Right at about this time, it cycled, and produced a new meso within a couple of minutes. Chi Storm caught a snapshot of the meso at the time the tornado was developing. We hopped in the vehicle immediately and sped away from the station, as it had literally developed and moved towards us from just a few hundred yards away. Luckily we got to an escape route right down the street about 20-30 seconds before it did. It then proceeded to chase us out of town and eventually grow into a big tornado. The shot Chi Storm took above was looking back down the road, and though you can't tell from the picture, it was heading right for us at a pretty good clip. We got beat up a bit by the FFD, but luckily was able to ride the edge and not take serious damage to the vehicle. After hunkering down near Battle Creek, we caught up to it in time to see it dropping another tornado. Later, we got some great lightning and structure video. The storm structure tonight was simply awesome. Link to comment Share on other sites More sharing options...

SluggerWx Posted April 10, 2011 Share Posted April 10, 2011 Will this cell in Ida Grove turn tornadic before it reaches Pocahantas within an hour? It just keeps getting bigger... Link to comment Share on other sites More sharing options...
turtlehurricane Posted April 10, 2011 Share Posted April 10, 2011 Setting the alarm for 4:30 am since it looks like we're in for some hail. The front in IA is flaring up good, should become a big squall line with all the instability and the LLJ roaring. Should see isolated tornadoes too, could be strong ones.

Iastfan112 Posted April 10, 2011 Share Posted April 10, 2011 Quick shot of pea sized hail to wrap up the night for me. Definitely was not expecting it, but then my weather radio went off and woke me up for a T storm warning awhile back. Link to comment Share on other sites More sharing options...
TheWeatherPimp Posted April 10, 2011 Share Posted April 10, 2011 Here is one of my very very blurry video captures - the video is much better (I'm working on uploading it) but this is a wedge tornado that was on the ground just Southwest of Pocahontas, Iowa Link to comment Share on other sites More sharing options...
