Tornado kills four Boy Scouts in Iowa

Tragedy struck a Boy Scout camp in western Iowa last night, when a tornado swept through, killing four Boy Scouts and injuring at least 48 people. A tornado warning was issued by the National Weather Service 12 minutes before the tornado hit the camp at 6:35 pm CDT, but it appears the campers never heard the sirens, either because the sirens were too far away from the remote camp, or because the storm caused a power outage in the nearest town of Blencoe, which silenced that town's tornado siren.

Tornadoes also hit southern Minnesota, eastern Kansas, and eastern Nebraska yesterday, and the Storm Prediction Center recorded 52 tornado reports. A tornado caused major damage in Manhattan and Kansas State University, tossing cars and destroying several businesses. A half-mile wide tornado hit the town of Chapman, destroying 60 homes and killing one person. Another person died in a mobile home in the Jackson County town of Soldier. Yesterday's deaths bring this season's tornado death toll up to 118--the most since 1998, when 130 people were killed.



Figure 1. Radar reflectivity (top) and Doppler velocity (bottom) for the June 1, 2008 tornado that hit the Little Sioux Scout Ranch in western Iowa. The tornado was embedded in a line of severe thunderstorms that swept through the state, and did not exhibit the classic hook-shaped echo one commonly sees in tornadoes. The most dangerous tornadoes commonly show a hook echo and tend to be spawned by "discrete supercells"--isolated thunderstorms that are not embedded in a solid line of thunderstorms.

Tornado activity forecast
The Storm Prediction Center is calling for a "Slight" risk of severe weather across the Midwest today, from Michigan to Oklahoma. We can expect a few more tornadoes today in the affected region, although probably not as many twisters as were reported in yesterday's outbreak. The "Slight" risk of severe weather continues Friday across the Midwest, then shifts to the East Coast by Saturday.

Tropics
An area of disturbed weather has developed in the southern Gulf of Mexico between the Florida Keys and Mexico's Yucatan Peninsula this morning. The thunderstorm activity is under about 20 knots of wind shear, and is moving northward into the central Gulf of Mexico. I'm not expecting this to develop, but we should keep an eye on it. None of the computer models are forecasting development of a tropical depression in the Atlantic in the coming seven days.

Anything that forms in the Gulf will head to the Northwest with high pressure ridge axis of the eastern seaboard extending outward into the Gulf.

Kman, glad to hear you guys got some rain; lack of the wet stuff seems to be a common complaint lately, unless you're in the upper midwest or New England...

A lurker with a question.....The local weather people are stressing the blob will be nothing but a blob. We here in Houston MAY see some rain from it. With that thought I saw the winds in the area of the blob is to drop from 10 to 15 kt to 10kt or less. How would this effect it or will it at all?

The NHC has the floater that is focused on the GOM disturbance labled "Invest", I guess they are planning on tagging it soon.

Nothing up on the Navy site for the GOM at this time. I guess they will wait and see how it evolves over the rest of the day before deciding to tag, or not tag, the area officially

Drak, what are your thoughts on the GOM? Sorry if you've answered this, I haven't read back much.


Its a mid to upper level low. It needs to work it's way down to the surface and then we would look for subtropical development since you would have a cold-core low vertically stacked with the surface low. This is the type of development you see early in the season and late in the season where you have a persistent upper level low that sits there. Just something to monitor right now. Surface pressures are not falling and there is no indication of 850mb vorticity maximum.

Hi Flood

Everything ok so far in the NW Caribbean. lots of rain in the past 2 weeks which we really needed after months of drought.

That floater invest may not necessarily be a formal invest. Sometimes we have seen a floater headed up that way over an area of interest before it is officially designated an invest. Kind of odd but thats how it's been in the past

Hi Keeper,

What's up ?. The shear in the Caribbean is keeping the early season in check but the GOM looks as if it is trying to get something going since yesterday.

Could the swirl in the GOM be what the UNYSIS GFSx MON 16JUNE is hinting at or this another feature?

Also, Emanuel has another hurricane-climate paper in BAMS. In this one he details some of the contributions to climate thats TC bring about.

Also admits that "it must be stressed that a good theoretical understanding of the environmental control of storm frequency is lacking." Then briefly covers what is known so far.

Lastly, he covers some of the arguments and responses from experts in the field concerning our historical hurricane record.

Rather lengthy, but here it is.

Quiet on the Blog today with the diminished tropical activity I see. Global Warming

Ok, I'll bite.

Take a look at the BAMS article covering details from the International Summit on Hurricanes and Climate Change. Link.

Interesting details about hurricanes, historical proxies, evidence of increased activity in some locations during the little ice age, and caveats associated with interpretation of those proxies (such as track changes falsely showing an increase or decrease in activity).

You guys know that proxy data shows more activity 3800 to 1000 years ago on the N Gulf coast than we have had in the last 1000 (including our "records")?

(Oops, fixed link, sorry.)
