10th Anniversary of Greensburg Tornado

May 4 is the 10th anniversary of the Greensburg, Kansas, tornado. That storm destroyed the town -- literally.

This week is ten year celebration of the town's comeback. If you are in the region, I highly recommend paying them a visit. I've been there several times and they are great people with great hospitality.

Addition: Roy Wenzl's story of the town's recovery is must reading.

Storm Total Rainfalls

Let's begin with the 24-hour rainfall totals ending at 7am. More than eight inches fell in a number of areas.

Here are the regional storm total rainfalls through 7am this morning. Please note the different color scale.

Here is a storm total close-up of the area now experiencing severe flooding.
Note the areas of more than ten inches. In southwest Kansas, more than four inches had fallen (with snow still falling) which represents a quarter of its average annual precipitation.

Current Weather Across Central United States

This is as of 10am CDT. Interstate 70 is closed between Hays and Denver. Winds are now gusting to nearly 70 mph in the western Oklahoma Panhandle.

17" inches of snow on the ground in Colby, Kansas, along I-70.

From Cindy Preszler in St. Louis:
Highway 141 and I-44 is in the south St. Louis County suburb of Valley Park. I-44 will likely be closed Monday as the Meramec River reaches the second highest level in recorded history. 

Today's Tornado Risk

We've already had several tornadoes today.

Here is the overall tornado risk. Keep in mind that 5%, brown, is the significant threshold.

And, below is a tornado watch in effect until 3pm.
Please keep up on the weather in these areas.

Sunday Fun: Bill Nye Loses It

You must read Anthony Watts' and Josh's commentary (with a bonus cartoon!) pertaining to Bill Nye's latest idiocy.

Videos of the Canton, Texas Tornado

Addition: Path Map

--Original Posting Below--

There are reports of three dozen injured in the tornado.

Here it is at its formation. If you listen carefully, you can hear the "waterfall" sound associated with tornadoes.

And, here it is a few minutes later. You can see the tornado throwing trees and, again, the waterfall sound.

-- Additional Video --
Here, the tornado has matured into what storm chasers call a "wedge" which means there is a low cloud base and it is at least as wide at the bottom as it is at the top. For a moment, the sound is more of a roar. You will also be able to see the result of the tornado hitting electrical transmission lines.

The video below is from my AccuWeather colleague, Reed Timer.

7:45pm Flood Update

The purple symbols are where major or record flooding is forecast from now through the next five days.
If you live anywhere near one of the purple symbols, please check local sources for specific flooding information.
These are the smoothed rainfall amounts over the last three days ending at 6pm.

This will be the last flooding update.

Tornado Watch in Texas

The watch is in effect until 10pm. A tornado has struck in or near the town of Canton, Texas, with considerable damage. No word on injuries as yet.

4:20pm Flood and Blizzard Update

Here are storm total rainfall amounts as of 2pm CDT.
As much as 9 inches have fallen over far southwest Missouri. Severe flooding is being reported around Branson as well as other locations. The magenta are current flash flooding warnings.
The greens are various flood forecasts and warnings. The orange = blizzard warnings! Power failures are high likely. The pink is a winter storm warning.

Unfortunately, more rain is on the way. Here are the forecasts for for the next three days. In the High Plains it is a forecast of the moisture content of the snow. 

The Environmentalists Finish With Washington for Another Year

Big Climate is finished trashing Washington, DC for another year. So glad they let us know that the rest of us need to treasure the environment.

2pm Flood Update. Heavy Rains Continue

Radar at 1:55pm. Click to enlarge.

Earlier forecast still looks good.





The Anti-Global Warming March...

...in Denver today.

This is known as the "Al Gore Effect."

Catastrophic Flash Flood Danger

Turn Around, Don't Drown
Using AccuWeather's exclusive model and NWS models that were initialized at 10am along with radar and other tools, I cannot overemphasize the flash flood danger through midnight and, likely, beyond. The forecast rainfall amounts are 10am to 10pm.

Please do not travel in these areas. If you do travel, do not try to cross flooded areas by foot or by car!


Extreme Flash Flood Danger

If you live in these areas, especially the red or purple, please be ready to take flood precautions. Whatever you do, do not drive into a flooded area: Turn around, don't drown!

60th Anniversary of the Ruskin Heights Tornado

From the May 435 magazine:
With its profound effects on many who witnessed it, the tornado
spawned a generation of people interested in the weather or
pursuing careers a meteorologists such as Mike Smith, who
chronicled the tornado in his 2010 book, 
Warnings: The True Story of How Science Tamed the Weather.

May 20 is the 60th (how time passes!!) of the Ruskin Heights Tornado. This tornado killed 44 people, 7 in Kansas and 37 in the Missouri suburbs of Kansas City. It was one of the most important tornadoes in the history weather science in the United States:
  • It was the first time the Weather Bureau issued what would now be called a tornado warning. By today's standards, 44 is a high death toll. In 1957, it was very low considering it was night and the density of the population.
  • Three students of Grandview High School became meteorologists as a direct result of the tornado. All three would go on to make major contributions to today's tornado warnings and the lives they save.
Warnings, while a completely true story, is written in the form of a novel. So, if you are looking for a great book about weather, a gift for Mother's Day or for a graduation gift, please consider Warnings: The True Story of How Science Tamed the Weather
