First-Ever Death From a Dust Devil?

At least, I've never heard of one before. Details here.

T.S. Bertha is Born

Tropical storm Bertha formed near the Lesser Antilles overnight and its predicted path is above. It is not expected to affect the United States.

Rainfall Since 7am Saturday Morning

If you scroll down, you'll see a drought index map based on rainfall since 7am Saturday. These are the rainfall amounts for the last five days, since that map was published. The widespread rains in Oklahoma, New Mexico and Colorado have helped ease the drought a bit and more are forecast (see immediately below) over the next seven days.

Monsoon Rains Ease the Drought in the Southwest

Yes, More Flooding Possible in Colorado

Heard via Twitter (thanks for the feedback!) from Colorado readers that they are concerned the posting below might mislead people into thinking there is no chance of flooding in Colorado.

So, please allow me to clarify. Yes, Colorado has a flooding threat over the next 36 hours. I was trying to convey the more immediate threat has moved into Oklahoma and southwest Kansas.
The area in green is a flash flood watch. I would also add metro Tulsa to the potential flood area.

Shifting Heavy Rain Threat

Eads, Colorado, reported 6.21 inches of rain the last 24 hours. While light to moderate rain os forecast over many parts of Colorado the next 36 hours, the threat for the heaviest rains has shifted southeast into Oklahoma and southwest Kansas. Below is the forecast rainfall until 4pm CDT Thursday.

Some flooding is possible in low-lying and poor drainage areas. Remember, when driving, Turn Around, Don't Drown!

Large Area Threatened With Flash Flooding

Green = flash flood watch. Magenta = flash flood warning.

AccuWeather Regional shows high levels of Gulf of Mexico moisture flowing northwest toward south central Wyoming and the Denver-Boulder Metro area and, to a somewhat lesser extent, southern Colorado.
There is a second area from central Oklahoma to the eastern Panhandle that has a chance of heavy rain overnight.

End of July Drought Update

The map, above, shows how much rain -- in addition to the normal amounts of rainfall -- is what is needed to end the drought in each climatological region as of 7am Saturday.

Here is the rainfall since Saturday morning:

And, here is the forecast amount of rain for the next seven days.

So, by the first of next week, the drought will ease in a few areas.

Thanks Meteorologists!

From today's USA Today:

"We've seen this happen all over the state of Tennessee over the years," Ray said, "You hardly ever see destruction this bad without somebody being killed. We're thankful, thankful to God that we didn't get hit, injured or killed."

Hmmm. Wonder why there were no deaths?

Ray said his family took shelter in their basement as the powerful weather moved through the area. When he walked out, his roof was gone.

I suspect the reason Mr. Ray and his family were in the basement because they had been trained to do so by meteorologists over the years and because of the tornado warning that was in effect on that storm.

Yes, good luck plays a role. But, so do storm warnings and storm education. In addition to the information on this blog, there were many meteorologists doing outstanding work yesterday. Even with tornadoes from Massachusetts to Tennessee, not a single death. That isn't coincidence. That is the storm warning system doing what it is designed to do.

James Spann's Review of "Warnings"

James Spann is one of the nation's very best broadcast meteorologists and has saved innumerable lives with his outstanding coverage of severe storms. He is a man I admire and am proud to call him a friend.
He has read and reviewed Warnings: The True Story of How Science Tamed the Weather. Here are some excerpts:

For those that love weather, this is one of those books that is hard to put down. Not only is it a history of the severe weather warning system in the United States, it also weaves in the personal story of Mike’s long career...
Mike also look at the warning process for Hurricanes Andrew and Katrina in deep detail… what went right, and what went wrong. It is especially interesting to read the chapter “Murder by Bureaucracy” concerning Katrina.
I do believe you need to know where you have been to have a better understanding of where you are going. This history of severe weather warnings in this nation is a very important story for all of us, and Mike did a masterful job of telling it. I encourage all in the weather enterprise, and those interested in weather, to get a copy. It is a very good read.
You can read the review in its entirety here. You can read additional reviews or order a copy of Warnings here. If you enjoy reading this blog, you'll love Warnings
