July 2011: Most extreme July on record for the U.S.
According to the National Climatic Data Center's Climate Extremes Index, July 2011 was the most extreme July on record (since 1910) with a value of 37%. The Climate Extremes Index is created by merging the various climate indicators (drought, flood, extreme heat, extreme cold, etc.) into an index that can be tracked over time. This month's record CEI was due to extreme warm minimum temperatures across the country, wet northern Plains and Great Lakes, extreme warm maximum temperatures, and the severe drought across the South and Gulf Coast.
It was the fourth warmest July on record for the nation, and the fourth warmest month overall with an average temperature of 77°F. Extreme heat continued to bake the South, and Oklahoma and Texas both had their warmest months on record. Oklahoma's statewide average temperature was a remarkable 88.9°F in July, which is the warmest monthly statewide average for any state in any month. Dallas, Texas hit or exceeded 100°F on 30 out of the 31 days in July. For the entire South climate region, which comprises Texas, Oklahoma, Kansas, Louisiana, Arkansas, and Mississippi, July 2011 was the warmest month on record for any of the climate regions.
As we noted in a previous blog, an unprecedented area of exceptional drought covered the United States in July, the largest area in the history of the U.S. Drought Monitor. 75% of Texas was in an exceptional drought, and the entire state of Oklahoma was in moderate to exceptional drought in July. The NCDC estimates that it would take 20 inches of rain to end the drought in one month in the worst hit areas of Oklahoma and Texas.
Figure 1. Texas and Oklahoma had its hottest and the state of Washington had its 11th coolest July on record last month, according to the NCDC.
Figure 2. Texas had its second driest July on record, and Oklahoma had its 9th driest according to the NCDC. California continues to be wetter than average, and last month was its 8th wettest July on record.

Your hosting company has jacked up their Plesk installation.
They need you in Texas. Go open your paint cans there.
Can't get it...gives a hosting error
cannot open
Sorry for your loss and I wish you safe travels.
also looks like home grown mischief (very weak though) as well in the GOM

Sorry to hear that W115....take care :)
Fails for me as well.
I could not open it StormJ
And this is usually what the pro-AGW people on here say. We both can play the whole cliche game.
Condolences to you and your family stay safe and take care of your business see you when you return.
Worked after I removed the www as you suggested.
Opens up to a page - Parallels Plesk Page.
Sorry for your loss. Be safe.

La Nina is like the knife in the back for Texas..something gotta give shortly and it just might be a TC..
nope, last time you were on I said that it was gone, guess you didnt see it :(
I read an article yesterday--and actually posted a link to it--that said it will take ten years for Texas' agriculture and livestock to recover from the current drought--and that's assuming 1) the drought ends PDQ, and 2) no other droughts occur over the next decade.
Lost my grandmother in December, very painful thing to go through. My deepest condolences to you and your family.
broke my keyboard + this one!
sure is..hope they ALL dont pan out..
Oh, that's already happening. The West Texas desert is spreading east. There are towns northwest of San Antonio that are on the brink of losing their water supplies completely. The lakes have gone dry. Severe water restrictions have been in force for ages, but are of little use when there's no rain to refill the lakes and reservoirs.
At least around here, this year's crops are simply gone -- I've seen so many fields of two-foot high corn plants burned to a dead brown husk -- and produce prices at the grocery store are higher than I've ever seen them. I have to wonder how far away Dust Bowl conditions are -- quite a ways off, I hope, but it makes me wonder how much worse things were during that level of historic drought.
There may be a mis-communication somewhere in there. There are some geologists who believe the Earth's core is cooling. From Wiki: "J. A. Jacobs was the first to suggest that the inner core is freezing and growing out of the liquid outer core due to the gradual cooling of Earth's interior (about 100 degrees Celsius per billion years)."
On another note, interesting weather in Florida. Palm Beach has shown a few vortex signatures off and on, but I didn't see much on Radial Velocity (.20, 1.00, 2.10) so it's probably nothing serious.
We tried that once this season already. Don didn't really survive to make landfall
still got over half of the season left..
That is really saddening to read. Hopefully this upcoming La Nina won't pan out during the winter and Texas can have the benefit of more passing storms.
Almost a foot this month so far
