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.

Isabel had an extremely pronounced blocking ridge to her north with a defined trough over Wisconsin, and the ensembles don't show that extreme of a setup. However, that doesn't mean that it can't result in storms sneaking toward the coastline.
500mb height anomalies on September 15th, 2003, when Isabel was about to start turning northwest in the SW Atlantic:
Not sure why you would call that assinine, old Emily is currenty moving SE and could ride around the High if it doesn't connect with the front ahead of it. He didn't say it was a definite, just that it's a possibility and in weather never say never.
Ok thanks! Always appreciate your input. Isabel was a dousy of a storm for me, knocked down several trees in my yard.
Might be something that I may need to watch in the next week or so.
Noooooooooooooo. Please. Just leave Emily. We'll see you in 2017.
I think 'Average' might better serve than 'Normal' since all they are doing is averaging the data...
Stormjunkie..... website still not showing up online.. who is your hosting service?
Do I ever,watched the eye pass wright over me..
If that is indeed Rita, boy do I ever remember it. Spent a long harrowing night under a mattress wondering when the roof was gonna go. Lived through it for months while the clean up progressed.
Also nice spin behind 92L

Hah! That would be great. She gets a second chance at glory. LOL
Read it again.
It means there is a possibility of these storms impacting the east coast.
Evening, hydrus. Don't think much will come of it. Very dry air down there. I suspect that blob off the African coast should be near the Islands by Saturday, though.
92L
Ah yes. She delivered my eviction notice while I was sleeping off the Texodus in Kilgore. Lol ;)
Third chance lol
When showing national Maps - referencing trends etc.
Can you please show all 50 States.
Us Hawaiian and Alaska Resident like to know how we are holding up too....
And this is why fretting over every little speck of CO2 that's emitted here in the US is a fool's errand, unless you want to bomb China back to the stone age to save the erf. Or boycott all the American companies that have moved overseas and take advantage of the more lax regulations and put a final dent in the global economy while you're at it (probably wouldn't be a bad thing, lots of human death and destruction but the earth would be saved, amirite).
And a surface trough has been added behind that low.
92L is not doing as bad as we thought. Maybe it will finally get mentioned at 8pm.
Yes, this is getting interesting.
Interesting indeed:

Until recently, the U.S. was the world's largest emitter of CO2 and by a substantial margin. Recently China has taken over this "honor". China has also taken immediate steps to reduce their carbon foot print. They, it seems, have a better grasp on the future than do we and are taking better and faster measures than we. The biggest reason that China now has more CO2 emissions than we do is largely in part due to our outsourcing our manufacturing to China. Do we wait for China to have lower CO2 emissions than we do before we take another look at lowering our CO2 emissions? Do we, once again, play a game of catch up with the rest of the world? We have not lowered our CO2 emissions. We outsourced them! ... Forget China. Why do we wait on China before we start doing our part?
This is nothing against G.W. Bush but, when he went on national TV and stated that if U.S. consumers didn't want to buy products from China, then they wouldn't. My immediate question was, where do you shop at?!?!?! Antique stores? I look at where products are made before I buy them and IF I can find that product that is "Made in the USA", I buy it. The problem is, there are very few products that I have this choice with. I boycott China every chance I get along with companies that outsourced our manufacturing to them. I still have respect for China. Our corporations? Not so much.
Was thinking the exact same thing.
Here's to a good summer and fall to all.
