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.

Quoting TxHurricanedude11:
Oh Wow!A bad inbox mail I just got from jason...anyone get one too?
I did too txhurricanedude, yesterday, did it contain some foul language?
You should forward them to admin.
+10 .. Exactly, it's too early to tell and plus.. Remember Hurricane Earl last year.. Models had Earl going near Bermuda to the east... Then the shifts occured.
He didn't really write anything, he wrote that nasty comment in the title, and when I look at NEW MAIL, how would I know that's Jason or not.
Thanks!
Forecasting such patterns out to 4 weeks is very difficult. However, we have seen so far this season that west Atlantic troughs haven't liked to hang around too long before leaving, and as a result, we have already had one landfall on the U.S. and another storm that got within 100 miles of the coast. If the SE Canada ridging is finally showing up as the ensembles are currently forecasting, then the pattern may finally be going with the analogs that foretold this. If it is, then the dangerous pattern that we warned about before the season began may be ready to entrench itself, but we will just have to see. We're going to deal with the pattern on a storm-by-storm basis, as always. The average pattern over a few weeks does not necessarily mean that a random hurricane will encounter that same pattern on a daily time scale.
Not only are the troughs week they are pretty far North hanging out in Canada and then exiting off to the NE pretty quick allowing the High to build back in. 92L might start to go North but then could easily get pushed back West into the East coast, way to early right now to call it a fish storm IMO.

TPW loops show a large moisture envelope that is running into a large pocket of dry air.
Yes, but what about when the user adds a new handle every few days? Jason and all of his aliases already occupy a solid 15 slots on my ignore list. I'm just to the point of reporting each one, minusing it, then clicking on ignore user.
Its all the same person who is blatantly trying to evade ignore lists.
Looks a heck alot like Earls first runs, don't it? :P
Sorry but not calling this a fish until I see a recurve. The pattern shows blocking, and weak troughs..
Off to work, won't be back till tonight, have a nice day P451 and everyone..
Then if I were you I'd start using the ignore feature to filter on the ones who are starting the trouble. I'm with you, I just want to read the opinions of people who have a good understanding of the tropics and share my opinions with them and learn. The other crap needs to go.
you're a smart guy!
I believe it. He's almost as bad as a few of our other notorious people on here, as far as being irritating goes.
Also anyone who is arguing against AGW please don't use the omg it's such a cold winter. The dynamics of a possible AGW change atmospheric conditions much more than just temperature it leads to more severe weather and that includes worse winter weather include it being colder.
For many reasons I believe in climate change in general more than global warming. The climate has continually changed in the world for billions of years and we only have 150 years of exact data and only 60 years of accurate worldwide data since satellites have given us accurate worldwide readings.
My take is to practice the precautionary principle. Ok although I don't believe in global warming per se I do believe we should be moving to greener renewable energy that doesn't pollute our environment.
Have a good day and can we please get back to talking about the tropics
I'm currently contacting admin about the situation with Jason.
Yes. In fact, no storm that formed within 50 miles of 92L's current coordinates ever made it into the Gulf of Mexico. Of course 92L is not a storm yet, but the point is still fairly clear.
this is a case of Jason getting hacked. The real Jason always posts his pics. Also to the rest of you out there ... this is a blog not a club...you don't get to chose your members. blog and let blog.
It incorporates the Beta Effect and the initial vertically-averaged steering. It does not dynamically forecast the steering pattern, but uses the current one.
sorry to bother you again but a quick question. I am thinking about studying meteorology.
What are the basic requirements to study this field and what are the main courses I would have to take?
Meteorology has always fascinated me ever since I was a kid. Weather in general is quite interesting especially hurricanes
thanks Levi!
Correct and guess who's paying em in Goldified Oil!!!
Yes the humidity has left the eastern US..we are in the 90's here today but low humidity..I will take that anyday compared to what we have been experiencing..
I assume you are asking about prerequisites. A meteorology major will take you through at least a little bit of just about everything dealing with meteorology. Standard prerequisites include math up through differential equations, and at least two semesters of physics. The programs usually require the usual core humanities and arts requirements as well.
