U.S. experiences warmest 12-month period on record
The past twelve months were the warmest twelve months in U.S. history, said NOAA's National Climatic Data Center (NCDC) on Tuesday, in their monthly "State of the Climate" report. Temperatures in the contiguous U.S. during May 2011 - April 2012 broke the previous record for warmest 12-month period, set November 1999 - October 2000, by 0.1°F. The past twelve months have featured America's 2nd warmest summer, 4th warmest winter, and warmest March on record. Twenty-two states were record warm for the 12-month period, and an additional nineteen states were top ten warm. NOAA said that the January - April 2012 period was also the warmest January - April period since record keeping began in 1895. The average temperature of 45.4°F during January - April 2012 was 5.4°F above the 20th century average for the period, and smashed the previous record set in 2006 by an unusually large margin--1.6°F.

April 2012: 3rd warmest on record
April 2012 was the third warmest April in the contiguous U.S. since record keeping began in 1895. Ten states had a top-ten warmest April, and no states were cooler than average. But what's really remarkable about April was that eight states--Illinois, Indiana, Kentucky, Michigan, Wisconsin, Ohio, Pennsylvania, and West Virginia--had average April temperatures cooler than their March temperatures, even though their April temperatures were still above the long-term average for the month. These statistics show just how remarkably warm March 2012 was. Most extreme was Illinois, where April 2012 temperatures ranked in the top 20% for warmest Aprils, yet were cooler than March 2012 temperatures.

Most extreme January - April on record
NOAA's U.S. Climate Extremes Index (CEI), an index that tracks the highest 10 percent and lowest 10 percent of extremes in temperature, precipitation, and drought, was 42% during the January-April period, over twice the average value, and the greatest on record. Remarkably, 82% of the contiguous U.S. had maximum temperatures that were in the warmest 10% historically, and 68% had warm minimum temperatures in the top 10%, with records going back to 1910. The previous records were 56% (2000) and 57% (1992) for maximum and minimum temperatures, respectively. The percentage area of the U.S. experiencing top-10% drought conditions during January - April was 19%, which was the 17th greatest since 1910. Extremes in precipitation as computed by the CEI were near average for the January - April period.

Levi is still around ...not posting as much right now ..once we get more into the "season" I'm pretty sure he will be here regularly
Yes you are correct. I am in Midtown/Museum District area. I know Ritaevac is in this area too, but I believe he is further south (I may be mistaking). We certainly need to keep in touch during storms and etc. I believe Jeffs713 is in this area as well.

Pretty special place, the Carolinas.
No wonder Press is so Passionate about it/them/whatever.
Wait until Hurricane season ;)
Wow, decent for the Carolinas.
What about "mi soon come" a little Jamaican creole
A few weeks ago, Klaus Wolter from Colorado State gave a talk in TX about drought. He stated they will know in 2 months whether El Nino will form.
They only Jamaican creole I know is "haul your ...,clot' man.
101 Birthmark: What money? Whose money?
Missed the most important question: Where is MY cut?
(Not to be impolite, but the rest of ya can get in line behind me)
claart is the phonetic spelling I believe.
They are both picturesque places. Have you ever been to it/them/those?
yes....South Carolina....and Northern South Carolina....
What are they doing ???
Now you're correcting my creole?? I don't know what it means, but everytime I question my bill in a restaurant there, that is the response I get.
Nope!
But if ever I get back to the US, that area is high on my list..
LOL ...Mother's day is my quit day!
Good luck!
Are you talking to me? Are you talking to me?
Your Brain and Lungs say, tyvm.
I also suggest fruit for something to do with yer hands, as I cant think of anything else you could do with them...as well.
Harummph...
What about Florida?
I haven't been sober in nine days either...it seems to help......Good luck back at ya...
Sorry....
Consider it a "pronunciation clarification" rather that a correction.
I would never "correct" you. It would be pointless...
:):))
I was near you once and dat kinda splains a few things I believe.
Did you try the Shrimp Creole in Tromso, I made dat.
The Laplanders enjoyed it.
That's right! Paradise....
I haven't had a cigar in 9 month. I prefer Cuban's but the Flor De Filipinas are nice too.
Our Cyclone season may have 1 last system before it's done...
a tropical low is located about 400 kilometres northeast of Timor and this is expected to move slowly southwest over the next 24 to 48 hours. This does carry the slight chance of developing into a category 1 tropical cyclone, and this may have some impact over western parts of the Top End and the Kimberley area around Thursday and Friday. Showers have been forecast for Darwin today and tomorrow.
Tropical cyclones in May are unusual but not unprecedented, with an example being tropical cyclone “Herbie” that struck the WA coast near Carnarvon on 21st May 1988.
I guess that they are telling you to leave the restaurant
Been there.
Unfortunately, there was too much shopping every time.
I don't do Malls very well.
Would love to see the Florida 'outback' though.
Eclairs, and chocolate bars help. So does a dozen glazed doughnuts followed by chocolate pudding pie with heavy cream.
Don't worry either, you will not gain any weight at all!
Come see our 'outback', it's only "small" but very spacious, lol.
There is a Dangerous word in there somewhere.......
I never had Shrimp Creole in Tromso. The Sami eat everything.
sounds perfect...unfortunately my wife is on some sort of health jihad....if I even say the word 'doughnut'...she'll call the paramedics....
LOL to that.
I like spacious. Even if it's small...
Does this look familiar?
Sneak into her phonebook.
Replace the Paramedics # with the Pizza delivery place....
That should do it!
I've always wanted to see the Simpson Desert. Is the sand really red as it looks?
Excellent idea!!!!
'specially after Saturday nights.
By Tuesday morning it's usually back to grey.
LOL!
Fabulous !
you will feel small when your out there and there is no one around for 100's of kilometres. Make sure you check out the red centre also. you'll need a warm coat as temps can get to as low as -10c(14f) over night.
That part of Norway must be one of the most beautiful places to be to see those lights.
