March 2012: warmest in U.S. history
Not only was March 2012 the warmest March in the U.S. since record keeping began in 1895, it was also the second most extreme month for warmth in U.S. history, said NOAA yesterday, in their monthly "State of the Climate" report. The average temperature of 51.1°F was 8.6 degrees above the 20th century average for March, and 0.5°F warmer than the previous warmest March in 1910. Of the more than 1,400 months that have passed since the U.S. weather records began in 1895, only one month--January 2006--had a larger departure from its average temperature than March 2012. A remarkable 25 states east of the Rockies had their warmest March on record, and an additional 15 states had a top-ten warmest March. Only four states were cooler than average, with Alaska being the coldest (tenth coldest March on record.)

March 2012: most daily records broken of any month since July 1936
A wunderground analysis of weather records from NOAA's National Climatic Data Center temperature record database reveals that more daily high temperature records were broken in March in 2012 than for any month except July 1936, going back at least 100 years. Fully 11.3% of all daily high temperature records for the month of March in the U.S. are now held by the year 2012, for the 550 stations in NOAA's National Climatic Data Center database that have weather records extending back at least 100 years. The only month in U.S. history holding a higher percentage of daily temperatures records is July 1936. That month holds 14.4% of all the U.S. high temperature records for the month of July. That month occurred in the great Dust Bowl summer of 1936, the hottest summer in U.S. history.

Summer in March 2012: records not merely smashed, but obliterated
Among the 15,000 daily records for warmth set in March 2012 were 21 truly astonishing ones: cases where the low temperature for the day beat the previous high temperature for the day. It is quite rare for a weather station with a 50+ year period of record to break a daily temperature record by more than 10°F. During "Summer in March, 2012", beating daily records by 10° - 20°F was commonplace, and NOAA lists 44 cases where a daily record was broken by more than 22°F. Extraordinarily, four stations broke a record for the date by 30°F or more. Canada holds the most surreal record of this nature during the "Summer in March, 2012" heat wave: Western Head, Nova Scotia hit 29.2°C (85°F) on March 22, breaking their previous record for the date (10.6°C in 1969) by 18.6°C (33.5°F.) Canada also had several stations break their all-time warmest April temperature records in March.

Last 3 months and 12 months were the warmest on record
The previous 12-month period (April 2011 -March 2012), which includes the second hottest summer (June-August) and fourth warmest winter (December-February), was the warmest such period for the contiguous United States. The year-to-date period (January - March) was also the warmest on record. NOAA's U.S. Climate Extremes Index, an index that tracks the highest 10 percent and lowest 10 percent of extremes in temperature, precipitation, and drought, was 39 percent, nearly twice the long-term average and the highest value on record for the January - March period. The predominant factor was the large area experiencing extremes in warm daily maximum and minimum temperatures.
Analyzing the "Summer in March, 2012" heat wave
Dr. Martin Hoerling of NOAA's Earth System Research Laboratory in Boulder has posted a thorough analysis of the heat wave, which he calls, "Meteorological March Madness 2012". He explains that the event was probably a natural phenomenon, one that was predicted more than a month in advance by NOAA's long-range CFS model. A similar, though not as intense heat wave occurred in March 1910. However, he notes that the approximate 0.5 - 1°C warming in the Ohio Valley/Midwest U.S. in recent decades--due to human-caused emission of heat trapping gases like carbon dioxide--has significantly increased the odds of major heat waves occurring. He speculates that the odds of a 1-in-40 year heat wave in the Midwest may have increased by about 50% due to human-caused global warming, but that we really don't know how much global warming may have increased the odds of the March 2012 heat wave, saying "This issue of estimating reliable statistics of extreme, rare events continues to be a matter of active research." He estimates that human-caused global warming likely increased the intensity of the March 12 - 23, 2012 heat wave by about 5 - 10%, and concludes by saying, "The probability of heatwaves is growing as [human-caused] warming continues to progress. But there is always the randomness."

One tornado warning in NE tx and a severe thunderstorm warning on the panhandle, it's just started to ramp up.
3 of the most powerful cells are moving less than 15kts!
It's April. Stuff should be moving pretty fast, and instead its like coasting or stalled out.
I had just planted my corn seeds and also my Pepper Plants, when dat hit. So Im Hoping the corn germinates, but the pepper plants did ok so far.
It was a mini bow echo.
The oceans seem to be draining into a hole over in the Indian Ocean. Not much else besides a handful of tornadoes and some frost, wildfires and earthquakes. Dead dolphins and diseased polar bears.
In Texas, often it seems they wait for spotters to report things.
U forgot bappit's wu book club circle of festive assorted New Climate Change Novels, fiction included.
: )
how is that NOT a tornado?
Its true, the EQ dislodged the drain plug.
It's working fine for me

Smart little me knew to wait until the artificial heat wave passed on. I was waiting for this cold snap to come first. After this comes through, we should be frost-free in the Southeast.
Oh, and btw, weatherh98, you've got mail if you're around, just a question i need answered :)
really, is water really runnind down into a crack and turning to stone?
how much?
Apparently you missed it, too. Read back through the blog. I think RitaEvac thought that one up.
Yeah two magnitude 8+ earthquakes
Thanks for the update

HAVE NOT OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES
CAN ASSUME THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL
STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS.
AS LOCAL CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE
ACTION THE ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL
AUTHORITIES.
THIS WILL BE THE FINAL BULLETIN ISSUED BY THE PACIFIC TSUNAMI
WARNING CENTER FOR THIS EVENT UNLESS ADDITIONAL INFORMATION
BECOMES AVAILABLE.
THE JAPAN METEOROLOGICAL AGENCY MAY ISSUE ADDITIONAL INFORMATION

Technically it does, but you won't learn that till geology 101.
Water subducts in trenches and certain other locations.
Under high heat and pressure, water lowers the melt temperature of rocks substantially, and also reacts chemically with many compounds in rock, producing new magmas and new types of minerals, which are then erupted to the surface many ages later as lava.
HAPPY BIRTHDAY KORI
Nice... here in Georgia, I wait til the end of April... I saw people starting gardens here in the middle of March!!!
