PUBLIC INFORMATION STATEMENT NATIONAL WEATHER SERVICE NORMAN OK 1206 PM CDT TUE JUN 4 2013 ...UPDATE ON MAY 31 EL RENO TORNADO... METEOROLOGISTS WITH THE NATIONAL WEATHER SERVICE AND RESEARCHERS FROM THE UNIVERSITY OF OKLAHOMA CONTINUE TO INVESTIGATE INFORMATION RELATED TO THE MAY 31 EL RENO TORNADO. WITH THIS INVESTIGATION... THE TORNADO HAS BEEN UPGRADED TO AN EF5 TORNADO BASED ON VELOCITY DATA FROM THE RESEARCH MOBILE RADAR DATA FROM THE UNIVERSITY OF OKLAHOMA RAXPOL RADAR. IN ADDITION... THE WIDTH OF TORNADO WAS MEASURED BY THE MOBILE RADAR DATA TO BE 2.6 MILES AFTER THE TORNADO PASSED EAST OF US HIGHWAY 81 SOUTH OF EL RENO. THIS WIDTH IS THE WIDTH OF THE TORNADO ITSELF AND DOES NOT INCLUDE THE DAMAGING STRAIGHT-LINE WINDS NEAR THE TORNADO AS DETERMINED BY THE HIGH-RESOLUTION MOBILE RADAR DATA. THE 2.6 MILE TORNADO PATH WIDTH IS BELIEVED TO BE THE WIDEST TORNADO ON RECORD IN THE UNITED STATES. .EL RENO TORNADO RATING: EF5 PATH LENGTH /STATUTE/: 16.2 MILES PATH WIDTH /MAXIMUM/: 2.6 MILES FATALITIES: N/A INJURIES: N/A START DATE: MAY 31 2013 START TIME: 6:03 PM CDT START LOCATION: 8.3 WSW OF EL RENO /CANADIAN COUNTY /OK NEAR COURTNEY ROAD ABOUT 1 MILE NORTH OF REUTER ROAD START LAT/LON: 35.495 / -98.095 END DATE: MAY 31 2013 END TIME: 6:43 PM CDT END LOCATION: 6.2 ESE OF EL RENO /CANADIAN COUNTY /OK NEAR INTERSTATE 40 AND BANNER ROAD END LAT/LON: 35.502 / -97.848

More than two dozen family members, church friends and neighbors came to the Horn's home to help recover items that can be saved." (AP Photo/The Oklahoman, Jim Beckel)

The Oklahoma City area has seen two of the extremely rare EF5 tornadoes in only 11 days. The tornado that hit El Reno had a record-breaking width of 2.6 miles. The one in Moore, a city about 25 miles away from El Reno, killed 24 people and caused widespread damage." (AP Photo/Kim Johnson Flodin, File)
Wednesday Severe Threat. NOAA SPC shows a 10% chance of (significant) severe storms in the hatched area over the Texas Panhandle, an enhanced risk of tornadoes and large hail. A slight severe risk extrends from Amarillo to Oklahoma City, Tulsa and Little Rock.

About 25 such storms have struck the city in the past century. The city's location near the tip of Florida makes it highly vulnerable."
As NASA explains: Coronal holes are the source of strong solar wind gusts that carry solar particles out to our magnetosphere and beyond. They appear darker in extreme ultraviolet light images (here, a combination of three wavelengths of UV light) because there is just less matter at the temperatures we are observing in..."
Negative NAO: Amazingly Persistent Pattern. A strongly negative North Atlantic Oscillation correlates with big north/south swings in the jet stream, frequent intrusions of Canadian air capable of spinning up flooding rains and tornadoes. Last year at this time the NAO was strongly positive, meaning powerful west to east winds, keeping cold air bottled up over Canada, resulting in record warmth. A strongly negative NAO also increases the potential for Atlantic hurricanes hitting the USA (with a Bermuda high closer to Florida - steering storms toward the Caribbean and Gulf).
Tracking The Tropics. Note the surge of moisture coming out of the Gulf of Mexico, producing soaking rains from Tampa to Atlanta (by Thursday), Washington D.C. and New York (Friday). Flash flooding is likely with some 3-4"+ rains up and down the east coast. A cold upper air low sparks showers and a few rumbles of thunder over the Upper Midwest and Great Lakes today and Thursday. The west stays dry - I'm increasingly concerned about drought spreading west of the Rockies, setting the stage for a potentially record year for wildfires.
Outlook: Even Greener. Models show more showers today (4 km NAM prints out nearly .8"), then a light shower Thursday giving way to dry skies Friday into part of Saturday; another risk of showers and thundershowers by Saturday night. Graphic: Iowa State.
Welcome To Late April. We're still lagging the calendar by 4-6 weeks; a pattern that kicked in back in February, and shows no sign of quitting anytime soon. Your best odds of 2 dry days, back to back? Next Monday and Tuesday.

Stephan Lewandowsky: The Mind Of The Conspiracy Theorist. Yes, Uncle Bud, I'm talking about you. Here's an interesting audio interview with Chris Mooney at Point of Inquiry: "From 9-11, to the death of Osama bin Laden, to the Boston Bombings, there's been a consistently bizarre and troubling reaction by some members of the public. We're referring to the people—a minority, to be sure, but a surprisingly large one—who always seem to think there's some kind of cover up. The U.S. government, they feel, was really behind the attacks on, uh, itself. And as for Bin Laden—well, he isn't really dead. These people are called conspiracy theorists, and, their particular form of irrationality is uniquely befuddling. It has been often denounced, but rarely understood. That's too bad, because conspiratorial thinking clearly plays an important role in science denial, on matters ranging from the connection between HIV and AIDS, to the safety of vaccines, to global warming..."
