A large upper-level storm system is approaching central Oklahoma and moving east, into eastern Oklahoma and western Arkansas, bringing the threat of heavy rain, gusty winds, and tornadoes.
Severe thunderstorm warnings were posted early on March 19 in Oklahoma, Kansas and Texas. Oklahoma also has a flash flood warning centered on Oklahoma City. Texas had a tornado warning near Midland earlier in the day.
The National Weather Service issued warnings today, March 19, 2012 for eastern Oklahoma and western Arkansas which stated
"Dangerous/potentially life-threatening flooding is expected." Forecasters at the National Weather Service expect 4 to 8 inch rainfall totals through Wednesday, March 21, and possibly moderate and major river flooding.

Edward Olsen of NASA's Jet Propulsion Laboratory in Pasadena, Calif. creates imagery using data from the Atmospheric Infrared Sounder (AIRS) instrument that flies onboard NASA's Aqua satellite. Olsen created imagery from a satellite overpass during the morning hours today, March 19. He said, "The infrared and microwave images show the early phase of the convection blow-up."
A movie was created using infrared and visible data from NOAA's GOES-13 satellite from March 17 to March 19 at 1740 UTC (1:40 p.m. EST). When the AIRS data was matched with the GOES satellite animation, the blow-up of convection (rising air that forms thunderstorms) appears to have begun around 0245 UTC on March 19 (10:45 p.m. EST on March 18). In the satellite movie, the strong front comes together and resembles an upside-down arrow at the end of the animation on March 19.
GOES-13 is operated by the National Oceanic and Atmospheric Administration and the movie was created by NASA's GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md.
"The line on the Eastern edge of the active region is well established by the time of the AIRS overpass images (at 0853 UTC on March 19)," Olsen said. In the AIRS infrared image, strong convection (strongest on the eastern/leading edge) and cold cloud tops extend from Midland, Texas over the Texas Panhandle and Western Oklahoma and Kansas. The AIRS infrared image on March 19 at 0853 UTC (4:53 a.m. EST) showed cloud top were colder than -63F/-52.7C, indicating strong, high thunderstorm cloud tops that reached high up into the troposphere.
The NASA microwave imagery showed that the strongest convection and likely heavy precipitation was taking place in Oklahoma, just to the east of the Texas/Oklahoma border North of where I-40 crosses that border.
Severe weather is expected in that part of the country over the next couple of days and NASA and NOAA satellites continue to provide forecasters with valuable data.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
