Rain and much cooler temperatures behind a cold front will bring a feeling of fall to the east coast today. In addition, an active fall storm pattern developing in the Pacific Northwest this week will bring areas of heavy rains, and very high elevations could receive heavy snow. Wetting rains to the valley floors will spread south Thu and Fri into northern California,where active fires continue. Read More >

Radar loop of storms in Southwest Arkansas
Radar imagery of the two storms that moved across Southwest Arkansas. Notice the storm that splits in Bowie County, TX. The left part of the storm moves to the northeast through Little River, Sevier, and Howard Counties at around 80 mph! Farther northward is a tornadic supercell which developed over McCurtain County, OK, and cut a track across northern Sevier and Howard Counties, before moving into Pike County. This storm exhibits the class "hook echo" on its southwest end, a feature common to tornadic thunderstorms.
 
Loop of radar velocities for the storms in Southwest Arkansas
Radar loop of storm-relative motion, which measures rotation in a thunderstorm relative to the radar. Green and blue colors indicate air indicate air moving toward the radar, while red and pink colors indicate air moving away from the radar. The brighter the color, the faster the air is moving. In this imagery, where the pinks and blues are very close together is where the tornado is occurring. Most tornadoes rotate counter-clockwise, as is the case with the northern storm. Air is moving toward the radar on the left side of the image, and moving away from the radar on the right side.

Now, look at the southern storm, which is moving rapidly from the bottom-left to the top-right of the imagery. Notice the blues are on the right side and the reds are on the left side. This is imagery of a rare clockwise-spinning, or anticyclonic, tornado.
