Good news. The weather geeks are reporting a change in this bizarre weather pattern. I rely on a blog called Category 6 at Weather Underground and these people stay on top of whats happening and have been very accurate. From today’s “Another Day of Severe Weather Kills Two, But a Pattern Change is at Hand” :
NOAA’s Storm Prediction Center (SPC) logged 24 preliminary reports of tornadoes across four states on Wednesday, along with 45 reports of large hail and 210 reports of high winds. That brings the total number reported (not confirmed) tornadoes since May 17 to 402, and the total number of tornado, large hail, and high wind reports to 2779–an astonishingly high number of severe weather events for a two-week time span.
caused by an unusually cold and persistent upper low in the western U.S. combined with a strong ridge of high pressure that brought record May heat over the Southeast U.S. A powerful jet stream ran south of the upper low and north of the high, bringing energy and spin to the thunderstorms that formed each day, thereby creating spinning supercell thunderstorms that spawned tornadoes. This pattern is weakening and shifting, which will allow the Southeast U.S. to cool, the Western U.S. to warm, and the Midwest U.S. to experience dryer and less stormy weather.
