A multi-day severe weather event is expected Saturday, Sunday, and Monday across the Central U.S., as a strong low pressure system will spawn supercell thunderstorms capable of generating large hail, damaging winds, and a few strong tornadoes. The most dangerous day appears to be Sunday, and NOAA's Storm Prediction Center (SPC) has issued their "Moderate Risk" forecast of severe weather over portions of Arkansas , Oklahoma, Texas, and Louisiana that day.
The action will begin Saturday afternoon along a swath from Central Texas northwards into Oklahoma and Kansas, but at present, Saturday's threat warrants only a "Slight Risk" classification from SPC. This weekend's severe weather outbreak has the potential to be the most dangerous one of this relatively quiet 2014, which has yet to spawn a killer tornado.
The relatively cool and dry weather across Tornado Alley so far this year has led to no EF-3 or stronger tornadoes as of April 24, which is a record-long wait since modern tornado records began in 1950.
According to tornado historian Tom Grazulis' book, Significant Tornadoes 1680-1991, "serious efforts" to document all tornadoes began in 1953, which was the first full year of tornado watches issued by the U.S. Weather Bureau, now the National Weather Service.
