Severe Weather Outbreak in the USA – April 27th, 2014

A severe weather outbreak occured in parts of central USA last night, more precisely across parts od Nebraska, E Kansas, E Oklahoma NE Texas, Missouri and Arkansas. Several tornadoes occurred, including a strong wedge tornado resulting in significant damage in the town of Mayflower, Arkansas. Storm Prediction Center (SPC) has issued a rare high risk for W-CNTRL Arkansas where conditions were very favourable for violent tornadoes. However, more tornadoes actually developed outside the high risk area as can be seen from the preliminary reports.
