Severe weather threatens much of the Plains, South and Midwest Monday through Wednesday. More than 25 million people are under severe storm threat as of Monday night in parts of Northeast Texas through the Mid-South. A higher risk, level 3 of 5, for severe weather includes Fort Smith and Jonesboro, Arizona. Among the main threats are “large to very large hail, damaging winds and some tornadoes,” according to the Storm Prediction Center. A weather system moving west this Monday will trigger severe widespread thunderstorms. And the biggest tornado threat is anticipated for Tuesday and Wednesday. Tuesday’s threat area spans parts of the central and southern Plains to the middle of the Missouri Valley. Very large hail, damaging winds and tornadoes, some possibly strong, will be of concern Tuesday. The cities most at risk for severe weather are Dallas, Texas; Oklahoma City, Okla.; Kansas City, Missouri and Omaha, Nebraska. The severe storm threat for Wednesday is moving east. So that includes much of the Mississippi Valley and the Midwest, with Indianapolis, Memphis, St. Louis, Shreveport and Little Rock most at risk. Major concerns will again include very large hail, damaging winds and tornadoes, some possibly strong.
