An active pattern is setting up across the southern Plains and Mississippi Valley this week for the potential of severe thunderstorms. The Storm Prediction Center has a risk for nearly every day. A strong, digging Jet Stream coupled with a slow moving front will be the focus for storm development. Abundant humidity flowing in from the Gulf of Mexico along with warmer temperatures will help to fuel severe storms this week. The Storm Prediction Center upgraded the outlook and there is now an enhanced risk for severe thunderstorms for Monday. https://www.facebook.com/WeatherNation/posts/10156374003344874 The tornado potential is low today due to weak low-level wind shear. Large hail greater than an inch in diameter and strong wind gusts higher than 60 mph are the more significant severe weather threats.   The severe weather risk area shifts slightly southward on Tuesday from the Arklatex to the Mexican Border. As the cold front slowly pushes to the south Wednesday, the threat region moves to along the Gulf of Mexico from Texas to Mississippi. The Jet Stream will remain strong and humidity levels high for Wednesday into Thursday, keeping the severe weather threat in the forecast.
