The Storm Prediction Center has issued yet another high risk area for severe weather, meaning a 30% chance for a tornado within a the area highlighted area. Joplin, the Missouri city hit by nealy 200 mph winds in the southwestern part of the state, received an F4 tornado approximately 1/2 mile wide that took a direct hit, tracking more than 6 miles through Joplin. This one tornado killed over 100 people, making it the deadliest single tornado since the 1940′s.
A large negatively tilted upper level low will develop west of the highlighted area and move across Oklahoma, Kansas, Missouri and Arkansas with the likelyhood of more damaging tornadoes and high winds.
Closer to home, we will finally see our ridge of high pressure that has been keeping us unseasonably hot and dry, break down beginning Thursday. This will increase our humidity levels and cloud cover, but we will see slightly cooler temperatures and afternoon rainshowers returning.
Afternoon highs will scale back to the upper 80′s by Friday, and we will have cooler afternoons and evenings.
