After a quiet weather weekend over the Plains and East, the weather will get more active beginning Monday with severe storms set to fire over parts of the central Plains.
A frontal boundary will slide into the Plains and set up across northern Texas, central Oklahoma and eastern Kansas on Monday.
Drier air from the north will clash with very warm and muggy air from the south, creating a battle zone over the eastern half of Oklahoma, southwestern Missouri, eastern Kansas and far north-central Texas Monday.
Cities including Oklahoma City and Tulsa, Okla., along with Wichita Falls, Texas, and Springfield, Mo., will have the highest risk of strong to severe thunderstorms Monday. The threat will primarily occur during the afternoon and evening hours.
The greatest threats will be isolated large hail to the size of golfballs and a few damaging wind gusts to 60 mph.
As the nighttime hours progress, leftover drenching thunderstorms will spread east and northward into the northwestern Arkansas and central Missouri.
Have a plan of action ready before the storms develop. Know what to do when severe weather is heading for your area.
As always, heed all severe weather watches and warnings and be prepared to take action when severe weather threatens.
