The developing storm system marks an end to the tranquil weather being experienced over much of the nation in recent weeks.
Prior to the storm’s arrival, a front will send cool air into the region tonight, which will stick around into Friday.
The storm brewing to the west and its southerly winds will then rout out that cool air during Saturday. With the aid of sunshine, temperatures will soar into the 80s.
During Saturday, building warmth will lead, in part, to severe thunderstorms from southwestern Wisconsin, Iowa and western and central Missouri to north-central Texas. The risks from the storms include damaging wind gusts, large hail, flash flooding and a few tornadoes.
The storms could take aim at the Missouri communities of Kansas City, Joplin, Springfield and Columbia.
The remnants of these storms, with and without thunder, can produce strong wind gusts topping 55 mph and blinding downpours in the St. Louis area later Saturday night. There could be downed tree limbs, minor property damage and sporadic power outages as a result.
Cool, gusty winds will linger for a time Sunday. However, by the afternoon the winds will begin to ease and the sun should come out with temperatures rebounding past 70 degrees.
