A strengthening storm system will produce a major severe weather outbreak over the Plains Saturday. The remnants of the storms could still have damaging consequences in the St. Louis area late Saturday night.
The developing storm system marks an end to the tranquil weather being experienced over much of the nation in recent weeks.
The storm brewing to the west and its stiff southerly winds will then rout out 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 southeastern Minnesota, Iowa and western 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 during the afternoon and evening.
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 late Saturday night. There could be downed tree limbs, minor property damage and sporadic power outages as a result.
Cool, gusty winds will linger Sunday. However, by the afternoon the winds will begin to ease and the sun should come out with temperatures rebounding past 70 degrees.
Temperatures will trend colder through the remainder of 2014 in Minneapolis as fresh arctic air returns to the city.
