A cold front is poised to begin pushing east today across the Upper Midwest, bringing some unsettled weather to the region.
Behind the front will be an almost autumnlike air mass, both cool and dry, however the change will not come quietly for many. Strong thunderstorms are set to ignite along the front, bringing severe weather to area residents.
The reason for the severe weather? The northern Plains will be a battleground between two well defined air masses. The cool shot of air in the wake of the cold front will be driving through warm, moist air moving north across the central Plains. The collision may turn violent for some.
Strong storms will rumble across area cities, including Minneapolis, Minn., Sioux Falls, S.D., Madison, Wis., Rapid City, Iowa and Omaha, Neb., among others.
Damaging winds will be the primary threat from storms across the region, as storms will likely transfer stronger winds aloft down to the surface. Hail, along with heavy downpours, could also threaten area residents as storms pass through the area.
Along with the above threats, thunderstorms will bring dangerous cloud-to-ground lightning with them. This means any thunderstorm across the region could be potentially dangerous, and area residents will want to seek shelter when storms approach.
As the cold front shifts east on Thursday, big population centers will come under fire from similarly strong storms. Among the places in the storms crosshairs include Kansas City, Mo., Saint Louis, Mo., Chicago, Ill., Indianapolis, Ind. and Detroit, Mich., among others.
While lulls in tropical activity in the Atlantic will continue, a rapid end to the hurricane season in September does not always occur during an El Nino.
After heat has dominated headlines this summer, cool air has finally taken control of the northern half of Europe with no signs of departing anytime soon.
Steering winds could take Ignacio, as a remnant storm, into the southeastern arm of Alaska or British Columbia during the middle days of next week.
While Tropical Storm Kevin will stay well away from Mexico, its moisture will still lead to an increase in showers and thunderstorms from Baja California to the Four Corners region of the United States.
A stormy weather pattern will prevail through September across much of southern South America.
Downpours will spread from Italy to Ukraine to start the weekend before cooler air works southward and eventually sweeps the heat wave away from the Balkan Peninsula.
