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.
Tropical Depression Two has formed in the Atlantic and could become the next tropical storm of the season by midweek.
Warm and humid air in place over much of the Midwest and Northeast at midweek will contribute to the risk of drenching, gusty and locally severe thunderstorms on Wednesday.
After temperatures briefly climb to typical midsummer levels, another cooldown will roll into the Midwest and expand to the East for the last part of July.
Severe storms will fire up Tuesday afternoon and evening, threatening outdoor activities and travel for many.
Powerful winds, heavy rainfall and dangerous mudslides will threaten Taiwan on Wednesday as Matmo moves across the island.

Christopher Columbus' third voyage. After leaving the Cape Verde Islands, the 4 ships drifted WSW in the equatorial current. "The wind stopped so suddenly and unexpectedly and the supervening heat was so excessive and immoderate that there was no one who dared go below after the casks of wine and water which burst, snapping the hoops of the pipes; the wheat burned like fire; the bacon and salted meat roasted and petrified."
