The first low will track through the Upper Midwest Monday night and then the second wave will cross the Middle Mississippi and Ohio Valleys on Tuesday. Falling temperatures behind the front will make snow a possibility on the back edge of the precipitation. A wide swath accumulating snows are expected across portions of the Upper Midwest as well as along the Colorado Rockies...while sleet and freezing rain will possible over parts of the Kansas and Oklahoma. Shower and thunderstorm activity will continue over Florida the next few days while a wavy frontal boundary lingers off the East Coast.
