More rain is expected across the Great Lakes as a cold front moves through the region. A low pressure system moving eastward through Canada continues pushing a cold front through the Upper Midwest and Great Lakes. This will produce more rain showers across the Great Lakes, with periods of heavy rainfall anticipated along the downwind shores. Cold air, meanwhile, will continue to pour in from Canada behind this system, allowing for cooler temperatures to linger across the Northern states. Expect overnight lows to dip into the lower 30s again Thursday night across northern Minnesota, northern Wisconsin, and the upper peninsula of Michigan. This NOAA satellite image taken Thursday, Sept. EDT shows a stationary front across northern Florida with showers and a few thunderstorms. A cold front is moving through the Great Lakes with a line of showers and thunderstorms. On the back side of this system, dry conditions will persist across the Northern Rockies and Northern Plains. These areas will continue to see dangerous fire weather conditions. Red flag warnings will remain in effect in these areas. In the East, a ridge of high pressure continues to build across the Eastern valleys. This will bring another dry day to most of the East, with temperatures slowly returning to seasonable. Showers and thunderstorms will persist across Florida as the tail end of a cold front slowly moves further into the Atlantic Ocean. Temperatures in the lower 48 states ranged Wednesday from a morning low of 26 degrees at Stanley, Idaho, to a high of 102 at Palm Springs, Calif.
