For a couple days it almost felt like spring had arrived, but it looks like we have fallen back into the late February/early March regimen experienced the first 10 days of this month. Thursday’s 70s did occur in many locations south of Interstate-80 Friday, but by the end of the day the east-west oriented frontal boundary separating the warm air from the 40-degree chill to the north was sinking farther south.

Saturday looks to be a cold raw day, as low pressure deepens over the central plains. We should experience chilling rains, heavy at times, while Wind and Lakeshore Flooding Advisories will be in effect. East to northeast winds will ramp-up almost area-wide, gusting to as much as 50 mph, building 10 to 16-foot waves over the southern portion of Lake Michigan which in turn will cause flooding along the Illinois shoreline.
