As advertised the past few days, a weak cold front is headed toward the area late tonight and early Saturday, bringing with it a chance for scattered showers. This is not a strong system and with the front arriving late tonight and the wee hours of Saturday, there isn't much instability to work with. Below is a simulated image of the radar for 5:30 Saturday morning from the RPM model, showing a light scattering of rain across the area.
As the front moves eastward, it will have a little more energy to deal with as the day goes on, giving higher rainfall amounts. As for the immediate area, expect a tenth of an inch or less of rain.
Clouds begin to break up later on Saturday, allowing for sunshine to warm temperatures into the lower 70s. We'll clear out Saturday night allowing for a pretty typical fall day on Sunday & Monday.
Better chances for rain come in with a stronger system next Monday night and Tuesday. Right now, it looks like areas could see anywhere from a half inch to an inch of rain. Of course, this system is still a few days out so there will be plenty of time to hammer out the details. We really could use a decent soaking across eastern Iowa and western Illinois.
