Cloudy and cool today; clouds and sunshine this weekend.

Cool air will continue to flow into the western Great Lakes region from the north, behind an area of low pressure centered over southern Michigan, and should keep us cloudy with temps just a little below-normal today. There was still some light rain or snow in northeastern Wisconsin this morning, but this should be pushing off over Lake Michigan shortly. The clouds should start to clear out late in the day, and we can expect a mix of clouds and sunshine this weekend and through much of next week. We may see a few isolated rain showers Saturday night, but otherwise our next chance of rain doesn’t look to arrive until next Wednesday night. Our next chance of snow will hopefully be much, much later.
