Low pressure spinning south of Chicago early this afternoon has left a pretty thick cloud deck across much of northern Illinois and southern Wisconsin. However, if you look to the west I bet you'll be able to see a little blue sky on the horizon. There is a fairly sharp cut-off as to where the cloud cover is and where skies are completely clear. Temperatures under the sun have warmed into the upper 60s to near 70 degrees while under the cloud cover we're stuck in the low 60s. Not that great of a change but it's making for a fairly blah day across much of north-central Illinois.
Once this low moves into Michigan winds will shift around to the southwest ahead of a fairly strong October storm system currently in the northern Rockies. A strong cold front will move through by Thursday afternoon with temperatures ahead of the front warming into the low to mid 70s but dropping quickly once the front passes in the evening. Snowflakes are already flying in Montana right now where Winter Weather Advisories have been issued. A Winter Weather Advisory has also been issued for most of central and western North Dakota while a Winter Storm Watch has been issued for a few counties in eastern North Dakota and northern Minnesota. It's there were a few inches of snow, yes snow, may fly by Thursday afternoon. While we won't see any snow the temperature will drop dramatically by Thursday night as some of the coldest air since very early spring arrives for the weekend.
