This morning ahead of a cold front, showers and storms are stretching from western Missouri through Iowa and into northwest Illinois and Wisconsin. Areas in Jo Daviess County and Stephenson County, along with Green and Rock Counties in southern Wisconsin all dealing with shower and storm activity.
The rain in these areas won't last too much longer this morning, mainly through about 10am and will stay mainly contained along the Wisconsin border and north of a line from Freeport to Rockford. Overall the severe threat in any storms is very low, but tracking small hail potential in the far northwestern corner of Green County in Wisconsin. Also, with dew points in the low 60's along the border, some heavier downpours possible.
There will be many dry hours this afternoon, until the cold front passes later in the afternoon. This will allow for a higher coverage in showers and storms closer to the 3/4pm hour. As the cold front passes scattered showers and storms will continue through this evening. The rain comes to an end just after midnight, with a lingering shower possible Wednesday morning. High pressure then builds in behind the cold front and we dry out through Wednesday and Thursday.
