- Rain showers today, then cooler with Lake Effect rain/snow

Rain showers advancing eastward from Minnesota into Wisconsin this morning are associated with a clipper low/digging northern stream shortwave trough. Expect the rain to move into northwest forecast area this morning then spread to the southeast in the afternoon.

The trough merges with a retrograding upper low over eastern Canada., leading to an amplified pattern across the CONUS through the weekend, with strong northerly flow bringing lake effect rain and snow showers and cool temperatures for Thursday through Saturday. The immediate lakeshore should remain rain due to modification by the relatively warm lake surface temperatures. Inland will see some snow and perhaps light accumulations on unpaved surfaces. Travel impacts are not expected since the heavier lake effect bands are expected to remain offshore.
