- 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.
