An occluded front approaches from the west/southwest tomorrow and crosses the region Thursday night into Friday morning with rain expected through the day. Rain tapers to showers overnight into Friday morning.

High pressure in the Midwest starts to build in Friday with clearing skies in the afternoon along with cooler temperatures for the weekend. Clouds increase Sunday night as a low-pressure system moves east from the Great Lakes with rain Monday night into Tuesday morning. Rain may mix with snow Tuesday morning.
