- Upper Low Moves East with Rain showers ending tonight

Lake effect rain showers will taper off overnight as the upper low moves east followed by height rises and general subsidence for the weekend with fair and cool weather through Sunday. A clipper will move north of Lower Michigan on Sunday but deep moisture and precip will remain north of the forecast area. Fair weather continues through the middle of the week in fast quasi-zonal flow.

- Another Upper low and showers late week

A northern stream shortwave trough tops the western CONUS upper ridging and digs out a longwave trough across the eastern CONUS by Thursday then merges with upper low over eastern Canada. The resulting height falls across the Great Lakes region will result in cooler temperatures with lake enhanced showers by the end of next week.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 628 PM EST Fri Nov 6 2026

We will remain under mostly cloudy skies on the back (west) side of a slow-moving low pressure system until Saturday afternoon. Currently a mixture of MVFR and VFR ceilings should deteriorate to widespread MVFR tonight as a lobe of lower clouds and light precipitation pivots through from the north. Clouds are favored to scatter out from west to east during Saturday afternoon as high pressure noses in.
