KEY MESSAGES
- Upper Low Moves East with Rain showers ending tonight
- Another Upper low and showers late week
DISCUSSION
Issued at 205 PM EST Fri Nov 6 2026
- 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 /06Z TAFS THROUGH 06Z SUNDAY/
Issued at 1241 AM EST Sat Nov 7 2026
We are starting off this forecast period with widespread low clouds over the area. These clouds are mainly MVFR with a few breaks of VFR conditions. We expect the MVFR conditions to continue into the early afternoon hours, before drier air replaces the clouds and everything goes VFR as the clouds break up.
Eventually most locations will see some clearing by evening. This will continue through the end of this period at 06z Sun.

MI...None.
MARINE...Small Craft Advisory until 11 AM EST this morning for LMZ844>846.
