- Upper Low brings showers and even wet snow tonight

An upper low moves through followed by push of cold air tonight which could bring the first snow to the northern forecast area by Friday morning. Above freezing skin temperatures should prevent accumulations except for the higher elevations of Osceola and Clare Counties where a coating of slush is possible. No travel impacts are expected.

- Northerly flow lake effect rain showers Friday

Lake effect rain showers in north-northwest flow on Friday will affect areas close to Lake Michigan with the highest POPs in southwest Allegan and western Van Buren Counties. The rain will be diminishing and ending Friday night as shortwave ridging moves in. Cyclonic flow returns over the weekend but fair weather continues as a clipper passes far to the north of Lower Michigan.

AVIATION /00Z TAFS THROUGH 00Z SATURDAY/

Issued at 629 PM EST Thu Nov 5 2026

A cold front moving across Lower MI will switch the winds from west to NNW tonight. Radar shows light showers moving south across the region and we'll see some move across the terminals during the next several hours.

Cold air flowing over the lake will generate some lake effect rain showers Friday, especially closer to the lake shore. Otherwise, generally MVFR conditions are expected, with spotty IFR vsbys in showers this evening.

MARINE

No changes to the marine hazards forecast for tonight with low end northerly gales at times persisting into Friday afternoon. Wind fields may be slightly too strong for waterspouts, but they are a possibility Friday morning when the mid/upper cold pool moves across the lake.
