Marine Weather and Tide Forecast for Fair Plain, MI

DISCUSSION
Issued at 239 AM EDT Fri May 23 2025

A seasonally cool pattern will continue into the middle of next week as an upper level trof and associated upper low remains over the Upper Great Lakes region into Hudson Bay. Low temperatures this upcoming night should dip into the upper 30s near and north of the Michigan border. After coordination with Mich offices, added patchy frost in these areas with lows expected to reach down to 37F this upcoming night. Preferred the GFS solution over the ECMWF as the EC has had major issues with run to run consistency handing the energy downstream (developing a deep cutoff low by the middle of next week) of the blocking ridge. Otherwise, with the weak upper level ridge building slowly (per GFS) over region, temperatures should warm very gradually this upcoming week and be close to normal by Friday. Highs by the end of the week should be in the mid 70s.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/
Issued at 616 AM EDT Fri May 23 2025

A small pocket of 3500ft stratus has developed over the past couple hours, perhaps due to lake-modified air moving inland in conjunction with an upper-level vort max. Additional stratus is noted upstream which will will move through over the next several hours. Sunshine is expected otherwise with a diurnal uptick in wind. Late tonight, prior to sunrise, there could be an additional push of stratus moving inland from the lake impacting KSBN as northwest flow prevails aloft. This will need to be monitored for future TAFs.
