Marine Weather and Tide Forecast for Menominee, MI

DISCUSSION
Issued at 1153 PM CDT Sun Mar 15 2026

Historic winter storm continues... Following a brief lull in the snow late this evening (including periods of freezing drizzle), we get right back into the brunt of the action as heavy snow has already begun re-developing from the south in conjunction with a mid-level shortwave that has deepened into a closed low over southern Wisconsin. As such, conditions will continue to deteriorate rapidly over the next several hours as 1"/hr snowfall rates enter the Fox Valley and lakeshore areas. Provided a deep DGZ (~12k ft) and ample synoptic support, snow should be able to accumulate rather quickly throughout the morning. However, have stuck with lower SLRs since strong winds will likely fracture any larger dendrites. When combined with said northeast winds gusting to 45 mph, there is a high likelihood that blizzard conditions will set in once again, lasting through the morning. When all is said and done, there remains a high probability (50 to 80% chance)
that the Fox Valley eastward will pick up another 10 inches of snow through this afternoon, locally higher. Conditions should then gradually improve by this evening as winds subside and snow winds down. All in all, we remain on track to go down in the record books with a widespread 1 to 2 ft of snow, locally up to 30 inches over portions of far northeast Wisconsin.

Headline considerations... No changes made to the headlines on this shift, with the Blizzard Warning set to go until 4 PM. Main consideration moving forward will be whether or not to cancel the Blizzard Warning early, as some CAMs indicate winds dying down slightly earlier across the northwest portion of the forecast area.

Bitter cold today... Combination of robust northerly flow and 850 mb temps reading -20 to -22C will result in a quick shot of arctic air today, with wind chill readings to -10F across the north, and struggling to hit 0 degrees in/around the Fox Valley.
The cold will not be long-lived as synoptic flow de-amplifies, resulting in weak ridging moderating temperatures back to near normal, and even above normal, by the end of the work week. Highs in the mid to upper 40s will return Thursday into Friday.

Extended... We're not quite done with snow yet, as a couple of transient clipper lows look to bring additional chances for light snow through the end of the work week. The first of these systems, Tuesday into Wednesday, currently looks to take a dive to our south for the most part, though this is wont to change in the next day or two. The second, Friday into Saturday, looks to be more of a classic setup, tracking the surface low over Lake Superior and affecting mainly the northern snow belts.

AVIATION
for 06Z TAF Issuance Issued at 1051 PM CDT Sun Mar 15 2026
