Marine Weather and Tide Forecast for Maple City, MI

DISCUSSION
Issued at 149 PM EDT Sun Apr 19 2026

Deep, longwave trough pivots east of the Great Lakes through Monday with 850mb thermal trough gradually giving way to warming temperatures from the west. Upper troughing pushing into the Pacific NW will bring higher heights and more pronounced ridging toward the Midwest/Great Lakes for midweek. More active weather will return to Michigan by the end of the week into the weekend as that Pacific NW trough pushes eastward into the northern Plains.

A few lake effect snow showers gradually ending tonight in northwest flow areas. Otherwise, a very cold night (by later April standards)
with lows in upper teens to middle 20s. A weak mid level shortwave may clip parts of eastern upper with an isolated shower later Monday and Monday night, quiet conditions elsewhere across northern Michigan as higher heights to our west begin to make a push eastward.

Several days of dry weather expected through midweek with seasonably mild temperatures (50s and 60s). The pattern turns more active by late week as shortwave energy ejects out of the western CONUS trough and pushes into the center of the country. This will eventually push much more moist air into the Great Lakes (PWATs nearly 150%+ of normal), introducing the possibility of rain to end the week.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/
Issued at 107 PM EDT Sun Apr 19 2026

VFR conditions through the period. FROPA moving through northern lower from north to south this afternoon. N/NW winds of 10 to 15kts with G15 to 25kts through 02z. Skies generally BKN040 with ISO -SHSN moving over some terminals. Winds diminish overnight, with G15kts starting up near the end of the period for some terminals (KTVC/KPLN/KMBL).

HYDROLOGY
Issued at 155 AM EDT Sun Apr 19 2026

Current flows across area rivers remain anomalously high, with plenty still exhibiting cfs values at a 2% annual exceedance probability (or 50 year average return interval). Combining this with some of our flood inundation mapping tools suggest inundation still occurring across portions of northwest and northeast lower MI (for example portions of Cheboygan, Alpena, and Wexford counties).
Some improvement noted across other locales though standing water likely remains in poor drainage places and areas of saturated soils.
Thus, areal and river flooding is still occurring, although river levels and flows are dropping to some extent across the area. This will continue to be the trend through a good portion of this upcoming week as a dry period is expected, so we should expect a slow but significant improvement in the ongoing flooding and subsequent river levels across northern Michigan, as indicated by the latest HEFS River Flood guidance. Flooding will linger longer across the Tip of the Mitt and any lakes that have elevated water levels that are impinging on houses. Worth noting that an active period is likely late this week and beyond, with the potential for noteworthy precipitation. Something to consider moving forward.
