Marine Weather and Tide Forecast for Beechwood, MI

DISCUSSION
Issued at 330 PM EST Mon Jan 19 2026

- Hazardous Travel Conditions into Early Tuesday Morning

A slow downtrend in the hazardous conditions is expected through tonight, as the worst of the winds and visibility is now past. West wind lake effect snow will continue along with pockets of blowing/drifting snow overnight, good for another 0.5 to 3 inches area-wide, bringing storm totals (not counting drifts) in the warning area to over 6 inches in many areas, and perhaps up to 14 inches between Holland and Grand Rapids where a narrow belt of 6 to 9 inches fell last night. Totals in central and south central Michigan are expected to range around 1 to 4 inches.

Overnight, the air near the ground over Central Michigan may cool and decouple, reducing mixing becoming and a little less windy.
Still, wind chills -10 to -15 F are likely, and a Cold Weather Advisory continues for interior areas along/north of US-10. Mecosta, Isabella, Montcalm, and Gratiot may also come close to a cold advisory.

Lake effect snow will continue overnight, given persisting high instability off the lake surface and inversion heights staying above 5,000 feet, though most snow production should stay above the DGZ, limiting flake size. A weak 500 mb shortwave propagating through the cyclonic synoptic pattern overnight may also throw the lake effect a bit of a lifeline. With central Michigan interior potentially decoupling, low level wind convergence and therefore the main focus for snow will be near and west of US-131, with the exception of a confluence band that could extend farther east toward the Lansing area near or south of I-96.

Travel Tue morning will still be slow and slick given the lingering snow and cold temperatures, but conditions slowly improve during the day with light snow showers.

- Additional Rounds of Snow Wednesday into Friday

The next wave of low pressure along a frontal boundary will roll through Wednesday morning, likely making for another challenging commute. Moisture and lift aloft within the warm air advection (front end) of this system occurring within about a 5,000 ft thick DGZ will contribute to potential half inch per hour snowfall rates leading into the morning commute. A swath of generally 1.5 to 3 inch totals appears favored by mid day Wednesday. 5 inch totals may be possible between Grand Haven and Ludington, where confluent SE/SW flow in the vicinity of the surface low, surface frontogenesis, and a shallow lake effect convective layer could contribute to enhancing snowfall rates near the shoreline. But if the track of the low ends up trending farther south, this scenario would be less of a possibility. Temperatures starting in the teens will rise into the mid 20s, perhaps around 30, during the day, making chemical road treatment more effective.

Lake effect snow showers are then likely to continue late Wed through Fri as progressively colder 850 mb air within the broad cyclonic synoptic flow regime.

- Rare and Potentially Near Record-Setting Cold This Weekend

(Issued at 331 AM EST Mon Jan 19 2026) ECE guidance has been repeatedly indicating a rare bout of truly impressive cold coming our way Friday into the weekend. The Arctic Oscillation (AO) appears to be a major player in the longwave pattern and surface pressure anomalies setting up over the northern United States later this week and weekend. The AO is already negative and is about to drop further into some impressive territory, potentially around an index of -5.
As the AO gets increasingly negative, we typically get increasingly colder. ECE probabilities for 850mb temperatures to drop to -30C or colder are now 80-100% across the U.P. and 60-80% near and north of US 10. Various deterministic runs of the ECMWF and GFS have the -30C isotherm (or colder) pushing through the entire Lower Peninsula.

The ECMWF and GFS push air temperatures at the surface into subzero territory during the day Friday behind an impressive Arctic front that sweeps through late Thursday night or early Friday morning.
Both models are indicating wind chill readings getting down to -25 or colder during the day. By Saturday, ECE mean high temperatures are showing highs around 0F with low temperatures of -10 to -20 across the region. At GRR for example, over 50% of the ECE members show -20 or colder and nearly 20% of the members show -24 or colder, which would tie the coldest reading ever recorded at Grand Rapids.
Plenty could change between now and then but given the rarity and strength of the signal it is important to mention, and temperatures this cold can cause some significant issues to cold water pipes.

Very cold temperatures are shown by the ECE to continue through the weekend and into the following week with additional subzero nightly readings possible. This will be something to keep an eye on with future forecast updates.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
Issued at 1151 PM EST Mon Jan 19 2026

We will be seeing a general improving trend at all of the sites, aside of maybe some drifting snow during the day on Tuesday with a few wind gusts.

The impactful snow showers with MVFR and IFR have generally migrated back to the western terminals of KMKG, KGRR, and KAZO.
This is due to the winds diminishing over the inland areas. The other terminals are seeing a few snow showers, but not as intense as toward the lakeshore. The less wind also is easing up on the blowing and drifting snow that was widespread earlier.

We will see this trend continue through the morning, before snow showers end inland, with some partial clearing taking place.
Western sites will see the snow showers last a little longer, and will see the partial clearing occur later. Toward the end of this forecast period, KMKG will see light snow redevelop as the next wave approaches the area.

For GRR 06z update, snow will slowly and gradually weaken through Tuesday morning. Snow will remain very fine and very dry in nature, with only an inch or so of additional accumulation likely.
Snow should end Tuesday afternoon for a few hours.



MARINE
Issued at 330 PM EST Mon Jan 19 2026

Gales on Lake Michigan are diminishing as expected, and the warning will be transitioned to a small craft advisory no later than 7 PM today. Heavy freezing spray continues through tonight. Winds will be a little less of a factor on Tuesday but still enough for some freezing spray. Hazardous conditions for small craft continue through the rest of the week.
