Grand Marais Trail Report – 12/11
GRAND MARAIS UPDATE via Grand Marais Tavern – 12/11
GMSTA trail boss grooming update: I have had a lot of questions and inquiries on if we are grooming, when we will be grooming, and why we are not grooming, etc. Before I get into the scheduling I just want to give you all some insight to how we determine when and how much we groom.
Of course one of the biggest factors is weather. How much snow, temps, conditions, what snow quality etc. Just because it’s below 32 degrees doesn’t mean you groom. If the snow quality is poor, sugary not packy, then grooming that type of snow when the base is not set up does very little for the overall "condition" of the trail. You cannot get all the woops/moguls out and the sugary snow just blows back out of the trail as the snowmobiles go over it. If this is the scenario, and it is early in the week with very low traffic, this would be the time to take a day off.
The other big factor is the budget we have to groom for the entire season, Dec. 1st – Mar. 31st. One never knows how much snow we will get over the course of the snowmobile season, as proven last year. The season lasts 121 days, and we want to make sure there is enough budget to get us through the entire season. Budgeting is critical and plays a huge part in the decision of when not to groom. If the budget allowed, we would groom every day weather permitted.
The next consideration is traffic volume. Usually Tuesday -Thursday is the slowest part of the week for traffic. Those are the first days we consider to not groom, as there is the least amount of traffic. This coupled with weather, snow conditions, and budget all help to make the call to groom or not. High travel times, we strive to groom every day to give you the best trails possible.
We will be grooming this afternoon, starting with our East trail, trail 8, and our South trail, 443 & 88 from the park and ride on M77 east to 443. Then once they get back, we will head out on the West trail, 8, 89, 43/88 across Sunrise Landing to the south end of 888 and our North trail 8, from the split at 89, 888, and 88 all the way down to the park and ride on M77. The town route is usually done in coordination with the North run and or run as needed, as it is the single groomed trail route into the town of Grand Marais for food, gas, etc.
Our scheduled grooming times are the same every day with the North and West trails being done early mornings, departing the groomer barn approximately 2am, returning approximately 9am. The East and South trails departing the barn approximately 5pm returning approximately 1am.
Hopefully the snow that is in the forecast will come, and we will have the trails good and ready for a great sledding weekend. We want to thank everyone for your support, patience, and understanding. Thank you also for your comments and info from out on the trails. Your feedback is greatly appreciated.
Last but not least, I also highly recommend downloading the Groomer Tracker app and for $10.00 download the GMSTA trails so you can follow the groomers in "real time". For $10.00 each, you can download the Curtis Area Trails, Seney Snowmobile Association, Tahquamenon Area Snowmobile Association, Chippewa Snow Chasers, and the Sault Ste. Marie Snowmobile Association and see all the trails that are being groomed in the EUP! Other club trail systems are also available for purchase as well as other States. A percentage of the $10.00 goes directly to each club who’s trail system you download. This helps and we greatly appreciate it. Take a minute and check it out.

NEWBERRY AREA UPDATE via Trails End Lodging >> Good afternoon!
Here’s a current look at 1:10 pm in Windy Corners. Currently about 39 light rain and mist falling!
Temps will dip this evening with a return to snow! #newberry #snowphotos
WEATHER UPDATE via Michigan Storm Chasers >> Lake effect totals through Friday afternoon, December 19th, 2025 have been updated slightly to account for latest shifts in atmospheric conditions.
Discussion
As temperatures fall early Friday, moisture pools back in, mixed with colder air over the warmer lakes, turning on the lake effect machine for both of the Great Lakes that influence our normal lake effect zones. A respectable 1-3" to 2-5" is possible in the fairly typical areas shown on the map. The narrow lane of higher elevation across the Keweenaw Peninsula and Porcupine Mountains are most-likely to experience totals exceeding 6". You may have noticed our one main change was the expansion of T-1" over to the east side of the state just as a general precaution to any snow squalls that make it across the state. Not everyone will get a rogue snow squall, but it is in the odds for nearly everyone. A snow squall is a thin, but intense band of quick snow that can produce at least half an inch of snow in minutes time, while knocking visibility down from 10 miles, to a quarter mile in moments time. Additionally, a quick coating of snow may hide any ice that was able to form from the freeze later tonight. Lake effect snow and snow squalls are poised to start later this evening around 8 pm EST (earlier for the western UP), and run primarily through 1 pm EST Friday. A couple lake effect bands may last through 6 pm across northern Michigan near Gaylord, and the central UP near Munising.
Each area is never guaranteed the totals shown on the screen. This is why we call it a prediction. The totals that are shown however do have the greatest odds of occurring. Yes, we are still trying to find that crystal ball, but no luck to this point. Follow us here at Michigan Storm Chasers for forecast updates, and a little humor on the side, throughout the next few days, and as always, 365 days a year! #miweather #keweenaw #westernup #marquette #munising #seney #newberry #soo #straitsarea #gaylord #cadillac #benzie #traversecity #petoskeyLake effect totals through Friday afternoon, December 19th, 2025 have been updated slightly to account for latest shifts in atmospheric conditions.
