Munising Area Trail Report – 01/21
MUNISING AREA UPDATE via Alger County SORVA >> 01/21 Trail Report Posted Sorry for the lack of reports. PC died after a windows update over the weekend. We groomed non stop all weekend. I assure you. Last night (Monday Night)we did not send the groomers out due to the Extreme Cold. This morning 5 am we tried to send them out. Our fuel is gelled up. We are currently working to get them back on the trail. Posting a bunch of pics from over the weekend. We had several issues and worked through them in nascar pitstop fashion. Cutting mogs North of Shingleton we broke the drag. Wing was stuck down and could not cross the bridge. This set us back 4 hours but was able to rig and groom the rest finishing Sunday morning 8am. The bison has a frozen solid air filter. The fine dust snow was not only bad for visibility. Tractor air filters suffer as well. Doing all we can. Sorry the trails are hammered right now. <> <> <> REGIONAL TRAIL REPORTS Visit Alger County SORVA Facebook Page >>>> <> Visit Alger County SORVA Trail Report >>>> <> Visit TNT Trenary Northern Trails Facebook Page >>>> <> MUNISING AREA UPDATE via Munising Motor Sports >> So we had some freezing rain overnight but it's changed to snow now!!!

Discussion
The north side of the low will have much colder air, and the deformation zone for this event will be set up across the eastern UP and Lake Superior region. Totals greater than 1" of snow (some melting) will be confined north of M-55 to the Mackinac Bridge, while totals closer to the 3"+ mark are confined from St. Ignace up to Paradise and Sault Ste. Marie. Additionally, the Keweenaw Peninsula also may see the highest snowfall totals too.
You may have noticed that we added a new color for this event only. Because there is a gradual change from rain to snow... freezing rain, and even sleet is expected with this event. Sleet is like the shared sibling between snow and freezing rain. Sleet is snow that melted to rain really high up immediately after falling from the clouds, but spent enough time in the cold sector after melting to reform into tiny pellets. Freezing rain, however, forms when there isn't enough time for the rain to reform back into those tiny ice pellets due to that warm sector close to the ground, but because the ground itself IS a cold sector, it freezes on contact. Yes, sleet is slippery, but due to its properties, it's not quite as impactful. Still, because of the sleet's size, it accumulates in tenths of an inch similar to snow instead of hundredths like freezing rain. As a result, much of the white trace-1" corridor will likely fall as <1" of both snow and sleet. Again, not a huge amount, but worth mentioning. Timing for this snowfall will be similar to that of the ice. Anytime from 6 am EST Friday through the end of the day Friday is the expected duration.
Winter weather advisories are now in effect for the eastern UP regarding this snowfall. We will have traffic impact maps and timing maps coming later this afternoon after our Christmas morning activities. See you all back here soon!
