NEAR TERM. (Today through Tonight) Issued at 228 AM EST Sun Jan 24 2021

Impactful weather: Generally light snow . but with some enhancement across western areas of Chippewa and Mackinac counties of eastern upper.

Pattern synopsis and forecast:

Relatively shallow mid level ridging was starting to push east of the region early this morning, while upper troughing was seen in the central provinces down through the nrn Plains. An associated area of sfc low pressure was moving into western Ontario, which had a cold front that extended south through the Upper Midwest and Central Plains. Light to moderate snow was out ahead of the sfc low and cold front due to increased DPVA and mainly a large area of theta-e convergence on the nose of a 30-35kt LLJ. Strongest total atmospheric forcing/deep layer -divQ was just ahead of the sfc low itself. Further upstream, sfc high pressure and much drier air was in Saskatchewan down into the Dakotas.

The upper troughing and sfc low pressure move into nrn Michigan today, which will be followed by the cold front this evening. The aforementioned DPVA/theta-e convergence spreads in through this morning, before weakening and departing later today into this evening. This will bring relatively light snow, moderate at times, to most of nrn Michigan. The snow is expected to fall apart during the afternoon, as the main upper troughing swings through Lake Superior.

The better accumulations will likely be out across the western CWA, especially in western sections of Chippewa and Mackinac counties of eastern upper. This is where there will be a decent period of lake enhanced snowfall this morning into early afternoon, due to cold low level temperatures, southerly winds/good fetch length off Lake Michigan, and inversion heights up around 6000-6500 feet. This really doesn't last too long, as the deeper moisture strips out aloft later today, and inversion heights will crater pretty quickly through this evening behind the cold front, when the much drier air will be moving in. Regardless, a period of pure lake effect snow is expected through evening, but this snow will get fanned out as low level winds veer from southerly to west then NW over this time. The activity really wanes through the overnight.

Total snowfall will range from 1-2 inches across NW lower, a half inch to an inch across NE lower. In eastern upper, a general 1-3 inches is expected with localized amounts up to 4-5 inches in western Mackinac county. Will likely need an advisory there, which would line up well with the advisories from MQT, just to the west.

Highs today will generally be in upper 20s to around 30F. Lows tonight will mostly be in the teens to low 20s. Fcst soundings are trying to show some potential clearing overnight, that could lead to colder overnight temps in spots. However, am not holding much stock in that attm since we will be well cold enough for lake effect clouds to hold on most areas.

SHORT TERM. (Monday through Tuesday) Issued at 228 AM EST Sun Jan 24 2021

. Snow chances late Monday night into Tuesday .

High impact weather: None is expected at this time.

Primary forecast concerns/challenges: Pops through the period.

Perhaps some light northwesterly flow lake effect across eastern upper Monday morning, otherwise a nearly zonal flow aloft should lead to quiet weather during the day Monday. Attention will then turn to an area of low pressure moving by to our south. Latest and recent ensemble guidance has trended this system a bit farther to the north. In addition, there could be a little lake enhancement off of Lake Huron due to northeast winds. Therefore, have pulled slight chance/low chance pops into the northern two-thirds of northern lower for overnight Monday into Tuesday. Later shifts will obviously be watching for any further changes in the model guidance. Temperatures will generally be a little above normal through the period.

LONG TERM. (Tuesday night through Saturday) Issued at 228 AM EST Sun Jan 24 2021

. Minimal Weather Concerns with Milder Temperatures .

High impact weather: None is expected.

Northern Michigan still looks like it will be between systems moving by to the south and to the north. This setup if it holds true would lead to an extended stretch with little if any sensible weather. Temperatures are expected to start off near normal but then moderate to a little above normal once again by the end of the week into next weekend.

AVIATION. (For the 06Z TAFS through 06Z Sunday night) Issued at 1151 PM EST Sat Jan 23 2021

VFR conditions will give way to lowering cigs as upstream weak area of low pressure approaches and crosses the region this morning. Band of mostly light snow will spread across the taf locations from west to east, likely bringing a period of IFR visibilities. Not expecting much accumulation, perhaps up to 2 inches at western taf locations by the time snow scatters out this afternoon.

MARINE. Issued at 228 AM EST Sun Jan 24 2021

Low pressure will cross southern Ontario today through tonight, and will drag a cold front across northern Michigan. This will bring light system snow to the region, which will turn to lake effect snow showers through the day into tonight. Advisory level southerly wind speeds are expected in most nearshore waters today, with continued advisory speeds over portions of nrn Lake Huron tonight, as winds swing around out of the west then NW. Winds turn more northerly Monday, then NE Monday night. Additional advisory winds will be possible Monday night, with the region stuck between the high pressure and a storm system passing through the Ohio valley.

APX WATCHES/WARNINGS/ADVISORIES. MI . WINTER WEATHER ADVISORY until 6 PM EST this evening for MIZ086- 095-096. LH . SMALL CRAFT ADVISORY from 1 PM this afternoon to 11 PM EST this evening for LHZ346>348. LM . SMALL CRAFT ADVISORY from 6 AM this morning to 6 PM EST this evening for LMZ323-341-342-344>346. LS .
