NEAR TERM. (Through Tonight) Issued at 202 PM EST Thu Jan 20 2022

. Lingering Light Lake Effect Tonight .

High Impact Weather Potential . Low.

Primary Forecast Concerns . Amount of clearing and resultant low temperatures tonight.

Despite a strong area of surface high pressure (1043 mb) centered over Iowa building in tonight . cold air streaming over the relatively warmer waters of the Great lakes will continue to result in lake effect snow showers tonight. Activity is expected to be light with mean 850-700 mb relative humidity falling from around 50 percent this evening to near 30 percent by morning. Meanwhile, the flow will veer from north northwest this afternoon into the northwest this evening with continued veering into the southwest toward daybreak. Accumulations of an inch or less are expected as inversion heights fall from about 4000 feet to about 3000 feet overnight Meanwhile. there is uncertainty over the amount of clearing in non-lake effect areas. With the surface high centered off to our south believe it will be tough to clear skies out with low level moisture remaining trapped below the subsidence inversion. Therefore have not tanked temperatures but if it does manage to clear we will likely be well underdone with how cold it gets. Forecast lows tonight range from the single digits above zero near the lakeshores to the single digits below zero inland.

SHORT TERM. (Friday through Sunday) Issued at 202 PM EST Thu Jan 20 2022

. Accumulating Snow Saturday .

Pattern Synopsis/Forecast:

Rather persistent pattern, consisting of eastern Pacific ridge and broad eastern NOAM troughing, set to continue through the foreseeable future. This favors a continuation of near to below normal temperatures and rather moisture starved, fast paced systems in continuous upper level northwest flow.

Primary Forecast Concerns/Challenges:

Addressing lake enhanced snow potential as next "clipper" type system visits the northern Michigan on Saturday.

Details:

Relatively uneventful weather Friday through Friday evening as low level winds back, resulting in light southwest flow lake effect snow showers. Subsidence and lack of moisture above 900mb will inhibit accumulations, with 1-3" amounts possible in western Mackinac County. Temperatures will run at least a few degrees below normal, with highs mostly in the teens and lows in the single digits . both above and below zero.

Next clipper system set to arrive later Friday night into Saturday. Per the usual with these Canadian originated systems, moisture advection will be very limited . with the "synoptic" portion of the snow event remaining minimal. However, pre-system environment will remain plenty cold enough to produce a good lake moisture contribution. Expect initial southwest flow enhancement ahead of the cold front, with enhancement continuing as winds steadily veer through the frontal passage. Pattern recognition strongly supports good snowfall rates during this period, with in-cloud temperatures pegged solidly in the favorable dendritic growth layer and an uptick in inversion levels with primary shortwave passage. Several inches of snow possible, especially in the more favored lake enhanced areas west of Interstate-75. Possible headlines in those favored flow regimes mentioned above.

Lake effect snow develops Saturday night as winds gradually veer from west to northwest. Parameters looks fairly good for a time with plenty of moisture through the DGZ before the atmosphere becomes more hostile to lake effect snow toward Sunday morning with lowering inversion heights and progressively drier air. Additional with high The main forcing/moisture with this feature will dive south of our area. Very dry and extremely cold air works into northern Michigan presenting a fairly hostile atmosphere for lake effect. Likely still some lake effect on Sunday, but low inversion heights and moisture outside of the favored DGZ will result in only minor accumulations.

LONG TERM. (Sunday night through Thursday) Issued at 202 PM EST Thu Jan 20 2022

High Impact Weather Potential: Additional accumulating snow

Northwest flow regime continues through this period. Pattern strongly favors additional clipper type systems, bringing additional lake enhanced snow potential. One such system will slide into the Great Lakes later Monday into Monday night. Too early to get specifics on amounts or magnitude, but accumulating snow appears likely across much of the area in this timeframe. Lake effect will continue in the wake of this system, resulting in additional snow accumulations in the favored snowbelts. Another moisture starved clipper could approach the area by later Thursday. An active pattern with several snow chances throughout. Temperatures expected to run below normal, especially for daytime highs, with readings mostly in the teens.

AVIATION. (For the 18Z TAFS through 18Z Friday afternoon) Issued at 1242 PM EST Thu Jan 20 2022

Light lake effect snow showers and flurries at times near the Lake Michigan shoreline through the period. The flow will be rather light with high pressure off to our west. Winds will shift from light northwest today to southwest on Friday. Cigs will straddle the MVFR/VFR threshold through the period but trend toward low end VFR with time.

MARINE. Issued at 202 PM EST Thu Jan 20 2022

Light and variable winds through tonight will become southwest and become a bit gusty Friday. Stronger winds are then expected Friday night and especially Saturday with a few gale force gusts possible.
