LATEST UPDATE...
Discussion/Marine

.DISCUSSION...(Today through next Sunday)
Issued at 328 AM EST Mon Nov 22 2021

- Quiet Weather Returns Today Through Wednesday -

Upper level ridging will move into the region starting today leading
to quiet and dry weather through the start of the work week. Surface
flow will turn southerly by Tuesday afternoon leading to a warming
trend through Wednesday. Early morning wind chills will be in the
teens today with high temperatures warming into the 30s this
afternoon, 40s for Tuesday, and up to near 50 by Wednesday. In
addition to warming temps, our lake effect snow and cloud cover
should diminish as delta T's drop thanks to warm advection.

- More Active Weather Around Thanksgiving -

Our next system of note looks to approach the area around Wednesday
night then moves through the Great Lakes on Thanksgiving Day. Our
prolonged southerly flow will keep precipitation of the liquid
variety Wednesday evening before we see a transition over to snow
later in the day on Thursday as flow turns northwesterly. Some light
snow/slush accumulations will be possible, mainly in the afternoon
and evening after the precip transition occurs and temperatures
drop. Accumulations are not expected to be substantial, but some
travel impacts should be considered given the holiday. Light lake
effect snow is then expected to last Thursday night into Friday.

Winds will also turn gusty as this system approaches and the
pressure gradient between a high over the eastern seaboard is
pressed by the surface trough to our west. Ensembles suggest gusty
winds will ramp up Wednesday afternoon with gusts up to 40 MPH
possible into Thursday evening. The highest gusts will be along the
lakeshore.

- End of the Week Outlook -

Model disparity increases as we head into the end of the week, but
there seems to be consensus on an upper trough moving through the
region. Lake effect precipitation looks possible this weekend, with
overall details still muddled in model disagreement.

&&

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1230 AM EST Mon Nov 22 2021

Gusty winds continue following the passage of the cold front
earlier this evening but winds will gradually subside through
early this morning. Meanwhile mainly VFR should persist through
the forecast period, however some MVFR cigs will be possible
mainly near the lakeshore as lake effect clouds stream in. Winds
should be weaker this afternoon, but gusts to 20 knots are
expected.

&&

.MARINE...
Issued at 328 AM EST Mon Nov 22 2021

Gales are continuing along our lakeshore, but winds are expected to
diminish through this morning. With hazardous winds and waves still
expected to last today into Tuesday, a Small Craft Advisory will
follow once the Gale Warning expires.

Soon after this event ends, gusty southerly flow will return Tuesday
night into Wednesday with winds likely reaching gale force. Winds
will shift northwesterly Thursday morning with small craft advisory
conditions lasting through the rest of the week.

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...None.
LM...Small Craft Advisory until 4 AM EST Tuesday for LMZ844>849.

     Gale Warning until 5 AM EST early this morning for LMZ844>849.
