Near term (today through tonight)
issued at 231 am edt Mon oct 15 2018

Cold and rainy today with a mix of snow in some locations...

high impact weather potential... None.

Pattern synopsis forecast... A cold front is making its way thru our
cwa early this morning. Showers are increasing in areal coverage
over our CWA as a wave rides along the front thru lower michigan.

Rain showers are mixing with and in some locations have changed to
snow showers across eastern upper michigan where temps have cooled
into the low to mid 30s. Precip remains all liquid across northern
lower michigan where temps remain in the 40s.

Widespread precip will continue to develop early this morning across
our entire CWA as that wave slides thru the region along the cold
front. Cold FROPA this morning will lead to diminishing pops from
west to east in the wake of the front... Beginning around mid morning
and continuing into the afternoon hours. Synoptic event will
transition into a lake enhanced event later this afternoon and early
evening as low level CAA commences. Also... W NW winds will
strengthen in the wake of the cold front today... Gusting to 30 kts
at times. All remaining precip will come to an end later this
evening and overnight as high pressure and drier low level air build
into michigan.

Temps will be noticeably colder today... With high temps ranging from
the upper 30s and lower 40s across the NW two-thirds of our CWA and
in the mid 40s near saginaw bay. Low temps tonight will drop mainly
in the lower 30s... With slightly warmer temps downwind of lake
michigan.

Short term (Tuesday through Thursday)
issued at 231 am edt Mon oct 15 2018
high impact weather potential: minimal aside from a few low end gale
force gusts on lake michigan and huron early Tuesday.

Pattern synopsis: brief surface and upper-level ridging are expected
to be evident Monday night before a well-defined shortwave aloft and
attendant area of surface low pressure pass to our north, dragging a
cold front across northern michigan Tuesday morning. This will set
the stage for another shot of colder air Tuesday afternoon through
Wednesday with lake effect rain snow showers expected. By late
Wednesday Wednesday night rising heights aloft are expected to be
the rule with shortwave ridge axis crossing overhead during the day
Thursday. Combined with strong surface high pressure anchored to our
south should provide plenty of influence to taper any lingering lake
induced precipitation by Wednesday evening.

Primary forecast concerns challenges: lake effect shower chances
Tuesday through Wednesday.

By the start of the forecast period Tuesday morning, a cold front is
expected to be crossing northwest to southeast across the forecast
area... Tied to the aforementioned area of low pressure trekking
south of hudson bay. Will continue to carry mainly chance pops
across far northern areas with the frontal passage itself before
much colder air aloft pours into northern michigan Tuesday afternoon-
Tuesday night... Setting the stage for increasing lake induced shower
chances. Most widespread lake effect shower coverage expected to be
in west-northwest flow favored lake belts Tuesday night into early
Wednesday morning as h8 temps fall to -6 to -9 c (delta TS over 20
c) and inversion heights climb to 7.5-8 kft... In addition to
increased synoptic support and pockets of deeper moisture as the
trough axis rotates overhead. Wouldn't be surprised if most of this
activity falls in the form of wet snow Tuesday night into early
Wednesday morning, primarily across upper and interior northern
lower given decreasing freezing levels... Progged to steadily fall
below 1,000-1,200 ft. By 04-06z. This perhaps leading to a minor
accumulation (generally an inch or less) in any steadier more
persistent snow showers able to gain connection from lake superior
and lake nipigon in south-central ontario.

Precip chances slowly wane throughout the day Wednesday given
decreasing deep layer moisture (but will likely continue in isolated
to scattered fashion longer than guidance suggests as so often
happens given slow-to-retreat cold air aloft). Will extend low-end
pops into Wednesday night across wnw flow lake belts before waa
really takes over by early Thursday morning. Quiet weather
anticipated through the remainder of the forecast period on Thursday
as low-level winds back more southwesterly aiding to boost high
temperatures into the low 50s for most (some 10-15 degrees warmer
than the mid-upper 30 degree highs expected on Wednesday).

Pressure gradient over northern michigan will remain a bit robust at
times through Wednesday given system after system marching through
the region, which will lead to gusty daytime conditions. Will have
to monitor potential for a few low end gale force gusts towards
saginaw bay and over northern lake michigan early Tuesday. If these
were to materialize, they'd occur over a rather brief period of time
and would be pretty isolated.

Long term (Thursday night through Sunday)
issued at 231 am edt Mon oct 15 2018
another well-defined trough and associated area of surface low
pressure dive south out of canada late in the week, dragging a cold
front through northern michigan. This will aid to usher in yet
another shot of cold air aloft leading to more lake effect rain snow
showers by Friday night, continuing at times through the upcoming
weekend.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 645 am edt Mon oct 15 2018
colder air will advect into northern michigan today and tonight in
the wake of a cold front moving thru our region early this
morning. Widespread synoptic rain will transition to lake enhanced
rain showers today and early evening. Remaining ifr CIGS will lift
to MVFR as this occurs. All shower activity will end later this
evening and overnight as high pressure and drier air build into
the region... WithVFR conditions returning to the region. W nw
winds of 15 to 25 kts will occasionally gust to 30 kts today into
this evening... And will then shift to the SW and diminish to
around 10 kts late this evening and overnight.

Marine
Issued at 231 am edt Mon oct 15 2018
winds and waves will reach gale warning criteria within most of our
lake huron nearshore areas today and tonight... And SCA criteria
within the rest of our nearshore areas as W NW winds strengthen in
the wake of a cold front. Widespread showers (mainly rain with a mix
of snow for some locations) will gradually diminish once the cold
front passes... And will transition to lake enhanced showers later
today into this evening before ending later tonight as high pressure
builds into the region.
