Area Forecast Discussion
National Weather Service Gaylord MI
330 AM EST Sat Mar 4 2017

.NEAR TERM...(Today)
Issued at 330 AM EST Sat Mar 4 2017

...Sunnier and not quite as cold...

High impact weather potential...none.

High pressure is crossing the region early this morning. Wnw-flow
lake effect snow is finally falling apart in both peninsulas.
Between now and 15z (10am), 1000-850mb flow disappears, and that
will fully take care of that. Outside of lake effect regimes,
skies were clear and temps were getting rather cold, especially at
the usual cold spots (PLN/Grayling). This forecast generally
looks pretty quiet in the near term.

Today/tonight...surface high will only slowly move east, with the
center reaching ne of Georgian Bay by evening, and only drifting east
of there tonight. Low level flow in the wake of the high will be s
to sse, which should any pesky land-breezed-forced shsn over Lake MI
from having any real impact in this forecast area. Cloud cover will
be something of a challenge. Lake MI is producing less in the way
of lake clouds, but old cloud cover has drifted over to APN and
surrounding areas, and has stalled. BUFR soundings show this cloud
deck may be difficult to dislodge, especially with a slight
onshore component to the low-level flow by late morning. Some of
this will eventually be shunted back into eastern upper MI as
well. Otherwise, some cirrus will try to work in from the sw
today. Tonight, any lingering low clouds should get shove north
out of northern lower. However, eastern upper soundings look
somewhat stratus-y, with a lot of moisture trapped below 925mb.
Will have cloudier conditions tonight north of the bridge vs
south. Almost toward dawn, mid clouds will expand into northern
lower MI as mid- level theta-e advection sees a brief spike.

Max temps today range from near 20f in the St Marys Valley to the
lower 30s near MBL and Frankfort. Min temps tonight from 10f at the
Sault to mid 20s MBL/Frankfort.

&&

.SHORT TERM...(Tonight through Monday)
Issued at 330 AM EST Sat Mar 4 2017

...Warmer with increasing chances for rain...

High Impact Weather Potential...Minimal. Small chance of light
freezing rain across mainly eastern Upper on Sunday.

Pattern Synopsis/Forecast...With a tight pressure gradient in place
across the region on Sunday, gusty southerly winds will lead to
intensifying WAA across the Upper Great Lakes. Moisture will
initially be largely unimpressive, generally confined to the lowest
10,000 feet or so through the day thanks to mid-level subsidence
from upper ridge overhead. This will limit overall chances of
precipitation during the day, despite ongoing respectable isentropic
lift and WAA (especially near and north of the Straits). In fact,
with the latest 00Z run, models are trending drier for much of the
day, and will therefore go with slight chance. As Gulf flow
eventually opens up Sunday night into Monday, moisture advection
will markedly increase with PWATs approaching 1 inch (3 to 4
standard deviations above the mean for early March) in northern
Michigan by Monday evening. With this deeper moisture coming into
play and the upper ridging eventually pushing east, expect cloud
cover and rain chances to steadily increase Sunday night into Monday
in ongoing WAA and isentropic ascent regime.

Temperatures will continue their warming trend to start the week
with highs on Sunday ranging from low to mid 30s north to low 40s
south and lows Sunday night at or above freezing in most locations.
Steady WAA continuing into Monday will push highs to around 50
degrees across northern Lower and mid 40s across eastern Upper.

Primary Forecast Concerns...Ptype Sunday morning, especially near
and north of the Straits, still remains a bit of a concern with
surface temperatures initially below freezing and a warm nose
developing just off the surface. In-cloud ice nucleation will be
marginal at best, so thinking freezing rain will be the favored
ptype with some snow/sleet perhaps mixing in here and there. But it
should be reiterated that precip chances overall look quite low
during the day and therefore not expecting much impact due to any
wintry precipitation. Surface temperatures across far eastern Upper
now looking to remain at or just below freezing for a bit longer
than earlier expected, so the chance for freezing rain may linger
there into Sunday night. But the rest of the area will transition to
rain as temperatures rise.

As dewpoints climb above freezing Sunday night and into the 40s on
Monday, we'll start to get into very efficient melting of the
snowpack across northern Michigan. Combined with a warm, moist air
trajectory, will have to monitor for the potential of advection fog.
Have put some patchy fog in the grids Sunday night into Monday AM.

.LONG TERM...(Monday night through Friday)
Issued at 330 AM EST Sat Mar 4 2017

High Impact Weather Potential...Looking minimal at this time, but we
will return to snow for the second half of the week with some
accumulation likely.

Out ahead of a strong approaching cold front Monday night, northern
Michigan will be situated right on the nose of some pretty strong
moisture transport for this time of year thanks to a robust ~60 knot
LLJ. Instability will be meager as the front rolls through early
Tuesday, however, with only around 100 J/kg or less of MUCAPE. Good
thing, too, as 0-6km bulk shear will be healthy along the front
Tuesday morning around 60+ knots. Wouldn't completely rule out some
isolated thunder, but it's not looking too likely on this side of
Lake Michigan and have left out of the forecast at this time. There
are some fropa timing differences between the deterministic models
with the GFS the fastest (clearing our east well before daybreak)
and the ECMWF slowest (just entering our CWA around daybreak). The
NAM/CMC lie somewhere in between. Interestingly, despite the
expected favorable moisture transport, model QPF signatures are
trending less impressive. Will continue to monitor this system
closely, but it looks like bulk of the precip clears out pretty
rapidly behind the front. It will turn a bit windy along and behind
the front on Tuesday, continuing into Wednesday before the pressure
gradient relaxes.

Some showers may develop in the strong CAA Tuesday afternoon,
especially as wrap-around moisture works its way into northern
Michigan. Some lake enhancement may also come into play on Wednesday
as 850mb temperatures drop to around -15C, but high pressure will
bring drier weather as it drops out of Canada and slides across the
Upper Midwest Wednesday night into Thursday. Pretty good signal for
a clipper system to plow through northern Michigan Thursday night
into Friday, and from the looks of current model QPF, it could bring
some healthy snow amounts to the area. Temperatures for the second
half of the week will be cooler, but right around seasonal
normals.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1129 PM EST Fri Mar 3 2017

VFR conditions with just some flurries floating between TVC/PLN
through shortly past midnight. Then, incoming center of sfc high
pressure results in light winds along with a lowering inversion
with drying from aloft. This is expected to definitely result in
a continuation of clear skies and land breezes with very cold
temperatures by daybreak. Less confidence in any sort of brief
MVFR CIG after sunrise. Skies now expected to be sunny with just
some thin incoming higher level clouds.

LLWS expected to develop late evening Saturday under strengthening
warm advection.

.MARINE...
Issued at 330 AM EST Sat Mar 4 2017

winds will increase again behind the high, especially tonight into
Sunday. Advisory will likely be needed again, some of which will
be issued later this morning.
