Area Forecast Discussion
National Weather Service Gaylord MI
317 PM EDT Thu Sep 28 2017

.NEAR TERM...(Tonight through Friday)
Issued at 317 PM EDT Thu Sep 28 2017

...Increasing chances of precip and cooling temps...

High Impact Weather Potential...Slight chance of thunder tonight and
Friday.

Pattern Synopsis/Forecast...Surface ridging extends from SE Ontario
thru Lower Michigan into the Mid Mississippi Valley and the Central
Plains late this afternoon. Area of low pressure continues to
develop over the heart of Ontario...generating some clouds and
showers from Central Ontario into Northern Minnesota. Much of our
CWA remains dry for the moment with high pressure maintaining
control...although clouds are steadily increasing from NW to SE as
the upstream cold front begins to approach.

Central Ontario low will drop SE into Upper Michigan and SE
Ontario...with the associated cold front sweeping thru our CWA.
Cloud cover will continue to increase from NW to SE this
evening...with chances of showers increasing as well along and ahead
of the front. MUCAPES increase to 500 to 750 J/kg as colder air
aloft pushes into the region tonight and Friday...so still cannot
rule out an isold thunderstorm...mainly across Northern Lower
Michigan. Low level CAA behind the front will also serve to
sufficiently increase over-lake instability to provide enhancement
to ongoing precip production for our typical N/NW flow areas.
Suspect lake effect/enhanced precip will linger into Friday
afternoon for NW Lower Michigan as winds shift to a more northerly
component and cold temps remain in place with lingering low level
moisture.

Temps will drop into the 40s for overnight lows tonight...with
warmer temps by the lakeshores. Cooler temps are expected for Friday
thanks to ongoing CAA. Afternoon highs will range from the upper 50s
to around 60s for most of our CWA to the low to mid 60s near Saginaw
Bay where the cold front will pass thru last.

&&

.SHORT TERM...(Friday night through Sunday)
Issued at 317 PM EDT Thu Sep 28 2017

...Cool nights upcoming...

High Impact Weather Potential...Frost Friday night and Saturday
night. The most coverage is expected on Friday night.

Pattern Synopsis/Forecast...The 500 mb low over the Upper Great
Lakes continues to move east into New England, and the heights begin
to build. As the heights build, the 700-500 mb layer RH dries out.
This should end the precipitation in the east, at least from a
synoptic perspective. From a mesoscale perspective, however, looking
at the synoptic moisture in the 850-700 mb layer is around 40% so
enough to continue the clouds and with the delta Ts around 16c, and
a north flow, will expect that lake effect rain will continue into
the early part of the evening (00z-03z), but will expect that with
more drying through the evening that by midnight we should see all
the showers come to an end, and the cloud cover breaking. The sfc
high rolls into the Upper Great Lakes and is pretty much centered
over N Michigan by 12z/Sat. Will expect that the winds will drop to
calm, and with the clear skies we will radiate enough for
temperatures to possibly form frost or fog. Will expect sunshine as
Saturday as the high remains over the region. Temperatures will warm
a bit as the sunshine takes over. however, will expect another
chance for frost by Sunday morning, but it's not expected to be as
widespread.

Primary Forecast concerns...Main concern is the frost or fog
formation. As has happened before, setup looks right for both. Frost
was in the grids, and left them. The rapid drying may be able to
allow the frost to form instead of the fog. However, looking at this
from a UPS fog tool perspective, the cross over temperatures are
expected to be almost 10 degrees F warmer than the lows. So the risk
is that the fog could upset the frost potential.

&&

.LONG TERM...(Sunday night through Thursday)
Issued at 317 PM EDT Thu Sep 28 2017

Temperatures are expected to remain above normal as ridging remains
over the eastern CONUS through most of the week. Could see some
isentropic ascent driven showers as early as mid week as height
falls begin working in from the west. Better chance for showers will
be later in the week as a cold front moves through.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 103 PM EDT Thu Sep 28 2017

Chances of showers will increase tonight in response to the
arrival of low pressure and an associated cold front. Colder air
sweeping into Michigan in the wake of the front will increase
over-lake instability to provide lake enhancement to ongoing
synoptic precip later tonight into Friday. A thunderstorm is not
out of the question as well. Overall conditions will remain VFR
despite increasing chances of showers. Conditions may drop to MVFR
within any heavier showers/storms that develop. Westerly winds
around 10 kts this afternoon/evening will shift to the N/NW in
Friday and strengthen to 15 to 25 kts with some higher gusts
possible.

&&

.MARINE...
Issued at 317 PM EDT Thu Sep 28 2017

Winds and waves will increase to SCA criteria for much of our
nearshore areas late tonight and Friday as a cold front sweeps thru
the region. Chances of showers will increase...with a slight chance
of thunderstorms. Precip will become lake enhanced as cold air moves
into the region in the wake of the cold front...targeting mainly our
Lake Michigan nearshore areas of highest chances of precip.
