Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
350 AM EDT Sat May 6 2017

.DISCUSSION...

Gusty wind and cool temperatures will continue today with a chance
of showers inland while a steadier light rain brushes the Thumb
region. This is still a more optimistic rain forecast as the latest
model runs have held the trend toward a progressive solution on the
upper level through over the eastern Great Lakes. Expect to see most
locations break into the 50s for highs today outside of the Thumb but
wind gusts reaching 30 mph at times will keep it from feeling that
way. Dry and colder air surging southward from central Canada will
then promote a clearing trend and bring temperatures down into the
mid and upper 30s for lows tonight. Wind is expected to inhibit frost
development tonight but which will be followed by an additional
cooling trend Sunday night/Monday morning when widespread freezing
temperatures will be possible.

The catalyst for the next stage of upper air development will be the
short wave moving rapidly from the Midwest into the base of the
trough over the Tennessee valley by afternoon. This will cause some
deformation rain over Ontario during the morning to bend farther
west into the Thumb during the afternoon while remaining light.
There is good model agreement on QPF ranging from a few 100ths to
possibly 0.1 by evening. Farther inland, enough moisture is
indicated within the low level thermal trough for a broken coverage
of cumulus to develop with daytime surface heating. Chance POPs are
extended westward and southward from the Thumb to account for some
instability showers that will be possible as well, on the western
fringe of the system cloud shield. Forecast soundings across model
runs all indicate steep lapse rates below 700 mb with boundary layer
moisture adequate for positive area up to about 650 mb. From there a
weak subsidence induced warm layer is shown to limit additional
development. Scattered coverage of high based showers will then have
a strong diurnal dependence and diminish around sunset.

Deepening of the large scale low pressure system today will increase
the northerly gradient flow and cold advection over the northern
Great Lakes which will spread southward tonight. The incoming air
mass is impressively cold and dry in model depictions that show
strong low level thickness cooling and 850 mb temps near -5C as far
south as the Saginaw valley by sunrise Sunday. Moderate northwest
wind will continue through the day to maintain cold advection strong
enough to withstand early May surface heating resulting in highs
only in the lower to mid 50s despite full sunshine. This will set
the stage for freezing temps Sunday night into Monday morning as the
sky remains mostly clear and lighter wind allows some additional
radiational cooling.

The cold air in place during the weekend will be nudged eastward
during the first half of next week. The mature blocking pattern in
the upper levels will allow weak surface high pressure to settle
over the Great Lakes and bring a slow warming trend to the region.
Daytime temps lingering in the lower to mid 50s Monday are shown to
reach around 60 by Wednesday.

.MARINE...

Prolonged northwest flow over the Great Lakes Region this weekend.
Cold airmass looks to support enough mixing to reach gales over much
of the open waters of Lake Huron Tonight into Sunday, and a gale
warning has been issued. Small craft advisories remain in effect
through Sunday for nearshore waters. Lighter winds, below 20 knots,
returns early next week as high pressure arrives. Light winds and
favorable boating conditions then look to persist through the end of
the work week as well.

AVIATION...

VFR conditions are expected overnight now that west edge of stratus
associated with low pressure has shifted east. This system remains
nearby on Saturday within blocked upper level pattern, so there will
be plenty of low level moisture to allow for the formation of a bkn
strato-cu/cu deck from diurnal heating. Decent mixing along with a
modest pressure gradient will bring NNW wind gusts to near 25 knots.

For DTW...VFR conditions overnight with 4-5kft sct-bkn deck expected
on Saturday. Winds will gust to near 25 knots at times by midday.

//DTW THRESHOLD PROBABILITIES...

* Medium cigs aob 5kft on Saturday.
