Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
646 PM EST Sat Dec 24 2016

.AVIATION...

Extensive canopy of MVFR stratus to remain locked in throughout SE
Michigan this TAF period.  Adequate moisture depth tucked beneath a
stout subsidence inversion will ensure this condition varies little
over the next 24 hours.  This cloud cover will dampen the potential
for fog tonight, despite a diminishing wind field and moist/snow
covered near surface environment.  Some shallow fog remains
plausible carrying MVFR restrictions through the morning hours.
Winds will increase out of the easterly direction on Sunday.  Weak
cold air advection in this flow may provide a slight boost to
ceiling heights during the day.

//DTW Threshold Probabilities...

* High for cigs aob 5kft through the TAF period.

.PREV DISCUSSION...
Issued at 324 PM EST Sat Dec 24 2016

DISCUSSION...

The exit of last nights weak system leaves SE MI in the midst of a
quiet period before a developing winter storm lifts through the
Midwest and Ontario Sunday night through Monday night. The storm
track will result in warm conditions across MI with mainly rain
although there is still a chance of some freezing drizzle on the
lead edge of the moisture.

For the rest of today and tonight, ridging aloft and at the surface
will take over across the region. The weak shortwave exiting has
opened the door for the upper level ridge to slide east over the
area. Meanwhile, a strong jetlet shooting through the already deep
west coast trough will cause rapid intensification of the trough and
developing surface reflection over the central/southern Rockies.
Downstream ridge amplification will result in deep southerly flow
ahead of the trough bringing warmer and much moister air all the way
to the Great Lakes by Monday. The system will be very dynamic with a
closed upper low, sub 990mb surface low, +120kt jet, mid level
diffluence, and fgen across the region. Expect isentropic ascent
ahead of the low with strong southerly flow to ignite light
precipitation across southern MI Sunday evening into the overnight.
Main question with this system will be ptype on the lead edge Sunday
night. Strong subsidence from the 1045mb high passing north through
Ontario will produce a stout inversion down around 925mb leading
into the system. Easterly flow out of Canada will keep temps down at
or just below freezing Sunday night after only maxing out in the mid
30s Sunday. Evaporational cooling due to the extensive layer of dry
air will likely drop temps a couple degrees at the onset as well
before deeper moisture and higher precip rates prevent wet bulbing.
Moral of the story, as moisture begins moving in around 03-06Z
Monday, many locations will see light freezing drizzle or drizzle.
Chances of snow are extremely low as moisture depth is too shallow
to get ice crystals to form. This will change over to all
drizzle/rain as warmer air arrive and rates increase. Lack of QPF
during the onset will keep any icing accumulations minimized with
guidance suggesting less than 0.1".

Surface warm front will lift north through southern MI Monday
morning bringing much warmer temperatures to the region where most
locations will see 50 degrees. Those closer to the Ohio border
should get into the mid 50s. Warm air will hold through the day
until the low (crossing into Quebec Monday evening) pulls an
occluding cold front through SE MI around 00Z Tuesday. Dry air in
its wake will quickly bring an end to any remaining rain showers.
Temperatures will also see an abrupt change as 850mb temps drop from
+10C Monday morning to -10C by Tuesday morning so after one day in
the 50s, we'll quickly return to having highs in the 30s.

By Tuesday, surface high pressure to the south along with upper
level zonal flow will keep conditions quiet through late Wednesday.
The upper level flow pattern then changes as longwave troughing with
embedded shortwaves drop down into the Great Lakes region.  This
will slowly bring in slightly cooler air through the remainder of
the week to round out this year.  Chances for precipitation will come
back into play as a result of the multiple shortwaves that work
across the area on Thursday and again in the start of the New Year.

MARINE...

High pressure will expand across the region tonight, supporting
weakening winds. On Sunday, strong high pressure will expand into
Quebec, while rapidly deepening low pressure lifts into the Dakotas.
This will result in a strengthening easterly flow across the lakes
during the course of the day. There will be enough shallow cold air
across Lake Huron to support a period of unstable conditions,
resulting in wind gusts to gales Sun night across the northern half
of the lake. Gale force gusts will then spread across the remainder
of the lake Monday morning. The passage of the associated occluded
front Monday afternoon will result in a temporary weakening of the
winds. Post frontal cold air advection with the deep sfc low passing
north of Lake Superior will then result in west-southwesterly gales
late Mon afternoon through Monday night. A gale watch will remain in
effect through this period. Confidence on gale force gusts are quite
high, so the watch is expected to be upgraded to a warning either
this evening or early Sun morning.

HYDROLOGY...

An influx of warm moist air will be transported into Southeast
Michigan Sun night, resulting in widespread rain. This will occur
within the warm sector of the strong low set to lift across the
Dakotas on Sunday. The rain will persist into Monday afternoon
before ending. Total rainfall from this system is expected to range
between a quarter inch and half inch. In addition to the rain,
temperatures will rise well above freezing by Monday morning. The
warm temps combined with the rain will result in rapid snowmelt.
This will result in short term rises in area rivers, but not enough
to lead to flooding concerns.
