Update
Issued at 1044 am est Thu dec 13 2018
morning composite analysis reveals a broad ridge trough ridge
pattern across the conus. Main upper jet takes a deep dive from
the rockies into south-central CONUS with a detaching mid level
short-wave and low pressure closing off over texas. Weaker
northern branch and short-wave trough is progressing through the
northern plains. At the surface, high pressure remains stretched
along the eastern conus. Low pressure is over texas ahead of the
aforementioned short-wave with a surface trough that stretches
northward through the plains. Most of the active weather is down
south in texas and the lower mississippi river valley, although
there is some lighter precip moving through minnesota.

Here at home, abundant stratus and fog encompasses much of the
western great lakes. There is a thin sliver of dry air clear skies
cutting across the SW part of the CWA and down into the saginaw
valley and some thin spots across NE lower michigan.

Cloud cover fog is obviously the main forecast problem for today.

Fog will slowly improve as we "warm". And as mentioned, there is
a thin sliver of clearing that is sort of migrating slowly
northward through northern lower michigan and some other thin
spots that will bring some sunshine to some locations over the
next several hours. But there is also another "wing" of stratus
sliding up through western lower michigan that will try to fill in
behind. So... All told most areas will probably end up on the
mostly cloudy side of things.

Otherwise, quiet weather conditions anticipated trough the day
overall.

Near term (today through tonight)
issued at 247 am est Thu dec 13 2018

Low clouds with periodic light precip chances thru tonight...

high impact weather potential... Patchy light freezing drizzle may
cause some slick spots on roads this morning and again overnight.

Pattern synopsis forecast... Slow-moving low pressure remains
centered just west of lower michigan early this morning... With a
weak stationary front extending southward into the ohio valley and
mid mississippi valley. Last evening's light snow has exited
eastward out of lower michigan... But plenty of low clouds along with
areas of fog and flurries light freezing drizzle remain across our
cwa. Latest satellite loop does show some periodic holes in the low
cloud shield... But most of these are relatively short-lived and are
tending to fill back in. Temps have dropped into the 20s in a few
locations that have seen some temporary clearing... But temps across
most of our CWA remain in the lower 30s early this morning.

For today... Low pressure will continue to push eastward thru se
ontario today... With surface and upper level ridging building into
michigan in its wake. Shallow low level moisture clouds will hold
over the region... Maintaining an overall mainly cloudy skies today
and tonight. Low level SE flow will maintain upslope flow across
eastern sections of our cwa... Which will maintain the chance of some
patchy light freezing drizzle across these areas thru this morning.

Areas of fog will also hold over the region this morning before
limited daytime heating lift the fog and may punch a few more holes
in the low clouds as well. Chance of freezing drizzle will end by
afternoon as low level temps warm and surface temps rise into the
mid 30s.

For tonight... The tail end of a weak front will clip eastern upper
michigan... Providing small chances of some light snow light freezing
drizzle during the evening. Better chances of light snow light
freezing drizzle will develop overnight as an inverted trough pokes
into michigan. As is typical lately... Limited moisture and weak lift
will result in light precip intensity and thus relatively minor snow
accumulations (under an inch for our entire CWA overnight). Low
temps overnight will cool into the upper 20s to around 30 degrees.

Short term (Friday through Saturday)
issued at 247 am est Thu dec 13 2018
high impact weather potential: freezing drizzle possible Friday
morning.

Primary forecast concerns challenges: timing of precip.

Mid level moisture continues to strip out behind departing frontal
boundary although low level moisture exits a few hours later. This
low level moisture will produce chances for some light snow and
freezing drizzle for the first few hours of Friday
morning... Possibly making for a slippery morning commute. High
pressure and much drier air then builds into the great lakes region
and will provide precipitation free weather Friday afternoon through
Saturday. High temperatures will be in the mid 30s to near 40
degrees.

Long term (Saturday night through Wednesday)
issued at 247 am est Thu dec 13 2018
high pressure and dry air continue to dominate northern michigan's
weather through the end of the weekend. The next chance of
precipitation appears to be Sunday night into Monday with some lake
effect enhanced snow possible behind a departing cold front
associated with a low pressure system over hudson bay with
northwesterly winds filtering in colder air. High pressure and dry
air once again build into the forecast area behind this frontal
boundary. Daytime temperatures will remain mild Sunday, before
dropping back to near 30 degrees behind aforementioned cold front
Monday.

Aviation (for the 18z tafs through 18z Friday afternoon)
issued at 1259 pm est Thu dec 13 2018
once again, lots of MVFR cloud cover across the region. There are
some thin spots clearing that may bring some temporaryVFR weather
to the terminal sites. But overall, anticipate MVFR conditions
through the afternoon.

Tonight, surface trough across the midwest today will cross
through the region later overnight into Friday. Increasing
southerly winds ahead of this system may actually help scour out
the lower cloud cover for a time, replaced by thickening mid and
high level cloud cover. Some light precip slides through the
region with this system, mainly in the form of very light snow,
although a little -fzdz is also possible.

Marine
Issued at 247 am est Thu dec 13 2018
winds and waves will remain below SCA criteria thru the end of the
work week. Low clouds... Patchy fog and periodic chances of light
snow light freezing drizzle will continue for our nearshore areas
thru Friday.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
