This hazardous weather outlook is for portions of southwest Lower
Michigan.

.DAY ONE...Today and Tonight

Lake effect snow showers will create hazardous travel conditions
with slick roads at times today and tonight particularly near to
west of a line from Muskegon to Battle Creek.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Lake effect snow showers will create challenging travel conditions
with slick roads at times through the upcoming week. Snow could
become heavy at times near the Lake Michigan shoreline Monday
through Monday night.


Weather History

2006: A snow and ice storm strikes southwest Lower Michigan. From 6 to 12 inches of snow falls from Muskegon to Ludington, while an ice storm causes power outages and treacherous travel conditions from Kalamazoo to Lansing.

On December 1, 1974, 19.3 inches of snow fell in Detroit, the second-highest snowfall ever recorded in the city.


Forecast Discussion

- Lake effect snow showers today and tonight

WNW flow lake effect snow showers will continue to develop today
as a result of favorable delta t/s and increasing low level moisture
in conjunction with a bump up of inversion heights to around 8 to
10 kft agl which are also favorable. This in conjunction with
some omegas through the dgz will result in light to moderate snow
showers with potential for accumulations of around one to four inches
near to mainly southwest of a line from KMKG to KBTL.

This notion is supported by most higher res guidance and the
00Z HREF 12hr snowfall PMM product. Therefore we issued a winter
wx adv headline for Barry Kalamazoo and Calhoun counties from
early this morning through this afternoon as snow showers are
already occurring across this area attm and will continue through
the day leading to hazardous travel conditions.

In addition for this afternoon we expect lake effect snow showers
with a Lake Superior connection to impact our far northern
counties as low level wind fields veer more to the nw. So we have
also hoisted a winter wx adv headline for Lake Osceola and Clare
counties for this aftn through tonight.

- Heavy lake effect snow across our lakeshore counties Monday

An overall consensus blend of latest 00Z guidance shows potential
for heavy lake effect snow to impact our lakeshore counties
Monday as robust omegas through the dgz develop with deep
moisture in place and favorable delta t/s. A sfc trof moving in
from the nnw will also be a focusing mechanism for heavier snow to
develop. Latest 00Z HREF guidance shows potential for at least 6
to 8 inches of snow across portions of our lakeshore counties with
locally higher amounts probable.

We expect narrower but intense snow bands to develop given weak
low level winds with sfc winds gradually attaining more of a NNW
flow component and becoming more unidirectional with height Monday
afternoon after passage of the sfc trof from the nnw. Given the
strength of omegas through the dgz snowfall rates will reach an
inch per hour at times. 00Z HREF probabilistic guidance even shows
potential for two inch/hr type snowfall rates from mid morning
through mid to perhaps late afternoon and this notion seems quite
plausible.

A few locations near the Lake MI shoreline have potential to end
up with snowfall totals of around ten inches to close to a foot.
Given all this we have decided to hoist a winter storm watch for
our lakeshore counties from early Monday morning through Monday
night. Thx for extensive collab/coord on the fcst and headline
decisions APX/IWX/WPC.

- Risk for snow continues through much of next week

For Sunday night into Monday night, a 700 mb wave drops in from the
northwest. Low level convergence increases and the moisture depth
lifts into the 700 mb level where temps will be around -20 deg C.
Thus we are likely to see an increase in the  snow showers then,
especially near and west of US-131.  It`s possible that we will need
winter weather headlines for the passage of this system. The latest
High Res Euro shifts the main snow bands offshore Monday night which
does tend to happen when the winds swing around to the north.  Not
all models are in agreement that the winds will swing completely
around to the north then.

Then for Tuesday night into Wednesday, a longer fetch sets up as a
southwest flow develops ahead of an approaching potent mid level
wave.  Moisture from Lake MI will feed into this system as it tracks
through.  The strongest low level convergence will be over northwest
parts of the CWA.  That`s also the region closest to the passing mid
level support.  Fairly high confidence for a widespread accumulating
snow event exists with all models supporting this setup.  Ensemble
snowfall amounts have been trending up with this system as well.

Beyond Wednesday, another surge of arctic air settles in behind the
departing wave.  Temps at 850 mb are shown to fall down into the -15
to -20 deg C range.  This will generate plenty of instability to
keep the lake effect snow showers going and accumulating.  The
northwest flow favors western parts of Lower MI for the most
accumulations.
