Synopsis
Issued at 258 pm est Fri nov 16 2018
a cold front will bring some light snow late tonight into
Saturday morning. Then fair and cold weather is expected into
Monday morning, when a clipper could bring some more light snow.

Discussion (this evening through next Friday)
issued at 258 pm est Fri nov 16 2018
forecast issue is for location, timing and amounts in light snow
event late tonight through Saturday morning.

An area of surface convergence along an arctic front should bring
some light snow beginning late tonight. The trend is for the snow
to be further south, generally an inch or two possible across the
southwest forecast area with little or no accumulation elsewhere.

Lake effect snow bands are expected as the cold air, with 850 mb
temps falling below minus 10c, filters in during the afternoon.

The flow is northerly with the best chance for snow along the
sable points and perhaps the far western sections of allegan and
van buren counties. This band should dissipate as it moves inland
with inversion heights crashing as sfc ridging moves in.

Next chance for snow will be Monday as clipper tracks across
northern lower michigan with some lake effect snow showers
persisting into Tuesday. Cold pattern continues into mid week
with a brief warm up at the end of the week.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1243 pm est Fri nov 16 2018
some areas of ifr conditions will linger across lower michigan
this afternoon but the trend will be for improvement with MVFR
expected later this afternoon and evening. Ifr will return late
tonight as light snow moves in from the west. West to northwest
winds could gust to 20 knots at times this afternoon with winds
decreasing this evening.

Marine
Issued at 258 pm est Fri nov 16 2018
no changes to the small craft advisory.

Hydrology
Issued at 1243 pm est Fri nov 16 2018
there are no hydrologic concerns over the next week. Expected
amounts of rain and snow look light. Liquid equivalent of the
current snowpack is under one-half inch, and even when it all melts,
will not cause any notable rises on the rivers.

The threat for ice jams remains near zero through the next week as
daily average temperatures remain above 20 degrees. Warmer weather
is expected towards the end of next week.

Grr watches warnings advisories
Mi... None.

Lm... Small craft advisory until 1 am est Saturday for lmz844>849.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
