Synopsis
Issued at 323 pm est Wed nov 14 2018
clouds will be on the increase on Thursday as low pressure barrels
up the appalachians with light snow reaching the southern half of
lower michigan during the late afternoon and evening. A total of 1
to 2 inches of snow is possible from grand rapids to lansing and
south to jackson.

Discussion (this evening through next Wednesday)
issued at 323 pm est Wed nov 14 2018
primary forecast issue will be for p-type and amounts on Thursday
afternoon and evening. This will be another case similar to Monday
evening where impacts to travel could be made worse if skin
temperatures fall below freezing, which could happen after dusk on
Thursday.

Most of the model soundings show that this event should start as
snow or change over to snow quickly as the the lower levels
saturate and wet bulb temperatures are below freezing through the
depth of the column. We are looking at about a 6 hour period
roughly from 3 pm to 9 pm where an area of mid-level f-gen would
be favorable for the formation of mesoscale banding across the
southern half of the forecast area.

Skin temperatures will be above freezing at the onset but should
go below freezing around 6 pm to 7 pm with the potential for some
icing on roads after that. Still too early to get a more specific
handle on this, along with confidence on travel impacts. We will
hold off on an advisory for now given the marginal nature of the
event.

After the f-gen banding winds down Thursday evening, a northern
stream shortwave trough axis comes through Friday morning with
some light snow or snow showers across the northern zones. This
shouldn't amount to much. A sfc front generates enough convergence
to bring another round of light snow Saturday morning. Fair and
cold after that, until a clipper brings the chance of more light
snow early next week.

Aviation (for the 18z tafs through 18z Thursday afternoon)
issued at 1245 pm est Wed nov 14 2018
vfr conditions to continue through tonight then ceilings will
lower on Thursday afternoon with MVFR conditions by late
afternoon across southern lower michigan. Wind will be north today
and east on Thursday.

Marine
Issued at 323 pm est Wed nov 14 2018
a small craft advisory will probably be needed on Thursday night
and Friday as winds and waves increase.

Hydrology
Issued at 1022 am est Tue nov 13 2018
river levels are mostly above normal for this time of year, though
they are below bank full and steady or falling. The precipitation
over the next week will be limited in amount and frozen, so rivers
will continue to fall. Despite the cold weather, freeze-up ice jams
are not a concern, as water temperatures in the main-stem rivers are
still well above freezing.

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.
