Synopsis
Issued at 306 am est Wed nov 14 2018
sunshine is expected to return for at least part of Wednesday to
contrast a very cloudy month so far. Temperatures will still be
well below normal but winds will be light and variable. The next
system approaching from the south will spread snow into a portion
of lower michigan during the latter half of Thursday, possibly
creating slick spots on untreated roads (especially bridges) after
dark. Cold temperatures persist into early next week, though
significant precipitation does not appear likely.

Discussion (today through next Tuesday)
issued at 306 am est Wed nov 14 2018
starting to see erosion of the low-level clouds on satellite in
far southern michigan. Though we are optimistic that subsidence,
falling inversion heights, dry air, and boundary layer flow
shifting north and east will eventually defeat the lake-effect
clouds, it may take until late morning for clearing north and west
of gr. Grand rapids has not had a day yet this month with more
than 25 percent of possible sunshine. We have had 20 days in a
row of mostly cloudy skies. The surface high pressure center will
be passing through this afternoon, so winds will be light.

Moisture and lift spreading in from the upper-level low to our
south on Thursday will produce light precipitation in a portion
of the area, beginning late morning or afternoon from south to
north. Initially this precip aloft and at the surface may
encounter temperatures a little above freezing, though evaporative
cooling should convert any mix to snow fairly quickly. Expecting
a majority of precip to fall as snow with wet-bulb temperatures
through the profile holding just on the cold side of 0 c.

Snow liquid ratios likely to be rather low with a thin and high
dgz, and most of the moisture and lift focused in temperature
layers favoring plate and column crystal habits, not to mention
some riming. Overall, amounts an inch or less are expected. Models
have trended farther north again, now placing all areas
south east of holland to clare in a fair chance for snow.

Some concern for slick spots on untreated roads after dark
Thursday evening with temperatures a little below freezing.

Could get a little (freezing) drizzle mixing in overnight into
Friday. Despite the cold surface temperatures, the mid-level
inversion at or warmer than -10 c should keep a lid on lake effect
shower potential over the weekend, though some flurries are
possible.

Aviation (for the 12z tafs through 12z Thursday morning)
issued at 645 am est Wed nov 14 2018
skies will continue to clear from south to north this morning. By
15z or so all of our TAF sites will be clear. Winds will be light
and become variable as surface high pressure moves over the area.

A storm moving this way from arkansas for tomorrow will bring
increasing high and mid clouds toward sunrise Thursday.

Marine
Issued at 306 am est Wed nov 14 2018
winds are relaxing and waves diminishing for Wednesday. Southerly
winds Wednesday night into Thursday may cause waves to flirt with
small craft advisory conditions off big sable point. Small craft
advisory conditions are possible Friday as winds become more
westerly.

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.
