Synopsis
Issued at 324 am edt Mon mar 27 2017
low pressure will pull away from lower michigan today with showers
ending. Another low will track across indiana and ohio tonight
with some showers across southern lower michigan. Fair weather
should return for Tuesday and Wednesday.

Short term (today through Wednesday)
issued at 324 am edt Mon mar 27 2017
somewhat drier air is slowly advecting into lower michigan this
morning and the areas of fog across the northern forecast area
should gradually dissipate. Showers will also be tapering off and
ending this morning as the low center pulls away, but another low
is poised to our south. The northern edge of its precip shield is
progged to reach into roughly the southern half of the forecast
area from late afternoon through the evening then move east after
midnight.

Showers should taper off by Tuesday morning with drier and cooler
northerly flow setting up as canadian sfc high builds south and
provides fair weather through Wednesday.

Long term (Wednesday night through Sunday)
issued at 324 am edt Mon mar 27 2017
the main weather maker during the long term will be a southern
stream low that moves from the southern plains through the great
lakes Thursday and Friday. Both the GFS and ECMWF are similar in
their handling of this system. A strong push of moisture northward
from the gulf will accompany this system. At the same time, high
pressure over western quebec will feed cool air into the state. The
result will be mixed rain and snow Thursday morning turning to a
cold rain Thursday afternoon. Temps will rebound into the 50s Friday
through Monday after the low moves east and high pressure moves in.

The ECMWF shows another southern stream system next Monday clipping
the southern CWA as it moves over the ohio valley. Meanwhile, the
gfs is farther south across the southern states.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 732 am edt Mon mar 27 2017
ifr and lifr conditions will continue this morning before
conditions improve to MVFR and possiblyVFR this afternoon.

Conditions will go back down to MVFR and ifr tonight with the best
chance for ifr across southern lower michigan where low clouds and
rain can be expected.

Winds will be west AOB 10 knots through the afternoon then turn
north less than 10 knots tonight.

Marine
Issued at 1101 am edt Mon mar 27 2017
areas of dense fog are affecting the coastline, in addition to
open waters. Visibilities of one-quarter mile are less could
extend into the afternoon before drier air begins to move in.

Otherwise, winds and waves will be relatively light through the
next couple of days.

Hydrology
Issued at 300 pm edt Sun mar 26 2017
rainfall totals over the last couple days have ranged from a quarter
inch across western reaches of the muskegon and grand river basins
to a swath of 1 to 2 inches across central and eastern stretches of
the grand river basin as well as central and western reaches of the
kalamazoo river basin. Rises on area rivers are occurring, though
most should hold within banks. Some exceptions will be at ionia,
hastings, eagle, and holt where minor flooding may impact areas
adjacent to the river banks.

Additional rainfall later this upcoming week will likely hold many
rivers at higher than normal levels.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
