Area Forecast Discussion
National Weather Service Grand Rapids MI
308 AM EDT Tue Oct 16 2018

LATEST UPDATE...
Synopsis/Discussion/Marine

.SYNOPSIS...
Issued at 308 AM EDT Tue Oct 16 2018

Below normal temperatures will continue this week. A couple of cold
front will move across the state reinforcing the cool air in place.
The best chance of rain looks to be Friday afternoon and evening and
again late Saturday. As colder air flows in late Saturday and
Saturday night, mixed rain and snow is possible.

&&

.DISCUSSION...(Today through next Monday)
Issued at 308 AM EDT Tue Oct 16 2018

Forecast concerns deal with a couple of cold fronts moving through
the state this week.

As a cold front approaches tonight, breezy conditions will develop
this afternoon ahead of it. Southwest winds to 35 mph looks possible
from noon through 5 pm or so before diminishing. The low pushing the
front is near James Bay, so we're not going to see much in the way
of precipitation with it. Tonight will be cold with lows in the mid
30s. Temps in the mid 40s will be all we'll do Wednesday, we'll see
some sunshine.

Friday afternoon and night will be the next chance for precipitation
as a strong cold front moves through. Chances for thunder look
limited at best but there is a weakness in the stability field and
LI's briefly dip below 0c from 00z-06z Saturday so we won't rule it
out.

Highs will be mostly in the 45-50 degree range Saturday. A secondary
cold front is progd to move south Saturday afternoon and mostly
affect the northwest half of the cwa. This front has a strong short
wave associated with it and so we have showers in the grids during
this time. As h8 temps drop to -8c Saturday night, the rain showers
will mix with and change to light snow. Minor slushy accums across
the northern cwa are possible.

Another cold front Monday will move through the state and give us a
chance of rain late in the day.

&&

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 148 AM EDT Tue Oct 16 2018

Impactful winds are expected at the southern Lwr MI terminals today.
Expect winds to increase out of the southwest quickly after 12Z,
with sustained speeds around 20 kts and gusts around 30 kts most of
the day. Wind relaxing this evening to around 10 knots and becoming
west-northwest.

VFR cigs this morning around 4000 ft giving way to mid level clouds
around 10,000 ft after sunrise. A few rain showers are possible
after 00Z tonight as lower clouds around 4000 ft move back in with a
cold front.

&&

.MARINE...
Issued at 308 AM EDT Tue Oct 16 2018

The main change to the headlines was to upgrade to a Gale Warning
north of Holland through 00z. Southwest gales to 35 knots are
likely. Elsewhere southwest winds to 30 knots can be expected.

&&

.HYDROLOGY...
Issued at 135 PM EDT Mon Oct 15 2018

Despite light rainfall this morning resulting in totals at most of a
quarter inch in areas along the lakeshore, water levels continue to
fall following continuous rain last week. Into this week, our next
chance for light precipitation will return Wednesday and again
Friday as a cold front moves through the area. No significant
rainfall is expected to impact waters levels for the next several
days.
