Area Forecast Discussion
National Weather Service Grand Rapids MI
129 PM EDT Fri Oct 30 2020

LATEST UPDATE...
Aviation

.SYNOPSIS...
Issued at 323 AM EDT Fri Oct 30 2020

- High winds Sunday with scattered snow showers

- Moderating temps mid to late next week

&&

.DISCUSSION...(Today through next Thursday)
Issued at 323 AM EDT Fri Oct 30 2020

-- High winds Sunday with scattered snow showers --

A consensus of latest short to medium range guidance continues
to show potential for wind gusts to reach 40 to 50 mph with higher
gusts to around 55 mph possible near the Lake MI shoreline in
a strong nw flow caa regime Sunday. A wind advisory will eventually
be needed for (at minimum) the lakeshore counties and quite
possibly for our whole fcst area Sunday. Scattered power outages
will be possible.

In addition scattered lake effect snow showers are expected as h8
temps fall to around -8 to -10 C yielding delta t/s in the mid to
upper teens. Temps will fall through the 30s early Sunday morning
and then stay in the 30s during the day. The falling temps and
scattered snow showers could cause some slick spots to develop on
area roads.

Any snow accumulations should be rather light (under an inch)
largely due to the very strong winds and limited airmass
residence time over the lake. Any potential for accumulations
is also limited by relatively mild pavement/ground temps.

-- Moderating temps mid to late next week --

Medium range guidance continues to indicate the upper level
pattern will become rather zonal by mid to late next week.
This and southwesterly flow will allow for a significant
moderating trend of temps. High temps by midweek will reach
well into the 50's to near 60 degrees.

&&

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 129 PM EDT Fri Oct 30 2020

The general trend of the forecasts will be for a clearing trend
this evening, with wind gusts developing Saturday morning.

Clouds are widespread this afternoon, with ceilings VFR for most
of the area. There are a couple of isolated pockets of MVFR near
the lakeshore, but these should lift to VFR. Skies are expected to
clear toward and just after sunset. Winds will become light and
variable.

Only a few high clouds are expected on Saturday through 18z. Winds
will be the biggest impact with wind gusts developing by late
morning. Highest winds will be toward KMKG where speeds could
approach 30 knots, and a little less speed toward KJXN. Winds will
come up more everywhere beyond this forecast period.

&&

.MARINE...
Issued at 323 AM EDT Fri Oct 30 2020

Winds and waves will increase again Saturday out ahead of the
approaching cold front. Gale force winds are possible as early as
Saturday afternoon and then likely after fropa Saturday night
through Sunday into Monday.

The northwest gales and cold air advection will cause wave heights
to ramp up to around 10 to 14 feet Sunday. Some lakeshore flooding
and erosion is certainly possible. A gale watch has been issued from
Saturday afternoon through early Monday morning.
