Area Forecast Discussion
National Weather Service Grand Rapids MI
330 AM EST Sat Nov 12 2016

LATEST UPDATE...
Synopsis/Short Term/Long Term/Marine

.SYNOPSIS...
Issued at 330 AM EST Sat Nov 12 2016

A dry weekend is forecast, with the next chance of rain not coming
until Tuesday afternoon. Skies will vary between mostly clear and
partly cloudy through the weekend. A weak cold front will move into
the area on Monday, but with limited moisture no precipitation is
forecast. Low temperatures dipped into the 20s in many areas this
morning and even the teens across portions of Northern Lower
Michigan. We will slowly rebound to around 50 today for highs. Mid
50s high temperatures are forecast for Sunday and Monday.

&&

.SHORT TERM...(Today through Monday)
Issued at 330 AM EST Sat Nov 12 2016

A quiet weather pattern is anticipated through the course of the
short term. The main focus is on some breezy conditions as we will
be in a fairly tight pressure gradient from this afternoon into
Sunday night.

As far as the winds go, breezy conditions can be expected across
Central Lower Michigan today and over most of the area on Sunday.
Sunday in the lakeshore counties will likely be the windiest place
and time over the weekend. BUFKIT profiles at MKG and LDM would
suggest we could see gusts of 30-40 mph. Sub advisory conditions,
but it will be noticeably windy towards the lake tomorrow.

Lake generated stratocumulus can be seen in satellite imagery
tonight streaming into into Illinois in northeast flow. As the winds
come around more to the west this morning, we expect some of this
cloud to push into Southwest Lower Michigan. Partly cloudy
conditions for a time today as these clouds work inland and
dissipate.

Otherwise dry with upper ridging in place much of the weekend. A
shortwave pushing across the northern plains on Sunday night will
knock down the ridge and bring more of a zonal flow into Monday. The
shortwave aloft will push a cold front into the area but with
limited moisture in time/height cross sections not anticipating
anything more than an increase in some clouds on Monday.

.LONG TERM...(Monday night through Friday)
Issued at 330 AM EST Sat Nov 12 2016

We are looking at a couple rounds of rain in the long term, one
chance late Tue/Tuesday night, and another on Friday. Otherwise near
to slightly average temps can be expected most of the period.

The chance of rain we had in for Tue night now is looking to move in
just a little bit earlier for Tue afternoon into Tue night. This chc
will be a bit better than the chc for Mon with the first front as
the upper short wave will be a bit further south and stronger.
Still not much Gulf moisture to tap however.

We will see drier air then move in for Wed-Thu with temperatures
rebounding quickly after a brief cool down. The sfc ridge in the
wake of the Tue front will move through on Wed. We will then see a
strong srly gradient become established as a large trough across the
West intensifies a system across the Plains. This will give the area
another chance of seeing 60 degree temps on Thu into Fri.

Rain chances will reappear then on Fri at this time. The system
gaining strength across the Plains will lift NE toward the region on
Fri. This is looking to be a fairly strong front with a nice shot of
cold air trying to wrap into it on the backside for next weekend.

&&

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1252 AM EST Sat Nov 12 2016

We are expecting mainly VFR conditions through this forecast
period. The exception to this will be at KGRR and KMKG where some
lake effect cloud cover based around 2500 ft may shift onshore as
the winds become SW this morning. Otherwise skies will be mainly
clear with only some high clouds possible.

Some gusty winds will become possible by this afternoon,
especially at the wrn terminals. Wind gusts of up around 25 knots
will be possible across the west. Inland areas will see them drop
off after dark tonight. KMKG will likely see the gusts stay up,
and possible even increase more tonight being closer to the
relatively warmer lake as inland areas cool off.

&&

.MARINE...
Issued at 330 AM EST Sat Nov 12 2016

Issued a new Small Craft Advisory beginning this afternoon north of
Holland and tonight south of Holland extending to Monday morning. A
tightening of the pressure gradient will begin today and stretch
into Sunday night. The gradient will be provided by a low moving
across southern Canada and an area of high pressure situated over
the Ohio Valley. It appears to be another event with solid 20-30
knot winds which should push waves into the 5 to 8 foot range. It
will be a rough weekend on the big lake.

&&

.HYDROLOGY...
Issued at 314 PM EST Fri Nov 11 2016

Area rivers are all below bankfull and falling, but many in the
Grand River basin remain above normal for November. No significant
rainfall events are expected in the next week, so levels should
continue to fall.
