.DISCUSSION...
Issued at 338 PM EST Mon Nov 4 2024

- Periods of showers and maybe a few thunderstorms to continue
  tonight and Tuesday

A wet past 12 hours has occurred with everyone seeing rain in the
area. Rainfall amounts have been heaviest in the Grand Rapids area
with amounts of 0.60 of an inch to a little over an inch per
radar estimates. The wet weather will continue both tonight and
Tuesday before rain ends Tuesday night as a deep southerly flow of
moisture laden continues to stream into the area. A deepening
surface low will move from the Southern Plains northward into
Wisconsin by late afternoon on Tuesday. As the low steadily
deepens during this time frame the moisture transport will
increase due to both an increase in wind speeds in the lowest
5,000 feet and an increase in moisture (PWATS increase to 1.6 to
1.7 inches which is off the charts for this time of year.

HREF 4hr max reflectivity shows a distinct push of heavier rain
into the area towards midnight that will continue overnight and
into Tuesday morning. This will be coincident with at strong LLJ
moving through the area on the order of 50-65 knots. Another
burst of heavier rain will occur Tuesday afternoon and evening
along and ahead of the cold front. Rainfall amounts in the
heaviest swaths will likely be around 3 inches if not higher when
all is said and done Tuesday night. Again, these amounts over the
course of the time it is falling should not produce flooding
outside of some ponding of water due to clogged drains from
leaves.

AT this point have decided against a Wind Advisory given the
amount of clouds and rain showers around tonight and Tuesday.
Inland areas should be very marginal with regard to advisory
criteria (45 mph gusts) likely ending up in the 40-45 mph range in
many areas. The exception could be the Lake Michigan shoreline and
we may need to take another look at this as new model data comes
in this evening. As for now, holding off on any wind headlines
over land.

- Wet Weekend

High pressure will from the northern Plains to the East Coast from
Wednesday through Saturday. The eastward movement will help low
pressure over the Central Plains to move northeastward on the back
side of the high into Minnesota by the weekend.

Clouds will begin to increase Saturday as the low makes it's way
toward the Great Lakes. Strong short wave support will create decent
isentropic lift on the eastern flank of the low and we'll see rain
develop Saturday night from southwest to northeast as condensation
pressure deficits fall to less than 10 mb. Rain will continue
through Sunday as the accompanying occluded front passes through and
then wrap around moisture from the low.

Highs in the 50s are expected through the period.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1229 PM EST Mon Nov 4 2024

Radar shows we are entering a lull in the precipitation that will
last into the evening. However, the next wave will quickly move
north with another batch of showers and embedded storms just prior
to midnight. The precipitation with that will end around 08z after
which we'll be looking at MVFR cigs.

&&

.MARINE...
Issued at 311 PM EST Mon Nov 4 2024

We look to continue on Lake Michigan with south winds to 30 knots
this evening and tonight. Therefore our current Small Craft
Advisory headline through 700am Tuesday looks great. Winds to 30
knots equates to a high end SCA and waves will run 4 to 8 feet
tonight. Around daybreak, we begin to mix deeper and into higher
momentum air with 40-50 knots in the mixed layer. We have opted to
issue a Gale Warning on the back end of the SCA from 700am Tuesday
into the early morning hours of Wednesday. South to southwest
gales to 40-45 knots look likely. Waves will correspondingly jump
in magnitude given the increase in wind to 8-12 feet north of
Holland. Winds and waves will make a slow decline on Wednesday.
