Area Forecast Discussion
National Weather Service Grand Rapids MI
326 PM EDT Fri Jul 4 2025

.KEY MESSAGES...

- Small chance of a shower/storm through Saturday; Otherwise Hot

- Shower and storm chances increase Saturday night into Sunday night

- Dry Monday and Tuesday; Rain Chances Wednesday-Thursday

&&

.DISCUSSION...
Issued at 243 PM EDT Fri Jul 4 2025

- Small chance of a shower/storm through Saturday; Otherwise Hot

The SW portion of the area had to contend with some showers and
storms that lingered longer than expected this morning. Those have
since fizzled out quickly as the low level jet and moisture return
have weakened considerably over the last few hours.

We will be left with only small 20-30% chcs of a shower or storm
this afternoon east of U.S.-131. The atmosphere is still quite
unstable with the heat and moisture still around, and upper ridge
building over the area. Forecast soundings show the mid levels
warming a bit with the upper ridge building overhead later this
afternoon and evening. This will essentially cap the atmosphere, and
reduce the small chances of rain even more. This will be the case
through Saturday.

The clouds have limited the heating a bit today for the southern
half of the area. We will see clouds scatter out a bit, and allow
for temps to warm to 90F today. 850 mb temps warming to around 20C
with the heat dome overhead will allow temps to warm into the lower
90s for Saturday. Dew points are not going to be too oppressive in
the low to mid 60s F. This should limit the potential for any type
of heat headlines being needed with heat indices expected to stay
below 100F.

- Shower and storm chances increase Saturday night into Sunday night

The second half of Saturday night will see the cold front to our NW
drop in late. We will see shower/storm chances arrive over the NW
corner of the forecast area after midnight, and then spread SE
through Sunday morning.

The timing of the front and rainfall being focused on late Saturday
night and Sunday morning for a majority of the forecast area will
limit any severe potential a bit. The lack of strong instability
without any help from a diurnal boost will also keep things mostly
tame. In fact it may limit rainfall for the Central and Northern
portions of the forecast area.

Southern areas will see the best instability build with some heating
taking place before the rain/front will move in. Sfc based LI's are
forecast to drop to around -4 to -5C and MU CAPE increasing to over
1,000 J/kg. Even with the best instability, deep layer shear values
are wimpy, with only 15 to 20 knots of 0-6km shear. This situation
looks like it will mainly be a beneficial rain, with little to no
chance of severe weather.

The front will sink south of the area Sunday night, taking the
rainfall with it.

- Dry Monday and Tuesday; Rain Chances Wednesday-Thursday

Once we see the front sink south of the area, dry and cooler weather
should return to the area for Monday. The upper heights drop a bit
as the weekend upper ridge gets flattened well.

Sfc ridging will then dominate over the area Monday through Tuesday.
A flow from the north and east will bring in slightly cooler
temperatures, and much drier air. This will hold over the area until
at least Tuesday evening as the sfc ridge slips east of the area.

Rain chances then look to return to the area for Wednesday and
Thursday, with cooler temperatures holding in over the area. The
upper jet will be dropping in over the Upper Midwest, and allowing a
short wave trough to move over the area. This system will not have
much moisture to work with as we do not see a moist flow set up from
the Gulf ahead of the sfc front. The short wave will mostly act with
diurnal instability to fire a few showers and storms Wed and Thu
afternoons.

There is some uncertainty as to how quick this system moves out
toward the end of next week. We feel it is more likely to move out
by next Friday, but can not rule out it sticking around a little
longer.

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 811 AM EDT Fri Jul 4 2025

The broken line of thunderstorms over Lake Michigan has become a bit
more cohesive and trackable, so MKG and GRR have a narrower time
window and higher confidence for vicinity thunder. Maintained prob30
thunderstorm at AZO, BTL, LAN, JXN for later this morning into mid
afternoon. Mid-level instability is present and this convection
should persist in some form off its own atmospheric perturbations.
Each of the 00Z HREF member models persist these showers and storms
to various extents/intensity through southwest/southern Lower
Michigan today. The threats of the day with any TS include
lightning, IFR visibility with heavy rain, LLWS and gusts around 25
knots.

&&

.MARINE...
Issued at 243 PM EDT Fri Jul 4 2025

We will be issuing Small Craft Advisories and Beach Hazards
Statements for the weekend with this afternoon's forecast cycle.

No problems with winds and waves through Saturday morning with a
lighter pressure gradient in place. Winds will then increase for the
northern half of the marine zones beginning Saturday afternoon. This
takes place as a result of the cold front pressing down closer to
the area. The area of concern for Saturday will be north of Muskegon
with the increasing flow from the SW. The winds will then spread
down a bit further Saturday night to around Holland. Winds will then
switch to become from the NW on Sunday as the cold front moves
through. Areas south of Holland do not look to be as strong as the
north at this time.

Once the wind and waves subside on Sunday afternoon/evening, winds
should stay on the lighter side for a good period of next week.
