LATEST UPDATE...
Aviation

.DISCUSSION...(Today through next Friday)
Issued at 344 AM EDT Sat Jul 23 2022

-- Round of showers and storms early this morning --

Showers and storms are beginning to fill in from Southern Lake
Michigan westward into Eastern Iowa at 300am. This activity is
located on the axis of the low level jet and within a zone of
850mb moisture transport. Roughly the same setup will remain in
place through daybreak with an increase in 850mb transport across
Southwest Lower Michigan. The HREF supports an increase in showers
and storms into our area the remainder of the night, likely
peaking in coverage around 12z. The storms will gradually shift to
the south and east by the midday hours of Saturday. This
convection is elevated in nature which makes locally heavy rain
and hail the two main threats. Storms will repeat over the same
areas so some localized flooding is possible late tonight and into
Saturday morning towards South Haven and Kalamazoo. PWAT values
surge from 1.1 inches to 1.7 inches in the next 6 to 8 hours. This
low level surge in moisture will produce more storms and storms
that are capable of locally heavy rain. 1-2 inch rains in a short
amount of time are certainly in the realm of possibilities. The
stronger updrafts will be capable of hail towards 1 inch in
diameter early this morning.

We expect the storms to tail off during the morning hours as the
low level jet loses steam. In fact we see skies turning partly to
mostly sunny this afternoon which will allow for air mass recovery
where storms occur this morning.

-- Another more significant, likely severe round this evening --

A shortwave in the mid levels will race east-southeast across the
Northern Plains today and reach the Western Great Lakes this
evening. A weak surface low will be associated with the mid level
wave which will bring a warm front back into the heart of the GRR
forecast area by this evening. The wind fields late this afternoon
and evening respond to the mid level wave with increasing winds at
both 850mb and 500mb. The 850mb low level jet increases to 35-45
knots and the 500mb mid level jet increases to around 50 knots.
For mid summer in the Great Lakes it doesn't get much better.
Instability should be more than enough for severe weather with the
higher values west of Lake Michigan, 3000-4000 J/KG of MUCAPE. We
should see values at least in the 2000-3000 J/KG range. Several
runs of the SPC HREF have been showing a squall line move to the
vicinity of Lake Michigan around 00z give or take a couple of
hours. Given the instability and strong winds through the depth of
the convective layer, severe weather looks likely Saturday
evening in Southwest Lower Michigan. We are expecting a rapidly
moving squall line to sweep into and through the area Saturday
evening. To early to nail down the intensity of the winds, but
severe levels are very possible. Therefore, we agree with the SPC
upgrade to an Enhanced severe weather outlook for our area.

The convection will likely move the effective front into the
Southern Great Lakes overnight Saturday night into Sunday and we
will likely see additional storms training over Southern Lower
Michigan during this time frame. A threat for heavy rain and
flooding will continue into Sunday afternoon for these areas.

-- Mid week upper trough digging into the Great Lakes --

Sunday night into Tuesday will largely be dry with high pressure
situated over the area at the surface. It will cool off some
during this time frame as 850mb temperatures drop to around 10C on
Monday.

An upper trough will develop over the Great Lakes from Wednesday
night into Friday. A better chance for rain looks to occur
Wednesday into Thursday with the passage of a cold front.

.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 754 AM EDT Sat Jul 23 2022

Latest trends/expectation is for tstms to remain mostly south and
west of the srn Lwr MI terminals this morning, although can't
completely rule out thunder and briefly/locally gusty winds at
AZO/BTL/JXN through 14Z. Otherwise VFR weather expected today
followed by showers and storms arriving from the west after 00Z
tonight.

Wind gusts in excess of 45 kts and hail are possible tonight with
any line/cluster of storms that passes through, but confidence in
timing of any strong/severe storms at the terminals is too low at
this time to nail down. Later updates to the TAFS will attempt to
fine-tune those details and hopefully contain more specificity of
such threats.

&&

.MARINE...
Issued at 344 AM EDT Sat Jul 23 2022

Two main concerns for the marine interests of winds and storms
this morning and again tonight.

A low level jet over the area this morning will likely kick up a
wave field at least into the 2-4 foot range. A bit ago the
southern Lake Michigan buoy was gusting to around gale force
actually. These type of low level jet events usually result in
waves rolling into the beaches at daybreak. The Small Craft
Advisory was issued for this exact reason yesterday and we have
maintained it through 200pm today from Whitehall southward.

There will be a brief lull in the activity Saturday afternoon and
early evening before another low level jet moves in this evening.
The LLJ will be accompanied by a squall line that will produce its
own wave field. So, we are expecting to need another Small Craft
Advisory tonight, but we want to see how this morning's SCA plays
out first. We may be able to shift gears into a new SCA and
possible Beach Hazards Statement at midday for this evening into
Sunday.
