333 AM EDT Sat Jun 22 2024

.KEY MESSAGES...

-Potential severe weather and flooding today/this evening

-Dry Monday, strong storms possible Tuesday/Tuesday night

-Dry Wednesday/Thursday, storminess returns next weekend

&&

.DISCUSSION...
Issued at 332 AM EDT Sat Jun 22 2024

-Potential severe weather and flooding today/this evening

A warm front has lifted to the northern cwa early this morning
where it's expected to become quasi stationary today. Low pressure
in Nebraska will move ENE toward Wisconsin by this afternoon. A
strong southwest flow ahead of the low is helping to bring in
moisture-rich air and precipitable water values in excess of 2
inches is expected today.

There will be some destabilization ahead of the low across the
northern and central cwa today. Thunderstorms will likely spread
east from Wisconsin. CAPE values are not particularly impressive.
However, shear values increase to 45 knots this afternoon. An
impressive LLJ is progd to move toward the northwest CWA this
afternoon. A weak short wave aloft will aid in convective
generation. It's possible that as the shear increases we could see
some low topped supercells develop. Impressive helicity values
around 400 m2/s2 move over the northern rows this afternoon near
the frontal boundary. It's not out of the question a tornado or
two could spin up along the boundary.

As the low crosses northern Lower around 00z, the trailing cold
front will begin to move south. Showers/storms will form along the
cold front and move across the rest of the cwa during the evening
and overnight. Areas south of I-96 will likely see a bit more
destabilization today due to a bit more sunshine. And so any
storms that form along the cold front will be able to tap into
that instability. Strong wind gusts and torrential rainfall will
be the main threats. Precipitation will be ending by Sunday
morning.

Today will be the last day of the Heat Advisory. Heat indices will
top out in the mid 90s again today. A cold front will move across
the state tonight leading to highs in the 75 to 80 degree range
Sunday.

-Dry Monday; strong storms possible Tuesday/Tuesday night

Monday will feature sunshine and comfortable temps/humidity with
surface ridging in control before a warm front returns on Tuesday
and sends back the heat and humidity for a day. GFS has SB Capes
exceeding 3000 J/KG Tuesday afternoon once the warm sector arrives,
setting the stage for the possibility of some stronger storms by
evening as a cold front and H5 shortwave trough approach from the
northwest.

-Dry Wednesday/Thursday; storminess returns next weekend

The cold front exits early Wednesday and we dry out by afternoon as
cooler/drier air arrives from the north. High pressure settles in
for Thursday with dry weather still prevailing, but then models
diverge which leads to low confidence timing the return of our next
chance of showers and storms. The more progressive GFS has rain
chances returning already on Friday whereas ECMWF holds off until
Saturday.

&&

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 205 AM EDT Sat Jun 22 2024

The cluster of showers and storms currently over srn WI and nrn IL
extrapolates northeast into MKG around 11-12Z and should last on
and off through much of Saturday morning. These may impact GRR as
well although probably to a lesser extent than MKG. Ocnl MVFR/IFR
possible as these storms pass through. After the morning
convection it looks like the MKG/GRR terminals may dry out and go
predominantly VFR for this afternoon before more showers and
storms return after 00Z this evening.

Otherwise VFR weather prevailing all day for the terminals south
and east of GRR with the bulk of the rain and tstms remaining
off to the north over central and nrn Lwr MI. The potential for
showers and storms does not really ramp up across this area until
after about 02-03Z tonight. Winds increasing to 12-22 kts out of
the southwest by Noon today.

&&

.MARINE...
Issued at 332 AM EDT Sat Jun 22 2024

Wind and waves will increase behind a cold front tonight
necessitating a Small Craft Advisory and Beach Hazards statement
south of Grand Haven. Wind and waves will decrease late tonight.
Additionally, thunderstorms will pose a threat to boaters and
beachgoers today and tonight.

&&

.HYDROLOGY...
Issued at 332 AM EDT Sat Jun 22 2024

Very juicy air with precipitable water values north of 2 inches
are expected across the cwa today. A stationary frontal boundary
over the northern cwa will focus showers and thunderstorms today.
Any of these storms will be capable of producing torrential
rainfall. Training echos will be an issue today and local
probability matched mean values hint at the potential for 2 to 4
inches of rain along US-10 in an area that saw locally heavy
rainfall from storms yesterday. As a result, we have issued a
Flood Watch for the northern 3 rows of counties from noon today
through 6 am Sunday. Local flooding of poor drainage areas is
possible.
