The episode as NWS LOT wrote it up.

A 17 year old boy from Minnesota went missing on the afternoon of the 6th while swimming in Lake Michigan near Beverly Shores. He was unable to be recovered. Three others were rescued from the water and transported to a local hospital. A Beach Hazards Statement was in effect at the time advertising 6 to 9 foot waves and dangerous currents along the Indiana lakeshore.

.DISCUSSION...
Issued at 145 PM CDT Tue Aug 6 2024

Through Wednesday Night:

There remains a small chance for a thunderstorm across northwest
IN through mid afternoon. Current activity has been developing
just east of cwa and expect this trend to continue over the next
hour or so. Any thunderstorms that do develop in northwest IN
would likely not have enough time to become strong before
exiting the cwa. After the thunder potential ends, there will
remain a chance of showers or sprinkles into this evening. There
may also be a chance of a few showers across the southern cwa
overnight into Wednesday morning but confidence is too low to
include mention at this time.

A few breaks may develop in the clouds this afternoon,
especially across northern IL. This may allow temps to recover
back into the lower 70s but temps generally around 70 can be
expected through sunset, while temps will fall into the 70s in
the far southern cwa as the cold front exits the area this
afternoon. Low temps tonight will likely be in the upper 50s to
lower 60s for most locations, perhaps warmer in Chicago and near
Lake Michigan. With mostly sunny skies expected Wednesday, highs
may reach 80 for most locations, cooler near the lake.

Northeast winds will continue in the 25-30 mph range over
southern Lake Michigan into tonight, which will allow high
waves in the 6-10 ft range and create dangerous swimming
conditions at Lake Michigan beaches. The winds will gradually
diminish on Wednesday with waves slowly subsiding. Current end
time for the beach hazard statement, which is 3pm Wednesday, may
need refinement, but looks ok for now. cms

Thursday through Tuesday:

The extended forecast period features dry conditions, cooler
temperatures, and comfortable humidity levels as upper level
troughing/closed upper low sets up across the Great Lakes region
late in the week. Temperatures will be the warmest on Thursday
away from the lake with highs in the lower 80s in the afternoon
before a cold front then pushes across the region. The
associated mid-level vort max and surface low remain largely to
the north along with any precipitation chances. Expansive
surface high pressure then sets up across the region in its wake
keeping the area dry into early next week with below normal
temperatures with highs in the 70s.

.AVIATION /18Z TAFS THROUGH 00Z THURSDAY/...
Issued at 100 PM CDT Tue Aug 6 2024

Main Aviation Concerns:

- Ceilings slowly lift through the afternoon into the early
  overnight.

- Low pressure shifts through the southern Great Lakes into the
  Ohio Valley, keeping north-northeast winds in place...at times
  breezy into the evening.

- Skies begin to clear out late tonight into Wednesday morning,
  with winds increasing from the east-northeast.

After morning IFR conditions, ceilings are beginning to lift to
MVFR (1200-1500 ft) early this afternoon and will continue a
slow lift today. North-northeast winds usher additional
moisture off Lake Michigan, and with the slow progression of low
pressure to the east-southeast, cloud coverage will take time
to erode over the next 12 hours. The breezy north-northeast
winds are forecast to linger throughout the afternoon into the
beginning of tonight before gusts ease across much of the area.
Winds slowly veer to the east-northeast Wednesday morning,
while another round of increasing speeds is expected, however
not as gusty as today.
