.DISCUSSION...
Issued at 408 AM EDT Mon Jul 7 2025

- Clearing out with less heat and humidity today

Early morning low stratus and drizzly rain showers will gradually
lift and clear out from northwest to southeast during the day.
High temperatures will be closer to seasonal normals today, in the
lower 80s in most spots, with lower dew points in the upper 50s
to mid 60s. More information on the potential late-day increasing
swim risk (beach hazards) in the Marine section below.

- Almost daily chances for showers or storms Tuesday night into
  the weekend

Quasi-zonal but relatively weak 500 mb flow with a few shortwaves
rippling through, plus gradually increasing heat and moisture in
the the low levels, will support frequent chances for showers or
thunderstorms popping up between Tuesday night and the weekend.
Per ensembles, chances are relatively higher between Tuesday night
and Wednesday afternoon, then Friday night through Saturday
evening in association with the more pronounced upper-level
shortwave troughs.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 121 PM EDT Mon Jul 7 2025

Skies are clearing from west to east this afternoon with all sites
breaking from MVFR into VFR conditions over the next few hours.
Once a terminal breaks out into VFR, that will continue through
this evening before a moderate (30-40 percent) chance of MVFR fog
develops overnight at AZO, BTL, and JXN. Confidence is too low for
TAF inclusion but will continue to monitor. Scattered clouds at
or above 10kft arrive Tuesday morning with scattered showers
approaching MKG by the end of the TAF window.

.MARINE...
Issued at 408 AM EDT Mon Jul 7 2025

Waves in the nearshore are coming down following yesterday`s
evening increase in winds and waves. Winds from the north becoming
northwest and increasing this afternoon will trend conditions
toward a late-day moderate to high swim risk (beach hazard)
for Muskegon county and south. Combination of post-cold-frontal
high pressure nudging into the U.P. and the afternoon development
of the lake breeze circulation will intensify winds toward 18-20
knots in the nearshore off Muskegon, Grand Haven, and Holland, per
the HREF mean. This is a scenario that often yields a moderate
becoming high swim risk late in the day for Muskegon State Park,
Holland State Park, and South Haven North Beach.
