.DISCUSSION...
Issued at 302 AM EDT Mon Aug 3 2026

A fairly quiet stretch of weather is expected to start the week
as a departing upper-level disturbance continues to pull
farther into the Northeast. In its wake, expanding mid-level
ridging and accompanying surface high pressure settle across the
Great Lakes, providing a few days of quiet weather to begin the
forecast period. The larger-scale pattern remains progressive
with the aformentioned ridge gradually shifting east as another
wave and its associated cold front approach the region mid-week.
Beyond that, guidance continues to favor a return to broader
troughing across the region through late week into the start of
the weekend before indications of a flatter, more zonal flow
looks to emerge toward the end of the period.

Clearing skies overnight combined with light winds and
lingering low- level moisture has allowed areas of patchy fog to
develop this morning, especially near inland lakes, rivers, and
other favored low- lying locations. After morning fog
dissipates, abundant sunshine and dry conditions are expected
both today and Tuesday with today`s afternoon high temperatures
generally in the 70s to around 80 degrees. Overnight lows
tonight will dip close tot he 40s across the typical interior
cold spots, with the remainder of northern Michigan settling
into the mid 50s. As the surface high pressure shifts east,
developing southerly return flow and continued sunshine should
support a modest warmup Tuesday, with many locations climbing
into the low to mid 80s.

Forecast confidence begins to decrease somewhat by Tuesday
night into Wednesday as the next aforementioned shortwave and
attendant front move toward the area. Increasing large-scale
ascent associated with favorable upper-level jet dynamics will
support a growing chance for showers and thunderstorms, with the
greatest coverage likely occurring sometime Wednesday as the
front crosses the region. Exact timing remains the primary
forecast challenge and will ultimately dictate how much
instability can develop ahead of the boundary. Current
indications suggest enough instability for scattered
thunderstorms, with the potential for a few stronger storms
should greater daytime destabilization materializes. Moisture
also increases ahead of the front, supporting locally efficient
rainfall rates where thunderstorms persist.

Conditions settle back down heading into the latter half of the
week as cooler air filters in behind the front beneath broader
cyclonic flow aloft. While the overall pattern does not appear
particularly active, weak disturbances rotating through the
upper-level trough may be sufficient enough to generate low-end
shower chances from time to time. Seasonable temperatures look
to persist through the end of the week.
