.DISCUSSION...
Issued at 129 PM CDT Sun Aug 9 2026

For the rest of the day, mainly widely scattered rain showers
and possibly (10-20% chance only) an isolated non-severe
thunderstorm are forecast this afternoon for inland northwest
Wisconsin. The main hazard if any non-severe storm could come to
be would be a quick burst of localized heavy rainfall and
cloud to ground lightning. Meanwhile, smoke aloft departs
slowly to the southeast with some blue skies returning into this
afternoon across the Northland. Quiet conditions take over
tonight as temperatures dip slightly below normal under light
winds. However, the next round of smoke aloft moves in tonight
and sets up for Monday.

This incoming smoke layer will be creating sky cover for areas south
of US Highway 2 throughout the day on Monday. Aside from the hazy
skies, Monday will feature pleasant conditions with near-normal
daytime high temperatures climbing into the upper 70s to lower 80s
across the area. Humidity levels will drop a bit, creating a
comfortable feel for mid-August. Light variable winds in the morning
will eventually turn toward the west and northwest during the
afternoon hours.

Heading into the rest of the week, a persistent northwest flow aloft
continues as a stalled frontal boundary to our south keeps us on
the cooler side. This northwest flow continues to create near-
normal daytime high temperatures in the 70s to lower 80s, and
slightly below normal low temperatures each night falling into
the mid 40s to lower 50s.

Within this northwest flow will be weak and small-scale
disturbances helping create the off-and-on mainly rain shower
with embedded non-severe thunderstorm chances every 36 to 48
hours. Any showers and storms would likely be very localized and
short-lived in nature from this setup of shear, moisture and
instability-limited environmental progs in longer-range ensemble
guidance.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 1235 AM CDT Mon Aug 10 2026

Fog the main concern for the next several hours, with a mixture
of mid and high level clouds and generally light north winds at
less than 5kts. Visibilities should be reduced to MVFR
conditions for KDLH, KHIB, KBRD and KHYR. The lowest conditions
should be found at KHYR, where a period of IFR visibilities can
be expected. Fog should dissipate and visibilities to improve
between 12z and 13z for all sites. Once the fog dissipates, VFR
conditions are expected through the remainder of the TAF period.

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 121 PM CDT Sun Aug 9 2026

Winds across western Lake Superior will remain light for the rest
of the day and tonight, generally out of the northeast to southwest
at 5 to 10 knots. Waves will remain at 1 foot or less through
tonight. On Monday, west winds will shift to the southwest and
increase to 10 to 15 knots, with afternoon gusts up to 25 knots
possible, especially north of Taconite Harbor along the far
North Shore. A Small Craft Advisory may be needed in time for
the Grand Marais to Grand Portage zone Monday afternoon and
early evening. Winds will diminish again by Monday night,
becoming northwest at 5 knots.
