.DISCUSSION...
Issued at 341 PM CDT Wed Oct 8 2025

High pressure was in control across the Upper Midwest this
afternoon leading to mainly clear skies across the region. Winds
were light and variable across most of the Northland with more
southerly winds across central Minnesota near the periphery of
the high. As the high moves to the east tonight into Thursday,
southerly return flow will set up across the Northland with
winds gusting to 20 to 25 mph. This will also bring in warmer
air with highs reaching into the 60s. Dewpoints will trend
higher through the day as some low level moisture works in
helping to alleviate the very dry conditions and near-critical
fire weather conditions experienced today.

An upper low will drop southeastward from Manitoba into Ontario
Thursday night and then over Lake Superior on Friday. A cold
front will move through the Northland bringing chances for a few
showers, mainly across the Arrowhead into northwest Wisconsin
Thursday evening into Friday. Any QPF amounts are expected to be
light with this system. Cooler air will arrive behind the front
with near normal highs Friday in the middle 50s to middle 60s.
High pressure will dry things out for Saturday with highs
trending above normal once again in the 60s with upper 50s along
the North Shore with onshore flow off Lake Superior.

Low pressure will emerge from the northern Rockies into
Saskatchewan Sunday with a cold front extending into the
Northern Plains. Moisture advection ahead of this front across
the western Great Lakes will bring rainfall chances to the
Northland for Sunday into Monday morning when the cold front
passes. High pressure then returns to start the week before
another chance of rainfall returns for midweek. Temperatures
will trend near normal for the new week with highs in the middle
50s to middle 60s.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
Issued at 1225 PM CDT Wed Oct 8 2025

VFR conditions will prevail through the period. High pressure
will bring light and variable winds today before shifting to the
east tonight. Southerly winds then pick up for tomorrow with
gusts to 15 to 20 knots developing by mid to late morning. A
southwesterly low-level jet will move into the region late in
the period and may bring some LLWS to INL.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 341 PM CDT Wed Oct 8 2025

High pressure will keep winds light and variable for the
remainder of the afternoon. As the high begins to shift east
tonight, winds will turn southerly/southwesterly and begin to
increase to 6 to 12 knots with gusts to 15 to 20 knots by
daybreak. Winds further increase for the afternoon and evening
hours, primarily along the North Shore east of Silver Bay and
across the Outer Apostle Islands, to 10 to 20 knots with gusts
to 25 knots. Small Craft Advisories will be possible mainly from
Grand Marais to Grand Portage during the afternoon and into the
evening hours. These winds will generate waves of 2 to 5 feet.
Winds then swing around to the northwest early Friday morning as
a cold front passes.
