.DISCUSSION...
Issued at 117 PM CDT Wed Sep 24 2025
Current Conditions/Today:
Quiet weather pattern for the Northland as an upper level low has
stalled out over the Great Lakes region with upper level ridging
arching across the northern Rockies into the Northland. At the
surface high pressure resides over the region allowing for gradual
warming with highs this afternoon expected to climb into the mid and
upper 70s away from Lake Superior. Overnight we may still see some
fog develop as radiational cooling looks to still have some low
level moisture to work with. However, the latest high res guidance
is not nearly as excited about the potential as we have seen the
past several days.
Stronger west to southwesterly winds tomorrow out ahead of a cold
front will see temperatures soar into the mid and upper 70s with a
few low 80s possible. Given the forecasted wind direction, Lake
Superior will not be providing any relief to our coastal zones.
Precipitation chances with the passing cold front late Thursday do
not look overly impressive. Model soundings show an abundance of dry
air in the mid and upper levels which will largely limit any rain
productions. For now, we have kept PoPs below 15% but may see some
sprinkles.
Another cold front moves across the region on Saturday. Similar
story as the previous with not a lot of moisture to work with.
Better moisture profiles look to be farther north but could see some
low chances (15%) across northern MN. Afterwards, we remain dry with
increasing temperatures through the work week. An omega blocking
pattern will keep things steady as the anticyclone will be held in
place over the Midwest through midweek before a trough manages to
nudge in from the west. Expect temperatures to climb into the mid an
upper 70s again. For context that is 10-15F above normal for this
time of year.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 624 PM CDT Wed Sep 24 2025
Patchy fog is expected again tonight, but with lesser coverage
of dense fog and nearing terminal limits than the previous few
mornings. Expect a mainly dry frontal passage Thursday mid-day
to evening. This will largely be seen as a wind shift from
southwesterly to westerly to northwesterly from 15Z Thursday -
03Z Friday. A few rain showers though cannot be ruled out in
northern Minnesota after 18Z and beyond this TAF period.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 117 PM CDT Wed Sep 24 2025
Fog continues to be the main concern for the nearshore waters.
Current webcams paired with satellite imagery shows An area of
dense fog lingering from Grand Marais and up through Grand Portage.
Model guidance would suggest this will linger through the day and
well into tomorrow with the chance for expansion as we head into the
evening hours. The better chances (60%) for the fog expansion will
be along the North Shore, but can`t fully rule out the chances (40%)
for the South Shore. Winds continue to be less than 5 kts with
minimal wave action until Thursday afternoon when winds of 5-10 kts
start to stream in from the west.
