.DISCUSSION...
Issued at 142 AM CDT Sun Sep 28 2025
Get ready for a stretch of beautiful early-fall weather across
the Northland as a large area of high pressure settles in for
the entire week. Were looking at an extended period of dry and
sunny conditions with temperatures gradually warming to levels
that are above normal for this time of year, a pattern that
should hold steady right into the beginning of October. The main
exception to this quiet weather will be a push of cooler air
off Lake Superior on Monday afternoon and evening, which will
bring a quick cooldown and some gusty northeast winds,
especially for areas near the Twin Ports. With the steady
drying trend all week, fire weather conditions may become a
concern. While there is a slight chance some moisture could move
into the region on Thursday, confidence in any rainfall is low.
Looking ahead to next weekend, while some forecast models hint
at a pattern change, this type of stable and pleasant weather
often sticks around longer than expected.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1228 PM CDT Sun Sep 28 2025
VFR conditions prevail through the TAF period with high pressure
over the region. South to southwest winds with gusts to 15-20 kt
continue for northeastern Minnesota terminals through early
this evening before weakening tonight. Can`t rule out some LLWS
at INL/HIB later this evening and tonight due to the development
of a roughly 35 knot southwesterly low-level jet, but this
threat should drop off towards 29.07Z to 29.10Z. Winds remain
light out of the south to southeast into daytime Monday, though
onshore northeast winds off of Lake Superior towards late Monday
afternoon and evening could locally enhance winds at DLH.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 142 AM CDT Sun Sep 28 2025
For mariners along the North Shore, expect breezy southwest
winds to develop this afternoon with gusts up to 25 knots.
However, be prepared for an abrupt and significant reversal of
conditions on Monday afternoon. A developing pressure gradient
will cause winds to rapidly switch to the northeast, with gusts
of 25 to 30 knots spreading down the North Shore and across the
head of the lake. This sudden shift will generate hazardous,
choppy seas and bring a surge of much colder air to the Duluth-
Superior area. Conditions are expected to deteriorate very
quickly, so mariners are urged to take all necessary precautions
to avoid being caught off guard by this rapid change.
