Lake Vermilion Area Weather – January 22-24

Issued at 417 AM CST Wed Jan 22 2025

Snow continues for at least parts of the Northland this
morning, with a band of snow extending from the Virginia/Eveleth
area southeast across the southwest arm of Lake Superior and
onto the Bayfield Peninsula, continuing southeast into northwest
Wisconsin. This band of snow is being driven by a nice
frontogenesis feature ahead of the surface low that is slowly
advancing into northern MN from the northwest as of 3 AM, and
will continue to press east through this morning. By mid morning
this band will be east of the forecast area, but precipitation
will shift to lingering snow showers/flurries in the cold air
advection and steep low level lapse rates. There may be some
more vigorous showers along the leading edge of the colder air
with the cold front, but do not expect anything strong enough to
be considered a snow squall. For now, the main band of snow may
produce another inch or two of snow before it moves out, but
the lingering snow showers are not expected to produce any
measurable snow, especially with the gusty winds expected today
behind the low center. Today temperatures will remain near to
below normal with highs mainly in the teens. Tonight we are
expecting another cold night despite the lingering cloud cover,
though not as stupidly cold as we have been the last few days.

Lake effect snow will continue to affect the south shore behind
this system through Thursday, bringing another 24-36 hour
period of light snow, with 1-2 inches/6 hour time step.
Localized amounts of up to 6 inches are possible, but have held
off on any headlines at this time due to fluctuations in wind
and moisture available.

Our next clipper system looks to pass across the region Friday
afternoon through Saturday. For now this system appears to have
the better dynamics missing the forecast area to the north, and
will probably have lighter accumulations through a longer
duration, producing another 1 to 2 inches for mainly far
northern Minnesota, with lighter amounts to the south.

After Saturday, we have some additional intermittent chances
for light snow with fast moving clipper systems into next week.
Temperatures return to near normal for the most part, though we
may also have a few shots of cold air. We are not looking at
another extended period of frigid temperatures like we had the
last few days.

AVIATION

Issued at 529 AM CST Wed Jan 22 2025

A clipper moving through the area this morning has brought MVFR
to IFR visibilities and MVFR ceilings in light snow. Snow will
exit from west to east this morning, with MVFR stratus expected
to continue though visibilities will improve to VFR. This
afternoon, northwest winds will become gusty to about 20kts, and
ceilings will vary between SCT and BKN, but returning to VFR in
the 22z-02z time range. Winds should also diminish to less than
15 kts by 06z tonight.

MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR

Issued at 417 AM CST Wed Jan 22 2025

Southwest winds gusting to near 30 knots this morning will
gradually veer into the northwest this afternoon and tonight as
a low pressure system moves across Lake Superior. The northwest
winds will be strong and gusty overnight, also gusting 25 to 30
knots, producing building waves, especially along the South
Shore. Small Craft Advisories have been extended until Thursday
morning for most of western Lake Superior. Winds and waves will
diminish on Thursday. Winds to back around to the west Thursday
night before increasing once again out of the southwest on
Friday. A period of hazardous conditions for small craft on the
lake is expected through the weekend.
