.DISCUSSION...
Issued at 216 AM CDT Thu Apr 3 2025

As the low moves northeast out of the Northland, both forcing
and moisture will continue to decrease throughout the morning,
lowering snowfall rates until it ends completely. However, some
brief snow showers may lower visibilities in a short distance
and affect traveling conditions on the morning commute.

We will stay under a colder air mass aloft for the remainder of
the week with highs in the upper 30s to 40s. A cold front
associated with a large low over the Hudson Bay in Canada will
sweep across the Northland Friday into Saturday. Moisture is
very limited with this system (~0.5" PW), and will be battling
lingering dry air. Precipitation should start as virga and then
will mainly fall as snow, but could have rain mixed in during
the afternoon before temperatures decrease in the evening.
Accumulations are expected to be light, if any.

When there is no precipitation, dry conditions will lead to low
RHs across the area with minimum RH lowering each day. This dry
period combined with elevated winds may lead to near critical to
critical fire weather conditions, especially early next week.

The cold pattern continues behind the cold front as the cold air
mass lingers into next week. High temperatures will be in
excess of 10 degrees below normal on Monday, before a warm up
begins mid week closer to normal.

Issued at 619 AM CDT Thu Apr 3 2025

Conditions are steadily lifting as snow begins to dissipate
across the Northland. MVFR to IFR conditions will lift to VFR to
MVFR throughout the day. Strong west to northwest winds will
decrease throughout the day as well as the system exits. Chances
for fog tonight are increasing under clearing skies, and have
introduced MVFR conditions when fog is suspected to occur.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 216 AM CDT Thu Apr 3 2025

Winds out of the northwest will increase for this morning into
the afternoon, with winds up to 30 kts and waves 4-6 ft. These
conditions hazardous to small craft will decrease tonight as the
exiting low pressure system moves further northeast. Small Craft
Advisories are in effect until late this afternoon. Winds will
remain light after today until later this weekend as a cold
front moves through, with likely hazardous conditions with the
front passage.
