Some light snow showers lingered across parts of the Northland this morning in the wake of the first clipper system. The second clipper was taking shape across the Dakotas and will track along the I-94 corridor in Minnesota today and bring light snow to our southern zones. The low track has shifted a little further south, which will reduce the effects across the Northland. Light snow showers will start around sunrise in the Brainerd Lakes area and then spread north and east through the morning. This activity is expected to remain south of the Iron Range and end for most by sunset, lingering into this evening across parts of northwest Wisconsin. With the shift south of the low, snowfall amounts have gone down. Accumulations of around an inch or less will be possible across northwest Wisconsin and south of US2 in Minnesota. As colder air starts moving in this afternoon, light snow showers and flurries will be possible for areas generally along and north of the Iron Range into the Arrowhead. Some stronger snow showers will be possible downwind of Kabetogama and Rainy Lakes. These snow showers will linger tonight before ending around daybreak Saturday as drier air moves in. Snowfall amounts in this area will be around a half inch or less. Not to be left out, northern Iron County will see lake-effect snowfall taking over as the synoptic snowfall from the low to the south ends tonight and linger into Saturday. Accumulations of 1 to 2 inches will be possible in this area. Highs today will be in the teens and 20s with lows tonight in the single digits above and below zero.

Most of the weekend looks dry and cold with highs in the teens and single digits above zero for Saturday and Sunday along with lows in the single digits below zero. Another clipper looks to pass well to our south Saturday night into Sunday and may clip our southern areas with some light snow showers.

Heading into the new week, northwest flow will remain in control with multiple chances for snowfall. The first will be a clipper in the Monday-Monday night time frame followed by a stronger clipper for Tuesday into Wednesday. Additional snow chances will be seen later in the week as the pattern remains active. Temperatures will overall remain below normal through the week, but will creep closer to normal Tuesday before more cold air arrive Wednesday dropping temperatures back well below normal for the remainder of the week.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/

Issued at 532 AM CST Fri Dec 5 2025

MVFR to IFR ceilings will prevail through the day today as a system passes to our south. Models continue to shift the snowfall further south and have reduced snow to VCSH at BRD and HYR with this update. Some light flurries cannot be ruled out elsewhere today, but they should not have any impact on VSBYs. CIGS are expected to improve to MVFR this afternoon and remain there for the remainder of the period. Some VFR conditions may arrive at BRD late in the period. Winds will be light for the most part, but there is a cold front expected to move through this afternoon that will lead to northwesterly winds gusting to 15 to 20 knots.

MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/

Issued at 425 AM CST Fri Dec 5 2025

Westerly winds will diminish through the day and become northwesterly tonight. Winds speeds will be around 6 to 12 knots with gusts to 15 to 20 knots. The northwesterly winds will increase tonight to 10 to 20 knots with gusts to 25 to 28 knots. This will lead to conditions hazardous to small craft, especially across the Outer Apostle Islands. Winds then diminish Saturday morning to 5 to 15 knots and remain there into Sunday.
