FXUS63 KDLH 020543 AFDDLH Area Forecast Discussion National Weather Service Duluth MN 1143 PM CST Sun Feb 1 2026 .KEY MESSAGES... - Flurries persist overnight before tapering off in coverage after Midnight and pre-dawn hours Monday. - Colder air arrives tonight on northwest winds, dropping wind chills to 20 below zero for some places by Monday morning. - A warming trend develops mid-week, followed by another clipper on Thursday that brings a chance for rain and snow. && .DISCUSSION... Issued at 139 PM CST Sun Feb 1 2026 A clipper continues to traverse the Northland this afternoon, bringing cloudy skies and widespread light snow and patchy freezing drizzle. While accumulations for most areas will remain in the 1 to 2 inch range, southwesterly flow may slightly interact with the terrain along the North Shore enhancing snowfall rates, where isolated totals of 3 to 4 inches are possible. Any icing is anticipated to only be a light glaze. Satellite Cloud Top Phase RGB's and radar dual pol signatures highlight the fzdz areas quite well with nice areas of near-zero ZDR and high CC in the presence of reflectivity in the system's dry slot. As the system exits to the east this evening, a cold front will sweep across the region. Winds will shift from southwest to northwest and remain gusty, ushering in a colder airmass. Any lingering snow showers will taper off from west to east tonight. Overnight lows are expected to drop into the single digits above and below zero, with wind chill values dipping as low as 20 degrees below zero by Monday morning. High pressure builds in for the start of the work week, bringing clearing skies but keeping temperatures on the cooler side for Monday. A gradual warming trend kicks in Tuesday and Wednesday as temperatures climb back into the 20s. Attention then turns to Thursday, when a more organized clipper/low pressure system is forecast to move through the Upper Midwest. This system will likely draw warm air northward, pushing highs into the 30s and introducing the potential for a messy mix of rain and snow with snowfall amounts giving another inch or two if we stay in the colder air. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1122 PM CST Sun Feb 1 2026 VFR and MVFR stratus with light snow showers linger across the Northland. Up and down conditions will continue for the next several hours, which have been denoted as PROB30s in each TAF. As dry air moves in from the northwest, snow will begin to end, but MVFR conditions will remain. && .MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/... Issued at 859 PM CST Sun Feb 1 2026 Northwest winds gusting to 25 knots are expected tonight behind a passing cold front that brings a colder air mass into the Northland. A Small Craft Advisory has been issued for the entire North Shore lasting through 10 AM as a result. Winds decrease Monday afternoon and remain fairly light into Tuesday.
