DISCUSSION

Issued at 335 PM CST Sat Feb 7 2026

High pressure stretched from Hudson Bay into the western Great Lakes and Mississippi Valley this afternoon with an elongated frontal boundary across the Plains with multiple areas of low pressure analyzed along it. Radar was showing returns over northeastern Minnesota into northern Wisconsin, but with dewpoint depressions over 10 degrees, most of this was virga. A few snowflakes were reaching the ground in spots, however, with sporadic reports of -SN. This is in association with a weak shortwave propagating through the northwest flow. Models have come in drier and further east with this feature with CAMs basically dry. Have pulled back POPs with this update and lowered snowfall amounts across the Arrowhead. Little to no snow accumulations are now expected. Still can't rule out some spotty freezing drizzle, but forecast soundings don't show much support for this either. Any precipitation chances this evening and tonight will be along and east of I-35/US53, with the best chances in the Arrowhead.

Flow turns more zonal Sunday with an area of low pressure moving across the Canadian Prairies. This will set up a warm front along or to the north of the International Border. This will keep most of the precipitation across northwestern Quebec, but southerly flow off Lake Superior may lead to some light snow/mix showers along the North Shore with upslope flow.

Zonal flow will remain in place to begin the new week before breaking down late week as ridging moves across the central CONUS. This will bring warmer air into the Upper Midwest resulting in highs running above normal. Highs will reach into the 30s for most of the region with some 20s in northern areas Tuesday and Wednesday behind a stronger clipper passing to the north. High pressure then looks to keep dry conditions in place for much of the remainder of the week.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1143 AM CST Sat Feb 7 2026

VFR conditions are expected to prevail through the period. Snowfall chances have trended down and further east with this update, so have removed from the forecast. Southeasterly winds will back southerly overnight and become lighter.

MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/

Issued at 335 PM CST Sat Feb 7 2026

Marine concerns are minimal over the next 48 hours. Winds will generally remain under 15 knots out of the south Sunday then southwest for Monday. Some stronger gusts to 25 knots will be possible Monday morning ahead of a clipper passing to the north. The strongest winds will be east of Grand Portage, so overall coverage will be low.
