Clipper passing now, wind chills a factor tonight.

I should have been keeping track of the clippers with a numbering system. Oops. Anyway, another one is going through today. A light band of flurries this morning with another shot of light snow in the early afternoon. The afternoon has also brought gusty west winds, creating blowing snow and wind chills (at my house) 6 degrees below the outside ambient temperature. Surface map source here.

Yesterday was pleasant, out ahead of today's clipper. However, this clipper has begun deepening (despite a lack of moisture) and the pressure gradient has begun cranking up surface winds. Map (to the left) shows the pressure gradient, from Weather @ Unisys.com.

Snowfall amounts this morning were only a trace, this afternoon was less than 0.5", but I've no idea where all the snow blew to.

Winds have been gusting today with the clipper moving by. The Twin Ports (Duluth/Superior) have even seen a gust up near 50 mph. With very cold air being drawn south behind this front and strong winds, wind chills will again be an issue across the region tonight. The coldest air will remain over northern Minnesota, with moderation in temperature as the air moves southward. With forecast low temperatures tonight between -20 and -30, NWS Duluth has issued Wind Chill Warnings for inland northern Minnesota for wind chills between -40 and -50. These wind chill temperatures will be capable of freezing exposed skin in less than five minutes!

Wind Chill Advisories cover the rest of northern Minnesota and the far northwest county of Wisconsin (Douglas)... this includes the cities of Duluth and Superior.

Lake-effect snows will impact the
shorelines of the U.P. of Michigan where various Snow, Lake-effect Snow, and Blowing Snow Advisories are in effect. In addition, the Keweenaw Peninsula has a Blizzard Warning. More information can be found at NWS Marquette's page.

Lake-effect snows could briefly bring some overnight accumulation to Wisconsin's south shore of Lake Superior, but is not expected to be a significant event. NWS Duluth is highlighting the Wisconsin Snow Belt to receive 1 - 4" of snow in tonight's Weather Story.
