Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Today’s Weather:
As of 4 PM CST…Strong low pressure of 984 mb was centered near the Apostle Islands (South Shore of Lake Superior in Northwest Wisconsin) wet snow, heavy at times was occurring on the northwest side of this low Today in Northeastern Minnesota with locations closer to Lake Superior into Eastcentral Minnesota and Northwestern Wisconsin continuing to see the wet snow mix with drizzle and light rain at times. This storm we had this weekend is something more typical in October or November, not January, as the higher elevated areas away from Lake Superior has seen heavier snowfall totals compared to locales closer to the lake, pretty unusual to see something like this in late January. High temperatures Today continued to be well above average with mainly 30s across our area while 850 mb temperatures as of 4 PM ranged from -1 to -3 degrees C. Winds Today were out of the north or west under 20 mph.
Today’s 500 mb analysis:
Broad upper level trough (528 meters) covered the Northern Plains/Central Plains/and Upper Midwest This Afternoon per RUC model analysis and water vapor satellite imagery. Strong shortwave was lifting rapidly N/NW across the Upper Great Lakes late This Afternoon with a deformation snow area setting up across Northeast and Northern Minnesota late Today. An upper level low was found in Eastern Nebraska and Western Iowa This Afternoon per water vapor satellite imagery with movement toward the east. Strong 120-180 meter 12 hour 500 mb height falls were occurring Today across the Central and Northern Great Lakes due to this deepening storm.
Tonight:
Low pressure of 984 mb near the Bayfield/Ashland Wisconsin areas late Today will lift north-northwest toward the Northwestern tip of Lake Superior by late Tonight, pressures with the low will deepen further and should get down to between 978-981 mb by late Tonight. Snow wrapping around the low will be most widespread in Northern and Northeast Minnesota Tonight, mainly affecting Cook, Lake, and Northern St. Louis Counties…Snow will also occur for the remainder of our area Tonight, but should be somewhat lighter and a bit more sporadic compared to areas farther north. Some lingering drizzle and light rain will also continue This Evening close to Lake Superior, down through Eastcentral Minnesota into Northwest Wisconsin. Lows Tonight will settle into the 20s to low 30s with increasing north or west winds at 10-25 mph.
Monday and Monday Night:
Deep low pressure will be tracking E/NE across Northern Lake Superior on Monday and will then track into Eastern Canada by Monday Night. Wrap-around snow showers will persist across our area on Monday with flurries coming to an end by Monday Night. Highs Tomorrow will be in the 20s and 30s, but expect falling daytime temps with teens and 20s by the Afternoon. Lows Tomorrow Night will range from around 10 below to 10 above zero. Gusty northwest winds from 15-30 mph will be common across our area during this period with a few higher gusts even possible. Wind chills by Tomorrow Night will likely drop into the single digits, teens, and 20s below zero across our area…
Final snowfall amounts from this storm will go as follows:
3-7″ across all of Northwest Wisconsin, back through the Twin Ports, through Eastern and Northern Minnesota with 7-12″ snow totals expected along the Higher Terrain of the North Shore of Lake Superior in Northeast Minnesota.
Extended Forecast:
Main influence on our weather during the extended period will be a polar vortex across Central Canada, this will cause a northwest/northerly flow to develop across the Upper Midwest most of this week…End result will be for a much colder weather regime for our area with mainly dry conditions expected from Tuesday through Friday the way it looks now. High temps Tuesday and Wednesday will be in the single digits and teens with lows Tuesday Night and Wednesday Night in the single digits, teens, and 20s below zero.
Lake effect snow update:
With arctic air moving in behind the deep low during the Monday-Tuesday period and with a northwest-north wind coming off Lake Superior, the stage will be set for some lake effect snow from Douglas County through Bayfield, Ashland, and Iron Counties in Northwest Wisconsin. The threat for lake effect snow will be greatest east of the city of Superior. Snowfall accumulations will range from 3-7″ between Monday and Tuesday with some locally higher totals possible.
Note: Driving conditions will continue to be hazardous Tonight through Tomorrow Night across Northern Minnesota and Northwest Wisconsin due to the wet slushy snow on the ground…Any standing water and slush on roads will freeze and turn to ice as temperatures drop Monday and Tuesday. Use extreme caution if you need to travel Tonight through Tuesday Morning.
