The cold wind chills continue to be the main story for the next
several days. Expanded the wind chill advisory to all of our WI
counties as coverage of the -25 F values were fairly widespread
and occurred at bus stop hours. Another round of wind chill advisories
expected tonight as we only rise above criteria for a few hours
Steep low level lapse rates and strong winds are rocketing quite a
few cellular snow producing showers through the area which can be
seen on radar imagery. There may be a short-lived reduction in
visibilities in these showers, but overall they are not producing
much snowfall accumulation due to their speed. Lake effect snow
should be occurring along the south shore, but appears to be
fairly light in nature.
High pressure builds today under a cold air mass. Winds remain
elevated keeping wind chills brisk.
Friday afternoon an elongated short wave passes overhead for
another round of light snow.
The extended forecast period continues to show bitterly cold
temperatures and wind chills continuing through mid-week next
week, with a few chances of light snow Saturday and Monday
Snow accumulations Friday night should be light, with only up to one inch possible over northwest Wisconsin and lighter amounts elsewhere. We
barely get time to breathe before another shot of snow increases
Saturday morning and afternoon, mainly across our southern counties.
Skies look to clear and winds should weaken as surface high pressure builds into the region. Radiational cooling should lead to low temperatures Sunday morning ranging from the lower 20s below zero over the north,to the lower teens below zero over northwest Wisconsin. This should lead to the coldest wind chills of the long-term period, with wind chills
between -25 to -40 degrees across northeast Minnesota.
