Wind chills 5 below to 15 below zero are expected this morning and again tonight into Friday morning. Bundle up before heading out. These cold conditions may also lead to river ice formation and possible ice jams.
Light winds and very cold temperatures tonight may result in the development of freezing fog overnight into early Friday morning. Should this occur, some slick spots will be possible early Friday morning. Otherwise, we are expecting periodic chances for wintry precipitation Friday night, Saturday night into Sunday morning and next Monday night.
This is an early heads up for what looks to be shaping up as an active weather pattern for the Great Lakes region. Multiple "Alberta Clipper" type disturbances will likely produce swaths of snow Saturday night onward, though it's too early to offer more specifics. Prepare and plan ahead for the potential for fairly frequent travel impacts. As always, stay tuned for the latest forecast updates!
