Flurries and local snow squalls are expected to begin Tuesday afternoon and continue into Wednesday.

Local snowfall amounts 5 to 10 cm are possible on Tuesday and amounts of 15 to 25 cm are possible Tuesday night. Local blowing snow reducing visibilities to near zero will also be a concern.

Local snow squalls are expected to taper off when the winds shift to southwest on Wednesday.
