Chicago Weather: Heavy, Wet Snow Up To 10 Inches; Lakeshore Flood Advisory With Waves Up To 11 Feet

CHICAGO (CBS) -- A winter storm warning is in effect for the Chicago area until 6 p.m. Sunday. A lakeshore flood advisory is also in effect this weekend until Monday morning.

Expect to see precipitation increase Saturday afternoon and arriving in Chicago after 3 p.m. It might begin as a mix due to warm temperatures but will quickly shift to all snow.

Rain & snow (and a brief wintry mix possibly) will sweep from the southwest to northeast across the area on Saturday.  It should turn to mainly snow by the evening and arrive in the city around 5 or 6 p.m.  Heavy wet snow will fall hardest from around 6 p.m. Saturday to around 2 a.m. Sunday.

Accumulation late Saturday through daybreak Sunday should be around 5 to 10 inches by the time it's all said and done, making it easily the biggest snowfall of the season so far, and the biggest of the past few years.

Strong east winds gusting to 30 mph or more will blow the snow and cause additional problems with visibility.

Lakeshore flooding is also possible with waves building to 8 to 11 feet.  Patchy blowing and drifting snow early Sunday.  This is shaping up to be the biggest two-day snowfall total in over 2 years (at least).

Saturday night: Heavy wet snow with strong winds and reduced visibilities. Temps holding steady in the lower 30s.
Sunday: Patchy blowing and drifting snow early. Cloudy, blustery with light snow at times. High in the lower 30s.

  • Total accumulations from this storm around 5" to 10" with a few isolated spots possibly approaching a foot.

Extended: Dry Monday through Wednesday. Rain changing to snow late Thursday. More snow possible late Friday into Saturday. Much colder by next weekend with highs in the teens possibly on Saturday. This would be the coldest air of the season so far.
