Metro Detroit weather: Heavy snow moves in tonight

Winter Weather Advisory begins at 12 midnight, tonight

DETROITA winter weather advisory is in effect for Lenawee, Monroe, Washtenaw and Wayne counties from 12 midnight, tonight, to 10 p.m. Sunday.

Welcome to Saturday evening, Motown.

Tune up your snow throwers or limber up for snow shoveling. Snow is on the way before the weekend is done. This evening remains dry and cold. Temps remain well below freezing across the entire region tonight. Snow arrives shortly after midnight. Roads and sidewalks become more treacherous, Sunday, with some of the heaviest snow during breakfast.

Saturday evening will be cloudy and cold with steady temps in the upper 20s. Our next snow storms will be brewing to our southwest. The first flakes begin falling south of I-94, in Lenawee and Monroe Counties, by 10 p.m. and afterward.

Saturday night will be snowy across Detroit and the rest of southeast Michigan shortly after midnight and through Sunday morning. Overnight lows will be in the middle 20s.

Snow on the way

Snow will be migrating from south to north overnight. After our South Zone, Detroit and Ann Arbor roads become more slippery, then areas north of Eight Mile Road become snowier in the pre-dawn hours of Sunday. The cities of Flint, Lapeer and Port Huron will have snow falling by breakfast Sunday.

Sunday will be snowy and cold. Snow will fall hardest, Sunday morning. Light to moderate snow will fall consistently late Sunday morning and most of the afternoon. Snow becomes a bit more scattered late Sunday afternoon and Sunday evening. Highs will be in the low 30s.

Snow totals

Sunday night becomes less snowy, but it remains cold -- so roads remain treacherous. Then, the wind from the north will kick in because of the counter-clockwise circulation around the area of low pressure. The wind off Lake Huron, which is mostly liquid, will deliver lake effect snow showers and snow squalls on Monday.

Accumulations will be greater where snow begins first. Neighborhoods south of I-94 will receive four to six inches of snow; isolates spots, over six inches. From I-94 (to the south) and M-59 (to the north), Detroit, Westland, Ann Arbor to Howell, Pontiac, Shelby Township and Mt. Clemens will get two to four inches. One to three inches of snow will fall north of M-59.

Highs will be near 30 degrees Monday afternoon as lake effect snow adds an additional one to three inches of snow across most of the area.

Tuesday and Wednesday will be sunnier and will give Detroiters time to clean up and recover. Remember not to overexert yourself. Pace yourself and take frequent breaks while removing snow and ice. Highs will be in the low 30s, mid-week, with mostly to partly sunny skies.
