Severe Weather Alert Day declared

Severe winter storm on schedule for Metro Detroit area

By Paul Gross - Meteorologist

DETROIT - After 1 to 3 inches of snow overnight (the lower amounts are to the south, and the higher amounts to the north), there could actually be a bit of a "lull" Sunday morning, with just light snow falling.

Then snow will increase during the afternoon, and become heavy with snowfall rates of an inch per hour possible. As a result, the National Weather Service has issued a Winter Storm Warning for all of southeast Michigan.

We could even see thundersnow! If you manage to record any snow with lightning or thunder, please send it to us at, or tweet it to us at #4StormPics.

Steady temperatures in the mid to upper 20s. Wind eventually shifts around to the north at 10 to 20 mph.

Heavy snow early tapers off Sunday night after midnight. Storm total snow accumulations should average 6 to 10 inches across the metro area, with over 10 inches possible north of I-69.

Temperatures fall sharply to near zero by Monday morning, with a northwest wind of 15 to 25 mph creating wind chills near -20.

Many schools will probably be closed Monday, as well as Tuesday and possibly even Wednesday due to the extreme cold. With wind chills this cold, it would not surprise me to see the National Weather Service issue a rare Wind Chill Warning for Monday night and Tuesday morning.

Then we hit the severest Arctic outbreak we've seen in many years. Monday night's low of -10 could shatter our current record of -5, set back in 1942, and if our official daytime high Tuesday doesn't get above zero, it'll be the first time this has happened since January 19, 1994...I remember that day well: it was the coldest day in recorded Detroit weather history!

This is a very severe stretch of winter weather ahead. We'll keep you posted here online, on our free weather app (just search for "WDIV" in the app store) and on Local 4 News. And don't forget that you can follow me on Twitter at @PaulGrossLocal4.
