DETROIT – The snowfall schedule and extent of snow accumulation for this week in the Detroit area are increasingly coming into focus.

Dangerous weather conditions

Due to varying weather conditions, we are issuing a 4Warn weather warning for Wednesday evening through Thursday morning.

• Lake snow is accumulating, with the possibility of snow squalls.

• Gusty winds that may blow between 30 and 40 miles per hour.

• Subzero wind chills will prevail through Thursday morning, only feeling in the single digits by the afternoon.

How much snow will there be?

The winter storm watch on the western side of the state will be upgraded to a winter weather advisory or winter storm warning at some point as possibly 4 inches to more than a foot of snow is forecast off Lake Michigan before Thursday evening.

These snow bands are spreading across this side of the state, bringing up to 3 inches of snowpack where the bands are heaviest.

Timeline

A few snowflakes will begin flying Wednesday morning, but heavier bands will form after midday.

It will snow more heavily during the evening, especially on Wednesday after 7 p.m.

They will probably move out before sunrise. But in some models, the snow will remain during the Thursday morning commute.

As temperatures drop, salt will no longer be as effective on Thursday.

Power outages and wind chills

With wind gusts of over 50 km/h, power outages could occur again, similar to last week.

But wind chill will be most noticeable. Feeling temperatures will fall below zero by Thursday morning and remain in the single digits through the afternoon and even into Friday morning.
