An arctic blast has settled over Metro Detroit, keeping temperatures below normal through the end of the workweek, the National Weather Service said.

After topping out at 20 on Monday, readings could dip to around 9 by early Tuesday: far from the average low of 25 for the date and closer to the record minimum of 2 set in 1948, weather service records show.

Light snow showers are likely before 4 p.m. Tuesday as the mercury struggles to reach 21, 20 degrees below normal.  Wind chill values as low as minus 5 are possible as wind gusts reach 25 mph.

On the state's west side, the weather service has issued a winter weather advisory for Mason, Lake, Oceana, Newaygo, Muskegon, Ottawa, Kent, Allegan, Barry, 
Van Buren and Kalamazoo counties through 7 p.m. Tuesday. Some 2-5 inches of snow are expected, with wind chills around minus 5 to minus 15.

In southeast Michigan, the forecast for Wednesday and Thursday stays frigid, with highs in the 20s and lows in the teens.

The thermometer is not set to rise above freezing until Friday.


"We'll see a warming trend towards the end of the week," said Trent Frey, a meteorologist with the National Weather Service in White Lake Township. "By Saturday, a low pressure system will develop over the plains and its winds will bring warm air to the north, lifting the area into the mid-40s."

On Sunday, highs could reach 50.
