As frigid temperatures hit Metro Detroit this weekend, you are at greater risk for frostbite and hypothermia is you’re outside for extended periods of time.  WWJ Newsradio 950’s Beth Fisher spoke with emergency room Doctor Jeff Ditkoff at Beaumont Hospital, where frostbite cases are seen every year.

If you have a mild case of frostbite, Ditkoff says you could try warming up with warm water, but if that’s not working, head to the emergency room.

Ditkoff  also advises dressing in layers when you’re out in this cold weather.

High temperatures will top out only in the teens Sunday, and that’s not the end of it.

The cold snap is supposed to linger all weekend with lows at night in the single digits and the highs only in the teens.

Flame Furnace in Warren was handling a lot of calls, according to Vice President of Sales, Dennis Meteer.

“On a day like today, we’ll do in excess of a hundred service calls.  We sell seven or eight new furnaces,” Meteer said.

With the cold weather expected to continue, Meteer is making sure they have enough staff on hand all weekend.  He says furnaces tend to break down during these cold spells because of the constant demand on them.

Here’s the Forecast:

With single digit temperatures in the forecast for the next few days, The Michigan Humane Society has a life saving reminder — don’t leave your pets outdoors.

Pet owners are urged to take the necessary steps to protect their furry companions from the frigid cold. Even dogs that are normally kept outdoors, should be brought inside. And, that includes large, thick-coated breeds.  To report pets left outside in the cold, concerned neighbors can call the Michigan Humane Society’s Cruelty Hotline. A confidential message can be left 24-hours a day.

For those of us who are sick of the cold and snow and hoping for a quick end to winter, Chief Long Range Forecaster Joe Bastardi may have bad news.

More persistent cold is expected to hold strong through at least the middle of February across much of the eastern two-thirds of the country.  He says this will be quite a change for the Great Lakes and Northeast as compared to last year, when the regions experienced their warmest back-to-back March and April on record.

Bastardi also expects wintry events to last into April in some areas, which would be longer than last year.

Based on what is predicted for the rest of the season, Bastardi also says that this winter could end up being the coldest for the nation as a whole since the 1980s.
