The National Weather Service is putting a big chill on a hot Valentine’s Day tradition, the annual Cupid’s Undie Run Detroit, where people strip down to their skivvies to raise money New York-based Children’s Tumor Foundation.

The forecast calls for a wicked combination of single-digit temperatures, snow and driving wind that will cut through right to your skin during the mile-or-so run – even if you’re fudging on the underwear with Spandex or long underwear.

Bottom line, ‘you have to be comfortable first and foremost,”race director John Marcicky told the Detroit Free Press.

The race is still on, with the party starting around noon and wrapping up about 4 p.m. The race itself starts at 2 p.m.

By then, Detroit will have received a couple of inches of snow and temperatures will be making their plunge to the cellar. Weather.com predicts air temperatures of 14 degrees by 2 p.m., but with 21 mph winds, it will feel like -4. By race’s end, it’ll feel even colder, more like -8.

From that point on, whether you’re running or not, it’s going to be a long underwear, thermal sweatshirt, heavy parka and fleece-lined hat and gloves kind of night Saturday and day Sunday, when the high will top out around 3 degrees. Here’s the teeth-chattering forecast:

Saturday:

5 p.m.: 10 degrees, feels like -10.

6 p.m.: 8 degree, feels like -11

7 p.m.: 6 degrees, feels like -13

8 p.m.: 5 degrees, feels like -15

9 p.m.: 3 degrees, feels like -18

10 p.m.: 2 degrees, feels like -10

11 p.m.: 0 degrees, feels like -20

Sunday:

Midnight: -1 degrees, feels like -23

1 a.m.: -3 degrees, feels like -25

2 a.m.: -4 degrees, feels like -26

3 a.m.: -4 degrees, feels like -26

4 a.m.: -5 degrees, feels like -26

5 a.m.: -5 degrees, feels like -26

6 a.m.: -6 degrees, feels like -26

7 a.m.: -7 degrees, feels like -27

8 a.m.: -8 degrees, feels like -29

9 a.m.: -7 degrees, feels like -27

10 a.m.: -5 degrees, feels like -25

11 a.m.: -3 degrees, feels like -22

Noon: -1 degree, feels like -19

1 p.m.: 1 degree, feels like -17

2 p.m.: 2 degrees, feels like -14

3 p.m.: 3 degrees, feels like -13

The National Weather Service offers a less optimistic – if -29 degree wind chill values can ever be considered optimistic – and said the 40 mph winds from an Arctic blast behind the cold front will make it feel as cold as -35 below in some areas.

Whether it feels like -29 or -35, it’s going to be too cold to venture out if you don’t have to, Dr. Rachel Rohde, an orthopedic surgeon at Beaumont Hospital, Royal Oak, told the Free Press.

“This weekend, it’s the frostbite thing I think a lot of us are worried about,” Rohde said. “It’s very, very bad. People – even if they’re wearing gloves — may not be aware of how cold it is outside.”

DNR Cancels Outdoor Events

The Michigan Department of Natural Resources said Friday that, due to the dangerously cold weather, it has canceled several outdoor programs and events scheduled for this weekend, particularly in the Upper Peninsula..

It’s Michigan’s free fishing weekend. It’s a good idea to call in advance to check for event cancellations. A listing of park phone numbers is available on the DNR’s website at www.michigan.gov/dnr. Contact information also is provided for each event on the DNR’s GO-Get Outdoors calendar at www.michigan.gov/gogetoutdoors.

One of the canceled events is the lantern-lit cross-country ski event at Bewabic State Park, which was scheduled for Saturday.

“The cold temperatures and wind chill will not only make people uncomfortable,” said Bewabic State Park Supervisor Kasey Mahony, “but also may cause weather-related safety risks and injury.”
