— The National Weather Service has issued a freeze watch for much of the Triangle because of a blast of cold air that is headed toward central North Carolina.

The front will trigger showers Friday evening and that rainfall will be followed by some of the coldest air of the season so far.

The freeze watch extend from 10 p.m. Saturday night through 9 a.m. Sunday morning, and temperatures are expected to plunge to the mid-20s to low 30s by early Sunday morning.

"Sunday morning is likely to be the coldest day of the season," said WRAL meteorologist Elizabeth Gardner. "This will put an end to the growing season."

Gardner said the drive home during the Friday evening commute could be wet, with rain starting between 4 p.m. and 5 p.m.

She said some models show suggest that that the heaviest rain could fall to the north of North Carolina in Virginia.

"It zooms right out of here and then we start to clear," Gardner said. "By tomorrow morning, it will be clear and chilly."

The high temperature Friday is expected to top out near 60 degrees before dropping to the low 40s overnight.

Saturday's temperatures will only reach the low 50s before plunging to around 30 degrees for the overnight low.

"Our first hard freeze is expected Sunday morning," Gardner said. "That cold air is not messing around."

Sunday will also be chilly with a high in the low 50s, she said.

The front that will bring Arctic air to the Triangle is also responsible for a round of bitterly cold weather that will grip the Great Lakes Region this weekend and dump several inches of snow in parts of the region.

Lake-effect snow could start as early as Friday in the Upper Peninsula of Michigan, where snow has already fallen on a few occasions this season. Parts of western Lower Michigan should also see lake-effect snow develop off Lake Michigan on Friday.

The National Weather Service issued a warning for parts of the Upper Peninsula with forecasts calling for 9-14 inches of snow that is expected to stretch into Saturday morning.

Forecasters say travel could be difficult with snowfall totals of 6-12 inches possible in other parts of the western Upper Peninsula.

Elsewhere, a blast of wintry weather also is forecast, with 3-5 inches of snow possible in the western and southwestern Lower Peninsula. The region will see temperatures at or below freezing and and parts of southeastern Michigan, including Detroit, could see 1-2 inches of snow.
