‘Dangerously cold’ weather coming to Triangle over Christmas. Latest updates here.

The Triangle isn’t forecast to get a white Christmas this year, but that doesn’t mean it won’t be extremely cold — “dangerously cold” says the National Weather Service — in the days leading up to and on the holiday.

The NWS is forecasting that an arctic front will move through the Triangle Friday morning, bringing brutally cold temperatures and gusty winds to the area. Cold temperatures will stick around through much of the Christmas weekend, making for a colder-than-normal holiday.

To learn more about the cold and freezing conditions and what Triangle residents can expect, The News & Observer spoke with James Danco of the NWS Raleigh office.

Here’s what to know.

When does the super cold weather move into the Triangle?

Danco outlined the following timeline for when the arctic front and cold weather will move into the Triangle, and how long it will stick around:

The arctic front that will bring the “really cold air” will come through the Triangle on Friday, likely around mid-morning.

When the front first comes through, it will bring “very gusty” winds, with gusts up to 40 to 50 mph. As the day continues, gusts will be closer to 30 to 40 mph.

The National Weather Service on Thursday issued a Wind Chill Advisory for much of central North Carolina, including the Triangle, that will go into effect Friday at 7 p.m. and last through 9 a.m. Saturday.

How cold will it get?

High temperatures in the Triangle on Friday are forecast to be in the low-40s, with “temperatures crashing down” to the 30s and 20s by the afternoon, then dropping into the teens and single digits overnight.

“Associated wind and sharply colder temperatures will create wind chill values between zero and 10 above late Friday through Saturday morning,” the NWS’ Hazardous Outlook for this weekend’s weather reads.

On Saturday, “the winds aren’t going to be as bad” — but temperatures in the Triangle will still be “quite cold,” with a high of just about 30 degrees.

“That is way below normal, like more than 20 degrees below normal,” Danco said, and could set a record for the lowest maximum temperature on that date.

By Saturday night, temperatures will again reach the teens.

What’s the weather forecast for Christmas Day?

By Sunday, Christmas Day, the weather will “start to moderate a little bit, but it’s still going to be cold.” The forecast shows a high in Raleigh on Sunday of 35 degrees.

In the days following Christmas, temperatures will continue to warm up, with highs likely reaching the 40s — “still below normal but not like brutally cold, like what we’re going to see Friday into the weekend.”

Will there be rain or snow?

Before the bitterly cold front moves in early Friday, the Triangle will be in for a wet day on Thursday, rainfall totals in Raleigh “between three quarters and one inch possible,” the NWS forecast reads.

The chance for rain sticks around until before noon on Friday, the forecast reads.

As the cold moves in and the rain continues for a brief period, is winter precipitation possible?

“It’s not totally out of the question,” Danco said, but don’t expect more than a few snowflakes — and definitely don’t expect accumulation.

“The rain looks to be fairly light on Friday, so I don’t think that is a major concern,” Danco said. “And you know, with the strong winds and crashing dew point, it’s gonna get so dry, that there’s going to be a lot of evaporation going on. So I don’t think that that’s really a major concern.”

How to prepare for cold, NC State of Emergency

With such cold weather on the way to the Triangle, it’s a good idea to take time now to prepare.

Gov. Roy Cooper on Tuesday signed a State of Emergency order “to activate the state’s emergency operations plan, waive transportation regulations to help the transport of fuel and critical supplies, help first responders and protect consumers from price gouging.”

“We know that with the extremely low temperatures North Carolinians will need propane and other heating fuel to keep their families warm,” Cooper said in a news release announcing the order.

“While propane supplies are strong in the state, there is a limited supply of licensed commercial truck drivers, which is being further exacerbated by COVID and flu outbreaks. The State of Emergency will help ease some restrictions and allow heating fuel companies to keep up with demand.”

Danco recommended the following tips to prepare for the brutally cold temperatures:

▪ Try to stay inside as much as possible during the coldest periods — Friday and Saturday — but if you have to go outside, make sure to dress appropriately for the weather, wearing multiple layers, hats and gloves.

▪ Keep an emergency kit close by in your home and your car. Include items like food, water, extra clothes and blankets.

▪ Take steps to protect your home, including weatherizing, winterizing and insulating doors, windows and pipes.

▪ Keep your thermostat set to a temperature that will keep yourself and pipes warm. If you live in a rental, your lease may include information about the minimum temperature allowed during the winter.

▪ Don’t forget about your pets. Bring them inside to keep them warm.
