Update (4:30 p.m. Friday): Snowfall accumulations of 3-10 inches are expected across much of central North Carolina, according to the National Weather Service. In the Triangle, the latest forecast shows 8-10 inches of snow expected in Raleigh and 6-8 inches in Durham. At this point, meteorologists can’t predict exactly which areas will receive more or less than the forecast amounts. The snow is expected to have cleared out of the area by Sunday morning, Feb. 1. Wind chills Saturday night, Jan. 31 into Sunday morning could be at or below zero; for those who must go outside, meteorologists recommend bundling up and limiting time outdoors. Sunshine is expected Sunday and Monday, Feb. 2, to help with melting.
Update (1:15 p.m. Friday): In a briefing, meteorologist Nick Petro at the National Weather Service in Raleigh emphasized that snowfall totals may vary widely place to place. Models are showing different scenarios, and some places may get far more or less snow than is in the official forecast. Snow is expected to reach the Triangle on Friday night; by 9 p.m., people should be off the roads, staying at home or wherever they plan to be throughout the duration of the storm, until it’s safe to drive again.
As the anticipated storm approaches the Triangle, meteorologists at the National Weather Service have fine-tuned their forecast for snowfall amounts.
As of Friday morning, Jan. 30, the forecast calls for 6-8 inches of snow throughout the Triangle. However, localized amounts vary.
According to the National Weather Service, some areas may get 10 inches or more of snow. Those higher totals are most probable along the Interstate 95 corridor to as far west as the Triangle. Reasonable high-end snowfall totals may surpass 12-14 inches.
On the other hand, there may also be places that receive less snowfall than the forecast amount. There is still uncertainty about which places may receive more or less snow.
Snow is expected to begin falling in central North Carolina Friday evening and will continue through Sunday morning, Feb. 1.
When it falls, snow is expected to quickly start sticking due to cold temperatures.
Unusual as it is for the Triangle, snow is the only kind of precipitation expected to come with this storm, meteorologists said.
With snow in the forecast, Gov. Josh Stein declared a new state of emergency Thursday, Jan. 29. The North Carolina Department of Transportation will apply salt and sand to the roads on Friday, and drivers are asked to stay off the roads starting Friday night.
Black ice could be a concern Sunday night into early next week.
Strong winds, extreme cold expected
The other two hazards associated with the storm, besides snow, are gusty winds and frigid temperatures.
Wind gusts from the north will range from 25-35 mph Saturday, Jan. 31 and Sunday in central North Carolina, but some infrequent gusts up to 40 mph are possible, mainly along and east of the I-95 corridor.
Gusty winds could cause reduced visibility and blowing and drifting snow, along with scattered power outages.
In the Triangle, temperatures Friday night will fall into the teens. On Saturday, high temperatures will climb into the 20s before falling back into the teens overnight. High temperatures on Sunday are expected in the 20s and 30s, and the lows will be in the teens overnight.
On Monday, Feb. 2, the Triangle may again see temperatures rise above freezing.
An extreme cold watch is in effect from late Saturday night through Sunday morning for all of central North Carolina. A cold weather advisory is in effect for the same area from 1 a.m. Saturday until 1 a.m. Sunday. The National Weather Service in Raleigh has also issued a winter weather warning, in effect for parts of the Triangle as early as 4 p.m. Friday and lasting through as late as 1 p.m. Sunday.
Greater impacts expected in coastal NC
Along the coast of North Carolina, snowfall totals may be higher than in central North Carolina, and wind gusts are expected to be stronger.
As of Thursday afternoon, the National Weather Service office in Morehead City said snowfall rates could exceed 1-2 inches per hour during the peak of the storm.
Wind gusts of 55-70 mph or faster are in the forecast for the Outer Banks, and gusts of 40-55 mph are possible inland.
Blizzard conditions are possible over areas such as the Outer Banks. Blizzard conditions indicate sustained winds or frequent gusts to at least 35 mph and considerable falling and/or blowing snow — meaning visibility is frequently reduced to less than a quarter-mile — are expected to continue for at least three hours.
