Best time to check

The evening before, after 9 pm
The evening model runs are in by then and the forecast here refreshes every 30 minutes. A number read at 6 pm can move by several inches of snow before midnight.
The morning of, 5 to 7 am
The strip above shades 4 to 7 am. Snow still falling in those hours lands on the commute, so the model counts it extra, and most districts have decided by the time the buses roll at 7.

When districts actually decide

Every district sets its own cut-off; these are published examples, not a rule.

North Carolina schools usually close around 1.5 inches of overnight snow. Charlotte and Raleigh close on an inch or on ice; the mountains at more. The meter below opens on Charlotte; type your ZIP or town and it reads tonight's hourly forecast for your exact spot and scores it against the North Carolina threshold.

How much snow it takes in North Carolina

Charlotte and Raleigh close on an inch or on ice; the mountains at more. Charlotte averages 3.5 inches a season and one day a year with an inch or more; Raleigh 5.2 inches and 1.5 such days; Greensboro 7.1; Asheville, up in the Blue Ridge, 10.3 inches and 1.1 days with 3 inches or more. January is the snowiest month everywhere. The model's 1.5-inch threshold is the Piedmont number, and the freezing-rain term is what usually carries a North Carolina forecast over the line.

The 2026 winter showed the modern North Carolina pattern, which is a split between closing and going remote. Charlotte-Mecklenburg Schools went remote on 27 January for winter weather across the county; after the 31 January snowstorm the district closed outright on the Tuesday while Cabarrus, Gaston, Iredell-Statesville and Catawba went remote. Which one a district picks depends on how many remote days it has left.

1991-2020 climate normals for the airport or first-order station in each city, read 2026-10-10 from the NOAA NCEI U.S. Climate Normals. “Days with 3″+” is the average number of calendar days a year with at least 3 inches of new snow.

How closures are decided in North Carolina

North Carolina sets the calendar at 185 days or 1,025 hours, per the Education Commission of the States' 2023 survey; the statute itself, G.S. 115C-84.2, was not reachable when we checked, so we cite the survey. Remote instruction may not be used to meet that minimum except within the allowance in G.S. 115C-84.3, enacted in 2021: a public school unit may use up to five remote instruction days or 30 hours a year when schools cannot open for severe weather, energy shortages, power failures or other emergencies, and a unit in a county holding a good-cause calendar waiver may use up to 15 days or 90 hours. A governing board that wants to use them files a remote instruction plan with the State Board by 1 July each year.

Remote instruction here means instruction delivered outside the school facility, synchronous or asynchronous; homebound, virtual public school and suspension instruction do not count against the allowance. Beyond the allowance a closure is a closure to be made up. We did not find a state rule on who decides, and the Department of Transportation's pages were blocked; the 121 county and city districts make their own calls.

Questions people ask

How many remote days can a North Carolina district use for snow?
Five days or 30 hours a year for most districts, and 15 days or 90 hours for units in counties with a good-cause calendar waiver, under G.S. 115C-84.3. Once those are used, a weather closure has to be made up in person.
Why did Charlotte close while its neighbours went remote in February 2026?
Each district spends its remote allowance differently. After the 31 January 2026 snowstorm Charlotte-Mecklenburg closed on the Tuesday while Cabarrus, Gaston, Iredell-Statesville and Catawba went remote. The meter predicts whether buildings close; the remote-or-closed choice is the district's.
Does Raleigh close for an inch of snow?
Usually, and for a glaze of ice more surely still. Raleigh averages 1.5 days a year with an inch or more and 0.5 days with 3 inches or more, so neither the roads nor the drivers are practised. The meter weighs freezing rain hours and any Winter Storm Warning on top of the total.
Is the mountain threshold the same as the Piedmont's?
The model uses one statewide threshold of 1.5 inches, which overstates the chance in Asheville and the high counties that see 10 inches a season and plow routinely. Read the reasons under the number for a mountain ZIP; a Winter Storm Warning there matters more than the first inch.

The closure threshold itself is our model's estimate from typical district practice, not an official figure. Districts, not states, make the call. The model page shows every term.
