Why does Portland close for 2 inches?

Hills, buses and ice. Portland averages 0.5 days a year with 3 inches or more, so nothing is set up for it, and the Gorge east wind often turns the snow to freezing rain on the west side. The January 2024 ice storms closed Portland and Beaverton schools for two days with little snow at all.

Do Oregon schools make up snow days?

The hours have to be met, and since the governor's April 2026 executive order the state will not waive them except in a declared emergency. Portland Public Schools plans up to three snow days made up on 16, 17 and 18 June, then remote learning days that need no make-up.

Is there a statewide remote snow day rule in Oregon?

Not that we could find. The remote days Portland and other districts use are district plans under the hours rule, not a named state programme, so check your own district's calendar page.

What about east of the Cascades?

Pendleton averages 15.7 inches a season and 4.8 days with an inch or more, and Bend and the mountain districts see more, so the model's 2-inch statewide threshold overstates the chance there. Read the reasons under the number; a Winter Storm Warning or drifting on county roads matters more than the first 2 inches.

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

Portland Public Schools, Oregon publishes its closure decision no later than 5 am (read 10 Oct 2026)
Omaha Public Schools announced the 23 January 2026 cold closure at 5:50 pm the evening before (read 10 Oct 2026)
Little Rock School District announced a two-day closure the afternoon before the 9 January 2025 storm (read 10 Oct 2026)
Minnesota e-learning days must be announced at least two hours before the normal start time, by statute (read 10 Oct 2026)

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

Oregon schools usually close around 2 inches of overnight snow. Portland closes on 2 inches or freezing rain; the east side and Cascades tolerate more. The meter below opens on Portland; type your ZIP or town and it reads tonight's hourly forecast for your exact spot and scores it against the Oregon threshold.

How much snow it takes in Oregon

Portland closes on 2 inches or on freezing rain, and the state's geography explains both. Portland International averages 4.2 inches of snow a season, 1.4 days with an inch or more and 0.5 days with 3 inches or more; Pendleton, east of the Cascades, averages 15.7 inches and plows through it. The Willamette Valley's winter problem is the Columbia Gorge: east wind pours cold air under Pacific rain and the valley gets a glaze rather than a snowfall.

That is what closed Portland Public Schools and Beaverton for two days on 16 and 17 January 2024, after holiday-weekend ice storms left power outages and storm damage. The model's 2-inch threshold carries the Portland metro; the freezing-rain term carries the rest. Oregon uses salt sparingly, about 7,600 tons a year statewide against 4.2 million gallons of liquid de-icer, which keeps side streets slick longer than in a salt state.

Portland Public Schools publishes its plan each year: decisions by 5 am, up to three snow days made up in mid-June, and remote learning days after that.

Oregon winter by the numbers

Station	Snow per season	Days with 1″+	Days with 3″+	Snowiest month
Portland	4.2″	1.4	0.5	Jan
Pendleton	15.7″	4.8	1.4	Dec

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. NOAA publishes no 1991-2020 snowfall normal for Eugene.

How closures are decided in Oregon

Oregon's year is written in hours: 900 for kindergarten through grade 8, 990 for grades 9 to 11 and 966 for grade 12 (OAR 581-022-2320), and a district must schedule at least 92 percent of its students district-wide and 80 percent at each school to reach them. The rule text we read allowed up to 14 hours of adverse-weather closures to count with board approval, but only for the 2015-16 school year; we did not find a current standing weather allowance, so we do not state one.

The state tightened in 2026. Executive Order 26-06 of 16 April 2026 bars the Department of Education from granting or renewing waivers below the minimum hours except in declared emergencies, and the State Board issued temporary rules to match. There is no state virtual snow day programme that we could find; Portland Public Schools' switch to remote learning days after three snow days is a district plan. Oregon's 175 regular districts decide their own closures.

Minimum school year: 900 K-8, 990 grades 9-11, 966 grade 12 hours (OAR 581-022-2320)
Waivers: Barred except for declared emergencies since Executive Order 26-06, 16 Apr 2026
Remote snow days: No state programme found; Portland Public Schools uses them after 3 snow days
Regular districts: 175 (NCES, 2021-22)
