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.

Kentucky schools usually close around 2 inches of overnight snow. Hilly rural bus routes mean 2 inches or any ice closes many counties; NTI days cover the rest. The meter below opens on Louisville; type your ZIP or town and it reads tonight's hourly forecast for your exact spot and scores it against the Kentucky threshold.

How much snow it takes in Kentucky

Kentucky's snow problem is its roads, not its totals. Louisville averages 13.4 inches a season and 1.1 days with 3 inches or more, Lexington 14.5 inches, and Northern Kentucky at the Cincinnati airport 23.3. January is the snowiest month. But most of the state's 171 districts are counties, and a county bus route in eastern Kentucky climbs hollows and ridge roads that no plow reaches before 6 am. Two inches, or any ice, is enough there, which is where the model's 2-inch threshold comes from.

Kentucky also invented the modern remote snow day. Non-Traditional Instruction, NTI, began as a pilot in 2011 and went statewide in 2014-15, and most closures now arrive as NTI days rather than cancellations. Jefferson County Public Schools in Louisville called one for inclement weather on 2 December 2025 and another on 15 December 2025 for forecast frigid temperatures before dawn.

The state cabinet fields more than 1,400 plow trucks and 369,000 tons of salt across all 120 counties, but the school buses are on the county and private roads behind the state routes.

How closures are decided in Kentucky

Kentucky requires 1,062 instructional hours and 170 student attendance days (KRS 158.070), the fewest days of any state with a day count except Minnesota. Against that, the commissioner of education may grant a district with an approved nontraditional instruction plan up to the equivalent of ten student attendance days for days the district is closed for health or safety reasons. The plan must show how NTI continues the learning of regular attendance days and spell out how instruction is delivered. The programme ran without a limit during the pandemic and reverted to the statutory ten in autumn 2021.

Beyond ten NTI days the days must be made up, and in bad winters the legislature has considered relief: a 2026 bill as introduced would have waived up to five attendance days for 2025-26 and allowed make-up by lengthening the school day; we did not find whether it passed. We could not read the statute text itself, which was blocked, and we did not find a state rule naming who decides a closure; in practice it is the county superintendent.

Questions people ask

What is an NTI day in Kentucky?
A Non-Traditional Instruction day: the district is closed for weather or another health or safety reason but teaches remotely under a plan approved by the commissioner of education, and the day counts as one of the 170. A district may use up to ten a year.
Does Kentucky still have real snow days?
Fewer every year. Most districts call an NTI day first and keep plain cancellations for when power or internet is out, or once the ten NTI days are used. The meter scores the chance that buildings close; whether the day is NTI or a cancellation is the district's choice.
Why do Kentucky counties close on 2 inches?
Because the buses run hollows and ridge roads that are not plowed by bus time, and because an inch of sleet on a grade is worse than 4 inches of powder on flat ground. Louisville averages 1.1 days a year with 3 inches or more, so even the cities are not practised at it.
What happens after ten NTI days?
The remaining missed days must be made up to reach 170 attendance days and 1,062 hours. In hard winters the legislature has considered waiving some days and allowing longer school days instead, as a 2026 bill proposed; check your district's calendar notes for the current year.
