First Snow in Kentucky

Q: When does it usually first snow in Kentucky?

The median first measurable snow (0.1 inch or more) at Louisville lands around December 7, based on NOAA daily records for the 1991-2020 climate normals period. An early winter brings it by November 12; a slow one holds off until December 28 or later. Other parts of Kentucky differ by weeks, so check the city table on this page.

Q: What counts as the first snow?

These dates track the first MEASURABLE snowfall of the season: at least 0.1 inch accumulating at the station, which is the National Weather Service convention. The first flakes in the air (a trace) usually happen one to three weeks earlier but are not counted, because a trace leaves nothing behind and half of them melt as they land.

Q: When does Kentucky get its first inch of snow?

At Louisville, the median date for the first day with an inch or more of snowfall is around January 7. The gap between first flakes, first measurable snow, and the first real accumulation is the normal rhythm of early winter: the atmosphere flirts before it commits.

Q: What is the earliest it has ever snowed in Kentucky?

Among this page's reference stations, the earliest measurable snow on record is October 19 (1989) at Louisville, when 1.4 inches fell. That is from the station's full NOAA daily record (1948 to 2026); higher elevations in the state have certainly been snowed on earlier than any airport gauge.

Q: Does it snow every year in Kentucky?

At Louisville, yes: measurable snow fell in virtually every winter of the 1991-2020 record. The eastern mountains around Jackson typically beat Louisville by a week. Every corner of Kentucky snows every winter.

Louisville typically sees the season's first measurable snow around December 7. Here is the full window, the rest of the state, and the records.

Flakes, then dustings, then inches

The three first snows of every winter

Every winter actually has three openings, and they are weeks apart. The first flakes come earliest: a trace in the air that melts on contact and never counts in the record books. The first measurable snow, 0.1 inch or more, is what this page tracks and what lands around December 7 at Louisville. The first inch, the one that changes the morning commute, typically waits until around January 7.

The gap exists because early season snow fights a warm ground. The first systems cold enough to snow are usually moisture starved, and the first wet storms are usually a degree or two too warm. When both line up, that is the date neighbors remember.

Where these dates come from

How the Kentucky dates are calculated

NOAA publishes official 1991 to 2020 climate normals for seasonal snowfall totals, but not for first snow dates. The dates here are derived from NOAA's raw daily station records (GHCN-Daily): for each station, the first day of each July to June snow season with at least 0.1 inch of snowfall, across the 30 seasons of 1991-92 through 2020-21, reported as the 10th, 50th, and 90th percentile dates. Winters with gappy reporting are excluded rather than guessed, values that failed NOAA's own quality checks are skipped, and record earliest dates use each station's full period of record from 1872 onward.

Treat the median as a planning anchor, not a promise: any single winter can run two to three weeks either side, and your neighborhood's elevation can move it as much as the calendar does. Once you are inside the window, the 10 day forecast takes over from climatology.

Where do these dates come from?

The underlying observations are NOAA daily station records (GHCN-Daily) plus official 1991-2020 snowfall normals. NOAA does not publish first-snow date normals, so the medians and percentile windows here are derived from the daily records: for each station, the first day of each July-June snow season with 0.1 inch or more, across the 30 seasons of 1991-2020, reported as the 10th, 50th and 90th percentile dates. Seasons with gappy reporting are excluded rather than guessed.
