Whether you like it or not, the time has come for the first snow of the season. An Arctic system will bring a brief period of rain, which changes over to snow Monday evening as temperature sharply drop. Light accumulations are possible by Tuesday morning, but it will be mostly on the grass.

Here's the timeline. Rain showers will develop after lunchtime behind a strong Arctic front. Temperatures will fall quickly, and by the evening rain will have changed to snow across central Kentucky. Snow will continue to fall through early Tuesday morning. Flurries will linger through late Tuesday, but the accumulating snow will have wrapped up.

The snow will have to overcome warm ground temperatures to start sticking. Given the warm road temperatures, we aren't expecting too many issues on the roads. However, some slick spots may develop as patches of melted snow freeze due to the dropping temperatures. Snow will more readily accumulate on the grass and elevated surfaces, like bridges and overpasses. A coating to an inch of snow is possible for central Kentucky; up to 1.5" will be possible across the ridges of southeastern Kentucky.

Our first snow of the season is coming right on schedule. Lexington's average first trace occurs right around this time. The first measurable snow usually comes by the end of November. Meanwhile the first inch of snow doesn't fall until mid-December.
