Unusually cold night could bring frost

Skies will finally clear out Tuesday, and since cold air is still in place, we can expect an unusually cold night.

The coldest nights tend to happen when there are clear skies and calm winds, which will both occur Tuesday night.

The temperatures are cooler than normal for this time of year, which will lead to temperatures near freezing by Wednesday morning. The average latest freeze date for Madison is May 7, so the potential freeze Wednesday isn’t out of line with what is expected this time of year.

A frost advisory is in effect from 1 a.m. to 8 a.m. Wednesday. People should cover any sensitive plants to keep them from being damaged.
