Remarkably cold air for this late in the season comes rushing in on the heels of today's steady rain. Temperatures will plummet into the mid to upper 20s once the showers end, clouds break, and the wind backs off. This air mass is coming straight off of the polar express. This level of cold could not only break the daily record low, but also challenge Lexington's all-time coldest May temperature.
There are some limiting factors that may lead to not as cold of temperatures overnight - fog development and a lingering stiff breeze. However, even temperatures around freezing will do damage this late in the season. A Freeze Warning will be in effect overnight. This will be a widespread damaging freeze. Plants, flowers, crops, and tender vegetation will need to be protected.
