Frost threat tonight

Good Sunday and Happy Mother’s Day. To celebrate the big day, Mother Nature is taking center stage and not for the best of reasons. A very chilly air mass continues to filter into our part of the world and this will set us up for a frost threat tonight into Monday morning.

The good news is that some sunshine will be noted out there today. We wills tart thermometers out in the upper 30s to low 40s and end things with temps in the high 50s. That’s close to 15 degrees below normal.

Temps tonight will drop into the low to mid 30s and this will set the stage for frost across much of central and eastern Kentucky. Record lows may also bite the dust:

Lexington: 37 1996     32 is the coldest recorded temp for this late in the season. (May 20, 1894)

Frankfort: 34 1941     31 is the coldest recorded temp for this late in the season. (May 22, 2002)

We have a shot at getting close to the coldest readings we’ve ever had for this late in the spring. Any fog or high clouds will have an impact on thermometers and how low they can go.

Temps by Monday afternoon will be near 60 degrees with more sun. Much warmer air will start to push in by Tuesday and that really kicks into high gear for Wednesday:

This is the start of a more typical May setup that will also lead to more in the way of showers and thunderstorms:
