Temperatures are expected to drop in the low 20s today and Wednesday, according to the National Weather Service in Paducah.
The weather service predicts today's high will be 40 degrees with a low of 21. On Wednesday, the high will be 43 with a low of 25. The cold air comes on the heels of the region getting a rare snowfall Monday morning-- eight-tenths of an inch, according to the NWS.
Meteorologist Mike York said this week's freeze could do some damage to plants, particularly ones that have bloomed during the unusually warm winter.
Temperatures will rise toward the end of the week, reaching close to 50 Thursday and 60 on Friday.
There could also be some rain and thunderstorms by Friday, though York said they aren't expected to be severe.
