...Sunny And Dry Into The Weekend; Patchy Frost Again Tonight...

Temperatures have risen into the middle 50s to low 60s as of 2PM. Look for those readings to rise a bit further before falling back into the 30s overnight. Saying that, temperatures will be warmer than this morning and keep frost patchy in nature, mainly across Eastern Kentucky. The good news is that after tonight, freezing temperatures or frost is not expected over the upcoming week.

Looking at frost/freeze occurence data, most of Kentucky has passed the average last freeze date for spring.

The dry weather with slightly below normal temperatures will continue through most of the the weekend. Better rain chances return later on Sunday across Southern Kentucky and expands northward into the early start of the work week.

Weather History...

A spring storm produced unusally heavy snow in northeast Ohio. Warren
received 35.5 inches in thirty-six hours, and 28 inches fell at Green Hill.
Akron OH established April records of 15.6 inches in 24 hours, and 26.6
inches for the month. Pittsburgh PA established April records of 12.7
inches in 24 hours, and 13.5 inches for the month. (David Ludlum) (The
Weather Channel)
Tornadoes in Mississippi and Alabama killed 219 persons. (David Ludlum)
An unseasonably warm and moist air mass had settled across eastern Kentucky 
leading to record breaking temperatures at the Jackson Weather Office and the 
London Corbin Airport between the 16th and 21st of April. Jackson saw several 
days in a row with record high temperatures as well as maximum low records. On 
the 19th the mercury soared to a record high of 89 degrees at Jackson and a 
record tying 87 degrees at London. The low temperature at Jackson was a balmy 69 
degrees good enough for a daily as well as a monthly maximum low temperature 
record. (NWS Jackson)
