Frost expected Friday and Saturday. Highs back to normal for remainder of week.


-Chance of precipitation Thursday

-Much cooler temperatures expected Friday and Saturday morning

-Highs returning to average

Skies will be mostly cloudy to overcast for the duration of the night and morning as light to moderate showers continue to develop on radar across the western portion of Kentucky.   Light showers are not out of the question for us as well for the duration of the day on Thursday as the closed low pressure system that has been located across the plains quickly traverses eastward and is once again re-absorbed into the general flow, but any precipitation we receive should accumulate to less than a tenth of an inch.    Highs look to be much cooler than as of late only reaching the mid 60’s Thursday under the influence of the cold core 500mb low pressure system and overcast skies, with lows in the mid 50’s Thursday morning and falling to the upper 40’s around the midnight hour.  Things get really interesting during the overnight hours Friday.  As the closed low pressure system is absorbed within a trough swinging through the eastern half of the United States, it starts to deepen and strengthen.  As this occurs, our placement in relation to the trough will allow cold air from Canada to pool into the Kentucky region as well as the eastern half of the United States.

500mb projected heights and winds for Friday at 12Z. This setup will send cold air from Canada down south into our region

Temperatures don’t look to reach the freezing mark, but frost will still be a likely occurrence under the presence of clear skies with light winds and the temperature approaching the dew point.  The low Friday morning looks to be a chilly start to the day in the mid 30’s and clear skies for the duration of the day, but temperatures will rebound back into the mid 60’s for the high.  Saturday looks to bring little change from Friday with highs still in the mid 60’s and lows in the upper 30’s.  Frost is also a possibility Saturday morning with skies continuing to be clear, light wind speeds, and the temperature once again approaching the dew point.  The low Sunday morning should be much warmer because the upper level trough is forecasted to have sufficiently traversed to the east away from Kentucky.   Lows look to be in the upper 40’s, with highs approaching the upper 60’s mark Sunday.
