...Dry Today, Rain Returns Later Tonight West & Statewide Friday...
...Flood Watch Continues Into This Morning...
...Additional Heavy Rainfall and Thunderstorms This Weekend...
...Renewed Flood And River Flood Expected For Weekend And Into Next Week...

Kentucky got a much needed break from the rainfall today, but unfortunately, another significant round of rainfall is on the way. Widespread light rain is expected to expand across the area starting this evening and into the overnight/tomorrow. Not anticipating additional flooding with this round, but that changes Friday night and Saturday.

Strong southerly flow will transport an abundant amount of moisture into the area starting Friday night. Widespread rains return, but this time, could be moderate to heavy at times. 1 to 2 inches will be possible. Attention then turns to later that evening and overnight where there is the potential for severe weather and more flooding. Some tornadoes and damgaging winds will be possible. All together, 1 to 3+ inches is not out of the question over the next couple days. This rain will cause areal flooding and possibly some flash flooding, while keeping river levels high. Producers should continue to maintain livestock at higher ground!

Dry conditions return Sunday and into the early stages of next work week.

from a morning low of 33 degrees below zero to an afternoon high of 50
degrees above zero. (David Ludlum)
