Several locations around the area are highly likely to have set new records for May 17.
The record low maximum temperature for Louisville for that date was 58 degrees, set in 1915.
Likewise, the record low maximum for Lexington was also 58, set in 1915 and 1895.
Finally, the record low maximum temperature for Frankfort for the date was 58, set in 1978.
These unusually cool temperatures and dreary, wet conditions are courtesy of a pair of upper lows spinning over the Tennessee Valley and Appalachians. The 500mb heights below depict these upper lows beginning to merge over the region as seen by the animation of the light blue lines. Also, the blue and white colors on the water vapor imagery depict atmospheric moisture being pushed westward into our area from the Atlantic Ocean. As these upper lows merge into one upper low which will continue to meander across the region through Thursday, cool and wet conditions will prevail.
