LOUISVILLE, Ky. (WAVE) - Another pleasant night as temperatures drop into the low to mid 60s. High clouds will continue to stream into the area making for a partly cloudy sky at times with patchy fog possible toward morning. I hope you enjoyed the fall preview because the heat wave begins on Monday with highs in the upper 80s to lower 90s. We’ll see a partly cloudy sky during the morning, but become mostly sunny during the afternoon. The hottest day of the week still looks to be Tuesday when mid 90s are likely in the metro. We stay hot through the remainder of the workweek with highs in the low to mid 90s. Not only will the heat increase, but so will the humidity. An isolated shower or storm can’t be ruled out Wednesday and Thursday, but most will stay dry. A cold front pushes into the area late Friday with a slightly better chance of showers and storms, but nothing widespread is expected. Temperatures drop a few degrees by next weekend, but it will still be above average.
