Area residents may be able to turn off their air conditioners early this week thanks to a strong cool front headed this way.
The cool air will arrive Monday night and last through Wednesday, said Jim Packett, a meteorologist with the National Weather Service in Paducah.
"I'm sure it will be a welcome relief to everyone," he said, adding that the air will also be lower in humidity - around 40 percent, compared to the usual 50 or 60 percent - as the cold front moves through the region.
Packett expects temperatures to drop from the upper 80s during the day Monday to as low as the upper 50s that night. High temperatures during the day Tuesday and Wednesday should be near 76 or 77 degrees. Warmer, more seasonal weather will return later in the week.
The cooler temperatures are due to a northwest flow in the upper atmosphere that will push the cold front across the area. This is rare, Packett said, although this marks the third such "bona fide" cold front this summer.
According to the Associated Press, Typhoon Neoguri altered the path of the North Pacific jet stream, allowing polar air behind a trough of low pressure to spill out of Canada and into the Midwest.
