Lawns are green. Electric bills are dropping. And the temperature gauge hasn't seen 90 all month.

If you're looking for the Ohio River valley's typical sultry summer weather, you're going to have wait.

With winds from the upper Midwest blowing cool Great Lakes air across the bluegrass, July's average temperatures are on track to be among the coolest ever recorded in Louisville, meteorologists said.

With cooler, rainy weather forecasted into the weekend, Louisville is on track to see its first July on record without a day in the 90s. And August may be balmier as well.

That suits bicyclist Anthony Baynard just fine.

"You don't have to worry about that 95 degree heat and humidity. I love it," said Baynard, 62, who rides several miles a day for exercise and to run short errands.

So far July's average high is the coolest on record - 80.7 degrees this month, compared with 1947's record of 82.7 degrees.

With a cold front reaching the area Wednesday morning and rain forecasted through Friday, temperatures aren't expected to top 85 degrees until Saturday, when the calendar switches to August.

"I think we're probably gonna break that record," said Nathan Foster, a meteorologist with the National Weather Service in Louisville.

While residents welcome the more comfortable conditions, utility companies are losing business.

E.ON U.S., the parent company of LG&E and Kentucky Utilities, reported electricity use this July dropped 10 percent from this time last year - enough to power 30,000 homes for a year, spokesman Chip Keeling said. The weather is solely to blame, he said.

Louisville Water Co. reported a 5 percent drop in sales from this time last year. Kelley Dearing Smith, spokeswoman for the water company, said weather is partially responsible, but lagging industrial sales have made a bigger impact.

The cooler weather is proving both a blessing and a curse for gardeners, said Denise Peterson, an urban horticulture agent with the Jefferson County Cooperative Extension. Plants need less watering and perennial flowers bloom longer, but the moist soil welcomes blight and mildew.
