It's hard to believe that it was 99 degrees just a little over a week ago. A Frost Advisory has been issued for all of the counties west and south of Louisville. The urban heat island in the city will keep us well above freezing tonight so no frost at my house. I can't remember the last year we had cold temperatures like this, so early in the year. Last year, we didn't get our first freeze of the year till the first week of December.
