LABOR DAY WEEKEND Weather

While the calendar says fall begins around September 21 each year, many people consider Labor Day weekend to be the unofficial end of summer. By convention, meteorological summer is defined as the whole months of June, July, and August.

The sun is strongest at the summer solstice in late June. Since there is a time lag between the strength of the sun and the seasonal temperature curve, the warmest days of the year occur weeks after the summer solstice.

When are the warmest months of the year? At Paducah, normal daily highs reach 83 degrees on June 1 and fall below 83 degrees on September 15. Of course, weather is rarely normal. Looking at past Labor Day weekends so far this century, here are what daily temperatures looked like for each 3-day weekend at Paducah:
