Heat Continues, Humidity Rising, Fireworks Forecast

Wednesday, July 4th, 2012 – Independence Day: Heat Continues, Humidity Builds… Fireworks Forecast

Good Wednesday morning, folks, and HAPPY INDEPENDENCE DAY!  It’s the blockbuster summer holiday, and we’re still dealing with a classic, big-time, midsummer heat wave.

Yesterday’s highs were in the middle 90s across most of central Kentucky.  In Lexington, the heat was significant, but not at the record standard of 98° from 1911 (which happens to also be today’s record high, also from 1911).  However, in eastern Kentucky where the records don’t go far back enough to include the hot stretches of 100 years ago, we were warm enough to tie a record in London.  In Jackson, where the books only go back to 1981, we set a record high.  Huntington, WV sailed all the way up to 97 degrees, tieing their record high from 1898, and most recently (before yesterday) tied in 1911.

Today will be another very hot one, with highs near 96° in Lexington.  By the numbers, the next few days will feature highs in the upper 90s, which is not quite as hot as last weekend.  However, humidity levels will be rising, and this will boost the heat index above 100° during the hottest part of the next few afternoons.  The farther west you are, the hotter it will be, with heat indices in the 105° to 110° ballpark during the next few afternoons to our west.

In light of this, Heat Advisories are in effect across central and northeastern Kentucky, as well as the interior part of eastern Kentucky and the Lake Cumberland region.  An Excessive Heat Warning is in effect for Owen, Grant, Pendleton, Henry, Shelby, Spencer and Nelson Counties, and westward.  These heat alerts will remain in effect through the end of the week.

After today’s high near 96°, the evening will be very warm and muggy.  Like the past few days, there will be some isolated, hit-or-miss thunderstorms, but coverage will be fairly slim.  Temperatures will fall very slowly tonight, with readings near 90° as many folks head out, but after the fireworks, we should be cooling through the middle and eventually lower 80s.  It will be muggy, though.

Be careful as you celebrate, especially with all of the recent dry weather in mind.  Despite the isolated t-storm that impacted parts of Fayette County yesterday, the civilian use of fireworks remains banned today in Lexington.

Happy 4th!
