Summer unofficially ends very summer-like. The Labor Day forecast will be very warm and muggy with highs in the upper 80s to near 90°. The combination of some afternoon clearing and a weak frontal boundary could spark isolated storms. Keep an eye to the sky if you have a "goodbye to summer" pool party or cookout planned. Any storms that do bubble up with fizzle during the evening. High pressure will keep things toasty and dry through mid-week.
A relatively dry cold front will will follow up the hot and dry start to the week. There will be isolated storm chances again, especially across southeastern Kentucky, as the boundary treks through the Bluegrass on Wednesday. Then say hello to fall! High temperatures will drop from near 90° to the upper 70s by late week. We'll keep the cooler and less humid conditions going into next weekend.
Meanwhile the big national weather headlines remains Hurricane Dorian. The storm barreled through the northern Bahamas today as a catastrophic Category 5 storm. Dorian is expected to drift towards Florida's Atlantic coast on Labor Day. The severity of the impacts will be determined by how far west the center of the storm tracks. A farther west track will put more areas in a possibly dangerous situation. Tropical force- to hurricane-force winds along with very heavy rain, storm surge, and rip currents will be possible through mid-week as Dorian jogs northward. Coastal areas of Georgia, the Carolinas, and possibly parts of the Mid-Atlantic will also feel the brunt of the storm through late-week.
