Excessive Heat Watch for all of Kentuckiana from Thursday afternoon through Sunday evening
The rain gear may come in handy again today as the remnant low associated with Barry continues to make its way through the Ohio Valley. While the showers and thunderstorms may not be widespread, give the tropical moisture around anything that develops has the potential to produce some localized heavy rain. Even with the clouds and showers around, afternoon highs will be topping out into the upper 80s to near 90 degrees along with the humid conditions persisting. As the system begins to work out of the area Thursday, a spotty shower can’t be ruled out, but many spots will remain dry with highs climbing back into the low 90s. This will be a prelude of things to come into the weekend.
Once again, a big bubble of heat and humidity will take hold of a good chunk of the central and eastern part of the country late this week and through the upcoming weekend. Afternoon highs will be in the low and even mid-90s, especially here in Louisville metro. Factoring in the high humidity levels that are expected and our heat indices should top the 100-degree mark in many locations. As a result, an Excessive Heat Watch is out for all of Kentuckiana Thursday through Sunday. If you have outdoor plans this weekend, try to avoid any strenuous activity during the hottest part of the day. The only relief could be a widely scattered storm during the afternoon, but most spots will stay dry. A cold front will increase storm chances Monday, followed by cooler and less humid air into Tuesday.
TODAY: Breezy with more scattered showers and storms. High: 90. Wind: W 10-15 mph.
TONIGHT: Warm and humid, isolated showers. Low: 76. Wind: SW 5-10 mph.
THURSDAY: Hot and humid with a few pop-up storms possible. High: 94. Heat index 100°+. Wind: S 5-10 mph.
