A stationary boundary hangs out across the Commonwealth today while keeping isolated shower and storm chances around. As this boundary wobbles slightly southward, the storm development will be more focused across central and Eastern Kentucky through this afternoon.
A few strong storms are possible with heavy rain, gusty winds, and frequent lightning. Outside of the rain chances, another hot and humid day prevails with highs in the upper 80’s. Heat index values make conditions feel like the mid-upper 90’s this afternoon.
Tonight, any activity should diminish in coverage with the loss of daytime heating. Partly-mostly cloudy conditions take over with mild lows around 70 degrees. Patchy fog likely develops early Thursday morning.
All eyes will then turn towards a potent low pressure system that develops across Western Tennessee. This will pull an impressive slug of moisture into the Commonwealth Thursday as heavy rain and thunderstorms look likely. With an already saturated ground in some areas, additional heavy rain will cause some flooding issues.
As of now, 1-2” area wide is a good bet for Eastern Kentucky, with locally heavier amounts up to 3”+. Rounds of showers and storms will continue into Thursday night and early Friday before a bulk of the precipitation works into the Virginia’s.
Outside of the rain chances, temperatures finally cool off as a break from the heat and humidity occurs. Highs late week drop into the low 80’s with more seasonable temperatures in the mid 80’s this weekend. Spotty showers and storms hang around Saturday through Monday before conditions completely dry out next mid-week.
