On the last day of July, it will be warm and humid with a chance of showers and thunderstorms that could bring heavy rain and gusty wind.

It’s the kind of weather that we’ve had all month.

July’s temperatures have averaged about four degrees above average and thunderstorms have dropped nearly a month’s worth of rain in a few hours.

After days of hot and humid weather, a cold front will approach from the west which will allow showers and thunderstorms to develop during this afternoon and into this early this evening.

“Any thunderstorms will be capable of producing locally heavy rainfall, along with strong gusty winds,” the National Weather Service says.

“It will be warm and humid today with temperatures mainly in the middle and upper 80s. The humidity will make it feel like it is in the lower 90s across parts of the region. Any showers and thunderstorms will end from west to east during late this evening and into the overnight.

“Weak high pressure will begin to build just west of the region on Thursday. This will allow slightly less humid air to work in on alight north to northwesterly flow. Temperatures will average closer to normal and it will be a bit more comfortable. The dry weather will continue into Thursday night and Friday with seasonable temperatures.”
