If you're planning to do something outside today, it will be hot and humid with limited storm chances. Big changes this weekend?

This Morning:
Mostly sunny, warm and muggy
Temperatures: 70s
Wind: S 5-10 mph
This Afternoon:
Partly to mostly sunny, hot and humid. Isolated t'storm possible west of the Blue Ridge
Highs: Around 90 degrees
Wind: SSW 5-15 mph
A few clouds, warm and muggy
Lows: Middle 70s
Wind: S 5-10 mph

Our weather pattern remains fairly similar to that of our 4th of July with hot and humid conditions and only isolated chances of showers and thunderstorms. A ridge of high pressure off the coast will keep us under mostly sunny skies today with a nice south southwesterly breeze. High temperatures will once again climb into the upper 80s to lower 90s, but remember, with the high humidity it will feel closer to the middle and upper 90s. Clouds and showers through the Ohio and Tennessee river valleys today, as that steady stream of moisture (that we endured earlier this week) slides north from the Gulf of Mexico. The more likely chances for any afternoon thunderstorms today will be well west of Washington, mainly west of the Blue Ridge.

This weather pattern sticks with us through the first half of the weekend. By Sunday, an upper level low develops over MO and tracks northeast around the ridge. That means a few more clouds by Sunday and, also, a slightly greater risk for showers and thunderstorms. It won't be a washout, by any means, but you'll want to keep an eye to the sky for developing storms.

Kicking off the next work week, high temperatures will remain in the lower 90s with typical late day chances for showers and thunderstorms each day. A few weak weather fronts will slide through keeping storm chances around 40% through the week.
