Another oppressive day ahead

Overnight stays quiet across the Tri-State, with mostly clear skies and temperatures settling into the mid 70s. That calm weather comes as a large area of high pressure in the upper atmosphere remains centered over the Southeast, and sinking air around that system is helping keep us hot.

Friday will be hot and humid again with plenty of sunshine and highs in the mid-90s, with the heat index peaking at 105 degrees. That hot, protective bubble of high pressure will begin to weaken as a disturbance passes through eastern Canada and pushes the hottest air farther south. So that changing pattern brings a slight chance for a shower or thunderstorm on Friday.

Saturday remains hot, with highs the low 90s, but it will not be quite as intense as Friday. Winds gradually turn northerly as a larger dip in the jet-stream pattern develops to our east, allowing somewhat cooler air to begin working into the area. However, that comes with a better chance of scattered showers and thunderstorms during the afternoon, with a lingering chance into Saturday evening. Exactly how much storm activity develops will depend in part on earlier thunderstorms and leftover cloud cover.

There’s good news for Riverfest and the fireworks. A much more comfortable change arrives Sunday, with sunshine and highs in the mid 80s. Sunday night turns mostly clear and cooler, dropping into the low to mid 60s. Labor Day continues the pleasant stretch with sunshine and highs in the upper 80s, followed by another mostly clear night with temperatures in the mid 60s.
