The morning will start with sunshine and patchy dense fog as temperatures again will be warm and muggy. The rest of the day will stay dry with highs dropping slightly into the mid to upper 80s. A weak frontal system has managed to just suppress the heat and humidity for a day. Back into Friday, we'll see more humidity and a rather standard August 30% chance for afternoon rain/storms.
The Labor Day weekend will stay mostly dry with Sunday the only day for likely scattered rain. Another frontal boundary will attempt to push through the Tri-State without any luck.
When the rainmaker comes close, from early to midday Sunday, we'll see scattered rain and a chance for storms. During the day Sunday, we are running at a 50% chance for wet weather with the chances dropping to 30% by the early evening. As of now, the fireworks forecast looks okay for Riverfest.
The final word is this...the type weather systems that will approach the Tri-State can pose timing issues. So, don't cancel any plans.
Patchy dense fog
Not as hot
