As of this writing (around 4:15 Wednesday afternoon) the radar is tame, with no showers and thundershowers showing-up. That doesn't mean we will not spy any activity later this afternoon/evening, so keep an eye to the sky.
An approaching frontal boundary helping to trigger any shower activity is the leading edge of some much cooler, drier air which will settle-in to the region tomorrow. Dew points will range in the 50s, with temperatures in the 60s to low 70s (what a difference a day makes!)
The forecast features bright and cool conditions for the next few days through the first part of the weekend; I expect clouds and scattered showers to arrive Sunday, with mostly cloudy conditions and showers expected for Labor Day as well.
