No changes for the weekend. Both Saturday and Sunday look good weather-wise. It'll be Saturday night that features showers and thunderstorms. Highs should reach near 80 both days. Main focus will be the chance for a few afternoon pop-up showers/storms as cyclonic flow remains in the region with positive vorticity advection. The limiting factor for this will be a lack of moisture to work with.
Monday will be a similar situation to Sunday with the potential for a few showers in the afternoon. A slightly better chance with a few more clouds too, so I'd pick Sunday over Monday for a fair weather day. Monday will also be a few degrees cooler.
Tuesday and Wednesday, a second shortwave moves through with the dynamics for showers, but still a lack of moisture. Some diurnal clouds, but should stay dry.
Thursday through Sunday, we have a shortwave moving through the Great Lakes with surface low pressure developing south of New England. This has the makings for another round of cloudy, damp days.
Overall, perpetual northeast trough remains, and the "Year Without a Summer" continues.
