Philadelphia Weekend Weather Forecast-Fri PM
Following the frontal passage that occured this evening, we will have an overall dry pattern for both weekend days, but cyclonic flow aloft may result in puffy instability clouds each afternoon. A disturbance appproaching late Sunday may cause showers late in the afternoon.
Sat 6/27: Mostly sunny in the morning, a mix of sun and some clouds in the afternoon. High 85.

Sun 6/28: Mostly sunny. An increase in clouds in the afternoon. High 84.

Solar- Climate Update: We will likely remain in an climatically cool weather pattern for the summer, as solar flux and total solar irradiance are at extreme lows due to an anomalous nadir in the the sunspot cycle. Solar flux is at about 67 (at the height of the sunspot cycle in 2001 and 2002, solar flux values were near 200.) While an increase in solar activity has been predicted to begin, and there are some signs that it has, with such low values, our earth is simply receiving less heat. Additionally, low solar wind values allow higher energy cosmic rays to enter our atmosphere, seeding cloud formation. (Or so the theory goes.) Either way, continue to expect unusually cool weather on average for the next several months, possibly well into the fall and winter.
