Philadelphia Weekend Weather Forecast- Fri PM Update
The forecast has flipped around again, with Sunday being the better of the two weekend days right now. The damp, cooler than normal, unsettled weather of the past week continues into the weekend this time around. The GFS has some showers on Saturday, especially the late afternoon. Sunday should be mostly dry. The easterly wind flow will sock us in. Again, the specifics of this forecast is lower confidence than usual, since the NAM is more optimistic than the GFS for Saturday.
Sat 6/13: Sunny in the morning, becoming mostly cloudy by afternoon. Scattered thundershowers likely, especially during the mid and late afternoon. High 80
Sun 6/14: Mostly cloudy, more bright spots and breaks of sun than Saturday. Cloudiness increases in the later afternoon. High 83

As I've been predicting since last October, we will remain in an climatically cool weather pattern for the end of spring and likely the summer, as solar flux and total solar irradiance are at extreme lows due to an anomalous lull in the the sunspot cycle. Solar flux remains at about 70 (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.
