Philadelphia Weekend Weather Outlook- Wed PM
We will get a short spell of summer weather for the next two days, before another frontal boundary moves through Friday night. The latest GFS models show another closed low developing off the coastline as an unstable upper air cooler cyclonic flow will be with us again over the weekend. A few days ago, I thought we might be finally escaping this terribly un-summerlike pattern, but it appears that the weekend may become unsettled again with a mix of clouds and sun, somewhat cooler than average temps and several chances for showers. Exact timing of the showers will make or break this weekend.
Overall, the weekend looks mostly dry and will not be any sort of rainout (at least it seems that way now), but a slight shift in pattern or timing of showers might make things much less ideal than we all would like.
Sat 6/27: A mix of sun and clouds, more sun than clouds. A chance of a shower or thunderstorm in the afternoon. High 84

Sun 6/28: Mostly sunny in the morning, then increasing clouds with a chance of shwoers in the afternoon. High 81

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.
