Philadelphia Week Weather Discussion- Tues AM
We had showers and thundershowers develop again late last night. This feature was not predicted by the models. The current anomalously cold and wet weather pattern is not being forecast well by either model. That said, the current forecast is for a similar pattern to what we have had-- high pressure remains to our north, giving us an easterly flow while upper air disturbances in an upper cyclonic flow along with surface lows give us periods of showers and rain. Look for this to continue through Friday with cool temperatures and cloudy, showery conditions. We may have some warm weather for Saturday.
Sat 6/20: A mix of clouds and sun. Chance of showers and thunderstorms. Warm and humid. High 87.
Sun 6/21: Partly sunny/ partly cloudy. High 82.

Solar- Climate Update: 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.
