Philadelphia Week Weather Forecast- Sun PM
The persistant northern jet stream winter trough has built following the exit of our snowstorm yesterday. Cold high pressure will control our weather on Monday and some of Tuesday.
The El-Nino enhanced southern jet is fueling another disturbance that is crossing the country. This area is expected to redevelop as a coastal low near the Delmarva Tuesday night and Wednesday. The GFS model has been consistent in predicting another significant snowfall for Tuesday night into Wednesday. Incredibly, the current QPF predictions for PHL airport is over 1 inch water, or another 12+ inch snowfall by the end of Wednesday! The NAM and NOGAPS model support this storm development, with lower QPF values. Stay tuned!
Solar Climate Discussion (Updated 2/6): This past summer (see post), I suggested that this upcoming winter would be unusually cold due to a prolonged lull in solar activity. The sun is beginning to come out of a solar minimum, and there has finally been the long expected increase in solar activity signaling the real beginning of Solar Cycle 24. There are several sunspot areas, but the solar flux still hasn't taken off. It's still early in the cycle. Total Solar Irradiance continues to be about 1 watt/m2 lower than it was during the peak of the last solar cycle, Solar Cycle 23, in April 2000.
As of early February, it looks like the solar cycle is providing the predicted colder than normal temperatures and the El Nino is providing the potent moisture rich southern jet stream. Continue to expect colder than normal temperatures into the spring.
