A strong cold front moves through Thursday and cold, high pressure builds in for the weekend. While high pressure usually brings fair, sunny skies, this high pressure system will have embedded vorticities (disturbances, or eddy currents) that may bring periods of clouds with the sun.
There’s even a chance of an occasional snow flurry, especially north of the Philadelphia area. Timing of these fast moving vorticities and cloudy periods is too difficult days in advance.
Temperatures will be cold, with highs Saturday near 30 and highs on Sunday nearer 40.
Another strong cold front moves through Tuesday into Wednesday. Light rain possibly changing to snow is possible. Models don’t show low pressure development at this time, but it’s a possibility.
