The low pressure system that has been held over us by a blocking pattern will move away, allowing high pressure to bring better conditions to our area.
On Saturday, an upper air disturbance still associated with that low may rotate through, bringing mid-level cloudiness (altocumulus) in the late morning and early afternoon. Some clearing late afternoon. High on Saturday still cold at 39.
On Sunday, high pressure will build in for mostly sunny skies. Temperatures finally moderating with a high of 48.
This afternoon’s models have greatly diminished the chances of any accumulating snow Tuesday night. In fact, they have backed away from the high rain amounts, with the heaviest rain now tapering in the afternoon.
This is a very dynamic system and I expect further changes in the forecast.
Latest NAM cranks out several inches of snow by Wednesday morning (4 inches) as the heavy rain Tuesday transitions to snow Tuesday night. This is for PHL airport. More north and west.
The predicted thermal profile of this storm continues to become colder as it moves slowly past us Tuesday night. Stay tuned.
