The latest models suggest less low pressure development and less certainty about Sunday’s snow forecast. Certainly appears to be a less impressive storm.
So, once again this season, the Philadelphia area appears to escape from a potential storm. Some light snow still a possibility.
Possibly two centers of low pressure are expected to develop along a frontal boundary moving through our area later Sunday. The statistical models are highly scattered with the position of the low centers, but the latest GFS has the rain-snow line moving west to east during Sunday evening and early Monday.
A complex snow -> rain -> snow transition is possible with this storm. QPF values over 1 inch water are predicted by the NBM, suggesting a possible significant snowfall, particularly areas west of I-95.
Below average confidence at this time, but things should come into focus over the next day or so. Stay tuned.
