Discussion
Low pressure will develop intensify today as it rides up along the east coast to a position near the central New Jersey coastline by later in the day. Enough warm air will come in from off the ocean to keep the precipitation as a mixture for awhile near Philly, but the dominant precipitation type in the northern and western suburbs will be snow. In fact, small-scale heavy snow bands may form across eastern PA and New Jersey later today as intense “frontogenesis” takes place in the atmosphere. These snow bands can result in a couple inches of snow per hour and “thunder snow” is also a possibility. Given the nature of the snow (i.e., heavy and wet) and the fact that there was rain at the onset, power outages will be a concern today in the entire I-95 corridor. The snow winds down this evening and then we’ll have colder-than-normal weather for the latter part of the week. Another storm threatens for Sunday/Monday.
