As always another tough call for our area with a second coastal storm in 5 days only this time around there are some important differences. The National Weather Service snow forecast maps are up and updated as amounts are raised across most areas including coastal areas around Long Island. Winter Storm Watches are extended further south in New Jersey down to Route 195 as well as southwestern New Jersey. The coastal counties from Ocean county southward are not under a watch at this time. The Winter Storm Watch is also extended across all of Eastern Pennsylvania as far west as Harrisburg as well as 2 counties in Northeastern Maryland. The afternoon NAM model has picked up on a colder slightly more east idea with the developing noreaster.
This is the late afternoon NAM model showing positive snow growth. What this means as that the model takes into account any sleet, rain or melting. Notice that it gives a range of about 2 to 6 inches across the area. However if this falls as all snow and that is entirely possible amounts would be easily.
