Discussion
Strong high-latitude blocking remains in place to our north and there will be two more storms to deal with in the Mid-Atlantic region over the next week or so. One storm will push towards the North Carolina coastline on Tuesday night and then intensify as it rides up along the coastline on Wednesday. Precipitation is likely to begin in the Philly metro region from this next coastal storm tomorrow evening probably in the form of rain, but then as colder air gets wrapped into the system and “dynamical cooling” develops, the precipitation is likely to change to accumulating snow by early Wednesday and several inches are on the table. Preliminary estimates for the northern and western suburbs of Philly are 3-6 inches with less expected in the city and mainly rain at the southern New Jersey coastline. Looking ahead, yet another storm is likely to impact the region in the Sunday/Monday time frame and this could be a real big one; however, it is way too early to say if this will feature rain or snow. One final note and not what anyone wants to hear, given the possibility of heavy wet snow on Wednesday following some rain at the onset and the expectation for strong wind gusts (though nothing like last storm), the threat for power outages has to be thrown out there once again.
