"SAY IT ISN'T SO."
- Hall and Oates
Welcome to Spring Everyone! I have a few things for powderhounds to salivate over, and for Spring-a-lings to boo and hiss. Winter takes a bow and exits stage right on Sunday, but it will be a while before he cleans up his dressing room and leaves the building altogether.
1. WEEKEND WEATHER: Rain arrives late Saturday afternoon from central PA east due to a clipper system cutting through PA and northern Maryland. Though temperatures are in the 50’s daytime, I expect some changeover to snow along the PA/MD border late night, and especially in southcentral and eastern PA. Accumulations would be limited if any due to warm ground surface. Sunday brings clearing and cooler, windy conditions behind the storm, which has the potential to develop once reaching the coast. For northern New England, light snow accumulating perhaps an inch or two at the most, until the secondary develops at the coast.
2. HEY NEW ENGLAND! Keep your eyes on this one. Boston was hinting last night that a turn up the coast overnight Sunday could lead to accumulating snow, especially given an NAO trending toward neutral (means Canadian high pressure block is drifting northeast, allowing coastal storms to nudge farther north). Model variance on this means someone will have to make a call, so I guess it is me. The tightening of the jet gradient in the Northeast and the upper level Low in California will serve to put pressure on the Polar Vortex, causing it to ease north and east into Baffin Bay. I believe this will allow our coastal Low to trek farther up the coast than currently anticipated.
3. SAY IT ISN’T SO. Concern is building for a series of early Spring storms that could deliver wet snow to the I-95 cities on Wednesday and a more significant, plowable snow to the Northeast cities overnight into next Thursday. Following this would be one or more rainstorms on Easter and shortly after to wreak havoc with Sunday worship services and create mud puddles for little children to stomp in wearing their new Easter Sunday dresses. Again, the Boston NWS is already coming out of the gates with indications of an all-snow event. This is usually a sign they believe a southern storm will track along or up the coast. I have a few graphics to explain this and will effort to get them online for you. If I can't, please visit Accuweather to see them.
