The long duration major winter storm that has impacted the Mid-Atlantic region since Sunday will continue to produce occasional snow here today and tonight and winds will remain quite strong. The occasional snow can result in additional small accumulations for the region adding on to the prior hefty two-day totals (e.g., 12+ inches in King of Prussia, PA). High pressure will edge into the region on Wednesday and it’ll stick around on Thursday. A frontal system will cross the area on Friday and it could generate some rain and snow showers in the Mid-Atlantic region. One final note, Phil sees his shadow…6 more weeks of winter...very smart rodent.

Low pressure continues to deepen off the Mid-Atlantic coastline and it will continue to have a major impact on the northern Mid-Atlantic through tonight in the area from eastern PA-to-New Jersey-to-southeastern New York. Mixed precipitation this morning has changed to snow in most places as colder air wraps into the system from the north/northeast. There will continue to be small-scale bands of very heavy snowfall from later today through tonight and many spots will end up with 1-2 feet of accumulation from this long duration storm system by the time it winds down later Tuesday.

Low pressure will intensify off the Mid-Atlantic coastline today and push very slowly to the north as it encounters a blocking pattern in the atmosphere. The brunt of this winter storm will take place from later today into tonight as heavier rounds of precipitation work their way across eastern Pennsylvania and the winds will pick up in intensity as well. Any mixed precipitation this morning should change back to all snow by late morning or mid-day as colder air wraps around the intensifying storm off the Mid-Atlantic coastline and significant additional accumulations are likely. Given very strong dynamics in the upper atmosphere, there is the potential for “mesoscale” or small-scale banding later today and tonight containing brief outbursts of very heavy snow and possible rumbles of thunder. Total snow accumulations from this storm by later tomorrow can surpass a foot in the Philly metro region.

A major and complex storm system is coming to the Mid-Atlantic region and it will be a long duration event with impact into Tuesday. Indeed, this storm could turn out to be one of the all-time greats for some sections of eastern PA, upstate New Jersey, and southeastern New York. The storm will come in two phases with the first part already underway and associated with a process known as “overrunning”. The second phase of this major winter storm event will feature a very slow moving and powerful storm just off the Mid-Atlantic coastline.

The stage is set…Arctic air is in place anchored by strong high pressure to the north and a major and complex storm system is coming to the Mid-Atlantic region and it will be a long duration event with impact from Sunday into Tuesday. Accumulations of 6+ inches are possible in the DC metro region with 12+ inches possible in the Philly and NYC metro areas. The storm will come in two phases with the first part associated with a process called “overrunning” and the second phase featuring a major coastal storm. The combination of the potential heavy snow and strong winds may prompt the need for “blizzard warnings” to be issued in at least parts of the Mid-Atlantic region for this upcoming event.
