Winter Storm Warnings Mid Atlantic to New England, Coastal Flooding Strong Winds
Winter Storm Warnings have been now issued for the few remaining counties in Northern New Jersey, NYC, the Lower Hudson Valley, Southern Connecticut and Long Island. Winter Storm Warnings continue for New Jersey, much of Pennsylvania, much of Delaware, Maryland, Virginia and Northern and Western North Carolina. Winter Storm Watch continues for the rest of Southern and Central New England as well as the Middle and Upper Hudson Valley. Warnings will likely be issued there later today.
Coastal Flood Warnings are in effect for the Delaware, New Jersey and Long Island shore lines. Moderate to major coastal flooding is forecast for these areas with up to 3 feet of tidal inundation. Winds are going to be a big deal to and increase to 40 to 50 mph in gusts from the northeast along coastal areas.
National Weather Service snow forecast estimates have been raised. This is a two day event with snow lasting in some areas until Tuesday evening before it finally ends. There will be the first solid push of snow ahead of the developing low tonight into Monday night. Then we will deal with the backside issues of the upper air system that will be to our east.
Clouds increased quickly overnight the radars are blossoming out with snow especially the Mid Atlantic regional radar which is loaded with snow and it is pushing it up to the northeast. Expect snow to spread into Southern Pennsylvania and Southern New Jersey today and to points further north tonight.
There really isn’t much change in how this all plays out. Low pressure in the Ohio Valley dies out. The secondary takes over near coastal North Carolina and heads for a point east of Delaware and south of Long Island. That low center basically meanders around as there is no system upstream to move it along.
This loop takes us from 11am today until 1pm Monday. At this point heavy snow is falling from New Jersey to Long Island and New England. A change to rain is forecast for parts of Coastal and South Jersey in the afternoon. A change to sleet and rain is possible for Central and Eastern Long Island Monday evening for a few hours. All areas should change back to snow later Monday night into Tuesday.
Eventually the storm does move out of the way later Tuesday and Tuesday night. Everything winds up by Tuesday evening and then we move on to improving weather conditions for Wednesday into Thursday. As for my snow amounts I have raised them somewhat by a couple of inches and below forecast model snow amount forecasts.
Unless there is a radical change we don’t expect to change much from these numbers. We remain watchful regarding the possibility of some upside surprises showing up in some places. That possibility certainly exists especially near areas that are close to a transition line from snow to rain.
