4th Nor’easter of the Month Set for Wednesday PM

You’re tired of it, I’m tired of it, we’re all tired of it.  That doesn’t matter to mother nature.  Another nor’easter will bring accumulating snowfall to Southern New England Wednesday afternoon into Wednesday evening.  I’m not expecting widespread 18-24″ snow totals with this one but with cold temperatures forecast during the storm it will be light and fluffy and able to pile up quickly.  TThe Wednesday PM commute will be difficult.  Tides are approaching astronomically high levels so minor to moderate coastal flooding is again likely in all the communities still recovering from the early month barrage of storms.

Headlines

A *Winter Storm Watch* is posted Wednesday AM through Thursday AM.

NWS Early PM Headlines

General Overview

Multiple pieces of energy will come together off the Mid-Atlantic coast by Wednesday AM.

WPC Surface Fronts/Precipitation Wednesday 8 AM

High pressure is in good placement across Southern Canada to help drain cold air into New England.  The March sun angle will limit precipitation during the daylight hours.  However, precipitation rates will increase towards sunset and that is when the majority of the snow will fall.  Snow starts after 12 PM and continues until the early AM hours.

I think the worst of the storm will be from 6 PM to midnight.  The storm pulls away Thursday AM and weakens.  Model guidance has shifted west today (like every storm in the past few weeks).  A widespread 6-12″ will fall in across Central and Eastern MA, Northern RI, and Northeast CT.

NWS Snow Worst Case

More tomorrow as the exact tracks starts to be locked in.
