Metro Boston, North Shore and Metro West: While the clean up from Thursday’s powerful storm continues many of us in eastern Massachusetts are about to get another visit from Old Man Winter as a storm reorganizes and deepens over the waters to our south today. The low is expected to be positioned just south of Nantucket Island this evening then over Nova Scotia Sunday morning. It will continue to strengthen throughout its journey to our south and east bringing heavy snow, high winds, blowing and drifting snow with low visibilities late this afternoon into the evening hours. This is when the worst of the conditions can be expected.
If you need to get out today and do errands you should do so earlier rather than later. Although it remains tranquil outside early this morning I can assure you conditions will rapidly go down hill later in the day once this storm approaches and the action begins.
The National Weather Service has issued a Blizzard Warning for eastern Essex County from late this afternoon through most of tonight and a Winter Storm Warning elsewhere in our forecast area. The weather service is predicting 6 to 10 inches of snow throughout most of the forecast area, lesser amounts as you move west toward the Route 495 belt. South of Boston the prediction is upwards of 10 to 15 inches across a good part of southeast Massachusetts.
Snow breaks out early this afternoon, becoming heavy by late afternoon. The heaviest of the snow is likely between a window of 5 pm to 11 pm tonight when the bulk of the accumulations can be expected. Combine this heavy snow, increasingly gusty winds that will produce blowing and drifting snow and you have a recipe for disruptive travel conditions. As a matter of fact if you live along or near the coastline it is probably best to not travel at all if you don’t have to.
As mentioned the winds are going to be increasing over time, perhaps gusting to 25 mph by late afternoon then really becoming strong tonight with gusts of 40 to near 50 mph likely along the coast.
Coastal flooding is not anticipated anywhere along the North Shore coastline despite near full moon. Winds are expected to be northerly by the time of tonight’s high tide which may cause some splashover along north facing areas but spares east facing locations from any flood potential.
Windy and cold conditions are here for your Sunday. Many will see temperatures plummet into the single digits Sunday night. Another blustery day follows for the holiday. Then, another disturbance stares us down by late Monday night and Tuesday with, what else, more snow. However, it could mix or change to rain later Tuesday. Much more on that after we get by this storm.
