We are approaching our first impactful and widespread snow storm of the season in southern New England, which will begin tonight and continue into Sunday afternoon. The National Weather Service has issued a winter storm warning for different areas of Massachusetts and New Hampshire.
There is a lot riding on this, especially along the coast, where the thought process continues to focus on the relatively smooth ocean water and the gusty easterly winds that will develop. This will undoubtedly be a determining factor in terms of total snowfall across the entire area (from coastal to inland communities), which will be greatly affected by wind direction affecting overall temperatures.
When does it start snowing in Boston?
Right now it looks like the east wind is winning by keeping snow amounts low along the Coastal Plain, but we won’t let our guard down in case there are some subtle changes once the storm starts overnight and into Sunday.
Expect clouds to increase and thicken throughout this afternoon with some coastal flurries and snow showers developing. Highs reach the mid and upper 30s to the south and the upper 20s to the north.
New England Snow Forecast
Snow falls from west to east tonight and increases overnight; some communities see snow rates of 1 to 2 inches per hour after midnight. Along the immediate coast, the coast south of Boston and over the Cape, rain will mix and the precipitation is expected to become total rain.
Winds will also increase overnight as low pressure develops just south of the New England coast with an easterly/northeasterly wind gusting to 40, up to 50 at dawn over the Cape and Islands. Overnight lows fall into the low 20s to low 30s inland, low 30s along the coast, and low 20s in northern New England.
Precipitation is expected to taper off slightly after sunrise with snow inland, mix/rain along the coast with temperatures starting below freezing inland and above freezing along the coast. the coast.
At this time our system will begin to move away from the region allowing cold air to return to the area via a gust of northerly wind causing a flash freeze on untreated surfaces…we will also see another round of precipitation which will coincide with the cold air returns, that is when the coast will begin to recover from the snow accumulations.
Massachusetts Blizzard Live Radar
Morning temperatures start around 30 degrees inland, 20s north, mid 30s on the coast, and drop back to the 20s in the afternoon via a gusty northerly wind. The snow moves out early Sunday night as low pressure exits to the east. Very cold start to the work week with early morning temperatures on Monday morning, rising to the 30s in the afternoon with some sunshine.
The pattern remains active as we will be closely monitoring the arrival of our next system in the middle of next week, which will likely have significant impacts on the region with heavy rain and gusty winds. Beyond that, another storm is possible over the weekend, but it looks a little colder. More on that in the coming days, one storm at a time….
