Today will feature the passage of a potent but quick-hitting coastal storm which will be moving swiftly from New Jersey into the Gulf of Maine. The storm will be strong enough to bring bands of heavy precipitation to the area, but won’t have enough cold air to produce heavy snow outside the mountains.
Precipitation is already falling in southwestern parts of the region as of this writing at 8:15 AM. Most reports from areas outside the NH Seacoast indicate that precipitation will start as a wintry mix even along the coastline before warmer air gradually works in from the East. Thus if you’re heading out this morning, take it slow and watch for slick spots on the roads.
Precipitation will remain on the lighter side this morning, but will ramp up considerably in intensity this afternoon. Heavy rain can be expected along the coastal plain while heavy snow falls in the mountains. The foothills will see “the kitchen sink” falling from the sky as cold air tries to hang on in the valleys while warm air surges in aloft. At this point, heavy precipitation rates appear to mitigate any power outage concerns posed by freezing rain, though roads will be quite slick.
If you’re curious about snowfall accumulations, I’d expect 4-8” in the mountains, 2-4” in the interior part of the foothills, and perhaps a dusting-1” closer to the coastline.
Rain and snow will wrap up from west to East tonight. High temps today will range from 30 in the north to around 40 along the NH Seacoast.
