Sunny skies today for the Vernal Equinox. You’ll notice that it’s spring by looking at the calendar, NOT by how it feels outside. Temperatures, yet again, will be well below average. Clouds will increase overnight with our approaching storm system.
The fourth nor'easter since March 2 will arrive Wednesday, and linger into early Thursday. The storm coupled with strong high-pressure over Ontario that will generate wind from the northeast gusts past 50 mph at the coast once again. Coastal flooding will be a concern. Minor to moderate flood is possible during the late Wednesday night high tide.
Snow arrives early morning Wednesday in Connecticut, then spreads to the north and east into Maine by late day. Along the coast and south of Boston may be a mixture of rain and snow. This also means it'll be a very wet snow along Interstate 95 and towards the water.

Snow will be heaviest Wednesday afternoon and overnight, with snowfall rates once again in the order of 1 or 2 inches per hour.
Latest Timeline, Expectations for This Week's 4th March Nor'easter
The exception is in Vermont, far northern New Hampshire and much of the state of Maine where snow will be lighter or maybe miss altogether.
Snowfall amounts in the order of 6 to 12 inches are likely.
Snow continues in Maine Thursday, otherwise a mixture of sun and clouds, and cold, with a high temperature in the 30s. Wind from the northwest will continue gusting past 40 mph.
High-pressure should bring in brighter and pretty cold weather for late in the week and start the weekend.
The next system will be racing across the country and may arrive in New England before the weekend is done, with another mixture of rain and snow, but it DOES NOT look like a coastal storm at this time.
