Winter Storm Incoming: Rain, Snow, Ice, Alerts

The storm that has been forecast for about a week now is on the final approach. The storm center will cross northern New England, likely right along the Canadian border. A secondary low will form offshore, but will stay too far out to sea to bring impacts on Saturday.

There has been no significant changes to the forecast from yesterday. With that in mind, here is the latest in timing and impacts:


NEW ENGLAND ALERTS



NORTHERN NEW ENGLAND IMPACTS


Much of the north country will see several inches of snow before a changeover to a mix and rain occurs. This changeover will spread from south to north, the further north you go, the more snow will accumulate. Some freezing rain is also possible as the changeover from snow to rain occurs. Southern parts may see up to 1.75 inches of rain. The NWS states:

"Across the foothills snow will transition to a wintry mix, including freezing rain through midnight with light ice accretion. Snow will persist the longest in the mountains, but during the pre-dawn hours precipitation will change to a wintry mix followed by rain being the dominant p-type across the entire area Friday morning. Rainfall amounts are generally in the 1.25 to 1.75 range with locally higher amounts near the Mid Coast and White Mountains. The 7pm HREF shows low probabilities of rainfall rates of 1 inch per 3 hours tonight near the coast, which may lead to ponding of water on roadways."


NORTHERN NEW ENGLAND TIMING


Thursday: Snow showers beginning midday and spreading south to north, a changeover to rain will also spread north to south.


Thursday night: Rain in southern New Hampshire, valleys of Vermont and western and coastal Maine, some mixing possible; snow in northern Maine and White Mountains.


Friday: Steady rain in the morning with showers continuing in the afternoon; mix and snow in northern Maine; showers may mix with snow in the afternoon across northern areas.


Friday night: Precipitation ending in southern areas, some mix and snow showers continue in northern areas.


Saturday: Clearing up in most areas, northern Maine will see snow showers taper off in the morning.


SOUTHERN NEW ENGLAND IMPACTS


Southern New England will see a widespread half an inch to inch of rainfall overnight tonight. The NWS states that some rumbles of thunder may even occur at times overnight. Gusts along the coast, especially over Cape Cod could be in excess of 35-45mph. There are hints that stronger gusts could also occur. Winds will be near advisory level, but the chances of damaging winds are currently too low for an alert. The NWS states:

"Piggybacking off of the sentiment of the previous shift, confidence is too low in persistent advisory level winds to hoist a wind advisory."


SOUTHERN NEW ENGLAND TIMING


Thursday: Showers begin in the afternoon, some mixing possible in central and western Massachusetts.


Thursday night: Soaking rain, widespread inch possible, quick rumbles of thunder in places.


Friday: Morning rain and showers, peak winds in the morning.


Friday night: Drying out, clouds part overnight.
