00:33 Thundersnow In Boston In Boston, in the middle of Winter Storm Neptune, The Weather Channel meteorologist Reynolds Wolf experienced some thundersnow.

EDITOR'S NOTE: This winter storm has been named Winter Storm Neptune. The information below is no longer being maintained. For the latest forecast and analysis, go to our Winter Storm Neptune forecast article.

A Valentine's weekend snowstorm is increasingly likely in New England, and it has the potential to dump a foot or more of additional snowfall on snow-weary locations such as Boston.

This snowstorm would be accompanied by strong winds that could create blizzard conditions and bitter cold temperatures.

This comes on the heels of an almost three-week snow siege that has smashed records in parts of New England, including Boston, Worcester and Bangor.

The Timing

Those in the Northeast probably know this drill by now. Low pressure will likely intensify off the Eastern seaboard Saturday night into Sunday.

If the offshore low tracks closer to the Northeast seaboard, heavier, wind-driven snow may fall later Saturday into Sunday in New England. If the low intensifies far enough offshore, most of the significant snow will remain offshore.

It is still a few days days out from the event and the upper-level energy responsible for this potential snowstorm is still 2,200 miles away in Nunavut, Canada , in a more data-poor area for our forecast guidance to sample its strength accurately.

As a result, the forecast track may shift as we near the event, something commonly seen in many potential East Coast storms.

However, the trend is increasingly toward a track close enough to bring heavy snow and strong winds to at least coastal New England. Here's our latest forecast timeline:

Friday: Another arctic front will spread a stripe of mainly light snow and gusty winds through the Great Lakes.

Saturday: Light to moderate snow spreads from the eastern Great Lakes into the Northeast as the arctic front advances. Snow is possible from the Appalachians and Virginia north to New York state and much of New England by afternoon (see map at left).

Saturday night: Heavy snow and increasing wind possible in New England, particularly near the coast from Maine to southeast Massachusetts. Snow and wind also farther west over the Hudson Valley, NYC metro, central/western New York, northern Pennsylvania, at least northern New Jersey.

Sunday: Heavy snow and high winds possible in much of New England. Blizzard conditions possible. Snow winds down farther west.

Sunday night: Snow may linger in Maine, Cape Cod, but should taper off elsewhere. Significant blowing/drifting snow continues over much of New England.

Regardless where the low tracks, behind the arctic front and intensifying offshore low, bitterly cold air will settle in, driven by strong winds, leading to dangerous wind chills.

Temperatures may remain stuck in the single digits or, at best, teens much of Sunday in New England, with morning lows in the single digits above or below zero.

Updates once an hour.) (Additional forecast snowfall through 8 p.m. EST Sunday, when most of the accumulation will have ended. Updates once an hour.)

Potential Impacts

Snow: This storm has the potential of dropping a foot or more of snow in parts of coastal New England. For now, the best chance of at least one foot of snow is in coastal Maine.

For the snow-sieged Boston metro area, 6 inches of snow seems a strong bet, with the potential of a foot or more depending on the exact low track.

Localized areas of New England may see 20+ inches of total snowfall.

(FORECASTS: Portland, Maine | Boston )

Light to locally moderate amounts of snow are expected farther west, including Long Island, the NYC metro, the Hudson Valley, central and western New York, Pennsylvania, New Jersey, the Appalachians and Great Lakes.

(FORECASTS: NYC | Philly | Syracuse )

Wind: Strong winds gusting over 50 mph are possible in coastal New England, Long Island, perhaps as far south as the Delmarva Peninsula by early Sunday morning, continuing at least into Sunday afternoon before slowly winding down Sunday night.

This may lead to considerable blowing/drifting snow and blizzard conditions, at times, particularly in rural areas. Some sporadic power outages and downed tree limbs are possible, as well.

Coastal flooding: North-facing shorelines of eastern Massachusetts (Nantucket Island, Cape Cod Bay, south shore south of Boston) may see significant surge flooding on Sunday, particularly in areas affected by Winter Storm Juno a few weeks ago.

Travel: Roads conditions may deteriorate in southeast New England by Saturday night.

By Sunday, roads may become impassable from coastal Maine to eastern Massachusetts and Rhode Island with significant blowing and drifting snow.

Airport delays and perhaps some cancellations are possible as soon as late Saturday afternoon at Boston/Logan and the NYC airports. Delays and cancellations are probable Sunday at Boston/Logan, and possible in the NYC airports. If snow rates are intense enough, it's not out of the question Boston/Logan may be forced to close for a period of time Sunday.

Keep all this in mind if you have a Valentine's weekend plans, or are simply trying to clear a path in your driveway or sidewalk in the Northeast this weekend.
