Coastal storm to slam New England

By Jason Samenow

Impact on D.C. metro region: a short soaking

Rainfall potential Thursday thru Saturday over the mid-Atlantic & Northeast from GFS model. About 0.5-1.0" is projected over the D.C. area & 1-2" over New England.

As low pressure quickly develops over the mid-Atlantic Thursday, ready yourself for a six to 10 hour period of steady rain from the pre-dawn hours through mid-afternoon in the D.C. metro region. Up to an inch of rain or so is possible.

The storm will have not matured sufficiently to produce high winds here in Washington when the rain falls. But some backlash wind gusts of up to 30 mph are possible Friday in the wake of the storm.

The impacts in Washington, D.C. will be mild compared to what southern New England faces Thursday night into Friday as this fast-moving storm deepens into a tried-and-true 'Noreaster.

AccuWeather and Weather.com are in full alert mode over the impending storm, highlighting the potential for high winds over much of the Northeast.

Surface map of weather features over New England at 7 a.m. Friday morning. The black lines of equal pressure (isobars) are close together, indicating high winds.

AccuWeather warns that (over the Northeast): "Gusts of 50 mph (80 kph) are possible with this storm over a broad area and will be strong enough to down trees, lead to sporadic power outages and toss your trash cans across the neighborhood."

Weather.com cautions: "Apart from typical concerns over power outages, this wind could take a toll on the beautiful fall foliage currently underway, not to mention downing some trees or limbs."

In addition to the high winds, which will continue in New England through Saturday night, rainfall totals will probably be about double (2" or so) what they are in the mid-Atlantic region as the storm slows to a crawl off the coast of Maine. The Nor'easter may pull down enough cold air for snow in the Adirondacks and high terrain of Vermont and New Hampshire.

By Sunday, the entire East Coast should clear out as sprawling high pressure overtakes the eastern half of the country.

Comments

The first of many this season, although later ones will be known as "duds". The forecast will talk about a snowstorm, but it won't get going until it passes by us.
