One wind system heaves to the east, another one heads this way

Stormy weather marches toward the Midcoast: ‘Major snow,’ meteorologists say

MIDCOAST — As the winds from the powerful weekend storm finally simmer down, and clouds dissipate, another storm is bearing down. The Midcoast is under a winter storm warning, as the next system roils across the country and then up from the mid-Atlantic. And it is apparently going to drift back and forth from the Maritimes to the Maine mountains.

"The low will slowly continue northeast into the Maritimes Thursday then drift back to the west over northern Maine Thursday night and Friday," according to the National Weather Service, in Gray. "A trough of low pressure will linger over the area Friday night and Saturday."

The action is to start Wednesday afternoon, as low pressure sinks southeast of the Gulf of Maine. The clear skies will continue through 6 a.m. Wednesday and then clouds will come, bringing, “major snow," said the NWS.

 Institute the drill:

Fill bathtubs, locate the shovel, get flashlights ready, stay off the roads and away from plows, and....

Enjoy the snow! 

"Increasing frontogenesis will already be ramping up the forcing for ascent Wed afternoon, but as the mid level lows deepen deformation will be increasing along and NW of their path. This will likely lead to some intense banding for interior parts of New England," meteorologists said, in their 9:30 a.m., March 6, report from Gray.

Depending on flow, the Midcoast could get some rain, while western Maine is to get snow in the double-digit amounts.

But, they warn, that rain will likely flip back to heavy snow by Wednesday evening.

Then, there is the wind — 30 to 40 mph gusts anticipated. Heavy wet snow, heavy wind.

The storm warning, as issued March 6, advises: "A strong coastal storm will develop south of New England and move into the Gulf of Maine Wednesday evening into Thursday. Snow is expected to spread north across the region during the afternoon and evening Wednesday. There is some potential for the snow to mix with rain at the coast as precipitation begins on Wednesday. Snow will become heavy Wednesday evening and overnight with dangerous travel conditions expected. The storm will weaken and drift west Thursday, but snowfall may linger, especially in the mountains, until Friday. There is high confidence that a large portion of the forecast area will see 10 or more inches of snowfall, with the highest totals near 20 inches."

"It does not look like we are putting winter to bed just yet," said the NWS, in Gray.

The coastal flooding, thanks in part due to the recent full moon and astronomical high tides, has diminished over the last few days. But within another system coming, here's what NWS said: "With residual tide anomaly expected to linger thru midweek and the approach of another significant coastal storm...another round of splash over and erosion appears likely. At this time coastal flooding is not expected...but if storm surge values increase some locations may approach flood stage Wed night.
