Weather Brief Feb 12, 2019

Midcoast Forecast - February 12, 2019

Clouds have blanketed the sky Tuesday ahead of our next winter storm that will bring widespread snow to the region Tuesday night and into Wednesday with some mix along the coast. A broad area of low pressure moving north and east through the Great Lakes is pushing moisture into the cold air in place over New England that will lead to this round of winter weather. Morning low temperatures dipped down into the single digits Tuesday morning and only reached the 20s during the afternoon but these will continue to climb along the coast as warm air noses in off the Gulf of Mexico as we move through Tuesday night and into Wednesday morning as temperatures reach near or slightly above the freezing mark.

Snow will begin across the Midcoast shortly after sunset Tuesday and ramp up quickly through the early night with heavy to moderate periods of snow continuing through the night. This is when the bulk of the snow accumulation will take place. As we near sunrise on Wednesday, temperatures along the coast will begin to enter the tipping point where snow will change to sleet and then some rain but at this point, most of the snow will already be on the ground. Precipitation will start to taper off into the midday hours with a break in the action during the afternoon as low pressure moves through Maine then begins to exit east into the Canadian maritimes. Scattered snow showers will wrap around on the back side of the storm late Wednesday that could lead to additional dusting to 1 inch for some locations. Snow totals will range between 6 to 12 inches across the Midcoast with the lower end toward the coast where mixing will take place.

Winds will be brisk out of the east and southeast through Tuesday night and the first half of Wednesday before switching out of the west and southwest in the wake of the storm which will build seas up to 12 feet offshore and up to 6 feet for Penobscot Bay. A Gale Warning is in effect through Wednesday with sustained winds of 20 to 30 knots and gusts up to 45 knots.

We'll see a break in the action Thursday with clouds lingering over the region as another storm tracks in behind our mid week storm. This will pull in milder air making for a mainly rain event Friday and into early Saturday morning. This will be followed by cooling and clearing through the weekend as high pressure sets up over the region.
