Weather Brief Apr 18, 2019

Midcoast Forecast - April 18, 2019 PM

Hopefully you were able to soak up some sunshine on Wednesday because we won't be seeing much of it over the coming days. A warm front is lifting over the region Thursday that has pushed clouds and some light rain back into the Midcoast. We'll see a more organize batch of showers come through Thursday night as the front progresses north. The warm front is being driven by an area of low pressure exiting the Great Lakes and moving through southeast Canada. The low will pass by to our north dragging in a cold front that will stall out to our west over New York and Pennsylvania as another low pressure system rides along the front from the south. The warm front will be to our north by Friday opening the gates to brisk south winds that will pump in warm moist air into Maine. This will lead to overcasts skies with areas of fog and drizzle through the day.

Rain chances will increase heading into the weekend as the secondary low pressure system moves north into western New York by Saturday pushing the cold front into New England. This will act as a track for rounds of showers that will move along the front through the region through Saturday and Sunday as it crawls to the east making for a soggy stretch of weather for Easter weekend. Showers will taper off late Sunday as the front begins to push into the Canadian Maritimes. Rainfall totals will range between 1.5" to 2.5" for the Midcoast through this period which will lead to some areas of flooding especially across northern sections of the state where up to 2 feet of snowpack is still on the ground. The combination of moderate to heavy rain, melting snow, and temperatures in the 50s and 60s will lead to this flooding, causing rivers and streams to rise through the weekend and into the early week. Coastal flooding will also be possible during the weekend around the high time with strong onshore winds making for higher seas.

The early part of next week is still in question with the possibility of another disturbance riding north along our departing front leading to more showers on Monday. Our weather will stay active into the mid to late week with additional systems moving in from the west with more rounds of rain showers.
