Synopsis
Low pressure slowly exits across the Maritimes tonight through Tuesday. Low pressure tracks across the Great Lakes and southwestern Quebec Tuesday night and Wednesday. Low pressure develops near the coast of the Gulf of Maine Wednesday night, that tracks into the Maritimes on Thursday. High pressure builds in Thursday night and Friday, followed by a storm system approaching from the southwest Friday night and Saturday.

Near Term - Through Tuesday
Update... Surface/upper level low pressure will remain nearly stationary across the Gulf of Saint Lawrence tonight. Snow/rain showers will diminish early tonight with the loss of diurnal heating. Moisture wrapping around the Gulf of Saint Lawrence system will then keep mostly cloudy skies along with scattered snow showers across the north and mountains overnight. Little or no snow accumulation is expected tonight. Across Downeast areas, expect mostly cloudy skies early tonight. Partly cloudy skies are then expected overnight. Low temperatures tonight will range through the 20s north, to the upper 20s to around 30 Downeast.

Previous Discussion... The region remains at the base of a closed low over the Maritimes through Tuesday morning. Another shortwave ahead of a negatively tilted trough pushes in Tuesday afternoon, with the risk of isolated to scattered snow (and possibly rain showers) mainly across northern portions of the County. Highs on Tuesday should be around 5 degrees above normal, from the lower 30s to mid 40s.

Short Term - Tuesday Night Through Thursday
Pseudo clipper-type system will be approaching late Tuesday night but likely won't see any precipitation from it until mid-morning with rain showers along the coast, rain and snow showers up through about Bangor and snow showers remainder of the area at onset. By 18z Wednesday warm advection will result in likely probability of precipitation across the northwest and portions of the Central Highlands, closer to best forcing with surface low. Temps will rise into the lwr 40s over Downeast and possibly sneak into the u30s along the NB border which may result in a rain snow mix during the afternoon hours.

"Clipper low" will be captured by H5 wave Wednesday night. There are two different camps in regard to low pressure beyond Wednesday evening. 12z EC/CMC bottom it out below 990mb over Downeast while NAM/GFS (Global Forecast System) keep it slightly weaker with more of an open wave at 500mb. As low pressure moves across the area overnight, exact track will determine ptypes overnight. Given it/s projected movement and timing Downeast should remain rain/snow mix most of the night before colder air gets draw in closer to daybreak to allow precipitation to switch over to snow, though this likely to be around the time the precipitation winds down. Northern areas should remain all snow. Storm total snowfall will range from about 1-3 inches over Downeast to between 3- 6 inches from the Central Highlands over to Danforth and points further north.

Highs on Thursday will be slightly cooler than Wednesday with clouds and precipitation keeping temps down. Depending on how quickly low tracks into NB temps may reach their highs on Thursday morning before slowly falling all day. Westerly winds will begin to gust Thursday morning and continue into the evening hours with LLJ between 35- 45kts with higher terrain across the Central Highlands frequently gusting into the upper 30s.

Long Term - Thursday Night Through Monday
Low pressure will head into the Canadian Maritimes Thursday evening with strong winds continuing across the area. HIgh pressure builds in rapidly on Friday afternoon and depending on how quickly it moves out will determine lows for Friday night. At this time it appears to be brief as next system rides up along the eastern seaboard. 00z GFS is much more bullish and stronger with system tracking across western part of the area, while EC brings a weak low across the waters as does CMC. Significant amount uncertainty with chance probability of precipitation over the weekend at this point. Temps likely to drop below seasonal norms from Friday into early next week with large-scale trough impacting eastern U.S.

Marine
Near Term: A Small Craft Advisory remains in effect for much of the waters, with the exception of the intra-coastal waters, tonight. For now it appears all waters should be just below SCA (Small Craft Advisory) conditions on Tuesday as the gradient continues to weaken with the departing/weakening low in the Maritimes. However a few gusts to 25 kt over the coastal ocean waters remain possible.

SHORT TO Long Term: No headlines through Wednesday. Seas and winds slowly increase Wednesday evening with winds increasing toward gale force Thursday morning over the outer waters and over the intracoastals in the afternoon. Seas increase to 8 feet on Thursday afternoon with seas dropping below SCA (Small Craft Advisory) Friday morning.
