SYNOPSIS
High pressure builds in through Tuesday. Low pressure tracks south of the Gulf of Maine Wednesday. High pressure returns Thursday followed by another approaching low from the west on Friday.

NEAR TERM /THROUGH TONIGHT/
Update...
Winds are already gusting to around 30 mph across the north.
Increased clouds early this morning for northern areas based on latest satellite imagery and observations. Otherwise, forecast remains on target.

previous discussion Cold front will exit the coast through early this morning.
Strong Canadian high pressure will ridge down across the area from Quebec province with dry weather conditions today. Deep layered northerly flow is expected with gusts as high as 25 to 30 mph at times. Expect partly sunny/mostly cloudy skies this morning to give way to mainly sunny conditions by afternoon.
Afternoon highs will range from the low to mid 50s across the north and near 60 for the Bangor region and Downeast. High pressure to our north will result in mainly clear skies this evening, followed by some increasing high level clouds late.
Lows tonight will range from the upper 20s to around 30 north and mid 30s for the Bangor region and Downeast areas.

SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/
By Tuesday morning weak sfc ridge axis will be losing it/s grip on the region with upr trof approaching from the OH/TN Valley area.
Enough dry air should be able to hold showers off during the day on Tuesday, if not keeping them to our west into Tuesday evening. By 06z Wed, sfc low will have developed in the vicinity of the NY Bight into srn New England and will be moving into the Atlantic overnight.
However, as it does so and inverted trof likely sets up twd the area with H8-H7 theta-e convergence developing Tuesday night in H8 warm advection. Have bumped pops further north around 06z Tuesday too allow for slgt chc of showers as far north as all but northern Aroostook. Measurable rainfall likely to be only a few hundredths of an inch to the north of Bangor on Tuesday night.

May see some lingering showers Wednesday morning as low pulls into the open Atlantic with skies clearing across the north. Due to cloud cover and showers, warmest temps can be found acrs the north and east with highs topping out near 60 degrees. Brief s/wv ridging will take hold of the area Wednesday night ahead of next upr low dropping twd the area by the start of the extended.

LONG TERM /THURSDAY THROUGH SUNDAY/
Thursday morning will start out with upr ridge axis over the southeast U.S. with large upper low over the Prairie Provinces of Canada into the northern Plains. Our region will see upr s/wv approaching from the west with differences in timing and strength of the wave. Cannot rule out showers falling over the region but still not confident on when that may be. Most likely timeframe looks to be Thursday afternoon and evening but significant uncertainty still remains. Good news that this will likely be a fairly light rainfall at this point.

As wave drops south of the region Thursday night it should leave dry weather in it/s wake. Have removed pops from Friday, however uncertainty in the extent of potential blocking setting up. This may keep showers backing in fm the Maritimes but ensembles building upr ridge in quick enuf to prevent this fm occurring. By late Friday night/Saturday morning occluded front will be approaching the area bringing showers to the area for the weekend.
