High pressure enters the region on Sunday
On Sunday, high pressure approaching from the west moves into Maine beginning a dry trend that is likely to last into the middle of next week. As the high brings cooler, drier air down from Canada, the humidity that has been lingering the past several days will also be leaving the region making for more comfortable conditions. Temperatures on Sunday are likely to be on the warmer side farther south and east, reaching the mid and upper 70’s, while areas towards the north and west stay in the upper 60’s and lower 70’s. The offshore flow should limit the strength of the sea breeze and allow the coast to stay in the 70's. Skies should otherwise be sunny with a few clouds possible over the mountains later in the day. There also exists a chance for some fog overnight.
Another dry and clear day to start the week off on Monday
High pressure will continue to stick around on Monday allowing for another dry day. Humidity will also still be quite low. Skies should also remain sunny although a few clouds may work into the area during the late evening. Areas of fog may also develop. Temperatures are likely to reach the upper 70’s and possibly even the lower 80’s in the south and east although a sea breeze is likely to keep the coast a bit on the cooler side. Towards the west and north, temperatures should remain in the low to mid 70’s.
The heat makes a return on Tuesday
As the area of high pressure moves east on Tuesday, the wind direction will shift towards the southwest allowing warmer air to be transported into the region. Temperatures are likely to reach the 80’s across most of the state with some places east of the mountains reaching the upper 80’s. However, a sea breeze is likely to keep coastal temperatures below 80.
