Interior Maine and coastal Maine are experiencing two totally different seasons this week.

Look at the temperatures from 2 p.m. Wednesday, for example.


It’s in the 50s along the coast but approaching 80 degrees in Fryeburg and Berlin, NH.

In our forecasts on NEWS CENTER over the last week, we have been noting this large difference between the coast and the interior. We knew conditions would be favorable for a stiff sea breeze each day, but the fog bank sitting just offshore, flirting with parts of the coast, has been much more of a factor than expected.

There it is on the visible satellite. The sky is clear over 99 percent of the state, except along the immediate shoreline, in some towns.

Look at Kennebunk, for example, at 2:20 p.m. Wednesday. Downtown is clear, but the coast is socked in.

The fog bank formed two nights ago. It’s not unusual for fog to form in this type of a pattern. High pressure is responsible for the sun and dry weather, but its origins are Canada. That means its airmass is a chilly one. Overnight, air temperatures over the ocean dropped close to the water and dew point temperatures, and the air became saturated. With little wind and little change in the overall weather pattern, it’s been hard to clear this fog bank completely.

Expect the fog to roll back inland tonight. It’ll retreat to the coast again tomorrow, but take until Friday to completely clear out.
