High Surf Advisory for MidCoast and DownEast
As Gert exits 500 miles to the east, the shorelines will be dealing with swells and rip currents through Thursday. While the southwest coast is not under advisory, it would be wise to check with lifeguards and/or beach attendants on swimming safety. Rip currents from these tropical systems should be taken seriously. If viewing the surf from the shoreline, respect the ocean and give the waves plenty of room.
Thursday – High pressure settles in
A classic Maine summer day is on tap, featuring mainly sunny skies and breezy conditions over the north, mountains, and eastern areas. The breeze diminishes in the afternoon. High clouds may filter into southern areas in the late afternoon.
Highs for the day range from the upper 60s in the high peaks and Crown to the low 80s in the Captial District southward.

Thursday Night – High clouds overspread
Most of the state will enjoy a nice sunset before high clouds take over the state in the wee hours of Friday morning.
Overnight lows fall to the upper 40s in northern areas to around 60° along the southwest shores. Light wind.
Friday – Clouds build, showers arrive afternoon west
While clouds thicken from southwest to northeast, the bulk of the day stays dry. Showers and possibly a rumble of thunder arrive in afternoon / early evening over western and southern areas. If your grilling dinner eastern and northern areas, enjoy it.
Highs for the day range in the 70s for most of the state, with the mercury tipping 80° around Bangor.
South/southeast wind gradually increases during the day to 5-15 mph, and could become gusty along the shorelines and western mountains by evening.

For Sunday, southern and eastern areas appear dry. A spot shower is possible for the mountains and north as a weak trough works through, with any activity appearing brief. Sun increases for all in the afternoon, making for a nice evening statewide to wrap up the weekend.
Warm weather arrives for Monday, with comfortable humidity.
Eclipse update – Best viewing conditions coast
While this GFS graphic indicates relatively clear skies near the peak of the eclipse, I can’t rule out some fair weather clouds popping up over interior areas. Northern areas still concern me for some high clouds in association with a storm that impacts Labrador. At this point the coast appears to be the best bet for a clear view.
This is a 60% eclipse here in Maine. It begins around 1:30 PM, peaks around 2:45 PM, then clears around 3:50 PM.
Remember to use protective eyeware, and refrain from looking at the eclipse directly.
For more information on how to safely view the eclipse, please check the NOAA Eclipse 2017 website. Be aware of knock off viewing glasses that do not meet ISO 12312-2 international safety standards. You can get more detailed information from WGME Chief Meteorologist Charlie Lopresti’s blog Check in with Charlie for more eclipse details.
