Metro Boston, North Shore and western suburbs: Showers and thunderstorms emerged throughout a good portion of western and central New England on Wednesday, however it was a very nice day locally with a good amount of sunshine. By late afternoon fog started to roll in along the coastline and spread further inland during the overnight.
Thursday morning many of us wake to a foggy start to the day. Dense fog in areas has kept the visibility under 1/2 mile at times and this will be with us through a good portion of the morning commute. With high pressure over the Canadian Maritimes and low pressure south of us we are in a light but steady flow of damp air off the ocean. This will persist through the day which may keep pesky low cloudiness for a good part of the day along the coastline, with breaks of sunshine possible. Inland, clouds should break away to a partly cloudy afternoon. There is a slight chance of an afternoon shower or thunderstorm through the interior.
Thursday night could be another foggy night, especially along the shore, with generally mostly cloudy skies elsewhere. It remains to be seen how widespread and dense the fog will be overnight if it does occur.
Friday, high pressure remains in the area and should keep most of us dry with partly cloudy skies on average. A warm front will also be approaching from our west. There is a chance of an afternoon shower or thunderstorm but they would be far and few between and most likely occur through the interior. You will notice it becoming more humid with the approaching warm front.
The start of the holiday weekend has changeable skies, generally partly cloudy on average, humid and warmer temperatures. By Sunday there is a chance of a few showers thrown into the mix.
Labor Day continues with partly to mostly cloudy skies and a chance of a few showers and thunderstorms. Again, most of this activity may very well occur through the interior.
Keep in mind that most of the time it is expected to be dry through the Labor Day Weekend, but you may have to deal with a few showers at times. No general rain is expected and outdoor activities should be fine, except for the possibility of a brief interruption from a pesky shower.
