DAYS 1-5 (NOVEMBER 17-21)
Some areas of dense fog are around to start today due to increased moisture from off the ocean to the south. Some limited visibility has resulted, slowing travel especially in areas south of I-90 so use caution if traveling early today. This is also a signal for a rather warm November day ahead, not record shattering by any stretch, but a 60+ day for most of the region ahead of an approaching trough. This trough will drive a cold front through here tomorrow that will put an end to the mild party. It now appears that the bulk of the rain shield from a coastal / ocean storm will stay offshore, but still can clip parts of far southeastern MA during the morning Saturday. Otherwise, just look for rain showers pushing through with the cold front mainly during the first half of Saturday before we see a drying trend quickly set in, and a clearing/colder trend to follow as the cold front moves offshore. This will set us up for a breezy, chilly, but bright day on Sunday. Similar weather continues Monday with high pressure to our northwest. This high will settle across the region Monday night, which will be a cold one, and a very chilly start to Tuesday with bright sun. The sun fades later Tuesday as the next trough and developing low pressure area approaches from the west, and may spread its precipitation into our region as early as Tuesday night. Will work on that timing – system can be a touch slower too.
