We’ve endured plenty of chilly Frist Night celebrations over the years around there. This year won’t be one of them.

High pressure slides offshore tonight and Friday, with dry and mild conditions expected. Clouds start to stream in Friday night ahead of a low pressure system moving this way. Saturday will be another mild, albeit cloudy, day. Showers will develop toward evening, becoming a steady rain overnight. So, if you’re heading out to celebrate New Year’s Eve, bring a raincoat. The rain should come to an end New Year’s morning, then skies clear out during the afternoon as the low pulls away and high pressure builds back in. For Monday, we should have partly to mostly sunny skies and mild temperatures, perfect for viewing the Winter Classic at Fenway (not so perfect for the ice condition).

Thursday night: Clear to partly cloudy. Low 28-35.
Friday: Partly to mostly sunny and mild. High 48-55.
Friday night: Increasing clouds. Low 37-44.
Saturday: Cloudy with showers developing toward evening. High 51-58.
Saturday night: Periods of rain. Low 43-50.
Sunday: Showers end early, skies start to clear out in the afternoon. High 50-57.
Sunday night: Clear to partly cloudy. Low 29-36.
Monday: Partly to mostly sunny. High 44-51.
