Overview
- A broad dome of high pressure continues to deliver unseasonably warm, mostly dry weather in many regions, with New Mexico near record highs and parts of the South and Mid-Atlantic in the 60s to 70s.
- National Weather Service alerts call for a very windy period Wednesday night into Thursday, with coastal New England gusts potentially reaching 60 mph and a risk of tree damage and isolated power outages.
- A fast-moving cold front will bring increasing clouds and brief, mainly light showers late Wednesday into Wednesday night in several markets before skies clear again Thursday.
- Astronomically high tides tied to the midweek supermoon are expected to produce localized coastal flooding in the Boston area, including possible closures on prone roadways such as Morrissey Boulevard.
- Forecast models point to a stronger front late Sunday that should drop temperatures sharply and may introduce the season’s first rain-to-snow or mixed precipitation in parts of the Great Lakes and Northeast, though the track and local impacts remain uncertain.
