Boston gets one relatively quiet weather day Thursday before a rough coastal weekend moves in. Thursday is expected to be dry and cool, with temperatures in the low 60s east and northeast winds. By Friday night, rain and stronger winds take over.
Thursday Stays Dry, But The Breeze Builds
Thursday will be dry, cool and breezy, with northeast winds and rough seas already developing offshore. The National Weather Service describes the day as cool, dry and breezy, with rough seas already developing offshore.
Friday Night Marks The Turn
Rain and lowering ceilings move in Friday, with strong northeast winds developing. Friday night brings likely showers and strong winds. Storm watches are in effect over the waters.
Coastal Areas Face The Biggest Trouble
Coastal flooding is possible from late Friday through Sunday. A High Surf Advisory is also posted from Friday morning through Sunday evening. Offshore seas could reach 21 feet Friday night, and beach erosion is possible. Drivers should not go around barricades or through water of unknown depth if shoreline roads begin flooding.
Wet, Windy Weekend Then A Slow Reset
Saturday looks like the storm's roughest stretch for Boston, with rain showers, a high near 60 and north winds of 24 to 29 mph that could gust to 41 mph. Showers and thunderstorms remain possible Saturday night and Sunday, with local gusts up to 40 knots Sunday. The Wednesday's forecast update had already flagged a potentially strong coastal low, flooding, erosion and rough seas; the National Weather Service issued a High Surf Advisory Thursday.
Monday looks mainly VFR, with a chance of showers. The low should exit east by Tuesday.
