Chestnut Hill residents can expect a crisp, sunny weekend before fall weather takes a turn with showers arriving by midweek. The calm stretch won’t last long, and drivers should be alert for wet pavement on Route 9 and local side streets starting Tuesday night.
According to the National Weather Service in Boston, clear skies will continue through Sunday with highs near 69 degrees and nighttime lows in the mid-40s. Winds remain light, but conditions shift Monday when highs climb to 74 under sunshine before clouds return Monday night. By Tuesday evening, a 40% chance of showers develops as a southwest wind pushes moisture into the region.
Eastern Massachusetts, including Chestnut Hill, Boston, and Waltham, could see slippery road conditions late Tuesday into early Wednesday. Commuters are advised to give extra travel time, check headlights and wipers, and use caution on highways and secondary roads. With September bringing shorter daylight hours, visibility challenges may increase during evening commutes.
Midweek remains unsettled, with a continued 30% chance of showers Wednesday and Thursday. Despite the rain, temperatures stay mild, hovering in the low 70s by day and mid-50s overnight. By Friday, conditions improve with mostly sunny skies and highs near 73, returning the area to a more stable fall pattern.
