Weekend forecast details
Today and Sunday will be largely partly sunny, interrupted by a few spotty showers tied to a weak system moving through Greater Boston. The cold front that moves through tomorrow has the greatest chance of producing isolated showers in southeastern Massachusetts, but most areas should see only brief wet weather or remain dry. No severe conditions are expected; the primary impacts will be minor interruptions to outdoor plans.
Temperatures and short-term outlook
Boston’s forecast highs are expected to be in the low to mid 70s both today and Sunday, near the long-term average high of 74 degrees. MetroWest may be noticeably warmer, with readings climbing into the upper 70s and approaching 80 in some spots. After the front passes, Monday will be cooler with highs in the upper 60s to lower 70s and lots of sun. Temperatures rebound Tuesday and Wednesday into the mid to upper 70s.
Seasonal context and long-range notes
Long-range guidance suggests this fall may be warmer and slightly drier than average for Boston. September normally cools from an average high near 78 degrees at the start of the month to about 68 degrees by the end of the month. Daylight shrinks through September by roughly one hour and 22 minutes, and sunsets fall before 7 p.m. after September 11.
Drought and rainfall context
New England is already experiencing drier-than-normal conditions, and the region is likely to face a moderate drought. New Hampshire and Maine are currently seeing moderate to severe drought levels. Boston received about 5 inches of rain over the summer, making it the 12th driest summer on record for the city. These shortages are affecting soil moisture, river flows, and the outlook for fall vegetation.
Fall foliage and gardening notes
Dry conditions can bring about an earlier and more vibrant start to fall foliage in many areas, but the overall quality could be reduced by secondary problems. Leaf fungus and insect pests that thrive in stressed trees may limit color intensity in places. As the growing season winds down, many gardeners plant hardy fall flowers like mums, which tolerate cooler temperatures and are a common seasonal choice.
Tropical and broader weather monitoring
Atlantic tropical activity is being monitored this season. A tropical system that could become Hurricane Gabrielle may form off the African coast, but current guidance favors it curving out to sea and not affecting New England. The region should continue to monitor forecasts through the fall for any changes.
