Boston, Massachusetts – Rainfall deficits exceeding 4 inches since December are prolonging drought conditions along the Interstate 90 corridor.
According to the National Weather Service Eastern Region, portions of Massachusetts remain under ongoing drought conditions despite several recent winter storms. Data through Feb. 10 shows Boston has recorded 4.87 inches of precipitation since Dec. 1, 2025 — a 4.22-inch deficit compared to seasonal averages.
The latest U.S. Drought Monitor indicates moderate drought across parts of southern New England, with dryness continuing from late summer into winter in some communities. While snowfall events have provided temporary moisture, overall liquid-equivalent precipitation remains below normal.
Officials say soil moisture deficits and reduced streamflows have been observed in parts of eastern and central Massachusetts. Reservoir managers continue monitoring supply levels as the state moves toward the spring season.
Drivers along Interstate 90 (Massachusetts Turnpike), Interstate 93, Interstate 95, and Interstate 91 may notice lower water levels in streams and retention areas near roadways.
Forecasters caution that sustained above-normal rainfall would be needed to significantly reduce longer-term deficits.
Farmers, landscapers, and municipal water managers are tracking groundwater conditions closely heading into late winter.
Residents are encouraged to practice water conservation and monitor updates as drought classifications are reviewed in the coming weeks.
