Pressure and weather in Windham
Windham, including the borough of Willimantic, sits at the confluence of the Natchaug and Willimantic rivers where they form the Shetucket, in the rolling eastern uplands of Connecticut between the Connecticut River valley and the Rhode Island line. Thirty miles from Long Island Sound and higher than the coastal plain, it lands on the cold side of the rain-snow line far more often than New Haven or New London do, and the same nor'easter that gives the shore a cold rain will give Windham six inches of snow. Those coastal storms are the dominant pressure signal from December into March. The eastern uplands also catch the tail of tropical systems that curve up the seaboard in late summer — the 1938 hurricane and Hurricane Irene both did serious damage along these river valleys — and those bring the year's deepest and fastest barometric falls when they arrive.
What this means for you
Between winter nor'easters and the occasional late-summer tropical remnant, eastern Connecticut sees a wider range of pressure extremes than its size suggests. Comparing the current barometric pressure against your log across a full year will show whether it is the depth of the fall or its speed that matters more for you.
