Yesterday’s forecast called for gradually improving conditions through the day with the chance for a short-lived shower or downpour. Unfortunately, said forecast proved to be a disaster as numerous showers, downpours and embedded thunderstorms developed over the area and persisted through much of the afternoon, dumping some hefty rainfall on parts of the Cape. In fact, some spots recorded nearly 2 inches of rain.
The downpours were a fitting end to what proved to be another very damp month across the area. Hyannis finished May 2017 with 6.45″ of rain (the long-term May average is 3.50″) and Chatham recorded 5.64 inches (average of 3.73″).
However, some locations across the Cape saw significantly higher totals – with parts of Falmouth recording almost 9 inches of rain in the month.
Here is a look at the totals recorded by CoCoRaHS observers yesterday, followed by a look at April and May totals across some of the area:
