The Boston and Cambridge areas will experience a soaking, day-long rainstorm today as a low pressure system moves in from the west and eventually heads out to sea. While the storm will make for rather cold and dreary conditions for those out and about today, it will also bring some much-needed precipitation to an area that has received an abnormally low amount of rain so far this spring.
As of yesterday, the Boston area had been running a precipitation deficit of 6.58 inches from climatological normals since the beginning of the year. Furthermore, according to the National Oceanic and Atmospheric Administration’s U.S. Drought Monitor, 84% of the state of Massachusetts was experiencing moderate to severe drought as of April 24th. Today’s storm should bring an additional 0.5 to 1 inches of rain to our area, so drought conditions are likely to persist, although their severity should be lessened.
