A rare June Nor’easter
A Nor’easter, the type of weather system that usually brings snowstorms to New England in the wintertime, will make a rare June appearance today, creating breezy conditions and drenching rain. This is the same storm system that brought severe weather, including a large complex of thunderstorms known as a derecho, to the Midwest on Wednesday evening. Having moved through the Mid-Atlantic states on Thursday, the storm system moved offshore overnight and underwent a process called cyclogenesis, forming a strong low pressure center. That low will move northeastward (hence the name) past the tip of Cape Cod today, bringing the aforementioned rain and wind to our area.
This month is poised to be one of the wettest months of June ever recorded in Boston. Already, 6.88 inches of rain have been recorded, a departure of 5.04 inches from the normal value at this time of the month. Today’s Nor’easter is expected to drop around another inch of rain on the already-soaked area, creating the possibility for some flooding. While the month is not yet even halfway over, it remains unlikely that the all-time June precipitation record of 13.20 inches in 1982 will be surpassed this year.
