Event narrative

Minor street flooding was reported in downtown Nantucket with water up to sidewalks.

Wider weather episode

Surface low pressure (and an upper level low) passed just south of New England. At the same time, a strong upper level short wave was passing to our north and a strong backdoor cold front was moving southward into northeastern Massachusetts. A mid-level deformation zone set up over southeastern MA, which allowed an area of heavy rain to persist for several hours over Martha's Vineyard and Nantucket, producing some flooding.
