The first severe weather outbreak of the 2014 summer severe weather season occurred on Thursday July 3rd, 2014. As a slow moving cold front approached the region with unstable conditions in place and sufficient wind shear profiles, a few clusters of strong to severe thunderstorms developed over portions of Western, North-Central and Northeast Massachusetts and Southeast New Hampshire. These storms were responsible for pockets of wind damage and hail across portions of Western-Central Hampshire County Massachusetts and also across portions of Northeast Massachusetts including the Billerica, Lawrence and Methuen area into North-Central Essex County Massachusetts. Another severe thunderstorm organized over Rockingham County NH impacting the Newmarket to Portsmouth, NH area.

Another line of strong to severe thunderstorms organized across Eastern New York. This line would traverse much of Massachusetts and Northern Connecticut producing wind damage, some of which was significant and hail across portions of this region. Some of the more significant damage locations were across Northampton and Whatley Massachusetts and in New Britain, Connecticut, a 63 MPH measured wind gust was recorded. The southern storm across Connecticut would intensify as it entered South-Central Massachusetts causing pockets of wind damage and hail in this area. It would intensify further as it affected communities such as Natick, Wayland, Wellesley, Waltham and into Metro-West and the North Shore with numerous pockets of tree and wire damage and even structural damage with a section of roof blown off an apartment complex in Waltham, Massachusetts. Several trees landed on cars and homes in Natick, Wayland and up through the North Shore of Massachusetts.

On Friday July 4th, 2014, Hurricane Arthur would make its closest approach to Southern New England. An outer rain band organized between the circulation of Hurricane Arthur and the cold front that was gradually pushing its way through the rest of Southern New England. This set the stage for very heavy rainfall across portions of Southern and Central Rhode Island and Southeast Massachusetts. Hardest hit were portions of South Coastal Massachusetts across the Greater New Bedford, Wareham, Plymouth area where 6-8″ of rain fell. This caused a significant flash flood episode across urban areas of New Bedford and Fairhaven with other flash flood reports around the Wareham and Plymouth area. Surrounding this area was a widespread 2-5″ rainfall across portions of South-Central Rhode Island and Southeast Massachusetts with more minor urban and poor drainage flooding.

Across Cape Cod and the Islands, winds picked up after 600 PM Friday Evening causing isolated pockets of tree and power line damage and isolated power outages along with 1-3″ of rainfall and urban and poor drainage flooding. Wind gusts on Nantucket Island were over 60 MPH with sustained tropical storm force winds. This downed a few trees and caused power outages to over 2700 people on the island. There were also numerous streets flooded in downtown Nantucket for a time during the evening hours. Cape Cod had wind gusts in the 40-50 MPH range. Wind on Martha’s Vineyard were also gusting to the 40-50 MPH range.
