July 4, 2014 Rob Macedo Leave a comment

Hello to all..

..A Severe Weather Outbreak resulted in pockets of wind damage, hail, and flooding across portions of Southern New Hampshire, Western, Central, and Northeast Massachusetts and Northern Connecticut Thursday Afternoon and Evening. Those with damage and/or hail photos may send them as a reply to this message or to pics@nsradio.org and the photos will be shared with the media, emergency management and the National Weather Service. The Local Storm Report from this outbreak appears below.
..Active Week of Weather Now Focuses on Hurricane Arthur, the eventual passage of the cold front that caused the severe weather outbreak Thursday and flood/flash flood potential for the region..
..A Tropical Storm Warning remains in effect for Barnstable and Nantucket Counties (the area from Woods Hole to Provincetown including Nantucket Island). Sustained winds of 25 to 35 MPH with Gusts to 50 MPH are possible in Barnstable County while sustained winds of 35-45 MPH with gusts to 60 MPH are possible on Nantucket Island based on the current track of Hurricane Arthur. Isolated tree and wire damage and power outages are possible. Heavy Rainfall of 2-4″ with isolated higher amounts up to 6″ are possible in the Tropical Storm Warning area with the potential for urban and poor drainage flooding in this area. Some moderate storm surge coastal flooding is possible on north and east facing locations of Outer Cape Cod and Nantucket Island..
..A Flash Flood Watch is in effect for Noon Today Through late tonight for Eastern Massachusetts and Rhode Island. Heavy Rainfall of 2-4″ with isolated higher amounts up to 6″ are possible in the Tropical Storm Warning area with the potential for urban and poor drainage flooding in this area as well as the potential for small stream flooding..
..A Flash Flood Watch is in effect through this evening for Western and Central Massachusetts, Southern New Hampshire and Northern Connecticut. In this area, heavy rainfall will be more localized but heavy rainfall rates of 1-2″ per hour where heavier downpours may lead to flash flooding particularly in urban and poor drainage areas..
..SKYWARN Activation with Ops at NWS Taunton will commence no later than 200 PM today lasting through early Saturday Morning for flash flood issues and the potential for tropical storm force winds on Nantucket Island and portions of Cape Cod..
..The VoIP Hurricane Net, Hurricane Watch Net and WX4NHC, the Amateur Radio Station at the National Hurricane Center, all activated Thursday Evening through Friday Morning for Hurricane Arthur’s landfall in Eastern North Carolina and will likely activate formally once again for Hurricane Arthur for direct impacts on Nova Scotia Canada where the Canadian Hurricane Centre is also likely to be active as well..

Thursday represented the largest severe weather outbreak of the 2014 summer season with many pockets of wind damage, hail, flooding and lightning damage. Those with damage and/or hail photos may send them as a reply to this message or to pics@nsradio.org and the photos will be shared with the media, emergency management and the National Weather Service. The Local Storm Report from Thursday’s severe weather outbreak appears below:

Attention now turns to Hurricane Arthur and his interaction with the cold front that caused Thursday’s Severe Weather Outbreak. This cold front will finally make its way through Southern New England late tonight and Saturday Morning. This front will interact with Hurricane Arthur and cause a heavy rainfall event especially in Eastern Massachusetts and Rhode Island but also in a more localized way in western and central parts of the region. At 950 AM, radar showed outer rain bands of Hurricane Arthur affecting parts of Southeast Massachusetts, Block Island and Long Island moving north-northeastward while a band of rainfall associated with the cold front is over Southwest New Hampshire, Western Massachusetts and Eastern New York. The interaction of these systems is likely to cause the potential for heavy rainfall this afternoon and evening over Eastern Massachusetts and Rhode Island. The headlines depict the Flash Flood Watches over the area and expected rainfall amounts.

There will be a bit of wind impacts over extreme Southeast New England but the main threat as stated all week has been the threat for heavy rainfall and flood/flash flooding with Hurricane Arthur and the interaction of the Cold Front. Nonetheless, portions of the Outer Cape and Nantucket Island will receive a period of strong to damaging winds to tropical storm force Friday Evening into early Saturday Morning as well as some pockets of coastal storm surge flooding. Winds will be out of the northeast so north and east facing locations will face the greatest risk for pockets of moderate storm surge coastal flooding. Wind intensity will be much like a conventional nor’easter over this area so isolated tree and wire damage and power outages are possible. Winds will be less as you move away from Cape Cod and Nantucket and the bigger issue across much of the area is the potential for flooding from heavy rainfall. The headlines depict the main wind threat in the Tropical Storm Warning area from Woods Hole to Provincetown including Nantucket Island Massachusetts.

The VoIP Hurricane Net, Hurricane Watch Net and WX4NHC, the Amateur Radio Station at the National Hurricane Center, all activated Thursday Evening through Friday Morning for Hurricane Arthur’s landfall in Eastern North Carolina and will likely activate formally once again for Hurricane Arthur for direct impacts on Nova Scotia Canada where the Canadian Hurricane Centre is also likely to be active as well.
