Storm Coordination Message #2 – Friday Night 5/28/21-Saturday Morning 5/29/21 Heavy Rainfall/Strong Wind Gust Potential

May 28, 2021 Rob Macedo

Hello to all…

..Strong storm system to bring a soaking rainfall of 1-2.5″ of rain with isolated higher amounts to all of Southern New England and strong wind gusts of 40-50 MPH to Southeast New England. Updated coordination message includes a time extension of the Wind Advisory for the islands, updated rainfall map and a statement on some exposed shore road coastal flooding in localized areas..
..A Wind Advisory is in effect from 2 AM to 7 PM Saturday for Marthas Vineyard and Nantucket and is now expanded to include Barnstable County – Cape Cod for sustained winds of 25-35 MPH with gusts to 50 MPH. Wind gusts of 35-45 MPH are likely across Southeast Coastal New England from roughly Plymouth Massachusetts to Westerly Rhode Island. With fully leaved trees, these winds will cause isolated to scattered pockets of tree and wire damage and isolated power outages..
..Up to half foot of water on most exposed coastal roads could occur in Eastern Massachusetts, Cape Cod and the Islands during the overnight high tide late Friday Night into Saturday Morning..
..SKYWARN Self-Activation will monitor for rainfall reports, measured wind gusts of 40 MPH or greater and wind damage reports throughout this storm system. Additional rainfall is expected Sunday Afternoon into Monday Morning. This will be the last coordination message unless a significant update to the situation occurs and time allows for an update.

Special Announcement: WX4NHC On-Air Test Saturday 5/29/21 from 9 AM-5 PM EDT – WX4NHC Will Be on Echolink WX_TALK/IRLP 9219 – 5/29/21 4-5 PM EDT

May 28, 2021 Rob Macedo

Hello to all…

WX4NHC, the Amateur Radio station at the National Hurricane Center, will be active with its on air-test Saturday 5/29/21 from 9 AM-5 PM EDT (1300-2100z). They will be on the *WX_TALK* Echolink conference node: 7203/IRLP 9219 reflector system from 4-5 PM EDT (2000-2100 UTC) Saturday 5/29/21. A link to the WX4NHC On-Air Test Announcement as well as an announcement regarding the virtual Amateur Radio Workshop tied to the National Hurricane Conference from the ARRL and Assistant WX4NHC Coordinator, WD4R-Julio Ripoll, is listed below:

To all radio amateurs

SB SPCL ARL ARLX006
ARLX006 Annual WX4NHC On-the-Air Station Test Set for Saturday, May
29

The annual WX4NHC station on-the-air test will be held on Saturday,
May 29, 1300 – 2100 UTC. The WX4NHC operators plan to be working
remotely again this year as the National Hurricane Center plans to
maintain all CDC COVID-19 pandemic protocols until the end of 2021.
The yearly exercise takes place just ahead of the official start of
the Atlantic Hurricane Season, June 1 – November 30. Assistant
WX4NHC Coordinator Julio Ripoll, WD4R, said the event offers an
opportunity for radio amateurs worldwide to exercise the sorts of
communication capabilities available during severe weather.

“We will be making brief contacts on many frequencies and modes,
exchanging signal reports and basic weather data (sunny, rain,
temperature, etc.) with any station in any location,” Ripoll said.

Participating stations may use HF, VHF, UHF, APRS, and Winlink, with
WX4NHC HF activity centering on the Hurricane Watch Net frequencies
of 14.325 MHz and 7.268 MHz, depending on propagation, and will
operate elsewhere as conditions dictate. WX4NHC will also
participate in the VoIP Hurricane Net, 2000 – 2100 UTC.

As for the upcoming hurricane season, Ripoll said, “Even if you are
not directly affected by a hurricane situation, please volunteer to
monitor and relay reports; just one report can make a difference and
help save a life!”

In conjunction with the National Hurricane Conference next month,
the traditional Amateur Radio Workshop sessions will be held
virtually on Tuesday, June 15, 10:30 AM – 12 PM EDT and 1:30 – 5 PM
EDT. The sessions will be moderated by Rob Macedo, KD1CY, Director
of Operations, VoIP Hurricane Net, with Ripoll.

To access the Zoom meeting check-in, use the meeting ID 844 9788
6921, and the passcode 565708.

Severe Weather Coordination Message #3 – Wednesday 5/26/21 Severe Weather Potential

May 26, 2021 Rob Macedo

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are likely late Wednesday Afternoon and Evening between 5-10 PM. Strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding are the main threats with an isolated tornado or two as a secondary threat.
..The Storm Prediction Center (SPC) has continued Western Massachusetts and Northwest Connecticut in a slight risk for severe weather and North-Central Connecticut, Northwest Rhode Island and Central and Northeast Massachusetts in a marginal risk for severe weather for Wednesday..
..SKYWARN Self-Activation will monitor the severe weather potential for late Wednesday Afternoon and Evening..

Wednesday will feature warm and humid conditions as winds turn to the southwest with a pre-frontal trough and cold front moving into Southern New England Wednesday Afternoon and Wednesday Night. This will set the stage for isolated to scattered strong to severe thunderstorms in portions of Western and Central New England. The headlines depict the current thinking and conditions are more favorable than we saw on Sunday where no strong to severe thunderstorms developed. Key factors include:

1.) Timing of the cold front through portions of Southern New England. The timing now is expected to be a bit past peak heating after 5-6 PM which could reduce the threat a bit particularly for an isolated tornado or two but with strong wind shear and full sun for the entire today, there remains the threat for some organized isolated to scattered strong to severe thunderstorms in the region.
2.) Amount of instability in the region with sunshine allowing for destabilization is in place in the region so this factor is met.
3.) Wind shear profiles will be favorable for some level of organization to any strong to severe thunderstorms that can develop with the possibility for rotating storms and a secondary threat for an isolated tornado or two but given the timing of the front, these conditions will have to overcome some lessening instability past peak heating of the day.

SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon and Evening. This will be the last coordination message as we shift into operations mode.

Severe Weather Coordination Message #2 – Sunday 5/23/21 Severe Weather Potential

May 23, 2021 Rob Macedo

Hello to all…

..Isolated to Scattered Strong to Severe thunderstorms are possible Sunday Afternoon and Evening anytime between about 2-8 PM EDT. Strong to damaging winds, hail, frequent lighting and heavy downpours with minor urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) continue much of Southern New England in a marginal risk for severe weather for Sunday.
..In addition, portions of Eastern New England and marine areas could see strong straightline winds for a brief period of time even without thunderstorms present as the frontal passage goes through with brief wind gusts of 40-45 MPH with isolated higher gusts. This could cause isolated pockets of tree and wire damage and isolated power outages in land areas and cause issues for small boaters out on the water in marine areas..
..SKYWARN Self-Activation will monitor the severe weather potential for Sunday Afternoon through Evening..

Warm and humid conditions will be prevalent across the region Sunday with a strong cold front pushing through the region. This will setup the potential for isolated to scattered strong to severe thunderstorms. The headlines depict the current thinking. Key factors remain as follows:

1.) Amount of instability that is generated from daytime heating, available moisture and moisture convergence as a cold front sweeps through the area. This will be key in determining storm coverage.
2.) Timing of the cold front through peak heating of the day.
3.) Ability of the forcing of the cold front and favorably strong winds aloft to compensate if instability and moisture levels are limited or the timing of the cold front is not near the time of peak heating.
4.) Even if few thunderstorms develop, the conditions along and ahead of a cold front may allow for a brief period of strong wind gusts particularly in Eastern New England and marine areas and this may cause isolated pockets of tree and wire damage and could be an issue for any small boaters out in marine areas and will be monitored.

SKYWARN Self-Activation will monitor the severe weather potential for Sunday Afternoon through Evening. This will be the last coordination message as we shift into operations mode. Below is the NWS Boston/Norton Area Forecast Discussion, Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
