Amateur Radio Field Day/Severe Weather Coordination Message #2 – June 24th, 2011 8 AM Post

June 24, 2011 Rob Macedo Leave a comment

Hello to all..

..The following is the second in a series of messages on Amateur Radio Field Day Weekend. Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend. Many locations can be visited by the public and Amateur Radio Field Day can be a form of outreach to Ham and non-Ham Operators. It is also noted that several states have given proclamations to Amateur Radio/Ham Radio Operators for either an ‘Amateur Radio Week’ during the month of June or ‘Amateur Radio Month’ for this month. It is both a fun/preparatory event for Ham Radio Operators for Emergency Communications scenarios..
..As have been done over the past 10 plus years, this will be the second in a series of Severe Weather/Amateur Radio Field Day Coordination Messages to pass instructions to Amateur Radio Field Day sites on what to do if threatening weather approaches and to have Field Day sites guard their SKYWARN repeaters as required if threatening weather approaches..
..Field Day Weekend is still expected to bring unsettled weather to the region with periods of showers and thunderstorms possible on both Friday Afternoon and Evening and Saturday Afternoon and Evening though a total washout is not expected. At this time, Sunday is still expected to be dry. For Field Day sites setting up during Friday Afternoon and Evening, there is also the potential across Western Massachusetts and Northern Connecticut of isolated to scattered strong to severe thunderstorms with damaging winds, large hail and urban/poor drainage flooding as the primary threats. Outside of this area, thunderstorms with lightning are possible towards this afternoon and evening. On Saturday, the threat of severe weather could expand to much of interior Southern New England with damaging winds, large hail, urban/poor drainage flooding and lightning all threats during the afternoon and evening if sufficient heating and destablization can occur..
..This Week is also Lightning Awareness Week and safety information on lightning gets propagated during this period and has coincidentally coincided with Amateur Radio Field Day weekend and that information is included in this coordination message..
..SKYWARN Activation with Ops at NWS Taunton are possible on Friday Afternoon and Evening as well as Saturday Afternoon and Evening. SKYWARN monitoring for even non-severe thunderstorms will be done over the weekend to protect Amateur Radio Field Day sites as best as possible..

There are a large number of Amateur Radio Field Day sites across the NWS Taunton County Warning Area and adjacent NWS County Warning Areas. Here are some links to information on these Amateur Radio Field Day Sites from across the region and links to the Amateur Radio Week Proclamation given by the Governor of Massachusetts for Amateur Radio Field Day 2011:

Field Day Info from the Central Massachusetts Amateur Radio Association (CMARA) as provided by NE1R-Tom Carrigan:
The Central Massachusetts Amateur Radio Association, (W1BIM) celebrating
75 years of existance, will be participating in Field Day (rain or
shine) on the athletic field of David Prouty High School on Route 9 in
Spencer, MA. The public is cordially invited to visit between 2:00 pm
Saturday and about 12:00 noon on Sunday. Amateur Radio operators are
welcome to come and pitch-in, even if they have not yet joined the
CMARA. Access is by a driveway at the left side of the parking area on
Route 9.

Field Day Info from the Charlestown, RI EOC Ham Radio Team as provided by W1JPZ-John Zabriskie:
The Charlestown RI EOC Ham Team will be operating around the clock from Ninigret Park in Charlestown, RI ( the old Charlestown Naval Air Station ). The public is invited to visit from 1:00pm to 4:00pm on Saturday and from 10:00am to 2:00pm on Sunday. Of course we would be glad to show the operation to any one who shows up at any time during park hours. The park closes at Sunset and re-opens at Sunrise to the general public.

If there is additional Amateur Radio Field Day information that you would like to appear in these coordination messages, please contact me and I will add it to this section of the Amateur Radio Field Day Coordination Message.

On Friday, any Amateur Radio Field Day sites doing setup will see cloudy conditions with some breaks of sun possible over Western Massachusetts and Northern Connecticut. If these breaks of sun occur and a weak wave of low pressure is able to move into the region, isolated to scattered strong to severe thunderstorms could potentially develop by afternoon with damaging winds, large hail and urban and poor drainage flooding as the primary threats. Outside of this area, thunderstorms with lightning are possible in the region. Temperatures will remain in the 60s but if any breaks of sunshine develop, temperatures could hit the lower 70s in those areas. The cool marine flow should protect most to possibly all areas from severe weather but areas out to the west may get some heating and if that occurs that may allow for an isolated severe thunderstorm or two and garden variety thunderstorms with lightning could be scattered across much of the region despite the cool marine flow. Any thunderstorms that do develop will have the attendant risk of lightning which is a danger to all Amateur Radio Field Day sites setting up during Friday Afternoon and evening regardless of whether thunderstorms become severe. The threat will be monitored with SKYWARN Activation and Ops at NWS Taunton possible during Friday Afternoon and Evening. A shortened message will be sent if time allows and Ops at NWS Taunton are initiated for this afternoon and evening.

As we get into Saturday, conditions will remain unsettled though the entire day is not expected to be a washout. The warm front which has been stalled out to the west of the region will move through and there should be a bit more sunshine then the past few days and temperatures into the 70s. While this sounds like good news, if enough sunshine develops, the atmosphere will cool aloft as a cold front approaches the region and wind shear profiles will be fairly strong. If enough sun and destablization occurs, isolated to scattered severe thunderstorms, perhaps even a squall line of strong to severe thunderstorms may develop by afternoon and evening affecting much of interior Southern New England. At the coast, thunderstorms with a lightning risk would be possible later Saturday Afternoon and Evening. This will be watched very closely. Again, any severe threat will depend on any sun and heating that could destablize the atmosphere and that will be better understood in future forecasts. Non-severe thunderstorms could be the main threat if heating doesn’t occur which pose a lightning safety risk to Field Day sites. SKYWARN Activation with Ops at NWS Taunton will be possible again Saturday Afternoon into Saturday Evening. As we get into late Saturday Night into Sunday, drier conditions will return to the area and the threat for thunderstorms and severe weather will have passed though isolated showers cannot be ruled out.

Amateur Radio Field Day sites setting up on Friday and active on Saturday should use caution and keep an eye to the sky and monitor their local SKYWARN Repeater, NOAA Weather Radio or weather information via Internet and media resources to guard against safety issues if thunderstorms, even if they are non-severe, occur in the region due to the potential lightning risk on radio equipment and antennas. Proper grouding of antennas is essential to help reduce any risk from lightning.

Below is the NWS Taunton Hazardous Weather Outlook:

SKYWARN Activation with Ops at NWS Taunton is possible on Friday Afternoon into the evening as well as Saturday Afternoon and Evening. A shortened coordination message will be issued if time allows and Ops at NWS Taunton are initiated on Friday. SKYWARN monitoring for non-severe thunderstorms and their lightning risk will be done throughout the weekend to protect Amateur Radio Field Day sites as required.

Also, as stated previously, remember that non-severe thunderstorms can pose a threat to Amateur Radio Field Day sites due to the threat of lightning. Please keep this in mind if you have an outdoor Field Day site. This week is Lightning Awareness Week and the National Weather Service in Taunton has posted information on Lightning Safety Awareness Week. See links below for this information:

Again, Field Day sites are encouraged to bring a NOAA All-Hazards Weather Radio and a dedicated Ham Radio that can monitor their local SKYWARN Frequency for their area or if they have mobile Internet capability, that is also a way to monitor for weather information if thunderstorms, even that are non-severe, approach your area. With Mobile Internet capability, utilizing Echolink to monitor the New England Reflector system on Echolink Conference Node: 9123/IRLP 9123 would be helpful. Please see the link below for the latest SKYWARN Frequency information for the region:
