Severe Weather & Amateur Radio Field Day Weekend Coordination Message #3 – Saturday 6/23/18-Sunday 6/24/18 Weather Outlook/Severe Weather Potential

June 23, 2018 Rob Macedo Leave a comment

Hello to all..

..The following is the third in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 15 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..Saturday will feature showers at times widespread over portions of Southern New England with heavier rainfall and urban and the potential of urban and poor drainage flooding as well as an attendant lightning risk later Saturday into Saturday Night though there will also be dry periods as well particularly in interior Southern New England. As we move into Sunday, the morning currently looks dry but if the warm front makes it through the region and clearing occurs behind the warm front then the potential for isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lightning and heavy rainfall on Sunday Afternoon/Evening potentially when Amateur Radio Field Day sites are breaking down stations and wrapping up for this year’s event. Weekend weather will continue to be monitored closely..
..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 Day or Amateur Radio Week’ during the month of June or an ‘Amateur Radio Month’ for this month. It is both a fun/preparatory event for Ham Radio Operators for Emergency Communications scenarios..
..SKYWARN Activation with Ops at NWS Taunton are possible on Saturday afternoon into early evening for any potential for thunderstorms, heavier downpours with possible urban and poor drainage flooding and the attendant lightning risk towards later afternoon/evening and will be based on radar trends. SKYWARN Activation with Ops at NWS Boston/Norton are possible Sunday Afternoon/Evening for isolated to scattered strong to severe thunderstorm potential..

There are a large number of Amateur Radio Field Day sites across the NWS Boston/Norton Coverage Area and adjacent NWS Coverage Areas. Here are some links to information on these Amateur Radio Field Day Sites from across the region:

The commonwealth of Massachusetts has declared this week to be Amateur Radio Week and Governor Baker has proclaimed Sunday June 24th, 2018 Amateur Radio Day in honor of the ARRL Field Day event. The details can be seen at the following links:

As of 920 AM Saturday, Doppler Radar showed a large area of showers with moderate rainfall to heavy rainfall across Southeast Coastal New England. There has been no lightning with this activity. Elsewhere across Southern New England, spottier light rain showers are developing over Western New England and to a lesser extent in Central New England. All activity is moving Northeast to North-Northeast. At this time current trends indicate most of interior Southern New England will be dry for the next several hours with a few passing showers barring development of more showers over the interior. For Southeast New England, steady rainfall in showers with moderate to heavy rainfall will continue for the next several hours before it moves northeast outside of the area. As we get closer to later Saturday Afternoon into evening, showers could again become more numerous with heavier rainfall especially across the Southeast New England but potentially in other parts of the area. There will also be the threat of isolated thunderstorms as well. Severe weather is not expected but the showers and heavier downpours and isolated thunderstorms could pose an urban and poor drainage flooding threat as well as an attendant lightning hazard. This may require monitoring from NWS Boston/Norton to guard field day sites and field flooding reports in isolated to scattered areas. If this occurred, we would likely put in operations at NWS towards the later afternoon and evening.

For Sunday, showers and any isolated thunderstorms and downpours should end during the overnight hours and offer a dry Sunday Morning. As we get into the afternoon and evening hours provided the warm front moves through the region as forecasted and there is sufficient clearing for heating and destabilization, there will be the potential for isolated to scattered strong to severe thunderstorms across the coverage area with strong to damaging winds, hail, frequent lightning and heavy rainfall as Field Day ends and takedown of equipment occurs. This will bear watching as we get model runs later on Saturday to discern the severe weather potential further for Sunday.

SKYWARN Activation with Ops at NWS Taunton are possible later Saturday afternoon into early evening for any potential for thunderstorms, heavier downpours with possible urban and poor drainage flooding and the attendant lightning risk towards later afternoon/evening and will be based on radar trends. SKYWARN Activation with Ops at NWS Boston/Norton are possible Sunday Afternoon/Evening for isolated to scattered strong to severe thunderstorm potential.

Amateur Radio Field Day sites are still encouraged to bring a NOAA All-Hazards Weather Radio, monitor various cell phone weather apps where Amateur Operators may have those available and have a dedicated Ham Radio that can monitor their local SKYWARN Frequency for their area as a best safety and preparedness practice. Also sites that have mobile Internet capability can utilize that capability as a way to monitor for weather information. With Mobile Internet capability, utilizing Echolink to monitor the New England Reflector system on Echolink Conference *NEW-ENG3* Node: 9123/IRLP 9123 would be helpful as well. Please see the link below for the latest SKYWARN Frequency information for the region:

During setup and takedown of Amateur Radio Field Day sites and even while operating, be sure to drink plenty of fluids and eat accordingly. Also having a jacket or sweatshirt during evenings as conditions cool etc. may also be useful while operating this year’s Field Day. The link below features information on Heat Safety:

Given the threat for thunderstorms particularly on Sunday, lightning is a threat to any and all Amateur Radio Field Day sites. Remember your lightning safety tips and details on lightning safety can be seen at the following link:

The next Amateur Radio Field Day coordination message will be posted by 1000 PM Saturday Evening.
