Hello to all..

..The following is the first 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 18 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..2021 Field Day weekend will mostly be dry, warm and humid but has potential shower and thunderstorm risks in isolated to scattered locations particularly on Sunday. The potential for severe weather on Sunday is low but frequent lightning is a threat near any scattered thunderstorms that can develop..
..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. Due to lingering COVID-19 concerns, Amateur Radio Field Day across Southern New England will be a bit different with somewhat less Field Day sites than normal in the region but more sites than 2020. Those that are up and running may have some level of COVID-19 protocols in place. There will be some Amateur Radio Field Day operations operating at home and not at field locations. Amateur Radio Field Day resource information is listed below..
..SKYWARN Self-Activation will monitor conditions throughout Field Day weekend as needed..

Here are some links to information on these Amateur Radio Field Day Sites from across the region understanding there could be some COVID-19 protocols in place depending on the field day sites:

Amateur Radio Field Day Information: http://www.arrl.org/field-day
Amateur Radio Field Day National Locator: http://www.arrl.org/field-day-locator
Eastern Massachusetts Field Day Home Page: https://ema.arrl.org/field-day/
Eastern Massachusetts Field Day Directory: http://ema.arrl.org/field_day/

While most of the weekend will be dry, there will be scattered showers and thunderstorm chances particularly on Sunday. Warm and humid conditions will prevail in the region with highs in the 80s with a few locations reaching around 90 degrees possibly on Sunday and lows in the 60s to lower 70s. It will be important for Amateur Radio Field Day sites operating outside to drink plenty of liquids and to stay cool as the temperatures this weekend will be a precursor to a potential heat wave to start the new work week. Coordination messages will be sent throughout the weekend to monitor the potential for any thunderstorms on the Sunday of Amateur Radio Field Day weekend.

Below are links to the NWS Boston/Norton Hazardous Weather Outlook and NWS Boston/Norton Enhanced Hazardous Weather Outlook:

Amateur Radio Field Day sites are 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:
https://wx1box.org/southern-new-england-skywarn-frequency-list/

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 and rain gear for any showers and thunderstorms 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 in isolated to scattered locations over the course of Friday and the weekend, 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:

Hello to all…

..Isolated to scattered strong to severe thunderstorms are possible this Tuesday Afternoon and Evening particularly across Rhode Island and Southeast Massachusetts. Strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding are the main threats. This potential is contingent on the overlap of instability with sufficiently strong wind shear profiles ahead of an approaching cold front which will bring cooler and less humid conditions to the region..
..SKYWARN Self-Activation will monitor the severe weather potential for this Tuesday Afternoon and Evening in Southeast New England. This will be the only coordination message as we shift into monitoring the severe weather potential. Below is the NWS Boston/Norton Area Forecast Discussion and Enhanced Hazardous Weather Outlook..

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible late Monday Afternoon and Evening across Western Massachusetts along and west of the CT River Valley and Northwest Connecticut. Timeframe is between 5-10 PM Monday with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding as the main threats. There have been no changes to the outlook since yesterday..
..The Storm Prediction Center (SPC) has placed Western Massachusetts and Northwest Connecticut along and west of the Connecticut River Valley in a marginal risk for severe weather for late Monday Afternoon and Evening..
..SKYWARN Self-Activation will monitor the severe weather potential for Monday late Afternoon and Evening..

A pre-frontal trough will move through New York and Northern New England and then spread into Southern New England during Monday in the late afternoon and evening and bring the potential for isolated to scattered strong to severe thunderstorms over portions of Western New England. The headlines depict the current thinking and are unchanged from yesterday. Key factors include:

1.) Timing of the pre-frontal trough as earlier timing into Western New England would increase the severe weather potential there but later timing would reduce the potential.
2.) Wind shear profiles are favorable which may compensate for lower instability if current timing in the late afternoon/early evening holds.

SKYWARN Self-Activation will monitor the severe weather potential for Monday late afternoon and evening. This will be the last coordination message as we shift into operations mode.

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible mid-to-late Saturday Afternoon and Evening across areas of Southern New England along and south of the Mass Pike though areas north of the Mass Pike should continue to monitor with a timeframe of after 3-4 PM til 12 AM Saturday with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding as the main threats.
..The Storm Prediction Center (SPC) has focused the marginal risk for severe weather for Saturday to areas along and south of the Mass Pike with the latest update but areas north of the Mass Pike should continue to monitor..
..SKYWARN Self-Activation will monitor the severe weather potential for Saturday late Afternoon and Evening..

An impulse in the atmosphere will move into Southern New England mid to late Saturday Afternoon into Saturday Evening with the potential for isolated to scattered strong to severe thunderstorms. The headlines depict the current thinking. Key factors include:

1.) Amount of available instability since the impulse will move through past peak heating.
2.) Wind shear profiles are favorable which may compensate for lower instability if current timing in the late afternoon/early evening holds.
3.) If timing of the impulse is earlier than currently expected allowing better overlap of higher instability with strong wind shear and the impulse acting as a trigger in the atmosphere.
4.) Amount of available moisture in the atmosphere and the moisture return as we get toward later afternoon and evening. Areas of north of the Mass Pike have drier dewpoints but areas along and south of the Mass Pike has higher dewpoints and moisture available which is why the marginal risk for severe weather is focused on that area.

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

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms possible to likely across Southern New England particularly Central and Eastern New England away from the immediate coast this Tuesday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy rainfall with urban to poor drainage flooding are the main threats..
..The Storm Prediction Center (SPC) has placed much of Southern New England in a marginal risk for severe weather as more heating and destabilization is occurring away from the immediate coast leading to higher instability than originally forecasted. This coupled with strong winds aloft and cooling in the atmosphere will allow for some strong to severe thunderstorm development and the timeframe for severe weather potential for 2-8 PM Tuesday..
..SKYWARN Self-Activation is likely to monitor this severe weather potential for this Tuesday Afternoon and Evening. This will be the only coordination message as we shift into operations mode. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and SPC Day-1 Convective Outlook..
