Severe Weather Coordination Message #2 – Thursday 5/23/24 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible late Thursday Morning through Thursday Evening through around 8 PM Thursday. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the primary threats..
..The Storm Prediction Center (SPC) has continued most of Southern New England in a marginal risk of severe weather with the greatest potential now along and south of the Mass Pike and could include some coastal areas but all parts of the marginal risk area should monitor conditions today..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets remain possible Thursday for the severe weather potential..

A pre-frontal trough and cold front will swing through Southern New England Thursday setting the stage for potential strong to severe thunderstorm development. The headlines depict the current thinking. Key factors include:

1.) Amount of cloud cover which given current shower and thunderstorm activity over the area could limit the potential a bit but there still could be isolated strong to severe thunderstorms in the area.
2.) Timing of the cold front is a bit earlier in the day which means heating won’t be as maximized per earlier thinking but some storms have been severe in portions of Southeast New York and Southwest Connecticut despite the earlier timing so this will still bear watching.
3.) The coverage of strong to severe thunderstorms in the region will depend on the above two factors.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible Thursday for the severe weather potential. This will be the last coordination message as we shift into operations mode.

Severe Weather Coordination Message #1 – Thursday Afternoon & Evening 5/23/24 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible Thursday Afternoon and Evening anytime between 12-8 PM Thursday. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the primary threats. The Storm Prediction Center (SPC) has placed nearly all of Southern New England in a marginal risk of severe weather with the greatest potential in interior Southern New England from Boston to Providence north and west..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible Thursday for the severe weather potential..

A pre-frontal trough and cold front will swing through Southern New England Thursday setting the stage for potential strong to severe thunderstorm development. The headlines depict the current thinking. Key factors include:

1.) Amount of cloud cover which is currently expected to be low enough for strong to severe thunderstorm development
2.) Timing of the cold front to maximize the heating of the day
3.) The coverage of strong to severe thunderstorms in the region will depend on the above two factors

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible Thursday for the severe weather potential. Another coordination message will be posted by 11 AM Thursday Morning.

Severe Weather Coordination Message #1 – Wednesday Afternoon/Evening 5/8/24 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible across much of Southern New England this Wednesday Afternoon and Evening with the greatest threat in Western and Central Massachusetts and Northern Connecticut. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding are the primary threats. Threat timeframe is roughly from around 1-8 PM this Wednesday Afternoon and Evening..
..The Storm Prediction Center (SPC) has placed all of Southern New England in a marginal risk for severe weather. The greatest threat within the marginal risk is across Western and Central Massachusetts and Northern Connecticut but the whole risk area particularly interior Southern New England should monitor the potential with hail being the greatest risk east of Central Massachusetts and Northern Connecticut..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets will occur as required based on any warnings issued or reports meeting the SKYWARN reporting criteria are received. Pictures of hail/wind damage etc. can be sent as a reply to this email, via our WX1BOX Facebook/Twitter feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

An area of showers and isolated thunderstorms associated with the warm front moved through the area this morning. Satellite imagery indicates areas of clearing that will potentially allow for heating and destabilization moving into Connecticut and Western Massachusetts. This will allow for the development of isolated to scattered strong to severe thunderstorms in this area. The headlines depict the current thinking. Key factors include:

1.) Amount of heating and instability overlapping cooling aloft and sufficient wind shear profiles for strong to severe thunderstorm development.
2.) Main threat area is Western and Central Massachusetts and Northern Connecticut where storms will have the best chance to become surface based but east of this area, as storms become elevated could have the risk for some hail particularly in interior locations.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets will occur as required based on any warnings issued or reports meeting the SKYWARN reporting criteria are received. Pictures of hail/wind damage etc. can be sent as a reply to this email, via our WX1BOX Facebook/Twitter feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated.
