Severe Weather Coordination Message #2 – Friday Afternoon & Evening 6/2/23 – Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to possibly Severe Thunderstorms remain possible Friday Afternoon and Evening across Southern New England between 12-8 PM. Strong to damaging winds, small hail, frequent lightning and heavy downpours with urban and poor drainage flooding are the primary threats..
..SKYWARN Self-Activation will monitor the severe weather potential for Friday Afternoon and Evening..

A backdoor cold front is still expected to sweep into Southern New England Friday Afternoon and Evening. As it moves through the region, this will be the trigger for isolated to scattered strong to possibly severe thunderstorms for Friday Afternoon and Evening. The headlines depict the current thinking. Key factors include:

1.) Ability for low wind shear values to be compensated by magnitude of instability and the wide temperature/dewpoint spread that may allow for and enhance the strong wind potential despite weak wind shear aloft.
2.) The structure of the cold front and its ability to tap into instability in the atmosphere for thunderstorm development
3.) The actual magnitude of the instability that can develop ahead of the front
4.) Thunderstorms that form are likely to be slow moving and could result in localized urban and poor drainage flooding

SKYWARN Self-Activtion will monitor the severe weather potential for Friday Afternoon and Evening. This will be the last coordination message for this severe weather potential unless a significant upgrade to the situation occurs and time allows for an update.
