Over the course of Labor Day and into Tuesday with the warm and humid air remaining in place, it will set the stage for the potential of additional isolated to scattered strong to severe thunderstorm development with strong winds, hail and flash flooding as potential threats. The timing of these thunderstorms are uncertain as well as magnitude. Some computer models push the threat more into Monday Night and Tuesday while other computer models have the threat over much of Monday and Tuesday across the region. This will make for difficulty in timing potential formal SKYWARN Activation and Ops at NWS Taunton and the utilization of SKYWARN Self-Activation to cover things as they unfold as what occurred on Sunday.

SKYWARN Activation with Ops at NWS Taunton are possible to likely during portions of Labor Day and into Tuesday. SKYWARN Self-Activation may also be utilized given the uncertainty of the magnitude and timing of any flash flood and/or severe weather potential. Another coordination Message will be posted late Monday Morning or early Monday Afternoon depending on how storms evolve overnight and into Monday Morning.
