A strong storm system will bring very warm temperatures to Southern New England with the potential for a period of heavy rain and strong to damaging winds to the region. The headlines depict current thinking. Key factors remain:

1.) Strong winds aloft mixing down to the surface. This would be amplified if temperatures remained unusually warm Thursday Night into Friday Morning in the upper 50s to lower 60s or if a fine line of convective showers and thunderstorms develop.
2.) Wind advisories are now posted for Western and northern parts of Southern New England due to wind gusts of up to 55 MPH and the isolated wind damage potential it brings.
3.) Rainfall is not expected to bring widespread flooding but typical urban and poor drainage flooding from heavy rainfall and snow melt could occur as the system moves through the area.

SKYWARN Self-Activation will monitor for measured wind gusts 40 MPH or greater, wind damage, and any rain gauge reports 1″ or more Thursday Night into Friday Morning. This will be the last coordination message on this storm event as we shift into operations mode unless a significant update to the situation occurs and time allows for an update.
