Storm Coordination Message #1 – Saturday 5/20/23-Early Sunday Morning 5/21/23 Heavy Rainfall/Urban/Poor Drainage Flooding Potential

Hello to all…

..Beneficial rainfall expected for Southern New England later Saturday Morning through early Sunday Morning as a storm system from the south interacts with a cold front but amounts maybe heavy enough for portions of Southern New England where urban and poor drainage flooding could occur particularly if amounts of 3-4″ of rain or more fall over urban and poor drainage areas. Wind Gusts of 30-40 MPH are possible in any heavier downpours later Saturday Afternoon and Saturday Night..
..SKYWARN Self-Activation will monitor for any rain gauge, flooding, measure wind gusts 40 MPH or greater, wind damage reports later Saturday Morning through early Sunday Morning. This will be the only coordination message on this situation unless a significant upgrade occurs and time allows for an update. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and Rainfall Map..
