The Tuesday Evening NWS Boston/Norton Local Storm Report can be seen below:
NWS Boston/Norton Local Storm Report:
Severe weather potential continues to increase for Wednesday and this has prompted an upgrade in the severe weather outlook to Enhanced in parts of our coverage area as indicated in the headlines. A cold front will be approaching the region and with the intense heat and humidity in place and increasing winds aloft, it will set the stage for a greater risk of strong to severe thunderstorm development along with a greater coverage of strong to severe thunderstorms across Southern New England. Key items for Wednesday will be how quickly the cold front gets into or close enough to the region to provide a trigger for thunderstorm development and the overlap of the stronger winds aloft with high instability over the region from intense heating and humidity through the day. Also it is presumed any lingering cloud cover from overnight convection in Eastern New York will not prevent expected strong heating through the day and this will be monitored. The main threat appears to be clusters or lines of strong to severe thunderstorms with damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding to flash flooding in the area.
SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon and Evening. Another coordination message will be posted by 11 AM Wednesday Morning.
