Hello to all..
..Potential for Heavy Rainfall, urban/poor drainage and possibly small river/stream flooding from thunderstorms later Thursday Afternoon through Friday Morning across much of Southern New England. An Isolated Strong to Severe Thunderstorm threat with damaging winds and large hail also is possible depending on amount of heating particularly over interior Western New England..
..A Flash Flood Watch is now in effect for Thursday Afternoon into Friday Afternoon for all of the NWS Taunton Coverage Area except for Cape Cod and the Islands..
..SKYWARN Activation with Ops at NWS Taunton are possible later Thursday Afternoon and possibly Friday Morning depending on how the flash flood threat evolves as well as any severe weather potential..
On Wednesday, the strong to severe thunderstorm potential was not realized as the impulse in the atmosphere was displaced by the area that was most unstable from daytime heating. A few thunderstorms with heavy rainfall did occur but none were strong to severe.
For Thursday Afternoon into Friday Afternoon, the main concern is for flash flooding. At 730 AM, Doppler Radar showed an area of rain and embedded thunderstorms over Eastern Pennsylvania moving northeast to east-northeastward. This should arrive in Southern New England later Thursday Afternoon and tonight bringing the potential for heavy rainfall and embedded thunderstorms. A Flash Flood Watch is in effect for the entire NWS Taunton coverage area except for Cape Cod and the Islands from Thursday Afternoon to Friday Afternoon for potential rainfall around 2″ with higher amounts in any thunderstorms that may track over the same area. The flood potential would be for urban/poor drainage areas and smaller rivers and streams.
Isolated strong to severe thunderstorms are possible as a secondary threat across interior Western New England with damaging winds and hail as the primary threats. Satellite imagery shows cloud cover over much of Southern New England, however, their is clearing noted over New York State and the mid-atlantic ahead of the area of rain and embedded thunderstorms in Eastern Pennsylvania tracking northeast to east-northeastward. It is possible that if that clearing can work into portions of interior Western New England that a few strong to severe thunderstorms could occur before evolving into more of a flood to flash flood threat. This will be monitored as we get into this afternoon.
SKYWARN Activation with Ops at NWS Taunton are possible later Thursday Afternoon and possibly Friday Morning depending on how the flash flood threat evolves and any severe weather potential. This will be the only complete coordination message on today’s weather. A shortened coordination message will be issued if time allows and Ops at NWS Taunton are initiated.
