Thunderstorm Outlook for TODAY – Tuesday, Aug 10, 2021
Regional Impacts
Isolated severe thunderstorms are possible over northern NB this afternoon and into this evening.
Convective Discussion
The limiting factor today remains to be shear. The sfc moisture is present for good buoyancy, but any storm that develops will have minimal forward motion, and unable to slant its structure significantly. And so, the biggest hazard is heavy rainfall and a downburst gust of wind.
Thunderstorm Outlook for TOMORROW – Wednesday, Aug 11, 2021
Regional Impacts
Isolated severe thunderstorms are possible over western portions of Labrador. Elsewhere, non-severe thunderstorms are possible.
Convective Discussion
An advancing trof will trigger thunderstorms in Quebec and into adjacent Atlantic regions. Greatest hazard with these storms is heavy rainfall. Shear is slightly better at 10-20Kts, and Pwats remain near 35-45mm.
