Regional Impacts
NL… Scattered severe thunderstorms possible across southern Labrador today. Main hazards are strong wind gusts of 70 to 90 km/h, heavy downpours of 25 to 35 mm/h, and 1 to 2 cm hail.
NS/NB/PEI… None.
Convective Discussion…
After a busy couple of days in the Maritimes, the focus shifts to southern Labrador today, where an upper trough with some diffluent upper level flow brings the risk for some scattered severe thunderstorms this afternoon. MLCAPE values are forecast to rise upwards of 1500 J/kg today over southeastern Labrador, leaving plenty of fuel for thunderstorms to work with. In addition, bulk shear values of 25 to 35 knots in the same area increases the potential for some of these storms to become severe. Shear is expected to be fairly linear, however some curvature of the low level winds is possible early on in the afternoon. As such, a discrete supercell or two cannot be ruled out early this afternoon, before storms become more linear later on. The main hazards today will be torrential downpours of 25 to 35 mm/h, strong wind gusts of 70 to 90 km/h, and 1 to 2 cm hail.
