Regional Impacts
Today: Offshore embedded TS risk this morning continues with frontal departure from last nights L pressure system. No other convection forecast with invading smoke from the north, and building ridge.
Tonight, into Monday morning: Ridge over Maritimes. Nil sig weather. Frost risk under clear skies.
Monday afternoon: Maritimes are capped and stable. Non-severe thundershowers are possible in western and central Labrador along a W-E translating trof line.
Tuesday: Ridge erodes late in the day with an advancing disturbance/cooling column aloft and causing a risk of -TS. Details will be better forecast in next 24hrs.
Convective Discussion
Nil sig convective weather across Nfld/Maritimes Day1, Night1, Day 2. Thundershowers expected to pop up along a ridge-riding trof line across Labrador on Monday. Hazards would simply be moderate rainfall as forward progression of trigger is slow. Tuesday brings a broad destabilization with cooling aloft throughout the day – leading to skinny Cape again and moderate shear. Single cell storms are forecast for western NB/mainland NS by evening.
