Regional Impacts
Today: Embedded convection along a trundling trof line from Avalon down to slope waters. No severe hazards forecast. Rain and scattered lightning expected.
Tonight: No thunderstorms forecast.
Tomorrow: Risk of thunderstorms in southern and western Labrador. Additional risk of organized convection across NB. These storms could bring gusty winds and heavy downpours.
Convective Discussion
Conditions are fairly stable behind dominant cold frontal forcing today/tonight. Ahead of the front (and near the triple point near Stephenville, NL) activity continues. Rainfall is the biggest hazard under organized clusters. Significant mid-level smoke is entering into the Maritimes from the NW under the building ridge. This may act as enhanced CIN to the TS forecast for Sunday. But, if it doesn’t – multicell thunderstorms are possible in NB in the afternoon and evening. Effective shear is over 30 kts and bases will be decently high, giving a wind gust risk.
