Regional Impacts
Labrador today…
Southern New Brunswick, Fundy, northern Nova Scotia and PEI and into the Gulf of Saint Lawrence… Thunderstorms and heavy downpours with 30 + mm of rain possible in some areas tonight.
Convective Discussion
For Labrador weak updrafts could be sufficient to generate an isolated thunderstorm over a fairly large area. No severe weather is expected although stronger wind gusts can be expected in thunderstorms.
Tonight conditions may come together with moisture convergence ahead of a weak trough that will move over the area. With precipatable water values exceeding 50mm and most unstable Cape values near 500 j/kg locally heavy rain is possible where deeper convection occurs. Local rainfall rates of 30-40mm/hr are possible and radar should monitored for stronger cells moving through this evening and into the overnight hours.
