Convective Outlook Valid for Today and Tomorrow

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.

Regional Impacts - None

 

Convective Discussion – There are currently a few strikes associated with a trough of low pressure over Quebec.  This trough will move across New Brunswick tonight bringing a slight risk of thundershowers for New Brunswick and western PEI.  Cloud top cooling could help with convective development but severe thunderstorms are not expected.

Regional Impacts

 

Isolated thunderstorms with locally heavy downpours and gusty winds.

 

Convective Discussion

 

Thunderstorms can be expected for eastern New Brunswick… PEI… Northern Nova Scotia and into the Gulf of Saint Lawrence. There is some upper support with strong shear, however with low CAPE updrafts should remain weak. However given the favourable dynamics and warm water in the Gulf it is possible that some storms could become organised. Although unlikely strong surface sings could develop in some of these storms.
