Convective Outlook Valid for Today and Tomorrow

Regional Impacts

 

Today

Southern LAB/western NL: scattered elevated thunderstorms possible.

NS: slight risk of an isolated thunderstorm for eastern mainland.

 

Tonight

Southeastern LAB/NL: isolated thunderstorms possible

 

Saturday

Western LAB/northern NB/northeastern NL: isolated thunderstorms possible.

 

Convective Discussion

A much quieter day compared to the severe weather in NW NB yesterday. Some ongoing elevated thunderstorms associated with the upper trough moving over the GLFSTLAWR will likely be on and off this afternoon and into tonight as it slopwly progresses eastward over southern LAB and NL. Only some locally heavy downpours are expected but could be some gusty winds as well in some of the stronger cells. That same trough will likely give some isolated stuff overnight and into Saturday morning for parts of Newfoundland. And a slight risk of a thunderstorm this afternoon for eastern mainland NS close to that 500mb trough.

 

On Saturday a new 500 mb trough/short wave will approach from Quebec increasing the chance for thunderstorms across western LAB and far northwestern NB. Also a slight chance for an isolated cell for northeastern NL close to that first departing trough.
