Regional Impacts
Nova Scotia, PEI and southern New Brunswick: likely some elevated convection this afternoon and through the night associated with an upper level area of low pressure over New England. Heavy downpours are the only threat.
Newfoundland: a weak trough of low pressure may give an isolated thundershower to southeastern regions through the course of the day.
Labrador: nil.
Convective Discussion
The aforementioned upper area of low pressure has produced quite a bit of elevated convection to the east/southeast where the area of divergence is maximized. The sun has been warming the tops some this morning which has lead to a weakening in the lightning but things will continue gradually progress northeastward through the course of the day. There could be some locally heavy downpours later today and tonight. The PWAT is close to 40 mm. There is a slight risk of an embedded thundershower across portions of southeastern Newfoundland in association with a weak trough of low pressure. OTWZ nothing to talk about for the rest of the region.
Thunderstorm Outlook for Day 1
Convective Discussion
There will remain a risk of thundershowers over portions of SE NL and the MRTMS associated with the upper area of low pressure. Also a frontal trough will be moving southeastward across Labrador that may trigger a couple thunderstorms.
Thunderstorm Outlook for Day 2
