Regional Impacts
Slight risk of a thundershower tonight for NB.
Risk of a late day thunderstorm for W/NW NB Sunday giving gusty winds and heavy downpours. Slight risk of a thundershower Sunday evening for far southwestern NS.
Convective Discussion
Quiet today right across the board as the MRTMS and NL are under the influence of a ridge of high pressure. A frontal trough will give showers to most of Labrador but no lightning is expected. The same frontal trough will slide down over NB tonight giving just the slight risk of a thundershower overnight and early Sunday with the aid of cloud top cooling. Sunday will give the risk of a late day thunderstorm to W/NW NB as a secondary frontal trough rapidly swings in upstream from Quebec. This front could give some strong wind gusts and locally brief heavy downpours. The aforementioned trough impacting NB tonight will give some showers and risk of thundershowers to NS Sunday night.
