Thunderstorm Outlook for Day 1
Regional Impacts:
Risk of isolated thunderstorms this evening over northwestern New Brunswick with possible heavy showers and strong wind gusts.
Convective Discussion:
Instability over the Maritimes is quite low as a thermal ridge sits over the area at issue time. The thermal ridge tracks east through the day and so instability increases slightly over the area this evening. Prog tephis only showing around 100 J/kg this evening which is quite insignificant so only a risk of isolated thundershowers is expected. The highest threat if thundershowers develop is local heavy rainfall as low level moisture is moderate. Strong wind gusts below warning criteria is also possible.
