Regional Impacts
NB.. A few isolated showers this afternoon will bring a very slight risk of thunderstorms with a few lightning strikes.
NS..A non zero chance of a thunderstorm, with a slight chance of a shower, no impacts.
Elsewhere.. No thunderstorms expected.
Convective Discussion.. Today marks the first day of the summer severe weather desk at the ASPC and it seems we will be off to a slow start. As is often the case this time of the year low moisture in boundary layer will be a limiting factor with surface Dewpoint Temperatures remaining in the single digits through the day. However there will be some instability as an upper trough tracks across New Brunswick with most unstable CAPE values likely below 250 J/kg. The upper trough will move through rather quickly so the potential will be short lived as we settle into calm weather for the next couple of days. No significant hazards are expected today but a few lightning strikes are possible with the showers as they move through the Maritimes.
Thunderstorm Outlook for Today..
