Thunderstorm Outlook for Today, Tonight and tomorrow
Regional Impacts for today (see below for tomorrow):
The trough that produced some thunderstorms over the Maritimes yesterday is now over the southern marine district. Some higher gusts are possible with these thunderstorms but not likely to exceed 30 kts.
Very slight chance of thundershowers over southern NB this afternoon with locally heavy showers.
Convective Discussion:
Now with the cold front mostly passed for the Atlantic region, conditions are not favourable for thunderstorm development. The lower levels will realize some instability this afternoon so likely some Cu could develop over southern NB but mid levels are stable so the vertical extent of the Cu will likely be capped. A sea breeze front could develop over southern NB this afternoon which will act as a kicker for Cu so maybe low chance of isolated TCU could develop along this front which could bring local heavy showers. The chance of TCU ends this evening as insolation diminishes.
