Thunderstorm Outlook for Day 1
Regional Impacts - None
Convective Discussion – There are currently a few strikes associated with a trough of low pressure over Quebec. This trough will move across New Brunswick tonight bringing a slight risk of thundershowers for New Brunswick and western PEI. Cloud top cooling could help with convective development but severe thunderstorms are not expected.

Thunderstorm Outlook for Day 2
Regional Impacts - None
Convective Discussion
A trough of low pressure will track across New Brunswick Wednesday night bringing a slight risk of thundershowers.
Regional Impacts
Isolated thunderstorms with locally heavy downpours and gusty winds.
Convective Discussion
Thunderstorms can be expected for eastern New Brunswick… PEI… Northern Nova Scotia and into the Gulf of Saint Lawrence. There is some upper support with strong shear, however with low CAPE updrafts should remain weak. However given the favourable dynamics and warm water in the Gulf it is possible that some storms could become organised. Although unlikely strong surface sings could develop in some of these storms.
Thunderstorm Outlook for Day 1
Thunderstorm Outlook for Day 2
Regional Impacts
Locally heavy downpours possible over southern New Brunswick and Nova Scotia.
Convective Discussion
In general weak updrafts can be expected today as warm advection aloft will tend to keep the local atmospheric conditions relatively stable. However we will continue to see ample moisture with upwards of 50mm of precipatable water available for southern areas and generally more than 40mm across the Maritimes. Embedded thunderstorms could be sufficient to generate local flash flooding this evening for southwest Nova Scotia and locally heavy downpours elsewhere. The threat of severe weather is minimal today, however conditions for tomorrow could be somewhat more hazardous depending on the remaining moisture and timing of the upper trough that will move over the region.
