Thunderstorm Outlook for Day 1
Isolated tstorms producing local downpours today for New Brunswick and parts of coastal NS with slight risk of severe thunderstorms producing heavy downpours.
Regional Impacts
Risk of localised heavy downpours for New Brunswick and parts of coastal Nova Scotia.
Risk of non severe thundershowers for southern Newfoundland.
Convective Discussion
Isolated thunderstorms a possibility today across New Brunswick and parts of coastal Nova Scotia. Generally conditions are unfavourable for severe t-storm formation. The area is not dynamically in a favourable location, low level max winds are only around 20 kts, precipitable water is only around 25 mm, low level Td’s are around 12C and vertical motions look to be inhibited at around 500mb. However, some coastal convergence along eastern NB and parts of NS could push parcels above the 500mb cap which could result in local heavy downpours especially since they will be slow moving or stationary. Also, forecasts highs are around 26 degrees. If actual highs go a few degrees warmer, then it may be enough thermodynamic lift to get past the 500 mb cap and produce some local heavy downpours.
