Convective Outlook Valid for Today and Tomorrow

Thunderstorm Outlook for Today

 

Regional Impacts

Isolated non-severe thunderstorms are expected today in parts of northern New Brunswick.

 

Convective Discussion

In a moderate southwest flow, and dew points building throughout today, there will be a few isolated non-severe thunderstorms. Pockets of heavy rain would be the biggest threat with any cell that develops. Storms will be short lived however with not much shear at play in the atmosphere.

 

 

Thunderstorm Outlook for Tuesday

 

Regional Impacts

Isolated non-severe thunderstorms are possible in Western Labrador and parts of New Brunswick.

 

Convective Discussion

Surface based CAPE (500-1000J/kg) and shear (30+kTs) are more favourable for single cell/multi cell storms to develop on Tuesday under the passage of a cold front. With PWATs of 30+mm, heavy rain is again the risk under a cell that may develop.
