Regional Impacts
Some weak thunderstorms are likely to develop late today over northern New Brunswick. This evening and tonight the risk will spread through the gulf impacting western Newfoundland by the morning..
Convective Discussion
The atmosphere will continue to destabilize later today and through tonight as a cold upper trough makes its way through the region. Overall the amount of moisture has diminished over the last few days but steepening lase rate should be sufficient to generate stronger updrafts overnight and tomorrow morning for the eastern gulf waters and tomorrow afternoon for parts of Newfoundland.
For tomorrow deep shear and CAPE will continue to increase as the upper trough approaches, with ~40 knots of 0-6km shear and ~1000 j/kg. Organised convection is possible with a low probability of supercell formation. Strong wind gusts, 25mm + rain and small hail is possible.
