Convective discussion:
A cold front will sweep across the region today. Embedded thundershowers with frequent lightning and downpours are expected ahead and near the front.
Technical Discussion:
A cold front with embedded thundershowers will track across Atlantic Canada today and tonight. Abundant cloud near and ahead of the front is limiting Cape values to below 500 J/kg. Precipital water values of 40-50 mm are producing torrential downpours. Frequent lightning is also a concern. A low level southwesterly jet of 60 knots may give gusty winds in thundershowers.
Regional Impacts:
New Brunswick, Nova Scotia and Prince Edward Island: Heavy downpours and frequent lightning. Gusty southwest winds.
Newfoundland: Chance of thundershowers.
Labrador: Nil
