Convective discussion:
Risk of non-severe thundershowers over southeastern Nfld. and much of New Brunswick.
Technical Discussion:
In New Brunswick cape values of up to 750 J/kg however very low shear values (ie. No high or low level jets in the proximity). High freezing level of 12K feet will reduce any hail size.
A convective temperature of 24 degrees is required however there is currently considerable low level cloud in NW New Brunswick limiting solar heating. No real trigger to initiate convection either. If/when convection is realized the main threat is localized rainfall due to the light flow. Precipital water is 30-40 mm.
Regional Impacts:
New Brunswick: Possible thundershowers. Possible high local rainfall amounts in heavier showers.
Nova Scotia and Prince Edward Island: Nil
Newfoundland: Chance of a thundershower.
Labrador: Nil.
