Regional Impacts
Newfoundland and Labrador… Airmass thunderstorms giving 15-20mm.
Nova Scotia and New Brunswick… Airmass thunderstorms giving 20 to 25mm with small hail possible.
Convective Discussion
With relatively low moisture and minimal wind shear available organised convection will be fairly limited. The is potential for some airmass thunderstorm with mixed layer CAPE values around 500 J/kg and most unstable CAPE values over 1000 J/kg for western NB, less so in other areas. Most probable areas for convection to initiate will be over southwest NS and Western NB. Down draft potential is high enough to provide some gusty winds near thunderstorms but it is not expected to reach near warning level, however the situation will be monitored through the day for changes. There is a slight possibility that training or back building thunderstorms could develop increasing the rainfall potential.
Over the next few days the potential for thunderstorms will slowly but gradually diminish
