Convective Discussion:
A warm and humid air mass prevails throughout the region. A 30kt southwesterly LLJ and a supportive vorticity centre is giving thundershowers over areas of Newfoundland today. Generally MLCAPE values range from 500-1000J/kg however a clear lack of a trigger or a supportive upper jet should allow the main threat to be downpours. PWAT values near 40 mm maintain the downpour threat that has been in existence for the last few days in areas where the cells are training or slow moving.
