Convective Discussion
In general the potential for thunderstorm development is quite low across the region today. There is a slight chance of TCU’s developing just behind the through while low level moisture is still present. There is a slight chance that TCU’s over western Newfoundland could develop into weak thunderstorms. There will likely be some cooling aloft which will aid in destabilizing the atmosphere, this along with some solar insulation and convergence in the general trough area could generate some weaker updrafts. The risk may continue into the evening along a secondary surface trough.
