Convective Discussion
There are two features over Atlantic Canada today. An approaching low pressure system over central Quebec will give a risk of surface based thundershowers over extreme western Labrador this afternoon. There is currently some relatively cloud free skies well ahead of the low which will aid in the convection. The second feature is an elevated area of warm air (TROWL) which is moving across western Newfoundland. A very slight risk of thundershowers are possible there. It is such a slight risk that it is not noted in the graphic below.
