Convective Discussion…
A quiet day is in store for most of Atlantic Canada today as a ridge of high pressure settles into the central Maritimes. Over Labrador, a weakly unstable environment may be enough to trigger some non-severe pop up thundershowers today. The 12Z Goose Bay sounding this morning showed some relatively weak lapse rates, though a cool airmass aloft will only require convective temperatures of around 16 or 17 degrees. However a lack of moisture (PWATs <15 mm) and effective shear (10 to 20 knots) will limit the intensity and lifespan of any storms that do fire today.
Tomorrow a similar environment is expected over southeastern Labrador, where the risk once again exists for some non-severe pop up thundershowers.
