Convective Discussion...
A fairly quiet day is expected today, with a few areas that may see a couple lightning strikes this afternoon. First, a weak shortwave moving across New Brunswick this morning will pass over PEI this afternoon, triggering some showers along the Cobequids in central Nova Scotia. Higher dewpoints and a slight upslope enhancement are expected to aid in convection here today. These showers will have a slight chance to produce a lightning strike or two as they move east, however very little shear and minimal CAPE will likely inhibit the lifespan of these cells.
A second weak shortwave moving southeast along the Labrador coast is producing some scattered showers today across south-central Labrador. Some stronger low and mid-level jets over this region highlight the risk for some of these showers to produce some lightning strikes early this afternoon, though this risk remains low.
Tomorrow, a weakening cold front moving across Atlantic Canada may trigger some thundershowers in parts of New Brunswick and Labrador, but at this time the risk is low.
