Regional Impacts
NS, Cape Breton, eastern PEI: Thundershowers and showers this afternoon.
Western Labrador: Weak unorganized convection and showers tomorrow near the upper low center.
Convective Discussion
A frontal feature is transiting Nova Scotia now bringing showers and weak thundershowers to many areas of the province. This forcing will move offshore later today. Environmental shear has degraded quite a bit since the front cut thru NB earlier. Cape Breton (nearer the low center) still has 15-20kts of 0-6k to work with early this aft. This is where the most lightning activity is expected in the next 2hrs. Pwats are 35 in the model and 32 on actual soundings. However, cells are moving at a good pace, leading to only 5-10mm in the heaviest pockets of rain. Alerts are not likely today. Tomorrow is calmer behind the front in the less humid and cooler air mass. Labrador may see a few lightning strikes tomorrow simply due to proximity to the low feature. Severe weather is not expected.
