Convective Discussion
Clearing skies are expected today in the wake of a low pressure system exiting Nova Scotia. Dew points will remain in the mid teens this afternoon over areas of Nova Scotia and eastern Prince Edward Island. This combined with some local convergence and afternoon temperatures near 25 could lead to a risk of non-severe thundershowers. Dry bulb temperature of 25 and a dew point temperature of 15 will break the cap and give CAPE values near 200 J/kg. So the necessary values required to break the cap are also at the maximum of the range of temperatures expected for today. Over Labrador a risk of thundershowers are expected south of the forecast areas.
