Convective discussion:
Risk of non-severe thundershowers over Atlantic coastal regions of Nova Scotia and central/Newfoundland this afternoon and evening.
Technical Discussion:
A cold front with an associated low pressure system is sweeping across Atlantic Canada today. Very moist tropical air (dew points 20 degrees plus) ahead of the front get replaced by much drier and stable air in its wake. Morning soundings are not showing much CAPE ahead of the front so just a risk of a thundershower is expected ahead of this fast moving feature. The thundershower risk is surface based for Nova Scotia and embedded for Newfoundland. Lots of clouds already in Newfoundland ahead of the approaching low pressure system.
Regional Impacts:
New Brunswick: Nil.
Nova Scotia: Risk of non-severe thundershowers.
Prince Edward Island: Nil
Newfoundland: Risk of non-severe thundershowers.
Labrador: Nil.
