Convective Discussion
Over eastern Labrador today, a tropical moisture feed is expected ahead of a broad upper low and surface trough. This same system gave copious amounts of rain and gusty winds to parts of New Brunswick and Prince Edward Island yesterday. CAPE values near 1000 J/kg and effective shear of 30 to 40 knots are expected. While wind gusts and hail are possible, it will be training thunderstorms giving copious amounts of rain that is the main concern. Due to much lower CAPE values, the trough will give just a chance of thundershowers for parts of Newfoundland and eastern Nova Scotia. On Sunday an approaching trough will give a chance of thundershowers for northern New Brunswick and southeastern Labrador.
