Thunderstorm Outlook for Day 1
Scattered Thunderstorms producing locally heavy downpours.
Regional Impacts
Central and Southern Labrador: scattered thunderstorms giving localised 25mm
Convective Discussion
Upper Low over the Quebec North Shore will slowly rotate north today. Mid-level instability northeast of the system continues to produce elevated CB/ACB’s . CLDN shows the persistence of these lightning strikes over the boundary between Quebec and Labrador. These storms should reach the Trans-Labrador Hwy this afternoon but the flash rate should dimininsh.
In NB, the cloud cover extends from the low to southern NB and therefore will be a limiting factor for the vertical development of convective cloud. Temperature of 20 / Dewpoint of 12 was enough to produce SBCAPE of about 300 J/kg but the airmass dries quickly in the mid-levels as indicated by the 12z CAR sounding.
Thunderstorm Outlook for Saturday
Slight risk of non-severe thunderstorms over parts of NB
