Convective Discussion

Nil sig weather convection wise across the Atlantic domain until tomorrow late day. An advancing trof in central and northern Quebec may bring a lightning strike or 2 embedded in some shower activity late day tomorrow in parts of western Labrador. The bigger weather system to watch in next 3 days in Erin. Detailed hurricane forecast information can be found on weather.gc.ca/hurricane. Thunderstorms associated with this system will creep into the marine domain on Friday (into Saturday). They may push orange limits for rain and wind gusts near the southern border of our Canadian domain.
