Convective Discussion
The focus has moved from the Maritimes to Newfoundland today with precipitable water values near 50mm and most unstable cape values ~1000 j/kg. Thunderstorm structure should be similar to what New Brunswick saw yesterday with several reports of nearly 25mm in less than an hour although unreported amounts were likely higher. There is some potential for cluster or multicell storms to form giving decent gusts, however it may be a challenge to trigger the stronger storms but it does seem that the cloud is breaking up over the island and solar insolation could increase through the afternoon.
