Clouds and few showers expected today across PEI..

Thursday, August 16th 6:50am.. A cold front oriented NE-SW is currently crossing the island and is now located just east of Charlottetown. Cloud showers and possible thundershowers are associated with the frontal passage. Cooler air will now flood in behind the front on NW winds which will result in clouds and few showers lingering into tomorrow morning. High pressure will build in from the west cresting over the island Friday morning. Clouds will then begin to increase later Friday as low pressure approaches from the west with rain developing before dawn on Saturday. The low is expected to track across central Maine then south of NS Saturday evening. High pressure then dominates the region from Sunday through Wednesday with sunshine but need to watch a potential small area of low pressure passing offshore east of NS on Tuesday.

Cloud and showers possible in the cool unstable air behind the front today and tonight with a slight chance of a thundershower. Dry for tomorrow then rain at times heavy begins before dawn on Saturday ending near midnight. Rainfall amounts with this system could be significant with 20-30mms possible.
