Cooler air likely to favor the East for a significant part of June

Latest signs point toward a large-scale trough setting up across eastern Canada starting around June 5. Usually when that happens, we end up seeing a ridge building across the West.
What this means is warmer and drier air dominating across the West, while several cool fronts come into the East/Atlantic Canada with opportunities for some rain or thunderstorms, at least through mid-June.
