This cold pattern is quite persistent for the time of year, but it’s no stranger for 2016; as the same pattern was around for most of April and half of May.  The west and the central part of the country is hot, and the east is cold once again.  The difference being the cold upper level northwest flow is centered more over northern Quebec, so Eastern Ontario will feel its effects a lot more than Southwestern Ontario.  Temperatures will stay in the 17c – 21c range for Eastern Ontario likely right through to June 14th – 15th, possibly out to June 18th, while Southern Ontario will feature a couple rounds of warmer and humid air coming through.

Here is the GEFS temperature for next Wednesday:

There are signs from the GFS as well as the Euro models that warmer air will make its way around June 18th and temperatures will likely stay normal to slightly above normal for the rest of June. And at no surprise…drier!  If you are looking for more rain there is potential Saturday as a cold front sweeps through (the rain will mostly be around the GTA and east to Kingston, but mostly stop short of Eastern Ontario).  Any other moisture will likely have to come from a passing thundershowers, as I don’t see any more major rain makers coming currently (aside from scattered convection activity).  Dry conditions continue to persist:
