The unusual cool pattern for June continues.   The upper air cyclonic flow and the dip in the jet stream relaxes on Saturday, allowing a warm front to approach Saturday.  It currently appears that much of the dynamics and moisture will lift to our north.  Much of Saturday will be dry.

For Sunday, low pressure over eastern Canada intensifies, and the associated upper air flow again becomes cyclonic, following a cold front passage.  Unsettled and cooler weather is likely again for Sunday.  A mix of clouds and sun with a possible shower and windy, as upper air vorticities rotate around the Canadian surface low.    Again, mostly dry.

This cool weather, unstable, upper air cyclonic pattern really continues on and off for much of June, with short-lived warm ups.  The medium-long range forecast for the next two weeks or so doesn’t show much of a Bermuda high pattern typical of late spring and summer.  Expect cool weather, mostly dry but with instability allowing shower-formation for the next few weeks.
