Well it happened again…June frost!  As was the case yesterday, each province got a little taste of it.

The coldest official temperature I found was in Collegeville NS just after 5:30 this morning; there the mercury dropped to -1.7;  Collegeville is about 35 km SW of Antigonish.  North East Margaree came in a close second with a morning reading of -1.4.  Over on the Island, the official thermometer in Dover PEI was showing a cold -0.5 at 5 am.  That same temperature was recorded in Saint-Quentin New Brunswick.  For a second morning in a row it was as frosty morning in Upper Stewiacke with a sunrise temperature of -0.1

It’s important to remember that these official temperatures are taken 1.5 m above the ground.  Cold air is heavy and settles close to the ground, so it was most likely even cooler than these temperature indicate.  There could also have been frost in other regions where official temperatures were just above freezing.

Will this be the last one?  I would say so!  There is no risk of frost in the Maritimes tonight.  The upper air circulation has shifted to the southwest.  An advancing warm front will bring rain tomorrow followed by some clearing Sunday afternoon with warm temperatures for that Father’s Day BBQ!

Happy Father’s Day to all the wonderful dads out there!
