The culprit for the unseasonably cold weather is a slow moving upper level trough of low pressure sliding across the Great Lakes. The cool, wet weather will continue into Tuesday, before high pressure returns midweek.
It could be much worse, snow is falling once again across portions of Newfoundland. Winter is long enough in this country without June snow. St John's was only -1C (30F) this morning, with snow falling. Some locations measured as much as 5cm, with 10cm expected along the northwest coast. The normal high in St. John's is 15C (59F) for early June, however the forecast high for Monday is only 3C (38F). Other portions of Atlantic Canada fared no better, dipping to the freezing point last evening, with many locations reporting frost. Over a dozen record lows were set, including -2.2C (28F) in Edmundston, New Brunswick, -4.2C (24F) in Churchill Falls and -2.3C (28F) in Truro, Nova Scotia.
