Cold wet start to the work week in Montreal

After a perfect weekend, Monday dawned, rainy, windy and cold across southern Quebec. Montreal dropped from 24C (76F) late Sunday evening to 9C (49F) by morning. Combined with a brisk northeast wind of 50km/h, it was downright miserable. The cool weather was accompanied by steady rain, with 27mm falling as of midday Monday. The moisture is welcome, as the area did have a precipitation deficit since the start of May. However, I could do without the cold weather, as summer is short enough.

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.

June Snow!
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.
