Unsettled weather to continue in Montreal through May

Snow covers spring flowers in Northern Vermont on Tuesday morning. Rare May snow fell across portions of southern Quebec and northern New England on Tuesday, as a late season Nor'easter moved along the Atlantic coast circulating cold, moist air into the region. Below normal temperatures are expected to persist this week in Montreal. (AccuWeather)

Low pressure moving along the Atlantic coast continues to circulate cold, moist air down the Saint Lawrence Valley. Overnight, another 14mm of rain fell in Montreal, bringing our monthly total up over 60mm. The Ottawa River and Lake of Two Mountains remain well above flood stage. The lake level at Sainte-Anne-de-Bellevue was 24.36 metres on Tuesday. The lake should remain stable this week, however major flooding continues to occur along the Ottawa River.

The cold and dreary weather pattern across Ontario and southern Quebec is expected to continue this week, with near or below normal temperatures expected for the foreseeable future. The forecast high on Tuesday in Montreal was expected to be just shy of 10C (50F), this is well below the normal of 19C (66F) for the date. Several locations in northern New England, New Brunswick and southeastern Quebec even had measurable snow overnight. Killington, Vermont reported 15 to 20cm of new snow on the summit. The cold weather is even impacting the northeastern US, New York's Central Park recorded its coldest May 13 ever on Monday, with a high of only 48F. The previous record was 49F set in 1914.

The weather is actually warmer in northern Quebec today, with Eastmain on James Bay the warmest location in the province at 2pm Tuesday, at 20C (68F). Moosonee in northern Ontario is the warmest location in the country at 22C (72F).

Unfortunately the unsettled weather is expected to continue well into next week, with perhaps a decent day or two somewhere in between. An active weather pattern will produce plenty of opportunities for additional rainfall through the end of the month.
