A complicated and winter storm at the end of the season threatens some difficult trips to areas of Ontario and Quebec until Tuesday. The messy system will start to start the week on Monday, with the opportunity for some snow that accumulates and can be shoveled – not a small feat for this end of April. Winter travel weather warnings cover parts of southern Ontario, warning of reduced visibility and smooth surfaces such as roads and sidewalks. More about the schedule and the expected effects, below.
MONDAY WITH THURSDAY: CLEARED WINTER SNOW SNOW IN CENTRAL CANADA
A dynamic pattern sweeping the eastern half of Canada and the United States will lead to an intricate and wintery landscape for Ontario and Quebec over the next two days. A difficult storm route and a slight temperature slope will mean the difference between heavy rain and snow that can be shoveled for almost anyone between Windsor and Quebec City. The system began pushing into southern Ontario on Monday afternoon, bringing increasing cloud cover during the day with rain falling from west to east across the area. Lower altitudes and areas near the lake will see a mixture of rain and snowflakes, with the possibility of snow accumulating on elevated or grassy surfaces. However, in areas with higher altitudes, including the Niagara Falls, limit temperatures will fall below freezing, allowing more significant accumulations of 5-10 cm to accumulate. “The most significant impact on traffic in the greater Toronto area will likely be Monday afternoon, with wet roads and the risk of icy ramps and crossings,” warns Michael Carter, a meteorologist at The Weather Network. “The snow that will get stuck will be more likely for travelers heading north and west moving to higher altitudes.” The Environment and Climate Change Agency of Canada (ECCC) has issued a winter travel guide for parts of the south, with the threat of significantly reduced visibility in heavy snowfall and snowfall rates peaking up to 3 cm per hour. Drivers are advised to adapt to changing road conditions and to be especially careful when walking or driving in affected areas. Thunderstorms and strong winds will remain until Tuesday, leading to periods of low visibility and changing conditions. A stronger, secondary low will develop later Monday, reaching deeper humidity and bringing more significant impact to parts of Quebec by Tuesday. Montreal can see 5-10 inches of snowfall, with the highest ground outside the St. Louis Valley. Lawrence to have 10-20 + inches by Tuesday. This will be accompanied by stormy winds, which will lead to periods of dangerous travel conditions that resemble winter. There may even be some ice balls in the extreme parts of eastern Quebec on Tuesday afternoon. Rainfall will begin to fall in the province from west to east until night and night. Prolonged light snowfall will be observed in southern Ontario on Tuesday and is expected to subside in the morning. Sporadic rains may prevail in areas of the cottage and eastern areas in the afternoon, before weakening at night. Looking to the future, another system could affect the area until Thursday morning before temperatures are moderate towards the end of the week. We are looking forward to a few days of warmer weather in the last days of April, but a cooler pattern is expected for early May, as an exclusion pattern is expected to recreate.
