2015 Canada Spring Out­look: Cold Start Fore­cast for On­tario, Que­bec

Stanstead Journal - - SPORTS -

Ac­cuWeather re­ports a late start to spring can be ex­pected across a large por­tion of On­tario and Que­bec, in­clud­ing Toronto and Mon­treal, as a chilly, north­west­erly flow of air is fore­cast to dom­i­nate. In ad­di­tion, ice cov­er­age is av­er­ag­ing 15-20 per­cent above nor­mal on the Great Lakes. The com­bi­na­tion of this higher-than-nor­mal ice ex­tent and the spring weather pat­tern will keep the lakes colder than nor­mal through the spring, which will have an added cool­ing ef­fect on ar­eas di­rectly down­wind of the lakes

More per­sis­tent west­erly steer­ing winds off the warmer-than-nor­mal eastern Pa­cific Ocean will de­liver more storms than usual to west-cen­tral Bri­tish Columbia dur­ing the sea­son.

Th­ese per­sis­tent winds will also de­flect much of the lin­ger­ing win­ter cold away from west­ern Canada dur­ing early spring.

The stormy pat­tern across At­lantic Canada this win­ter will likely con­tinue into at least the first half of spring with the po­ten­tial for late-sea­son snow­storms in cities such as Saint John, New Brunswick, and Char­lot­te­town, Prince Ed­ward Is­land, and heavy rain far­ther south and east in places such as Hal­i­fax, Nova Sco­tia, and St. John’s, New­found­land, and Labrador.

The com­bi­na­tion of a stormy pat­tern and deep snow­pack across New Brunswick and north­ern Nova Sco­tia will in­crease the flood threat across the re­gion dur­ing the first half of spring.

On the flip side, snow­fall has been well be­low nor­mal across south­ern Man­i­toba so far this win­ter and the lack of snow­pack will re­duce the risk of ma­jor spring river flood­ing in and around Win­nipeg, Man­i­toba.

Far­ther west in Saskatchewan, the risk of spring flood­ing will be higher due to a more ex­ten­sive snow pack and the ex­pec­ta­tion of above-nor­mal spring rain­fall in south­ern parts of the Prov­ince from Regina to the U.S. bor­der.
