Changes are Afoot
Snow will begin across the Rockies from east of Pine Pass to Kakwa today as a cold front on the leading edge of a ridge of high pressure centred over the Northwest Territories makes its way south. The weaker nature of this cold front will limit the extend of snowfall to near and east of the peaks, into Alberta today. As it progresses southward, some spillover into the Rocky Mountain Trench is expected.
Over southern B.C., a final day of elevated freezing levels and warm temperatures under the influence of an upper ridge of high pressure. A weak low pressure system will squeak in from the southwest on Wednesday bringing an end to the warm and dry spell over southern B.C.
A second low pressure system will make its presence known on Friday with another round of snow. Northern and central B.C. will remain clear and cool.
An upper ridge of high pressure over southern B.C. will give one last round of warm and dry conditions. Moisture squeezed in between this upper ridge over B.C. and a very large upper low over Hudson Bay will produce snow over the Rockies today and tomorrow.
A weak upper low near Haida Gwaii this morning will move offshore and transform in a broad upper trough as the week progresses, bringing moisture to southern B.C., ending the stretch of dry weather.
