Prairie Forecast Update: Manitoba in retrograde

If you have followed my forecasts over the years, you will know that the term retrograde is almost always associated with bad weather. Well, an area of low pressure about to come on shore over Eastern Canada is expected to retrograde, or move westward, ending up around James Bay by Monday or Tuesday.

How will this impact the weather across the Prairies? For those of you in Alberta and most of Saskatchewan, it won’t. The upper ridge will continue to build bringing sunny and seasonably warm weather.

For Manitoba, the counterclockwise rotation of the low will result in a northeasterly flow off Hudson Bay for the remainder of this forecast period. This means most days will see a mix of sun and clouds, there might be the odd shower, and temperatures will be on the cool side. Expect daytime highs in the 7 to 10 C range with overnight lows in the 0 to +3 C range.
