Clipper season

November is upon us and, in southern Manitoba, that means clipper season. The main frontal zone sits, as it tends to do this time of year, from northwest to southeast across the prairies. Any little upper impulses that ripple along the front tend to be fairly dry, but 2 to 5 cm of snow is a good bet with any of them.

Add in the fact that parts of the lakes are still ice-free, sprinkle with some cold air moving over them, and even without the frontal zone you can get cloud and flurries in the lee of the lakes.

I suppose it's better than the -30s we'll inevitably see later this winter.
