Ridge will triumph over Great Lakes, Ontario swerves two storms

The most potent Colorado low of the season walloped Wyoming and the northern Plains with over half a metre of snow this past weekend, shutting down thousands of kilometres of interstates.

When people in Central and Eastern Canada hear “Colorado low” or “Texas low,” their attention is usually obtained, and for good reason. The storm track for these systems more often than not results in a placement over the upper or lower Great Lakes, respectively.

This particular system is quite the opposite. A dominant high over northern Ontario helped to dictate the fate of the storm, which ultimately blocked the storm from reaching the Great Lakes, resulting in the storm dissolving before reaching Lake Michigan.

NEXT SYSTEM FROM TEXAS WILL ALSO BE A MISS

An upper low over the U.S. southwest will spawn another storm east of the Rockies on Tuesday. The difference with this setup is the storm will form over the Texas Panhandle (giving it the Texas low designation) and there will no longer be a blocking high over the Great Lakes.

Through Wednesday, the storm will siphon moisture and warmth from the Gulf of Mexico as it takes its preferred path toward Lake Erie. At this time, another ridge will quickly develop over northern Ontario.

So, which will reach southern Ontario first and claim the region?

At this point the storm will be a miss, like with the Colorado low. While the heaviest precipitation will remain south of the Great Lakes, it might bring a light shower to the northern shores of Lake Erie Thursday.

As well, temperatures will climb through the mid-week mark, but will then take another dive, however, on Friday, thanks to a brisk northeast wind. The official start of spring will feature abundant sunshine and pleasant temperatures on Saturday, though staying cooler near the shoreline of Lake Ontario.
