This tranquil interlude proves short-lived as a system currently over the Canadian Rockies prepares to bring a cold front through the region partway through this weekend
After enduring a remarkably cool and snowy first half of November, the Sault area now enjoys a brief but welcome respite as high pressure over central North America establishes tranquil conditions for the end of the work week. However, this tranquil interlude proves short-lived as a system currently over the Canadian Rockies prepares to bring a cold front through the region partway through this weekend. Behind this front, we set the stage for renewed lake-effect snow and gusty winds before the weekend ends.
Friday will be partly cloudy, with temperatures reaching 7°C, as high pressure over the Ohio Valley maintains dry, warm conditions for mid-November. The high pressure leads to weak winds, partly to mostly sunny skies, and a mild night across the region, with overnight lows near 3°C.
Saturday brings mostly cloudy skies with rain developing in the afternoon as temperatures reach 9°C. A cold front moves through the region later in the day, bringing little rain but cranking up the winds and eventually returning a much more seasonable airmass. Rainfall amounts of 2 to 5 mm are likely.
Sunday brings mostly cloudy skies, with lake-effect snow showers developing, and temperatures reaching only 2°C. In the wake of this system, sharply cooler northwest flow builds into the region for Sunday and Monday. 5 to 10 cm of snow is possible in any dominant banding Sunday into Monday. In addition to lake-effect potential, it will be quite breezy Sunday, with frequent gusts of 50 km/h possible, particularly near the lakeshores.
