Crescent Moon January 14, 2016

The first invasion of the polar vortex of the season to Northeast was taking place earlier this week. The frigid air mass travels over the open water of the Great Lakes causing the formation of significant lake effect snow bands. If you are on the leeward of this air flow, you’d be getting feet of snow in no time.

Many of you ask us how often we get buried in the deep snow after seeing our proximity to Lake Ontario while visiting our Tasting Room. The answer is “not much”; at least not as often as you might expect.

The heavy snow fall occurs most often when the air travels the longest fetch of the Lakes: longer the path, more moisture supply for the snow bands from the Lakes. Thus typically the heaviest lake effect snow episodes occur with the westerly airflow to the east of the Lakes. So for us here the lake effect snow becomes an issue when the wind direction changes more toward northwest.

This Monday the weather pattern was a textbook case of the heavy lake effect snow to the east of the Lakes behind a strong arctic cold front. I saw the Lake Ontario band over the Lake a little offshore from us with lots of whitecaps surging toward the shoreline. I turned back to the vineyards and saw the Lake Erie band above the horizon. In between there was sunshine all day long with a few stray clouds every now and then though it was windy and pretty cold.

The sun was already behind the Drumlin and the western sky was bright in the evening glow from the horizon to the mid sky. The Moon appeared to have started to be laid back — when you see a crescent moon, it looks either standing up straight in fall or laid back in spring, or in the transition phases in between. In the piercing west winds in the middle of the lake effect snow bands I was confident to have found a sign of the coming spring.
