#2792 "Another Side to Queen Anne" 10x10 inches oils on canvas |
The air mass was also very unstable and conditions were conducive to tornadoes. Singleton was included in a tornado watch area although the strongest threat was to the north along the warm frontal surface stretching through Ottawa. The so-called triple point is the intersection of the warm front and another line of instability like a low-level jet or outflow boundary - typically ahead of the surface low... where there will be ample cyclonic wind shear. Sunshine in the warm sector provides heat. We had 5 mm of rain with the morning convection that provided additional moisture as a fuel. The dew points were a bit low in the warm sector which should be 20 Celsius or higher for really severe energy.

News reported that a tornado touched down in Barrhaven, near Ottawa and damaged 150 homes.
This was the third and final painting in the Queen Anne's Lace Trilogy: #2790 "July Queen Anne's Lace"; #2791 "Queen Anne's"; and #2792 "Another Side to Queen Anne".
