#2682 "Morning Anvils and Congestus"

#2682 "Morning Anvils and Congestus"
8x10 inches oil

The morning sky was very convective. This is the third in the sunrise series for Thursday June 16th, 2022 that include #2680 "Singleton Morning Cumulonimbus", #2681 "Castellanus in the Wake of the CB" and #2682 "Morning Anvils and Congestus". 

Water Vapour Imagery at the time of the painting 

Water vapour imagery revealed that four or perhaps five lines of concentrated instability were spaced between the leading edge which had just passed Singleton and the cold front which would arrive later in the afternoon. The structure of those convective bands remain to be fully understood. Nocturnal low level jets figure prominently along with Langmuir streaks in helping to explain these bands. I used these tools in a forecast sense but lacked the observational data that would decisively determine the science behind these structures. 

Synoptic Situation Weather Map 

This view was directed toward the northern portion of the second line as it crossed the Singleton forest. The underside of an anvil from a thunderstorm along that line filled the sky. Secondary towers were developing from whatever surface convergence boundaries were created by the first thunderstorm. The air mass was very unstable with lots of convective energy. Shreds of SCUD (Scattered Cumulus Under Deck) cloud were racing around in the low levels on the atmosphere. These pieces over the Singleton forest were headed northward. Some trees within that forest would be knocked down later in the day. It is a small canvas but it contains a lot of meteorology to be discovered. 

The damage June 16th, 2022 was not as severe as the derecho of May 21, 2022 but still extensive. Both affected the Quebec City-Windsor Corridor, Canada's most densely populated region.
