#2640 "Singleton Warm Frontal Altocumulus Overcast"

This was a classic warm frontal surface as viewed at 7 pm on Wednesday March 30th, 2022. 

The easterly cold conveyor belt was brisk setting up the conditions for a bout of freezing rain. The eastern basin of Singleton Lake was fairly calm being protected from the easterlies by the forest. Algonquin would experience a significant amount of icing with this event whereas the duration of the freezing rain at Singleton was overnight and fairly brief. There were no real impacts. 

The lake ice was still hanging on over the western basin of Singleton. Every now an again a chunk of ice would break free to be carried by the current of the spring flood. Big chunks of ice would be driven onshore in the entrance to Jim Day Rapids. Water would drain from these landed pieces of ice and they would become bright white in dramatic contrast to their darker blue colours when they were floating. The chunks of bright white colour always caught our attention as we thought briefly that the swans had returned to feed. 

Southwesterly Langmuir streaks were imbedded within the overcast. Some gravity wave appendages were attached to these streaks and those waves were perpendicular to the winds riding up over the wedge of cold air at the surface. 

The warm sector arrived Thursday afternoon and the temperatures soared to plus 16 Celsius for a brief before before the cold front arrived. The weather is always interesting and we just need to take the time to appreciate what the clouds have to say.
