#2339 "Sunset Before the Rain"

I always try to enjoy the sunset. It is a quiet time of the day to reflect back on the events and activities of the previous twelve hours.

There were seven jets and as many contrails in this Singleton sunset sky. The high level deformation zone had already passed well to the east of Singleton Lake. The upper levels of the atmosphere were moist and these contrails would hang around until well after dark. The gravity waves in the much lower deck of altocumulus revealed northwesterly, storm-relative winds.

I believe these clouds were supported by the paired cyclonic vorticity maximum across the deformation zone from the anticyclone of the warm conveyor belt. I had to ponder this for a while and use my right hand until the various pieces of the weather puzzle fit together best. It is OK to be unsure at times and await new confirming data.

It would seem that the jets were riding this tail wind to get to their destination as well. The contrails were still catching the last rays of the sun. The colours of the sunset horizon were very strong and exciting. Rain at times heavy was beyond the horizon.

I might have guessed but I did not know that the next day would dawn with a declaration of emergency for Ontario. Other provinces would follow. I was self-quarantine-ing anyway at Singleton Lake trying to avoid the COVID-19 pandemic. (Corona Virus Disease 2019) and quite enjoying the quiet opportunity to continue with my series of weather panels.
