Yesterday's strange clouds were reported in Kelowna, BC as well, so who knows where else they were seen.
It happened again today! Before I went indoors, the sky was clear blue at 3 pm. However, I did notice linear aerosol-like patterns in the southern sky. I came out 1.5 hours later (4.30), and these strange whisky looking "clouds" were everywhere!
We will be investigating this soon and speak with our local SkyWatch team to see if we can come up with answers. This is the second day in a row this strange cloud anomaly has occurred. I did notice NEXRAD ripples in these clouds, so that may help explain possible EM waves being used.
