18z sounding from Percy Warner. Our weather balloon project. Funded by you thru Patreon. Temps very cold at the surface, well above freezing from about 1,200 feet to 3,700 feet up, then back steadily colder and below freezing over 3,700 feet. This helps improve forecast quality. pic.twitter.com/KdmCIv4BBf
