daytime 2:12 pm, large areas of clear blue sky with some clouds

2:12 pm , Thur. April 07,2022 . After periods of heavy showers the previous days the sky was very clear with large patches of blue sky with some broken clouds in between. In my open backyard I had been looking up at the sky for the usually common sight of incoming passenger planes approaching the Atlanta airport from a northerly direction starting their descent towards the west side of the airport. Surface winds from the west gusting 15-20 mph in my area and must have been strong enough for planes to use an eastern approach, so I didn't see or hear any passenger planes. While looking up straight over head I noticed at What I first perceived as a translucent balloon moving almost straight north. I then realized it was way above the clouds moving north fast enough that within 90 seconds it had moved halfway across the sky disappeared behind some clouds above. I still thought it could be a large almost clear weather balloon with a spherical shape. I went into my house around 2:25 pm and looked up the current jet stream maps for my part of west Georgia. Information from the current maps indicated the jet stream was moving in a northeasterly direction during or about 2:12 pm and at the approx. time of my sighting . Due to the fact it was definitely moving north instead of northeast , It seems unlikely to be a weather balloon caught in the jet stream. Possibility exist that it just a very high military plane of some uncommon design. So after nearly 75 years, was this my first ufo?
