Visitors:
One visitor asked what we were looking at and thanked to me when I told him.
Weather:
Haze around Denver with a brown layer above the horizon representing a subsidence inversion (with PM 10 at a high level) which gradually cleared. Starting cloud cover cirrocumulus 35% which dissipated, with 20% at the end all cumulus far to the West. Cool all day especially out of the sun.
Raptor Observations:
The first migrant was an NH at 9:54 a.m. MDT. A group of 6 TV migrating together had to flap a lot while they were circling in a thermal. The high pressure zone over Denver created the subsidence inversion layer, which in turn kept thermals low until the layer dissipated, keeping the hawks at the level that we could find them, though the Soaring Forecast was for excellent lift at 15 ft per second with the height of thermals to 10,546 ft. AGL by 12:45 p.m. MDT. Non-migrant raptors: GE adult was dived on by a CORA, RT 6 one of which was carrying a stick in the Kestrel Channel followed by another adult RT perhaps reinforcing pair bonds, TV 1.
Non-raptor Observations:
https://ebird.org/checklist/S400164169 2 paraglider at 11:00 a.m. had no lift whatsoever staying low above the Coors Brewery, 1 at noon had moderate lift. A single hang glider had more than moderate lift.
Predictions:
Sunny, with a high near 83. West wind 5 to 7 mph becoming east in the afternoon. The winds I left are predicted to start in the West, change to the SE then East.
