Visitors:
A family were interested in what we were looking at. They said they hiked in Boulder earlier in the year, and one of the trails was closed because of raptors. I told them it was probably breeding PG, which are also supposed to breed on the Tiers of Zion along the NW face of Mount Zion.

Weather:
The prolonged and heavy rain yesterday had washed out most of the smoke from the air, though there was some smoke close to the ground making Denver hazy, though as the day wore on the haziness decreased to the point that I could even see Denver International Airport to the east at 39 km without optical aid. Cooler air but without the smoke the sun felt hotter on the skin. Lots of cloud cover mainly cirrocumulus to the east with some cumulus congestus developing later in the West, eventually becoming dark nimbostratus. At the beginning of the 12:00 hour DST there was distant and prolonged thunder, and my app showed it to be 7.6 miles away only - the danger of being hit is if it is closer than 10 miles - and then it began drizzling, so we left.

Raptor Observations:
The first migrant an RT was at 9:12 a.m. MST initially seen far to the east, lost lift, then flying low in the gap between Green Mountain and Lookout Mountain. All the migrants were very distant. Non-migrant raptor sightings: CH 1, RT 6, TV 2.

Non-raptor Observations:
Migrating Common Nighthawk 13, VGSW 2, WTSW 1, BTHU 1, SPTO 1, GTTO 1 juv, CORA 5, MODO 2. Three paragliders starting at 10:00 a.m. DST with excellent lift.

Predictions:
A 20 percent chance of showers and thunderstorms after noon. Mostly sunny, with a high near 82. Light and variable wind becoming east 5 to 7 mph in the morning. Earth.nullschool.net suggests winds aloft from the ESE.
