Visitors:
A couple asked whether I were bird watching. I explained. They said Oh cool.
Weather:
Denver was clear for a change. The strong South winds probably blew away the inversion layer.The first hour had light winds from the ESE which turned the next hour into progressively stronger winds from the WSW. I hung my backpack to weight my scope and when it turned to level 6 on the Beaufort scale I turned my backpack so that if my tripod fell, my backpack would take the brunt and leave my scope undamaged. A few minutes later there was a tremendous gust which not only knocked my scope over but it flew downwind 5 ft. My files and papers went flying high into the air, as did my phone and little weather station with the batteries scattered and the cover lost. I was able to find my file 30 ft away stuck in a bush. The winds were predicted to get even stronger, so I left. On the way down winds were likely level 7, I was unsteady walking down the steps. I am guessing that the strong WSW winds were the South Winds sweeping around Lookout Mountain altering its direction.
Raptor Observations:
Winds at 12 mph aloft from the south would not blow apart thermals but would heavily tilt, fracture and drift them to the north. I wondered whether hawks wood fly against such a strong headwind, but sit out migrating today. By 11:00 a.m. I could see small puffy cresentic thermal capping clouds to the SSW and SE. The Soaring Forecast of the NWS predicted lifted 7 ft/sec, thermal height of 7,589 ft above ground level by 12:30 p.m. MDT, which considering that the watch is at 1771 ft AGL would make it 5,800 ft above the watch - a mile higher. The first hawk seen was a local RT in the Kestrel Channel but just over the trees. As I was about to leave a CH went up Clear Creek Canyon a little below eye level, the only migrant.
Non-raptor Observations:
A moderate to strong cold front is going through Saturday morning which could make for a good migration on Sunday or Monday. CORA 2. No other passerines.
Predictions:
A 30 percent chance of showers after noon. Increasing clouds, with a high near 53. Calm wind becoming north northeast 5 to 8 mph in the morning. The winds aloft are expected to be about 12 mph from the NNE changing to NE, which should give migrating hawks a good tailwind to fly south by.
