Weather:
Wildfire smoke extending from DIA to the N and S Table Mountains, cirrus clouds 15-35% over Lookout Mountain from the ENE to SSW where the migrants would fly. Unusually, very few cumulus clouds developed in the West, taking till 11:30 a.m. DST for the first ones to develop. Cool breeze. The air was quite grainy with blurry looking hawks through my scope.
Raptor Observations:
At the end of today we have counted 78 SW which is higher than any total spring count since 1990! On my way up the steps to the watch at 9:11 a.m. DST I could see 2 AK, then 2 RT over the watch which were the first migrants. An adult FH fortuitously showed up in my scope while I was looking at a distant migrating OS over Lookout Mountain. 2 adult SW today. Most of the migrants as usual flew over Lookout Mountain with a few going through the gap between it and Green Mountain. An issue I tried to figure out today was where are the migrants after 1:00 p.m. DST. For a change there was no risk of thunderstorms or rain, and fortuitously there were large cirrus clouds extending from the SW to the East as well as overhead, and from the North to the NE extending to the East which I could use in the last 2 hours to check for migrants. I scanned high especially. At 1:00 p.m. DST an. OS migrated 10� above Lookout Mountain between antenna # 2 and 3 (counting from the East). At 1:15 p.m. 2 local RT were 12� above Lookout Mountain. In the last 0.5 hours scanning high to the NE over North Lookout Mountain I was able to binocular find 2 CH and 2 AK. While I was watching 3 TV to the right/West of the Westernmost antenna on Lookout Mountain I saw an AK migrating through. Non-migrant raptors: RT 3, TV 6. While watching an AK twice going along the Kestrel Channel, dropping toward the lowest part of the North face of Lookout Mountain, where one was attacked by an RT when another AK I hadn't noticed before dove on the RT; and another instance where a different AK was joined by another AK which I hadn't seen before, suggesting to me that there may be hawks going into the Kestrel Channel had a distance from the watch, i.e. not naked eye. I'll have to keep observing if this is consistent.
Non-raptor Observations:
6 paragliders had excellent lift going high over the mountains to the north. The Soaring Forecast of the NWS predicted lift at 6 ft per second and thermal height only 5739 ft AGL, though the trigger temperature of 80.3� F / 26.8� C was to be predictably reached only by 3:45 p.m. DST. ROWR 1,WTSW 7, BBMA 1, RBNU 1, STJA 12, SPTO 1, CORA 16, VGSW 3.
Predictions:
Sunny, with a high near 83. Light and variable wind becoming east southeast 5 to 7 mph in the afternoon. The winds aloft at the level hawks would migrate are very light from the SSW>S>SE>E.
