High 51F. Winds SE at 20-30mph. Good wind direction but rain may prevent a raptor flight. Perhaps some movement in the afternoon if there are periods without rain, but the current forecast is not looking good for raptors. Could be an interesting day for non-raptors with favorable overnight migration conditions and favorable winds the whole day. SUNDAY: Cloudy. High around 40F. Winds W at 10-20mph. Expect light to moderate migration. Probably South Lookout. MONDAY: Partly cloudy. high 47F. Winds NW at 5-10mph. South lookout. Expect light to moderate migration. ======================================================================== Report submitted by David Brown ([email protected] ) Derby Hill Bird Observatory information may be found at: http://onondagaaudubon.com/derby-hill-bird-observatory/ More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=358 -- New postings to the entire list: [email protected] Subscription configuration instructions: https://it.cornell.edu/lyris/basic-e-list-member-tasks Listowner contact: [email protected] Archives: https://www.mail-archive.com/[email protected]/maillist.html
