Observation start time: 08:00:00
Observation end   time: 13:15:00
Total observation time: 5.25 hours

Official Counter:        Greg Cleary

Observers:        Zach Gayk

Visitors:
37


Weather:
Temp 62-71F, dropping after mid morning.  BP 29.88 inHg, holding but
beginning to gradually drop by late morning.  Light/Gentle W breezes,
veering NW then WNW by late morning; returning W as precipitation arrived.
Good overall visibility w/moderate to thick haze.  Initially partial cloud
cover w/a thin, light gray bank of clouds off to the W; encroaching
overhead, becoming totally overcast by late morning and darkening
considerably.  A light rain began shortly before midday, becoming a steady
downpour by ~12:30 w/a steady reduction in visibility.  Approaching bank of
heavy rain w/thunder made the decision to call the count early an easy one.

Raptor Observations:
A sparse, dispersed flight; suppressed (undoubtedly) by approaching storms.
 Broad-winged Hawk remained at very casual height, passing in several small
groups of 3 or 4.  No flight to speak of once the promised precipitation
finally arrived late morning.

Non-raptor Observations:
2 Cedar Waxwing, 1 Alder Flycatcher, 1 Yellow-bellied Flycatcher, 1 Scarlet
Tanager, 1 Northern Waterthrush, 1 Northern Parula, 1 Mourning Warbler, 1
Barred Owl.

Predictions:
Another NW wind "grab bag" expected after stormier weather passes early/mid
morning.  It might not be half bad!
