CENTRAL FLYWAY 
Winter Trend Data - Central Flyway 
Most of the CENTRAL FLYWAY. experienced a dry, late fall with 
little snow or rain and with moderate temperatures. Just prior to and 
during the surveys a series of cold fronts developed, which brought snow 
and low temperatures as far south as New Mexico, Oklahoma, and parts 
of northern Texas. Further south along the coastal areas of Texas and 
Mexico, fog and overcast early in the period gave way to mild, clear-to- 
partly -cloudy weather. Everything considered, the weather was such as 
to hamper the survey by delaying many flights, but not such as to 
materially influence the estimates which were finally made.
