Fig 3. Analyses from the eta model initialized at 0000 UTC 10 November, 1996 for  A). MSL pressure (contoured every 2mb), 1000-500mb thickness (contoured every 5dam) and winds greater than or equal to 25 kts.,  and B). 850mb heights (contoured every 30dam), and winds greater than 30 kts.   After a few days of poor flying conditions, the birds have somewhat more favorable winds and no rainfall, it's time to head south for the winter!
