Hi HB,

In case you are interested.

Based on our leaf-out phenology model, temperatures to date this year, and the 10-day forecast as of 24 April 2019, our predictions for leafout on the Main bird plot:

Budburst = 11 May,

90% completion of leaf expansion = 24 May.

More details in pg 2 of enclosure.

 

If the budburst date is accurate, it will be about 3 days earlier than expected based on the 60-year trend (page 1 in enclosure).
