As of May 13, 2018, predicted mean egg development was 68% (62% last week) and model output indicates that embryological development was 5% greater than long term average. Greatest development was predicted to be across southern Alberta with potential for hatch occurring near Medicine Hat and Bow Island (Fig. 6).
