16 Lessons Learned  Erie is a breezy place…it is easy for the wind to gust >20kts – exposure is good  A steady, persistent wind from the south at night, when the PBL decouples, will lead to divergence along the south shoreline and dissipation of echoes as they approach.  A due south wind has a marginal amount of a downslope component and can impede dewpoint rises!
