It's possible the srfc temps could be tainted at times with erly flow, especially at the coast. But weaken the erly gradient enough and with 18-20C 850 temps....you'll have one of those 85F ESE seabreezes on runway 090 at Logan while West Roxbury is 96.
It does seem like we may try to trough more towards the 4th. At least on the EPS.
