see GFS 12Z DT for Tuesday has 850hPa temperatures 15 degC for SE
parts, start of summer ?

ATB, Joe
The current London ENS seems to favour a breakdown by Tuesday (not wishing to preempt Martin).It
looks like a thundery breakdown is possible Sunday evening as high theta w air is advected out of
Spain with cyclonic development.Development of MCS s ,homegrown or out of France seems possible,even
allowing for the GFS overdoing the CAPE,
