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,

David,

Steady on now, predicting MCSs at that lead time !? ;-) All the models do
look very plumey indeed, let's enjoy the hot, sunny weather it brings with
it first, if you like that sort of thing.
