Current UKMO run has a triple point on the front over SE England at 0Z
Tues.GFS/NMM has a weak area of CAPE over cent/southern England,warm
advection ahead of the front, a 100kt jet nosing south aloft and rain
turning to snow on a convective band.
Might be interesting as similar features have produced squalls,thunder snow
and weak tornadoes in recent years,
