        A good example of the CS sunshine recorder's greatest
        weakness ... burn spread.   The card has a continuous trace
        since 0530z,  whereas during the last couple of hours I doubt
        whether the sun has been shining much more than 50% of
        the time

Drove through the TS on my way from St. Albans to Bletchley - very heavy 
at times, but quite localised. In the heaviest bits I'd have estimated 
the rainfall rate at around 100mm/hour, there was significant flooding 
on some of the back roads round Potter's Crouch with one section of 
Appspond Lane under around 9" of water. Much less intense through Hemel 
Hempstead but then a HUGE downpour, with some significant hail (5mm 
hailstones for around 30 seconds at the start) around Horton. By the 
time I got to the Leighton Buzzard bypass it was dry with no sign of 
recent precipitation.
