Just watched that giggly woman on BBC news channel having showed the
radar picture for the UK which shows a large area of cloud covering much
of Eastern England followed by the usual warning to slap on high factor
sunscreen because of the strong sunshine
Having seen the heavy Cu build up to virtually 8/8 cover here in the
south-east since late morning ,what could possibly cause this overcast
to dissipate and therefore come into line with what is obviously an
incorrect forecast ?
