29/13:59: Heavy Snow - London & South East England

FLASH Warning of Heavy Snow for London & South East England valid from
1600 Tue 29 Dec to 0300 Wed 30 Dec

Only for the usual suspects of Bucks and Oxon, though (which
meteorologically I think shouldn't really be included with the SE). And
on the station reports from 1700 (I think it was), I noticed that it was
indeed snowing in High Wycombe.

At a height of 190m I'm not surprised that it has turned to snow in
High Wycombe. Wasn't that where shoppers were stranded last Monday
night?
