Yesterday, there was a severe frost in St Ives, a dusting of snow in Godmanchester but proper snow in Huntingdon...or was there? The debate raged on until after the snow had melted: Had the district been snowed upon? The crunch under foot said yes, national weather forecasters said no, it was a frost. And this photograph taken in Godmanchester does not make it much clearer. In Huntingdon, car windscreens were also covered with 'snow' centimetres thick. In fact, snow is defined as a frozen precipitation in the form of white or translucent hexagonal ice crystals that fall in soft, white flakes. Temperatures are predicted to be back up to 12C by Saturday.
