As a cold surface high pressure system continued to build down from Norway and over top of a still healthy snowpack over Grampian Scotland, conditions have become more favourable for significantly cold late March nights. With snow covered ground, stopping any warmth from penetrating the ground by day and clear skies,, light winds along with a very cold, dry air mass in place, this set the stage last night for not only the temperature dipping below -10C for a third straight night in Braemar but it was the coldest of the three and so cold (-12.5C) that it become the UK’s coldest Easter Sunday low on record. This smashed the March 31st, 1986 record of -9.8C.

With conditions remaining excellent for maximum radiational cooling over the snowfields of the Highland and Grampian Glens, the opening nights of April may push yet more records with further sub -10C nights likely.

See my post from last night which looks further at these conditions and a threat to the UK April record.
