Some places in the north of Scotland were more than 8°C colder than at same time just 24 hours earlier. Loch Glascarnoch at 12 UTC yesterday for instance was 12.3°C but only 3.7°C today. Not quite the 26°C difference we’ve just seen in New South Wales but 8.6° is still quite a drop. Interestingly many stations in and around the southeast of England were slightly warmer today than yesterday, despite the fact that two cold fronts and an occlusion had all cleared through this morning. It’s good to see that the Met Office have at last simplified their latest analysis in this regard.
