I've had to get used to some new meteorological situations, since moving to the Coastal NE. It's a bit like being in Norfolk, because that county is nearly all North Sea coastal, but up here it's just a bit more so.
So the last five days have been this: Fog, cold (10c), damp, nasty. Suddenly today - it's crystal clear, warm, sunny.
You can bet that tomorrow will be one of: (a) Cold Fog, (b) Heatwave.
