We have had a series of frosts this week. Today was cold and rather miserable – a black frost (a frost with morning cloud cover) – I am not sure if the daytime temperature rose much above 8-9 degrees C today which is a rarity around here even during winter – we are usually slightly milder than this. A related observation, across the river, is made on Velofille‘s photostream. And Phil. There is a change coming though – as always.
