A week ago we had a run of days in which the temperature stayed between 10C and 12C both day and night. Now we have just had three days when it has been between -1C and +2C. With very little wind, it has been foggy and the trees have been covered with a sort of icy dew which continually drips from them. Some of the drops splash when they hit the ground, others bounce and roll around, like hailstones. Spiders webs are covered in ice and water droplets.
