High pressure dominates the country at the moment and with this pressure comes great examples of cloud inversions.
I took this shot on the way to work looking over Llanberis as the first sliver of sunlight beams down the Pass. Temperatures normally fall as you ascend, on average one degree per one hundred and fifty metres of ascent. On this morning the phenomenon was reversed and it was three degrees at Pen y Pass (350m) and minus one at Plas y Brenin (190m). The sun warms the upper slopes and the high pressure and lack of wind trap the cold air in the floor of the valley.
