[iapennell]

At home near Nenthead in the North Pennines, the temperature dropped to -8C a couple of hours ago, it has recovered slightly to -7C at present with a slight south-east breeze picking up. Lovely and clear outside, fantastic view of Orion and Taurus (with the Pleiades)  outside my bedroom window! 

Certainly the lowest temperature that I have recorded at my automatic weather station since March 2013!
