High Pressure
17th December 2021
Temperature inversion conditions in the hills with a high pressure system providing cool overnights (frost to valley floors) followed by mild daytime temperatures on the tops and some hill fog; although for the most part it was bright overall, with the fog lifting in light winds, as the day progressed.
