Temperature Range

My car registered 3C ....with the amber warning sign for possible ice....as I went for my walk this morning.....
In the middle of the day, the car’s dashboard registered 19C ....
( although I only captured 17C)!
This shows that 16C is the diurnal temperature range in Albir today.....
Clear blue skies, bright sunshine and no cloud cover......explains this big temperature range.....
