This was a common expression during my working life but thankfully nowadays when this term comes to mind this is what a get. Clear skies virtually all day. While the official temperature has still not reached double figures this year the car did show a temperature of 11 degrees at lunchtime today.
wow, Heatwave! Lovely blue sky. We had 10 degrees today, was a bit chilly but the sun was shining and it felt good to be outside. Meant to be about 17 degrees at 5pm tomorrow!
