Yesterday 1700, south east, was +18C on the ground and +19C at 4000ft
So, we have a strong inversion.
I was going to Tempelhof tomorrow, intending to do a short movie of the arrival, but the long TAFs indicate more of the same for EDDI too, which I simply do not believe as the MSLP chart shows an airflow over there from the warm and dry bits of Europe.
But this is just stratus cloud, about 1500ft thick, no haze to speak of really. Above is CAVOK, 50nm+ vis.
