Hot and clear. :-)
Saw two clouds in the 11 days we were in Turkey, but
with temperatures in the high 30's most of the time.  The
40-degree days occurred before we arrived.

Weather services provide 30-year means of temperature and
precipitation for any given day.  However, "normal" in my
experience rarely occurs - the mean is the average of extremes.
It would be interesting to see the standard deviation on
the climate numbers.
