Weather on route out 1/10 to 4/10 low clouds to northern Yugoslavia where low clouds increased rapidly with 2/10 middle and 5/10 high level clouds. Over Alps to target there were 10/10 low clouds with tops at 10,000 feet, 2/10 middle clouds to 18,000 feet and 5/10 high clouds above 25,000 feet. Overcast low clouds broke rapidly between the I.P. and target becoming 3/10 over the target with visibility over 20 miles although there was a very heavy haze below bombing altitude. On the return there was a general decrease in all clouds, 7/10 low cumulus with ceilings of 5,000 feet over the southwestern Adriatic and southern Italy decreasing to 3/10 over inland areas and base.
