Hello CJE and thanks for the comment!
When I gave the clear edge in intelligence to RAF one main reason was the weak strategic reconnaissance of LW but I had not thought the weather forecasts. Thanks for that insight! Germans flew numerous weather reconnaissance flights and had weather ships on northern waters, so they tried to solve that but could not overcome the British advantage in the geographical location. After all through their history British have had that advance which had made attack on them difficult and had helped them greatly for example during their wars against Dutch in 17th century.
Yes, English weather is full of surprises. On the Germans' difficulties to assess the damage they had done, it was partly because almost everyone, also British, had greatly overestimated the effects of bombing before the war. British learned much by studying the effects of LW's bombing in GB and used this info in their efforts to increase the effects of BC's attacks.
