I am pretty sure you can see it already. In the german Meteoros Forum (http://www.meteoros.de/php/viewtopic.php?t=6329&highlight=) many people write about very unusual sunsets in Germany.
So keep an eye on the dusk!
I had a feeling this might be the case. I just need some clear skies! Last night was 'supposed' to be clear, and today is 'supposed' to be sunny and hot, but instead it is just grey and overcast - typical British Summer!
