>Is very similar to 25A, looks like it was taken shortly before.
Looks like a good assessment. Anon is saying the black wispy remnants of the same rain cloud in 25D is traveling in a sequence, from the viewer's left front toward the viewer's right rear as seen in 25A Regardless of which was first or last, one can see it is same cloud traveling from winds out of the SOUTHEAST (to the left). Sunset is at the right, to the WSW at 241degrees. Wanna know something really cool? I checked the wind direction for 25DEC2013.
The wind direction changed at 1:50pm from out of the SOUTHWEST to being out of the SOUTH and remained out the SOUTH,,until 4:50pm when the weather station reported another change to being out of the SOUTHEAST.
That's a weather match for wind direction. Thanks again for posting 25D, Anon.
See caps re 25DEC2013 Wind direction and sky at sunset at 3:55pm. A short look st the weather site and it seems they do a reporting at 10 minutes before the hour, each hour. It could be the wind had changed before but said change being only reported at the next reporting. Seems a fair match, given that the weather station is to the West and might have recorded the wind change after London experienced it from the SOUTHEAST.
