Yeah, there were some amazing clouds - huge cumulo-nimbus, white and dark grey, some of them had tattered, feathery edges and I think I saw some anvils amongst them, too.
BTW, I cam home shortly after this snow shower and the temp (according to the car, which seems pretty accurate) was 6.5 degrees! I guess that might have been the effect of the sun coming out after the big cloud had passed over. However I arrived back home in Southampton just after it had snowed here and the temp was 5.0.
Prob shouldn't have hoped it would settle, then!
