Dickensian Weather

...External heat and cold had little influence on Scrooge...

...No warmth could warm, no wintry weather chill him...

...No wind that blew was bitterer than he, no falling snow was more intent upon its purpose, no pelting rain less open to entreaty...

   Foul weather didn't know where to have him. 

The heaviest rain, and snow, and hail, and sleet, could boast of the advantage over him in only one respect.  They often "came down" handsomely, and Scrooge never did.

Once upon a time—of all the good days in the year, on Christmas Eve—old Scrooge sat busy in his counting-house.  It was cold, bleak, biting weather...

...foggy withal...

...and he could hear the people in the court outside go wheezing up and down, beating their hands upon their breasts, and stamping their feet upon the pavement stones to warm them...

...The city clocks had only just gone three, but it was quite dark already—it had not been light all day...

...and candles were flaring in the windows of the neighbouring offices, like ruddy smears upon the palpable brown air...

...The fog came pouring in at every chink and keyhole, and was so dense without, that although the court was of the narrowest, the houses opposite were mere phantoms...

...To see the dingy cloud come drooping down, obscuring everything, one might have thought that Nature lived hard by, and was brewing on a large scale.
