Under the Weather Part 1

The rain poured down onto Ankh-Morpork, flowing down the city's gutters into*1 the River Ankh. Blobs and blobs shattered onto the city streets, watched by a figure sheltered by a statue of Lord Salluci the Only Slightly Bonkers.

Theodd "Two Kippers" Lem, a Class III Mumbler, tried to light a smoke with a dampened match.
"Two bloody kippers? Bloody waste of time, I told 'em. Two shillings for an ex-soldier, sir?" he said to a scurrying figure with a broken umbrella.
"Bloody kippers. Who eats kippers for tea anyway? Waste of time, kippers. Now shrimps, there y' got something."
A flash of lightning seemed to shoot upwards from the Alchemist's Guild for the third time today, but Theodd paid little attention, still mumbling short tirades about kippers.

A short figure plunged into the pavement beside Theodd. This turn of events interrupted Theodd's angry rant against today's kippers, and he leant over the unlucky figure. Its eyes sprung open. A shiny pointed helmet seemed to have protected the man from the full impact of the fall. He struggled to his feet, and stared at Theodd for a second, before refocusing.
"Ah! Knew it! Low pressure system, definitely. The slowsilver*2 definitely changed. Coulda tole 'em that. Needs more octamarine, though. 's too weak. And perhap's not quite so much juice." spouted the man.
With that, he stumbled off towards the Alchemist's Guild. Theodd stared blankly for a few seconds, then stuck his cigarette in his mouth. The fact that it was the wrong end probably had something to do with him not noticing the sun coming out from the clouds.

*2-Like quicksilver, only slower
