Jokingly referred to as Glamorgan's 12th man, the Cardiff weather was no cause for amusement in the Gloucestershire dressing room on an infuriating final day that ended in a draw.
Only 30 overs were bowled, during which the magnificent Will Gidman bagged five of six wickets to fall and the hosts were reduced to 146 for nine in their second innings – a lead of just 59.
The almost superhuman Gidman finished with six for 50 from 25 overs, only for the elements to conspire horribly against him and his side's hopes of a first LV= County Championship win of 2014.
Heavy overnight rain had initially resulted in a wet outfield and an hour's delay to the scheduled start, Glamorgan eventually resuming on 80 for three and still trailing Gloucestershire by six runs.
The hosts would have banked on the vastly experienced Murray Goodwin to settle any lingering nerves, but he was gone for 32 in the fifth over of the day when he chopped Gidman onto his stumps.
Jim Allenby survived a vehement appeal for leg before three balls later, with height the only logical explanation as Gloucestershire's go-to seamer bent his back from the Cathedral Road end.
The batsman was not to be spared for long, departing for a duck in Gidman's next over when a loose waft was punished by Alex Gidman's diving catch at first slip.
Effectively four for five, Glamorgan were pinning their hopes on steadfast opener Will Bragg and a lower order that spared them from complete obliteration in their first innings.
Bragg (43) had showed admirable shot selection, only to succumb to a leg-side strangle off Tom Smith as he was caught behind by Cameron Herring to give the spinner his first wicket of the season.
The Welshmen were now in serious peril at 106 for six, but Mark Wallace (10*) and Graham Wagg (1*) steered them though to lunch amid gathering gloom.
Sadly for the County the interval brought more drizzle – light enough to maintain hopes of more play but maddeningly persistent – and the action did not resume until 4.45pm.
Back came a fired-up Will Gidman, who had Wagg (1) fending at one to succumb to Michael Klinger's gully catch and was on a hat-trick when Ruaidhri Smith gloved behind to Herring.
Four overs later the all-rounder slanted one across home captain Wallace (15) and wicketkeeper Herring took his fifth catch of the innings.
A thrilling finale was on the cards, but an unbroken 10th wicket stand in 8.5 overs between Dean Cosker and Michael Hogan ensured Glamorgan had banked enough runs and time to save their skins.
