The good folk down in the Met Office in Exeter were promising plagues of frogs, boils, locusts and worse for today, but it looked fine so we went for a sort of local walk anyway. As we went round, we could see the clouds starting to develop, with nice threatening black bits, then shutting themselves down as their shadows turned off the heat source. I reckoned it would be fine but Mrs N, who does not "do" sauntering, settled for a near 4mph pace to get round quickly, which did not go down well with me in the prevailing humidity. Perhaps my peripatetic dissertation on cloud formation, vortex stability, adiabatic lapse rates and the effects of latent heat of evaporation spurred her on. Either that or she hates me!
Turned out the Met Office was right though. An hour after we got back it honked down so hard the road outside the house flooded.
