If you’ve had enough of the heat, you might be glad to hear that the weather is finally breaking.

But you'll need to be on the alert, as a yellow weather warning for thunderstorms has been issued which is set to impact Wiltshire today (August 16) and tomorrow (August 17).

The Met Office has said to expect flooding, with fast flowing or deep floodwater to be possible, as well as disruption to train and bus services if lightning strikes as well as possible power cuts.

Here are the exact times we can expect thunder in all our Wiltshire towns according to the weather forecaster:

  • Westbury: 4pm today and 11am- 12pm tomorrow
  • Trowbridge: 4pm-5pm today and 11am- 12pm tomorrow
  • Chippenham: 1pm and 7pm today and 10am tomorrow
  • Melksham: 1pm and 6pm today and 11am tomorrow
  • Devizes: 1pm-2pm today and 11am tomorrow
  • Marlborough: 10am- 11am tomorrow
  • Warminster: 5pm today and 10am-12pm tomorrow
  • Bradford-on-Avon: 1pm and 5pm today and 11am tomorrow
  • Pewsey: 4pm today and 10am tomorrow
  • Calne: 4pm today and 11am tomorrow

The towns which are not due any thunder according to the hour-by-hour forecast on the Met Office are Swindon, Corsham and Malmesbury.

Dan Suri, who is the Met Office’s chief forecaster for today said: “The change in weather regime will see the heat of the last few days slip away from the south and east, this will be increasingly replaced with more unsettled conditions with heavy showers, thunderstorms and torrential downpours being key hazards over the UK until Wednesday.

“Although not all places will be affected, where thunderstorms occur there is the potential to for very large rainfall totals, but when that heavy rain is falling on extremely dry ground, the risk of flash flooding is much more pronounced.

"With no meaningful rainfall in some southern locations since June, soils in these areas have become baked by the sun turning them into hard almost impenetrable surfaces.

“Any rainfall in these areas won’t be able to soak away and instead it will wash off soils and other hard surfaces, creating flash flooding in some areas.

“This excess water can rapidly inundate some flood-prone areas.

“Particular areas of cautions are low-lying stretches of road and those areas adjoining sloping fields where water can quickly run off, creating fast-emerging hazards.”
