Scotland warned of thunderstorms and rain over the next four days following weeks of hot weather.
The Met Office said a yellow thunderstorm warning is in place for most of the country for 12 hours from noon on Tuesday
Yellow rain warnings also follow for all of Wednesday and the early hours of Thursday morning.
Experts have warned of potential damage to buildings as a result of floodwater, lightning strikes, hail and strong winds.
The Met Office also warned of delays and cancellations to public transport as well as potential disruption on roads.
It comes after areas across the central belt were hit with close to 30C heat last week.
STV Weather reporter Philip Petrie said: “Unfortunately the fine dry and sunny conditions many of us experienced last week and over the weekend are taking a bit of a turn this week as low pressure takes control of the weather. This will keep things feeling changeable and unsettled for the rest of the week.
“Already today the Met Office have issued a couple of weather warnings to start the new week. Tomorrow we have a warning for Thunderstorms – this is due to the fact we are retaining the warm conditions from last week but adding the effects of low pressure, so we are likely to see some heavy, persistent and thundery downpours.
“The warning area covers a large part of the country, stretching down from the Highlands to Dumfries and Galloway and parts of the Borders. We could see some local transport disruption and flooding.
“Come Wednesday a rain warning comes into effect as the rainfall totals begin to top up – again we could see some localised flooding and travel disruption but the warning area covers a smaller part of the country.
“Of course the rain may be welcome by some, after all the dry and humid conditions lately it may be some relief for farmers and those who struggle in the heat.
“The unsettled conditions look set to continue for the rest of the week, and it is likely the Met Office will issue further warnings, so we will be keeping an eye out.”
