MOTORISTS were today being warned of rush-hour downpours as heavy rain and thunder was expected to sweep in.
Forecasters predict more than an inch of rain could fall in some parts of Glasgow this afternoon with a risk of localised flooding.
With days of soggy weather, it is expected that sodden ground won't be able to cope with more rain.
Around 8am today one lane was closed on A814 Clydeside Expressway eastbound in Glasgow between the Stobcross Road junction and Finnieston Street junction due to flooding.
Earlier this morning there were reports of flooding on the A77 in Girvan, South Ayrshire.
Chris Burton, a forecaster with the Meteogroup, said: "There is a high chance of thunder and heavy downpours coming in from the south this afternoon and they are likely to last through rush-hour.
"It will clear away in the early evening, but more will be on the way. There is a possibility of localised flooding and some areas could see more than an inch of rain fall. It will feel pretty humid today with temperatures still around 19 or 20C."
As schools broke up for the summer holidays, it looks like the first few days will bring a mixture of weather with an unsettled weekend.
Mr Burton added: "It looks like being a very unsettled few days.
"Tomorrow there is a risk of more heavy showers but over the weekend it might become fresher but still with a chance of showers.
"Temperatures will dip down to around 15C or 16C."
The unsettled weather comes just a week after the west was battered with wind and rain.
Last Friday residents near Airdrie had to be rescued by boat when a thunderstorm caused flash floods which deluged into a row of houses.
Hours of torrential rain on Friday afternoon saw The Crescent flooded out.
Firefighters from Cumbernauld, Kilsyth and Clydesmill in Cambuslang were called – and soon had to be joined by Strathclyde Fire and Rescue's specialist water rescue team.
