More precipitation could be coming for southwestern Saskatchewan over the next four nights.

Environment and Climate Change Canada is projecting Swift Current and the area will experience thunderstorms tonight and showers the following three nights.

Stephen Berg, a meteorologist with Environment and Climate Change Canada, said the sporadic rainfall is due to an elongated trough spanning from the Northwest Territories to Manitoba.

"Given the unsettled nature of the overall flow these little ripples in the Jet Stream... it happens every 15 or 24 hours," he said is the reason behind the nighttime rain.

The weather pattern will create a "poppy-type situation" according to Berg in terms of rain each of the next four nights. Amounts could range from a trace to upwards of 10 millimetres.

"Some areas might get some locally heavier showers and thunderstorms but in terms of amounts, it's very difficult to say," he said. 

Last night's system produced 5.3 millimetres in Lucky Lake; nothing was recorded in Shaunavon.
