More rain is on the horizon for Saskatchewan as a thunderstorm is expected to move across from Alberta tonight.

That might evoke bad memories for some communities that were pounded by protracted, heavy rains in the last week.

That includes the communities of Saskatoon and Weyburn, among others, which both saw flooded streets and possible water contamination.

The upcoming storm is luckily not going to have those same charateristics, as Environment Canada Meteorologist Terri Lang explains.

"That's probably not going to be the case. Certainly could see some brief, heavy downpours, the thundershowers moving through the southeast will have a pretty good pace to them, so moreso brief downpours and maybe some small hail, and of course always those gusty winds."

Some northern communties might feel a bit more rain, but lang says the southeast looks safer.

"The weather system is kind of getting itself wound up in Alberta, and it'll slowly cross into Saskatchewan over the next couple of days. Right now, the biggest threat of severe weather is more over the northern grain belt and towards the central regions of the province. There's likely to be some thundershower activity that kind of drifts over the southeast area in the overnight period, shouldn't be too severe there."

What will come with the system is much cooler temperatures.

From the low 30s today, the temperature is expected to almost halve by Saturday, thanks to shifting winds.

"What we will see is the wind shifting to the northwest by the end of the day, and that'll usher in some cooler air, certainly for Saturday. We'll see some gusty winds, probably some rain showers, and much cooler temperatures."

Past that, temperatures are expected to get closer to the seasonal average as the week of highs and lows draws to a close.
