Environment and Climate Change Canada has issued a heat warning for all of southwestern Saskatchewan for the second consecutive week.

A ridge of high pressure has begun to move into the region today that's expected to infiltrate the southwest for the next week bringing scorching daytime highs in the mid-30s and overnight lows in the mid-teens.

Brian Proctor, meteorologist with Environment and Climate Change Canada, said the southwest and western portions of the United States have been blasted with toasty temperatures this summer and those conditions are moving north into western Canada.

"That ridge is just going to continue to build as we move through this work week and into the start of the next work week at this time," he said. "That's going to allow a lot of warmer and drier air to move into southern Canada."

There's a slim chance for thunderstorms locally this evening but the next week looks precipitation and cloud-free.

"As this upper ridge builds in it's going to stabilize the atmosphere and we're going to see less and less of any chance of any much more than a little bit of a debris cloud floating around," he said.

He added people working outside should make sure to stay well hydrated, and if able, adjust their hours to work earlier in the day and or later in the night. 

"It's also important our livestock and pets are well watered as well," he said.
