Two pressure systems are dominating the weather in southeast Saskatchewan this weekend. 

"What you're dealing with right now in southeast Saskatchewan," explains regional meteorologist, John Paul Cragg, "is the remnants of the low pressure system that passed across the province Wednesday and Thursday. It's sitting in Central Manitoba right now and it's moving very, very slowly eastward." 

"In behind this low pressure system, there's an area of high pressure that's going to be moving into the province and it won't be able to move east like it normally would because that low that is now in Manitoba, will be sitting in Northwestern Ontario over the weekend and most of next week. It will stop that high pressure system that's moving into Saskatchewan from leaving." 

"So we're looking at weather for as long as seven days potentially, dominated by that area of high pressure so there's some lingering showers today associated with that low. There's a chance of thunderstorms this afternoon and tomorrow afternoon, but we're only looking at a 30% chance of precipitation."

"There'll be isolated thunderstorms popping up here and there.If you're unlucky enough to be under one you'll get a lot of rain. Otherwise, it'll be a mix of sun and cloud and pretty dry throughout southeastern Saskatchewan today and tomorrow."

After that, the high pressure system will move in throughout the rest of the week clearing away the clouds.

"We'll see mostly sunny skies, without much of a chance of any rainfall and not much a chance at all of any significant rainfall until we get to the end of next week."

Daytime highs and lows will around average for the week. However, tonight will be below average. 

"We're forecasting an overnight low of three degrees, it could get close to the freezing mark in some areas, especially low-lying areas overnight tonight but winds will be strong enough that frost is just a small risk. I's not a widespread risk."

The average overnight low for this time is 7.1oC. The lowest temperate was -2.8oC in 1984.
