If you don't own an umbrella, now might be a good time to get one.

CBC's Leisha Grebinski spoke with weather specialist Wayne Miskolczi about what people can expect to see.

The heavy rainfall is due to a stationary low pressure system that is developing in central Saskatchewan. This system is expected to affect most of the province, but the heaviest rain will fall in the cities of Saskatoon and Prince Albert.

There are also rainfall warnings for areas around La Ronge, Île à la Crosse, Buffalo Narrows, Beauval, Martensville, Warman, Rosthern, Delisle, Wakaw, Shellbrook, Spiritwood, Duck Lake, Meadow Lake, Big River, Green Lake and Pierceland

Communities near the rainfall warning zone can expect to see up to 25 millimetres of rain on Friday, while those farther to the south and north are looking at between 10 and 20 millimetres. Environment Canada says there is also the possibility of thunderstorms in those areas and around Prince Albert.

Saskatchewan can also expect gusty winds from the west that will bring in cooler air. The rain is supposed to linger into Sunday before tapering off.
