OTTAWA -- Rain is on the way for the capital region.

In a special weather statement, Environment Canada is calling for 'significant rain' starting Thursday night into Friday.

The weather agency says many areas may receive total rainfall amounts of 15 to 25 millimetres.

In addition, there could be some freezing drizzle overnight Thursday night in the capital region and east along the Ottawa River Valley. That could make surfaces slippery, Environment Canada says.

The freezing rain will change to rain early Friday morning once temperatures warm up.

The special weather statement covers Gatineau, Ottawa and much of the area south and west of the city.

The rain is expected to end Friday morning in the Kingston area and early Friday afternoon in Ottawa.

Friday's high is expected to be 9 C, with a mainly cloudy day after the rain ends.

Things will cool down on Saturday, with a high of 4 C and a mix of sun and cloud.
