Patchy fog that hovered over parts of Portland Saturday morning should lift by 11 a.m., the National Weather Service says.

Visibility in some areas - such as the Hillsboro Airport -- was a quarter mile or less, according to the weather service. Temperatures that were near freezing Saturday morning in a few areas could cause slippery roads.

And while rain is predicted from Sunday through Friday, not so on Saturday. After the fog completely lifts, it's expected to be partly sunny with a high near 47. Saturday night, there's a 10 percent chance of rain with a low around 39.

Sunday is expected to arrive with patchy fog with rain arriving after 5 p.m. The high will be near 48. Rain on Sunday night could be heavy at times with a low around 43.

Showers are expected Monday, mainly before 11 a.m., then a chance of rain after 5 p.m., with a high near 49.

At Mount Hood, partly sunny skies were expected on Saturday. Mount Hood Meadows is opening on Saturday and Sunday in anticipation of daily operations beginning Friday.

At Government Camp, which is at an elevation of 4,416 feet, the weather service predicts a high near 41 and partly sunny skies on Saturday. On Sunday at Government Camp, rain is expected after 4 p.m., with a high near 39.
