Dense fog this morning will create hazardous driving conditions due to low visibility, the National Weather Service said in a statement today.

A dense fog advisory is in effect until 10 a.m. Visibility is reduced to one-quarter mile or less.

Rain tomorrow will change to a wintry mix from northwest to southeast Friday afternoon, the National Weather Service said. There is the potential for several hours of freezing rain, sleet, and snow Friday afternoon. The freezing rain will lead to ice accretion on any untreated surfaces, making travel hazardous, potentially for tomorrow’s evening commute.

Additionally, any standing water from rainfall and melting snow will freeze, especially Friday night, the weather service said.
