The National Weather Service is forecasting areas of freezing fog tonight through Thursday morning.
.SHORT TERM...Tonight through Wednesday...Weak disturbance along the Oregon coast will move slowly south and showers should diminish during the night. Lots of clouds remaining but expect cooler temperatures overnight will contribute to fog formation. Fog that does form over the interior valleys will likely be freezing fog, but road temperatures are probably still too warm in many urban areas for ice. However, on some of the outlying roads we could see ice developing even on road surfaces and bridges.
