WALLA WALLA -- The run-up to Thanksgiving could get a bit slippery over the next few days.
Rain is in the forecast tonight, followed by a cold front that could bring snow levels down to lower elevations by Friday.
According to the National Weather Service, the cold front is expected to cross east of the Cascades on Thursday, bringing rain to the lower elevations and snow showers to the mountains. High temperatures are forecast to drop into the low 40s by Friday and into the mid-30s by Saturday. Nighttime temperatures will drop below freezing with a low of about 25 degrees forecast for Saturday night.
The main low pressure system will invade Washington and Oregon on Friday, lowering snow levels down to the lowest elevations. Several inches of snow are possible over the mountains with light accumulations elsewhere.
There will be a brief break in weather systems on Saturday and Sunday but the next system will return early next week for more snow over the mountains and valleys and a mix of rain and snow at the lowest elevations.
