Oh don't worry, they were all over it this morning in the AFD. "Light rain ahead of the front will reach the SW WA coast early this afternoon and slowly move SW across the forecast area, reaching the Portland metro area around 4PM, Salem around 8 PM, and Eugene around 10 pm. The 12z model soundings show an interesting temperature and moisture profile mainly to the north when the precipitation first arrives. The surface is forecasted to be above warming, but the layer just above the surface is projected to be below freezing. This suggests that some snow could be mixed in with the rain initially. The precipitation will be light during this time, and do not expect any accumulations, but have updated this evening`s forecast to have a few hours of a rain/snow mix for parts of the Willamette Valley, the Columbia River Gorge, and the lower Columbia River Valley."
