rain

The heavy rain we saw earlier this week was part of an "atmospheric river" carrying moisture across the Pacific, but it's gone now, and off-and-on showers will be the norm for the next few days, says Cliff Mass, KPLU's weather expert and a professor of Atmospheric Sciences at the University of Washington.

Northwest dampness comes as the rest of the country is drying out, and Mass says that's good news for President Obama. He cites research that shows Republicans do better when it's rainy on Election Day, and Democrats do better when it's dry.
