Recent updates to forecast include increased rain amounts in some areas and heavy rain areas reaching farther north than originally expected.

From the NWS Medford:

An atmospheric river (AR) will take aim on the forecast area tonight through Monday. With a moisture source from the deep tropics, it will feature heavy rain, gusty winds at times and snow levels above 7000 feet. Snowmelt and increased runoff will result in significant rises to area rivers, streams, and creeks. Models have been consistent in showing the greatest potential for heavy rain in Curry/western Josephine Counties, but recent trends have shown more rainfall farther north.

So, have expanded the areal flood watches northward. Small stream and urban flooding is likely in those areas. Main stem river flooding is possible with some like the Coquille/lower Rogue/Umpqua/Sprague getting to action stage/bankfull, though no current main stem rivers are forecast to go above flood stage. This may change, so keep checking the forecasts. Forecast graphics below have been updated.
