We still have an upper level low over central Washington that will drift southward into central Oregon today bringing a chance of showers to the Cascades.  There is also a weak trough off the coast moving eastward that is enhancing the marine layer which is bringing us thicker clouds and drizzle this morning.  We likely stay cloudy all day.

The trough of low pressure will split tomorrow as it nears the coast with most of the energy going north and south of the area, leaving us with only a slight chance of showers tomorrow night as it moves across.

The complex pattern expected for next week remains difficult to forecast as the models are also confused, showing several different scenarios.  We get to choose from high pressure over the area, a low pressure area just to the south, or a trough or low pressure area to the north.  For now, we go with partly to mostly sunny dry days Monday and Tuesday then partly sunny days Wednesday and Thursday with a slight chance of showers.  Highs next week could climb into the mid to upper 60s around the Tuesday-Wednesday time frame.
