Some mid to high clouds have been streaming in overhead with a mix of sun. Progressing into Sunday, generally the same set up with temperatures a touch warmer across much of the area with likely the warmest temperatures we've seen this year thus far with temps in the mid 70s, even upper 70s for locations in the Cascade foothills. The same weather trend will continue into Monday, with more places seeing low to mid 70s - with areas along the water seeing more upper 60s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
An upper level low will move inland near Oregon which could allow wrap around moisture through Washington. Precipitation chances start to increase more so Tuesday into Wednesday as the low moves further inland. Temperatures look to return to normal during this time, in the upper 50s to lower 60s. Some ensembles are starting to key into warmer and drier conditions returning near the end of the week and into the weekend, potentially back in the upper 60s to lower 70s.
