Expect little change in our weather today right through Friday with a blocking pattern over the western states. Northcentral Washington can expect possible fog in the morning with mostly sunny skies by afternoon with highs today in the mid 30’s cooling to the low 30’s by Friday. Overnight low temperatures through the rest of the week will drop down into the mid to upper teens.

By Saturday, the upper level ridge axis that has been along the coast will move east allowing a weak wave to move across the region late Saturday. The best chance of snow Saturday will be along the Cascade crest where travel over area passes could be tricky late Saturday night. Highs to kick off our weekend will still be cold with highs around the freezing mark.

The weather pattern looks to transition to a more active pattern on Sunday with a series of systems moving into the Pacific Northwest. The first trough will move into the region Sunday bringing with it a 50% chance of snow both during the day and on Sunday night.

A warm front will slide in Monday changing our precipitation to a rain/snow mix with a 30% chance of precipitation, high on Monday in the upper 30’s. A weaker system will move through on Tuesday with a 20% chance of rain or snow.
