A cold front will pass through Northcentral Washington today cooling off our temperatures down to the mid 70’s under mostly sunny skies. West winds will also kick up this afternoon 10-15 drops down from Canada and will allow for a better chance of light showers for Tuesday and Tuesday night. Highs tomorrow in the lower 70’s with a 20% chance of rain.

On Wednesday through Friday, an upper level trough will move into the region from the Pacific and slowly move through the state Thursday and Friday. Several weak disturbances will move through the trough and will keep conditions cool and breezy at times, with mainly mountain showers. There is a 30% chance of showers and maybe even a thunderstorm on Wednesday dropping to a 20% chance of rain Wednesday night.

We will stay cool but drier on Thursday and Friday with afternoon high temperatures still on the cool side mainly in the lower 70’s.

Saturday through Monday, it looks like a flatter westerly flow will be over the region. This will not be a totally dry pattern but the chance for afternoon showers will be much less. Temperatures will also have the potential to warm up into the mid to upper 70s, which is or maybe a little above normal for this this time of year.
