KOIN Clark County forecast, July 5

The cool-down has begun for the Pacific Northwest — though you might not really notice it yet. The ridge of high pressure still maintains its presence over Southwest Washington, and our temps today will still be well above normal for this time of year — in the upper 80s. The bigger, more noticeable marine push comes tonight, with afternoon highs about 15 degrees lower Monday and a slight chance of showers on Tuesday.
