The satellite picture shows an area of low pressure west of Astoria moving south along the Oregon coast. This cleared out the clouds overnight causing the temperatures to drop and for fog to form. Visibilities dropped down to under ¼ miles in some areas this morning and though the fog is burning quickly now, there is still areas with reduced visibility so drive safely. Once the fog burns off, around 10am, we should see mainly sunny conditions for most of the afternoon, with slightly warmer temperatures. There may be some showers develop inland today but they are not likely to make it across the coastal range. The low pressure area will continue to drift south today then turn eastward and move in over southern Oregon Saturday and off to the east by Sunday. This means we could see scattered showers all weekend, again, the question, would any of them make it across the hills? A weak ridge builds over the area Monday and Tuesday warming things up a bit, but with a strong onshore flow, not as warm as it could be, more like “normal”. Tuesday through Thursday, more unsettled weather is expected to return with periods of rain and rainshowers possible.
