High pressure will continue to dominate the weather for the next week. Dry weather will prevail across the state through at least the middle of next week, at which point a slight chance of rain returns for western Washington, although continued mostly dry conditions are likely. Temperatures will be generally above average in the lowlands, and well above average in the high Cascades. Stable conditions and limited atmospheric mixing could be cause for possible air quality concerns, especially in typically stagnant valleys and parts of the basin in central Washington. Air pollution will be less of a concern in ventilated areas such as the Mt. Vernon areas and parts of the coast, which will periodically receive increased mixing from warm, easterly winds. Areas in western Washington that mix out will also be quite warm and fog free, with highs possibly reaching 60, while calm areas may remain in the upper 40s to low 50s. The east wind at the coast could subside by the middle of next week. Stagnant areas in central Washington and in the interior southwest will have a risk of night-time fog or freezing fog, although the strengthening February sun makes widespread day-time low clouds unlikely. Even areas with morning fog should be sunny by mid day.
