A milder airmass will be moving in tonight as ridging builds into the region. At the same time, the surface gradient will increase, increasing the wind speeds across the area and allowing some of the shallower valleys and wind prone areas to mix and warm. However, the deeper valleys and basins will form sharp inversions overnight as skies remain partly cloudy to clear. Winds will likely skip right off of the top of the inversions leading to large changes in temperatures over a small area as well as decreasing air quality.
