Forecast Discussion: Valley residents are once again waking up to clear skies this morning, courtesy of a weak upper-level ridge over Arizona and high pressure spread out over the mountain west. Weather for this forecast period through Sunday will stay uneventful as surface winds remain primarily light and terrain-driven and skies remain mostly sunny-to-sunny, with a potential for the presence of high clouds over the weekend. A warming trend will also ensue, with high reaching the mid-60s Saturday and Sunday. Air quality, on the other hand, has a greater chance of being more newsworthy. By virtue that this is the weekend before Christmas, PM-2.5 concentrations may be augmented by extra festive fireplace activity as people get into the Christmas spirit. It is a weekend nevertheless. The aforementioned ridge will help promote stagnant conditions today through tomorrow afternoon as it creates a break in the stronger winds aloft. Winds strong enough to prevent stagnation will then return later Saturday and persist through Sunday. Inversions are also expected to develop each night. With minimal cloud cover, colder low temperatures can be realized, resulting in stronger inversions overnight. Overall, expect PM-2.5 concentrations to maintain Moderate AQI levels through Sunday, though ventilation during the daytime Saturday and Sunday will help keep them from running away. All other pollutants are expected to stay in the Good AQI category. Check back on Sunday for a look ahead at next week's weather and air quality. Until then, have a great weekend! -M.Graves
