Forecast Discussion: You can feel the moisture out there this morning! Temperatures are in the upper 80s at 9 AM and dewpoints are ranging in the upper 60s to low 70s. We're heading for a warm and muggy day. The 5 AM weather balloon launch from Phoenix is showing a decent amount of energy for thunderstorms along with some upper-level dynamics, however, there are a few factors noted that would not be favorable for storms. First, much drier air is shown above 15,000 feet. Second, an inversion (or a "cap") is also found around 15,000 feet. Finally, steering flow is very light making it difficult for storms to get organized. This type of environment is expected through the weekend. Bottom line: only isolated thunderstorms capable of producing brief heavy rain are expected. These storms would mainly occur over the higher terrain and during the afternoon hours. With mostly sunny skies, lighter near surface winds, and lack of widespread rainfall, ozone and PM levels are beginning a gradual rise. Ozone concentrations in the Moderate range are anticipated by tomorrow, especially for the eastern half of the Valley. For those planning outdoor activities, high temperatures should top out near 100°F through Sunday. Check back on Sunday for a look ahead at next week's weather and air quality. Until then, have a great weekend! -J.Malloy
