Forecast Discussion: Temperatures will be about 15 degrees above normal this weekend under sunny skies and relatively light winds. The is no real rain threat in sight for at least the next couple of weeks. In fact, we are entering Arizona's three driest months on average (April, May, June). There may be a slight "cool down" to start the week, but we're talking 93°F vs. 95°F. Air quality levels were in the Good range on Thursday. With high pressure peaking over the region this weekend, it's highly possible that we will see lower Moderate ozone across parts of the Valley. The typical drift during the day is west-to-east, so expect highest levels in the northeast and east part of the forecast area. Another sign that we are quickly drying out is the elevated morning PM10 concentrations in south-central Phoenix. The heating of the day will provide enough lift for surface concentrations to improve each afternoon. Check back on Sunday for a look ahead at next week's weather and air quality. Until then, have a great weekend! -J.Paul
