Synopsis and Discussion
   A weak are of low pressure remains overhead but will continue to weaken while moving east throughout the day.  High pressure will return through much of next week leading to a warming trend.  Weekend desert temperatures will climb from near 80°F in Saturday and Sunday to almost 90°F in some spots by next Thursday and Friday.  Conditions will be good for local ozone generation this weekend, with additional precursors drifting towards the forecast area from the deserts of western Arizona and southern California.  It's likely that concentrations will be in the "Moderate" range on Saturday and Sunday, possibly holding there through much of next week (for more information on Ozone and how it may affect your health, visit AirNow.gov).  Particulates will likely continue to slip further into the "Good" range as long as winds remain fairly light and mixing heights keep increasing.  Overall, it will be a great weekend for outdoor activities weather-wise.  Those who may be sensitive to Ozone may want to slightly limit outdoor activity over the next week or so.     -J.Paul
