Forecast Discussion: ***Ozone Health Watch in effect for Tuesday, June 30th, 2015*** Wow. We have a lot to talk about. The first significant thunderstorms of the season to move through the Valley occurred late Monday night. Between 10 and 11 pm, strong storms with frequent cloud to ground lighting barreled through the metro area. Rain was brief but heavy in spots. Totals were generally around 0.04 inches, so most of the streets were already dry by morning. One spot, near 25th Avenue and Cactus Road recorded over a half an inch. Much more rain is needed across the deserts to shut down the dust storm threat. With that said, Buckeye had the highest levels of PM-10 on Monday, and much of that appears to have been from local activity. Looking ahead, Tuesday is shaping up to be rather similar to Monday. Forecast models are suggesting storms could develop late once again in the Valley. One forecast model actually has storm rolling through the Valley by 2-3 pm. However, neither model is picking up on current activity around the state Tuesday morning, so it's tough to know if we can rely on the afternoon/evening solutions. Ozone levels soared above the standard at four east-southeast area monitors on Monday. The with a similar flow Tuesday, expect elevated concentrations once again in these areas. An Ozone Health Watch is already in effect. Levels should improve Wednesday. It appears that after Tuesday, we will have a break in storm activity. Wednesday through Friday may be down days. This should give us a chance to clean up any windblown debris before the pattern gets active again next week. Check back tomorrow for more. Until then, have a good day! -J.Paul
