Forecast Discussion: The ridge that lingered for quite some time has finally moved on and the jet stream has taken its place. Along with an increase in upper-level winds, surface winds are also showing signs of a slight bump. Unfortunately, the direction of these winds will be a slight concern. Typically in Yuma, west/northwest winds are a good indicator of dust activity because of the sand dunes located northwest of the region. And that's exactly what we expect by Thursday. Winds will likely be out of the northwest around 10-15 mph and can result in pockets of dust in certain areas around Yuma. If the winds hold and persist in the teens, then brief periods of blowing dust are possible. Moving on, ozone looks to be in a similar situation. Westerly winds are highly favorable for ozone transport from California. The NOAA model indicates a pool of ozone moving eastward just west of Yuma. By this afternoon, we can possibly see some elevated values. However, by tomorrow, ozone will likely spike and hit the mid Moderates. Check back tomorrow for more. Until then, have a good day! -P.Patel
