Forecast Discussion:
An active weather pattern will be in store for the Southwest this week and weekend. Initially (today and Thursday), high pressure will try to retain some influence over the region. That's why daytime temperatures are near110°F. However, a large low-pressure pattern will take shape over the West towards the end of the week. This new pattern will evict the high pressure and cause highs to back away further from the 110° mark. Daily breezes are also expected, with strongest winds expected Friday through Sunday.
Air quality-wise, the winds from the changing weather patterns are expected to help reduce ozone in central Arizona. Therefore, ozone levels are forecast in the Good AQI each day.
However, on the windier days--namely Friday through Sunday--dust may be possible, particularly for dust-prone areas. We can also expect daily, elevated PM10 (dust) and/or PM2.5 (smoke) levels from local activities.
Check back tomorrow for the next update!
