Forecast Discussion:
Sky Harbor officially saw its first 100-degree F day of the year yesterday. In fact, the high temperature reached 102 degrees F, which tied the record high for the day. Ozone sat in the upper end of the Moderate Air Quality Index (AQI) category throughout the weekend. Now, let's talk about what's in store for this week...Weather maps and satellite this morning reveal a large low pressure wave stretched along the West Coast. Over the few days, this wave will close into a circulation and slide southward along the California coastline. Then by Thursday, it will edge its way into Arizona. Another smaller wave will affect Arizona on Friday.
Weather-wise, this week will be a breezy one. The active weather pattern will support southerly or south-southwesterly winds each day, today through Friday. Temperatures will also back away from the 100-degree mark, with highs bottoming out in the upper 70s on Thursday. Skies should remain mostly or partly sunny.
Air quality-wise, the winds will have a plus and a minus. The plus is that winds are expected to help limit ozone levels, preventing any significant local build-up. Moderate ozone levels are possible on days with the lighter winds. The minus is that winds will be strong enough to cause dust. In particular, today and Thursday currently look to have the most widespread breezes and therefore, the greatest potential for dust.
Hourly forecast PM10 (dust) levels have thus been increased for the afternoons, particularly today and Thursday. Moderate PM10 levels will be possible several days this week. Industrial areas south/southwest of Phoenix will also likely see the highest AQI for PM10, since they often see elevated PM10 levels in the mornings.
Lastly, PM2.5 (smoke) levels should generally follow PM10 trends.
Check back tomorrow morning for the latest!
