Forecast Discussion:
This morning, a low pressure wave over Arizona and New Mexico is providing some light breezes to the Phoenix Valley. For the most part, these winds should help to reduce PM10 (dust) and PM2.5 (smoke) from local activity. The only exception has been a localized area southwest of Phoenix downtown; this area has seen elevated PM10 and PM2.5 levels. The hourly graphs reflect these areas.Later this morning, and perhaps into the early afternoon, winds are expected to increase out of the north. But winds are not expected to be strong enough to cause any dust concerns. Then by the evening, more stagnant conditions should allow PM10 and PM2.5 to increase again.
After today, high pressure will be the general pattern over Arizona through Friday. As a result, daytime temperatures are forecast to warm up into the mid-70s by the weekend.
Light winds on Wednesday will allow PM10 and PM2.5 to become mainly locally driven. However, another breezy period will be in store for the Valley Thursday into Friday. Pockets of dust may be possible Thursday afternoon. But winds may help to limit morning PM10 and PM2.5 levels.
Lastly, another low pressure wave will approach from the west on Saturday. Pockets of dust may be possible in the afternoon. But mainly, PM2.5 is expected to increase from weekend activity.
