Forecast Discussion:

Satellite imagery this morning (Friday) continues to show the presence of a disturbance camped out over northwestern Sonora, Mexico. Radar also shows rain showers in Sonora. This disturbance will continue to be a point of interest today and through potentially Sunday, as forecast models indicate that it may stick around in the area. Primarily, it will provide daily thunderstorm and rain chances for southeastern Arizona.

Then by Monday, the disturbance will finally move off to the east as a much larger low pressure wave migrates over the Mountain West. However, this wave itself may keep rain chances in the forecast for southeastern Arizona Monday and Tuesday.

Air quality-wise, PM10 (dust) has been running relatively low this week. The main thing to note is brief bumps in PM10 in the evenings from local activity. Looking ahead, these general trends look to continue, unless the Douglas area sees rain; then, PM10 should run even lower.

Overall, PM10 will remain in the Good Air Quality Index category each day this week.

Check back on Monday for the latest!
