Forecast Discussion:

Today and Saturday, a wave of low pressure will graze the Southwest and result in stronger winds over the region. During the day, winds near the ground are expected to be elevated around 10-15 mph.

Then on Sunday, high pressure will begin to build over New Mexico and slowly expand over Arizona through Monday and Tuesday. In general, winds are expected to be light each day, with afternoon breezes out of the west.

By Wednesday, the high pressure will center itself near the Four Corners region, increasing thunderstorm chances in southeast Arizona. However, winds are currently not looking to be favorable for thunderstorm movement toward the Valley. Light winds are expected on Wednesday as well.

Overall, the dust risk is Low each day through at least Wednesday. But we'll continue to monitor the potential for dust-bearing outflows moving into the Valley.
