PHOENIX -- The end of the work week may include a little action from the monsoon, as a moist and humid air mass continues to pump into the eastern half of the state.

Thursday afternoon, rain stayed out of the Valley, but storms to the south near Casa Grande collapsed and kicked up dust during the rush hour. A Dust Storm Warning was never issued by the National Weather Service, but as a light brown cloud filled the sky, visibility at times was reduced to a half mile, with winds gusting up to 35 miles per hour, prompting a Blowing Dust Advisory.

Meanwhile, northeastern Arizona saw scattered storms. At one point, a Flash Flood Warning was issued for the city of Page in Coconino County. This came on the heels of a tie record for the wettest July in Flagstaff. A total of 7.58 inches of rain fell at the airport, matching the old record set in 1919.

Thursday night, storms across eastern Arizona are expected to end. In the Valley, overnight lows will only dip to the upper 80s and low 90s.

On Friday, storms may redevelop, but they will most likely be confined once again to eastern Arizona. A drier air mass is pumping into the western portion of the state, preventing storm activity.

In the Valley, storm chances are slim, but blowing dust could once again be a problem during the latter part of the day. We’re forecasting Valley high temperatures of around 105.

The weekend is expected to be drier, with partly cloudy skies in the Valley and highs continuing around 105.
