TUCSON, AZ (KOLD) - Dry air from the northwest is pushing back on the monsoon today. While the air will be muggy at the surface a little bit of dry air in the upper atmosphere will limit the number of monsoon storms in Tucson with better chances of storms in Santa Cruz and Cochise County. The storms that do form will slowly move to the  south-southeast.  Even with less storms in the skies, flash flooding is still a threat with slow moving storms.  It just takes that one storm to cause damage and get people talking. 

Hurricane Dora spinning off the west-central had a rough night.  A powerful Category 5 hurricane on Thursday, she weakened to barely a Category 1 Friday morning.  However, she still has enough punch to initiate a tropical moisture surge that will travel straight up the Gulf of California into Arizona this weekend.  Warm, tropical air is very unstable.  The sun's energy will kick start afternoon storms with outflow from those storms continuing the action into the evening hours both Saturday and Sunday.

Dora will die out off the west-central coast of Baja California over the weekend.  The remnant circulation will continue to enhance the warm, moist monsoon southerly flow into Arizona next week, along with a weak area of high pressure anchored to the east of the state.  Monsoon storms are expected in the skies all week long.
