High pressure aloft remained centered near northwest New Mexico on September 8th, resulting in a southeast flow that maintained a moisture supply across southeast Arizona. With weak winds aloft, storms moved slowly, producing locally heavy rainfall and locally strong downburst winds. Outflow boundaries from storms encouraged further development into the evening hours.
