PHOENIX — Powerful storms swept through the Valley, bringing heavy rain and hail to some areas on Wednesday night. Here are the latest updates we're tracking as this storm system moves across Arizona: As of 8:40 a.m. 38 flights at Phoenix Sky Harbor International Airport have been delayed.

Widespread rain Thursday night with occasional showers continuing into Saturday with a slight chance of thunderstorms through Friday.

The FAA issued a regional ground stop for Dallas Fort Worth International Airport until 11:15 a.m. CST. Any flights departing for DFW from the impacted airports will be delayed at least until the ground stop expires. The order applies to most of the southeastern and southwestern U.S., including major hubs Atlanta, Charlotte and Phoenix.

The bulk of the rain is expected to fall on Thursday and Friday, but it could continue into Saturday, particularly in San Diego. There, the storm could linger and bring additional rounds of rain because of what meteorologists call “wraparound moisture,” which is additional precipitation that arrives on the back end of a storm.
