Highlights
- Phoenix faces a 30 percent chance of thunderstorms Thursday night, with storm chances continuing into Saturday morning.
- Moisture from Hurricane Marie is driving the activity; the storm itself is not expected to make landfall.

Moisture from Hurricane Marie is pushing into Arizona, bringing a 30 percent chance of thunderstorms to the Phoenix Valley Thursday night and elevated humidity through the weekend, AZFamily meteorologist April Warnecke reported.
Thursday's Valley high reaches 103, with a slight chance of afternoon and evening storms before the overnight window opens up. Friday afternoon looks dry, but a 20 percent chance of storms returns Friday night into Saturday morning. The heaviest rainfall is expected over Southwestern Arizona and Southern California. The storm itself is not expected to make landfall and continues to push to the northwest.
Sunday and Monday look dry for the Valley, with mountain thunderstorms possible over the holiday weekend. Temperatures rebound sharply: 102 Saturday, 104 Sunday, and 105 on Labor Day. Maricopa County's weather outlook notes that higher terrain north, east, and southeast of Phoenix would be favored for scattered storms with localized heavy rainfall during the active period.
The pattern is consistent with what AZFamily reported Wednesday, when Warnecke flagged a 30 to 40 percent chance of rain between Thursday night and Saturday morning in Phoenix as Marie's moisture pushed inland.
Warnecke said the newsroom is monitoring for rain chances potentially by the middle of next week.
