Summarised from 2 outlets · 5 reports · Updated 29 Oct, 13:15 · Archive

Two storm systems will bring rain, thunderstorms and possible flooding to the Phoenix area from Friday through Sunday.

The Phoenix area will see a significant weather change this weekend as two storm systems move into Arizona. Through Thursday, conditions remain mostly warm and dry with highs in the mid-to-upper 80s.

Friday marks the arrival of the first system, with rain chances increasing sharply from morning through afternoon. Both outlets report a 70% chance of precipitation on Friday. Azfamily reports that rainfall could be moderate to heavy at times, with embedded thunderstorms capable of producing brief, intense downpours. Valley rainfall amounts are likely between a half inch and an inch, though thunderstorms could produce up to 2 inches in some areas. A Flood Watch has been issued for the Valley from 6 a.m. to 6 p.m. on Friday. Highs will drop to around 76 to 79 degrees.

Saturday should bring a brief respite with mostly cloudy skies and highs near 78, though a few lingering showers are possible, particularly over higher terrain. A stronger system arrives late Saturday night into Sunday, bringing widespread rain and additional flooding concerns. Outlets report 70 to 90% chance of precipitation on Sunday, with steady, light to moderate rain continuing through the day. Azfamily notes that with soils already wet from Friday, additional rain could compound flooding problems. Conditions dry out Monday with drier weather returning Tuesday.
