Arizona will be a contradiction of weather terms over the next few days as an unusual weather system passes through the state through Sunday.

Rain was falling in Phoenix, hail fell in the East Valley, a snow advisory has been issued in the north and a wind advisory in the southeast. Tucson and Nogales face hazardous fire conditions.

There is a 30 to 60 percent chance of rain on Friday, said Jaret Rogers, meteorologist for the National Weather Service.

Rogers also said that hail hit the southeast Valley on Thursday afternoon. Chandler Heights was hit with marble-sized hail and Gilbert and Gila Bend received pea-sized hail.

"Some of these thunder storms are producing hail, but not severe hail. Expect continued storms into the evening," Rogers said.

The chances of rain will decrease into Friday night, with some chance of lingering isolated showers through Saturday. With the cloud cover comes comfortable temperatures: 83 degrees on Thursday, 72 degrees on Friday and 78 degrees on Saturday.

The unusually cool and rainy weather conditions are because of an unseasonably strong low-pressure system coming in from the Pacific Northwest, Rogers said. It is similar to weather systems that occur in the winter, bringing increased moisture and precipitation to the Valley.

Rogers said that temperatures should rise by Sunday, with a gradual warm up and mercury hitting the mid to upper 90s by the middle of the week.

Northern Arizona will also experience unseasonable conditions over the next few days. The National Weather Service issued a snow advisory for Flagstaff with three to five inches of snow predicted Friday.

A red flag warning was issued for the Tucson and Nogales areas. The warning was issued by the National Weather Service as a "heads up" for possible hazardous fire conditions.

The National Weather Service also issued a wind advisory south of Casa Grande.
