PHOENIX -- The storm system headed toward Arizona looks like it’s going to be a little cooler and wetter than earlier forecasts.

While we’re still not expecting any rain around metro Phoenix, the chances for scattered rain and snow showers have increased for northern and eastern Arizona. We could see some of that precipitation Friday through Sunday, which would end nearly a month-long dry period for some locations in the high country.

In the Valley, Thursday is going to be a transition day. We’ll see a high of 80 degrees and then clouds will begin moving in.

Highs will be in the low 70s by Friday and in the mid-to-high 60s by the weekend, which is significantly cooler than previously indicated. That represents temperatures below average for the first time this year.

There has been no rain in Phoenix since Dec. 20, making Wednesday day 40 without rain. That’s not very unusual for the Valley.
