Showers, storms expected across parts of Ariz.

Posted: Updated:

PHOENIX -- A weak system tracking into Arizona Thursday night through Friday is expected to bring isolated showers and thunderstorms to the high country. Most of the Valley is expected to dodge the wet weather.

The atmosphere is pretty dry, so a lot of the shower activity seen on Doppler radar Thursday afternoon was evaporating before it hit the ground.

As the system shifts east through the state, the Valley has a slight chance of sprinkles through Friday morning. This is mainly north and east of Phoenix.

Once the system moves into New Mexico Friday afternoon, wrap-around moisture and cold air aloft could produce a few isolated showers or storms across eastern Arizona.

Snow levels are expected to drop between 8,000 and 6,000 feet.

Localized gusty winds may also develop.

Behind the system, high pressure builds in for the weekend, kicking off a warm-up.

A dry cold front will sneak through the area on Saturday, increasing winds statewide.

For Friday, expect a morning low of 53 degrees in Phoenix under partly cloudy skies. The afternoon should see a high of 79 degrees under sunny skies.

For Saturday, look for sunshine with a high of 85 degrees and breezy winds.
