MOST ACCURATE FORECAST: Storm set to bring rain and snow to Arizona this week

Posted
and last updated

PHOENIX — It's been a beautiful weekend in the Valley as temperatures have been in the upper 60s to lower 70 degrees. However, changes are on the way as a storm system moves in bringing rain and snow to the state.

Rain and snow chances will start late Sunday night in northwestern Arizona, but ramp up Monday morning through Wednesday across the High Country as the core of this next storm tracks right through our state. The storm will continue to bring snow to the White Mountains and eastern Arizona through Wednesday and Thursday.

A Winter Weather Advisory is in effect for portions of Mohave, Yavapai, and Coconino Counties. Areas above 4,000 feet in elevation could see two to five inches of snow, and the higher peaks above 6,000 feet could see six to eight inches.

Heavy snow bands are likely to form along the I40 corridor from Flagstaff to Kingman. Flagstaff is expected to receive 3-5 inches of snow, with totals closer to 6-8 inches near Williams. Travel will be treacherous at times. Be sure to be prepared by having a full tank of gas, an emergency kit in your car, and someone who knows where you will be traveling to and from.

Isolated showers are possible in the Valley on Monday, Tuesday, and Wednesday. Right now, it doesn't look like much rain, but some neighborhoods could see up to a tenth of an inch, with slightly higher totals in the northwest Valley and up toward Anthem.

The rain chances will be higher on Monday and Wednesday, with a slightly lower chance on Tuesday as the low-pressure tracks over the Valley.

As of Sunday, January 26th, Phoenix had been without measurable rain for 157 days in a row, the second-longest dry streak on record.

If we don't get any measurable rain at Sky Harbor by Wednesday, we could tie or break the 1972 record of 160 dry days in a row.

The storm is set to bring snow to eastern Arizona and the White Mountains by Thursday.
