MOST ACCURATE FORECAST: Back-to-back storms to start the week

Posted
and last updated

PHOENIX — After a gorgeous and warm Super Bowl weekend, we are tracking back-to-back winter storms to start the new week.

The first storm moves in tonight, bringing rain showers to the Valley overnight into Monday morning.

Parts of the Valley could see between a tenth and a quarter of an inch of rain that could impact your morning commute.

So, Monday will be an ABC15 Weather Action Day. We expect rain and snow to impact your outdoor plans and travel plans across Arizona, so take action to get ready for it.

Snow levels will drop to around 5,000 feet on Monday and we could see 1 to 3 inches of snow in spots above 6,000 feet in elevation, like Flagstaff.

A Winter Weather Advisory is in effect along the Mogollon Rim through Monday night.

A second stronger storm moves in on Tuesday, so we'll be in ABC15 Weather Action mode again.

This second storm will be cranking up winds with gusts topping 40 to 50 mph across Arizona. Even here in the Valley!

Snow levels will plummet too, falling to near 3,000 feet by Tuesday night.

The Valley only looks to get light rainfall with this storm, at around a tenth of an inch. But, we could see some snow flakes make it down in our foothills which sit at a higher elevation.

Our highest elevations, like Flagstaff, could pick up an additional 6 to 12 inches of snow on Tuesday which will greatly impact travel on our high country roads.

Take action now to adjust or cancel your travel plans in the high country on Tuesday as roads will be snow-covered and blowing snow could significantly reduce visibility.

Winter Storm Warnings will be in effect across the Arizona high country throughout the day Tuesday and into Wednesday morning.

These back-to-back storms will also bring in some much colder air this week.

Valley highs will be nearly 20 degrees colder on Monday, falling into the upper 50s.

We'll stay in the upper 50s to low 60s for much of the week with overnight lows plummeting into the 30s on Wednesday and Thursday mornings.

We could see even freezes in parts of the Phoenix metro area on Thursday morning.

Our forecast will dry out again toward the end of the week, but we're already tracking another storm that could bring more rain and snow this weekend.

Stay tuned for updates as we get closer!
