MOST ACCURATE FORECAST: Big warm-up across Arizona this week!

Posted
and last updated

PHOENIX — After a cold and wet start to the month, temperatures are warming up across Arizona this week.

Phoenix reached 70 degrees for the first time this year on Tuesday and it's about to get even warmer.

Valley highs will climb into the mid 70s on Thursday, Friday, and Saturday, putting us a few degrees above normal for this time of year.

Overnight lows will get milder too, dropping into the 40s tonight before hitting the 50s by the end of the week.

A storm system is passing to our north today, bringing a few isolated rain and snow showers to northern Arizona (mainly north of I-40). Otherwise, our forecast will stay dry statewide through the rest of the week.

More clouds will move in Friday and Saturday ahead of back-to-back storms that could bring rain and snow to Arizona Sunday, Monday and Tuesday.

Snow levels look relatively high with both of these storms, only dropping to around 7,000 feet. So we'll see more of a rain-snow mix across northern Arizona with limited snow accumulation in the high country.

Here in the Valley, scattered showers will move in on Sunday with another round Monday night into Tuesday morning. Early estimates show up to a half an inch of rain in some Valley neighborhoods over those three days.

Stay tuned for more details as we get closer.
