PHOENIX - Tuesday was sunny and mild across Arizona. Temperatures hit the mid-70s in the Valley, but it was still a chilly morning in the upper 40s.
What To Expect:
Keep all-season clothing around, because we have more whiplash temperatures in store this week.
The Valley will fall back into the upper 40s Tuesday night, under clear skies.
Wednesday will be an even warmer day, with a high of around 78 degrees. Highs will keep hitting the upper 70s through next week, and possibly hit 80 degrees on Thursday and Sunday.
Temperatures will be running ten to fourteen degrees above normal through the end of the week. Record daily-high temperatures may be tied or broken on Friday and Sunday in the Valley.
Dig deeper:
This unseasonable warmth comes when we are just one week away from our coolest time of year, climatologically, in Phoenix.
Skies will stay sunny and dry across Arizona for the foreseeable future.
