MOST ACCURATE FORECAST: Big warm-up in the Valley this week!

PHOENIX — High pressure is making a comeback this week, sending temperatures soaring once again!

Valley highs are back in the 70s and could even flirt with the 80s by this weekend. That's around 10 degrees above normal for the end of January.

Mornings will still be chilly. Expect overnight temperatures to drop into the 40s across the Valley all week.

We'll see some clouds moving through at times, but there are no chances for rain as we head into February.
