Warm week ahead; cool-down coming?

Posted: Updated:

PHOENIX -- The Valley of the Sun will live up to it's nickname in the week ahead, with warmer than average temperatures and plenty of sunshine. 

High pressure remains positioned over the desert Southwest, with temperatures forecast to peak Wednesday. We might see our first 90-degree high of the year on Wednesday, about two weeks earlier than normal. While decidedly early, it won't be a record if it happens.

After Wednesday, conditions turn breezy and cooler. Temperatures will drop back to the 70s for Saturday and Sunday, which is the vernal equinox, also known as the start of spring. This year's vernal equinox occurs on Sunday, March 20 at 7:21 p.m. EDT, which is 4:21 p.m. Arizona time.

While it's a bit too early to tell just yet, It's possible that our first week of spring could be a cool one with highs topping out in the 60s early in the week.

The warmer weather we're seeing right now might prompt fears of spring flooding, but the National Weather Service says that's not looking likely. Click here their latest water supply summary and hydrologic outlook.
