PHOENIX -- The National Weather Service has issued a Fire Weather Warning for most of Arizona today.

That warning is expected to go into effect in Phoenix and the surrounding areas at 2 p.m. Winds are expected to kick up this evening and tonight, gusting through the early morning hours.

There's also about a 10 percent chance of rain in the forecast. The best chance will come very early Tuesday morning.

Plan on a high of 83 in the Valley today, dropping to 76 tomorrow. After that, we'll begin warming back up as we head toward the weekend.

When will the mercury hit 100° this year?  Take a guess and you could win a new AC system from Ace Air.
