PHOENIX — Today will be the hottest day of the year so far in Phoenix.

Valley highs will hover around 106 degrees today, putting us more than 10 degrees above normal for this time of year.

We're also on record watch. Today's record is 107 degrees, set in 1937, and we'll likely be within a degree of that mark.

High pressure will keep daily highs in the low 100's as we move through the work-week.

Early morning lows will be milder too, only cooling into the low 70s.

Air quality continues to be an issue as winds stay light. Ozone pollution will build up in the Valley and our air will become unhealthy for anyone with a respiratory condition.

The Arizona Department of Environmental Quality has issued a High Pollution Advisory for the Valley again today and High Pollution Watches for Monday and Tuesday. So, limit your time outside if you have asthma or COPD, especially in the afternoon when ozone pollution will be at its worst.
