PHOENIX — We are headed into the hottest weekend of the year so far.

Valley highs are climbing into the mid 90s Saturday and into the upper 90s on Sunday, putting temperatures at around 10 degrees above normal for this time of year.

High pressure will build in again over the weekend. Triple digits are looking more unlikely now for Monday in most Valley neighborhoods, but it will be close. On average, Phoenix's first 100-degree day happens around May 2nd.

Air quality will also get worse with ozone pollution potentially reaching unhealthy levels over the weekend.

Ozone High Pollution Advisories have been issued for Saturday and Sunday in the Phoenix metro area. If you have a respiratory condition, like asthma or COPD, limit your time outside in the afternoon hours or you may have difficulty breathing.

By the middle to end of next week, another weak storm system will move in. Winds will pick and temperatures will drop, bringing Valley highs down into the upper 80s again by Thursday.

We could see a few isolated showers in parts of northern Arizona, mainly north of I-40, but the rest of the state will stay dry.
