Is it Summer Yet?

Weather / Air Quality

The triple digits are not far away but have been postponed for another few days. Air quality will improve as the wind subsides.
Today's Air Quality Forecast
The cold front responsible for kicking up winds and dust yesterday has cleared the state. All monitors yesterday recorded PM readings in the Moderate category. Elevated readings and some haze are still noticeable this morning, but breezy winds by afternoon will help disperse dust. Also, enough moisture and instability exists for light showers to develop over the higher terrain north and east of Phoenix during the afternoon. A cooler air mass has moved in and high temperatures in the upper 70s today are about 10 to 15 degrees below normal for early May. Temps will be somewhat slow to recover as Arizona remains under the influence of a broad area of troughing. Air quality improves by tomorrow, but ozone will continue to range in the upper Good to lower Moderate categories.
