Friday forecast: Triple digits are back

PHOENIX – Phoenix residents may see their first 100 degree day of the year on Friday. On average between 1981 and 2010, the first triple digit day has been May 2. The earliest recorded by the National Weather Service was March 26, 1988, and the latest October 27, 2016.

Friday is also an Air Quality Index Action Day in Phoenix. This means the air quality range is unhealthy. The AQI is expected to be 101, which is unhealthy for sensitive groups. Thursday was moderate at 84 AQI. Weather conditions and ozone levels are to blame.

This means you will want to stay inside and limit activity if you are an active adult or child; have a lung disease; or have asthma.

Apache Junction, Maricopa, Pinal Air Park, Pinal County, San Tan Valley, Stanfield and Tucson all have an ozone high pollution advisory on Friday, too.

To help with air quality during an action day you can set your air conditioner higher; choose to carpool or use public transportation; and limit the use of household and gardening chemicals.

Temperatures in Phoenix will include a high near 98 and a low of 69. The sun will be out but there will be east winds around 5 mph in the morning and some calm wind later at night.

It will be a sunny day in Flagstaff with a high of 73 and a low of 39. An east southeast wind will range from 5 to 13 mph which will become south southwest by the afternoon. Later in the evening the wind will change to the west southwest at 5 to 11 mph.

Glendale will be sunny with a high of 98 and a low of 67. Five mph northeast winds will be calm as the day goes on. Sunny skies with a high of 99 and a low of 68 take over Yuma. Northeast winds around 5 mph will turn into south southwest winds by the evening.
