PHOENIX — Winds are gradually backing off as temperatures drop into the 50s overnight.

It's going to be a beautiful day in the Valley on Thursday as highs hit the upper 80s.

Then, high pressure will build in and send temperatures soaring into the weekend.

Phoenix will hit the upper 90s on Friday and heat up into the triple digits over the weekend.

Highs will hover around 105 degrees Saturday, Sunday and Monday with early morning lows in the 70s.

Temperatures that high will put us in record territory.

Sunday's record is 107 degrees, set in 1937. Monday's record is 106 degrees, set in 1997. We'll likely be within a degree or two of both of those records.

Heat this intense is happening a bit sooner than normal this year, too.

On average, Phoenix sees its first temperatures each year at 105 or hotter around May 22nd.

As wind die down, air quality will get worse. Ozone pollution will build up in the Valley and our air could become unhealthy for anyone with a respiratory condition on Friday, Saturday and Sunday.

The Arizona Department of Environmental Quality has issued High Pollution Watches for Ozone pollution on those days, so plan on limiting your time outside if you have asthma or COPD.
