It's that time of year when all the great Phoenix winter weather bragging begins to fade away, and we enter the sweat zone.

The forecast is calling for Phoenix to break the 90º mark for the time this year on Wednesday (April 22nd) and 100º on Sunday (April 26th).

If the forecast pans out, it will only be four days between the first 90º and 100º days. This would tie as the third shortest time-space between these two milestones. In 1994, they were just one day apart (April 15th and April 16th). And in 1988, they were three days apart.

The thirty-year average is just over a month apart, with the average 90º day being March 31st and the first 100º day on May 2nd.

On the other hand, the furthest apart these two events have been was 83 days which occurred in 1904 (Feb 24th & May 17th) and 1972 (Mar 5th - May 27th).

Stay cool!

Get ready for a significant drop in high temperatures! A storm system currently off the coast of California will move into Arizona Wednesday through the end of the week. This storm will result in a chance of rain for the Valley, but the big story will be the much cooler weather!

High temperatures by Thursday are forecast to be in the upper 60s! Keep in mind, the average for this time of year is 83º!

If the forecast pans out and the high temperature stays in the 60s, it will be the first time since 2012 that we have seen a high temperature below 70 degrees during the month of April! Since 2000, there have only been ten days in April with high temperatures below 70 degrees.

If you don't like the cooler temperatures, don't worry, highs are forecast to rise back into the 80s this weekend.
