It's just too soon for this kind of heat.

About a month too soon, in fact.

The high temperature at Sky Harbor Airport reached 108 degrees by 4 p.m., Friday. That broke the record of 105 degrees set in 1989. According to the National Weather Service, the city doesn't see a temperature that hot until June 4, on average.

While such temperatures at this time of year aren't unheard of (the earliest date the city reached 108 degrees was May 3, 1947) they are ahead of schedule.

The heat was cranked up early in the day as the temperature reached 100 degrees by noon. By 1:45 p.m. it had reached 107 degrees.

The morning low could also prove to be record setting. If the temperature does not dip below 74 degrees before midnight, Friday morning's low of 76 would also set a record for the date.

Friday’s record high isn’t expected to be the start of an early-season heat wave, however. A low-pressure system is headed this way and could drop temperatures by about 30 degrees by the start of next week.

The Weather Service forecast high for Saturday is 95 degrees with strong winds, while Sunday’s high is expected to be in the mid-70s. Monday’s outlook even includes a slight chance of rain.

Temperatures aren’t expected to creep back above normal until the latter part of next week.
