After record-breaking heat last week hitting 108 degrees in Phoenix, temperatures plummeted Sunday with a high of 74.

It was a 34 degree swing — the biggest three-day cool down in May the city has ever seen, according to the National Weather Service.

In Phoenix, three-day temperature drops higher than 20 degrees come few-and-far-between in May.

Since 1896, it’s only happened 24 times.

The last time the Valley saw a similar drop was in 2008 when temperatures dropped 30 degrees, from 108 to 78 between May 20 and May 22, according to NWS.

Temperatures themselves were chilly for early May. The 74 degree high approached the record low for a high, which was set on May 7, 1965 when temps only reached 70 degrees.

While temperatures won’t break any records in the next few days, according to NWS meteorologist Matthew Hirsch, they will be unnaturally cool.

Lows in the Phoenix area hit 64 degrees Sunday accompanied by 23 mph winds. That cool trend should continue throughout the week, with cooler weather and rainy days ahead. 

Isolated showers were reported throughout the region leading into Sunday and continued in eastern Arizona.

“For much of Arizona, there was not much rain today,” Hirsch said.

But chances of rain and storms should pick up Monday, Hirsch said, with a 30 percent chance of rain Monday evening and a 40 percent chance Tuesday.

Temperatures will stay below average through the start of the week, according to Hirsch.

Highs Monday and Tuesday will range in the high 70’s and low 80’s, while lows will be in the mid-to-high 50’s.

The forecast for Monday calls for highs between 77 to 81 degrees. Lows are expected to be between 52 to 58 degrees, with chances for thunderstorms throughout the night.

The high Tuesday will be around 73 degrees, with a low that morning around 57 degrees.  Things will start to heat up Wednesday afternoon with an expected high of 78 degrees and lows around 58 degrees.

The rest of the week will follow a warming trend with few winds, Hirsch said.

“It doesn’t look all that breezy,” he said.
