Phoenix residents encountered rainy conditions to kick off the month of June.

According to the National Weather Service, Phoenix set a new daily rainfall record for June 1 with about a quarter of an inch. The old record was 0.2 inches set in 1914, according to Weather Service data.

National Weather Service meteorologist Mark O’Malley said accumulation varied widely across the Valley in the latest storm – some areas north of Phoenix got nearly 2 inches of rain.

Phoenix Sky Harbor International Airport ended up with about a third of an inch of precipitation.

“Now, that’s not that much, but it is actually a record for this time of the year," O’Malley said. “We typically don’t see rainfall in the beginning of June.”

The monsoon doesn’t start until mid-June. O’Malley said long-range forecasts show there is about a 40% chance the Valley will see above-normal rainfall this summer.

“There’s decent prospects out there. But even in some of the wetter monsoons, there’s still localized areas that get missed out, and that’s just the nature of thunderstorms during the summer,” O’Malley said.

More rain would be welcome. In an average year, Phoenix has had about 2.9 inches of rain. But so far this year, Sky Harbor has had just 1.2 inches.

“By the time we get to the middle of the week, we’re looking at temperatures back into the middle to upper 90s and then by the end of the week, we’re back between 100 and 105 degrees, which is right around normal for this time of year," O’Malley said.

The National Weather Service recommends people “plan accordingly” when encountering rain or wind.
