Monsoon storms brought a little bit of precipitation to the Valley this week. But, conditions remain abnormally dry for this time of year.
National Weather Service meteorologist Isaac Smith said since the start of monsoon season on June 15, Phoenix Sky Harbor International Airport has had only about 0.2 inches of rain.
“So it’s really not much rainfall at all for us around here. Our normal rainfall up to this point would actually be about 1.57 inches in Phoenix, so we are well below normal for the current monsoon season,” Smith said.
Smith said the next few days could add to Phoenix’s rainfall totals.
“We’re going to have plenty of rain chances through the next week,” Smith said. “It looks like those chances start to ramp up more as we head into the first part of next week, climbing upwards of 40% to 50%.”
Gabriel Lojera is a meteorologist with the agency in Phoenix.
“It’s looking like, more likely, that it’s gonna be on Monday and Tuesday. Those are gonna be the best days for the best chances for thunderstorm activity here in the Phoenix area," he said.
Lojera says temperatures will still remain high in the lower 100s for the week.
The U.S. Drought Monitor shows drought conditions have improved just slightly in Maricopa County this monsoon season, but the whole county remains in a severe or extreme drought.
Thunderstorm activity will again favor SW Arizona today, where strong to severe storms will be possible this afternoon and evening. Most activity will remain west of the Phoenix metro, but chances still range from 15% in the east Valley to 30% in the west Valley. #azwx #cawx pic.twitter.com/elKNL4G8Nt
