Arizona weather stays high and dry with lack of rainfall
Feb. 12, 2018
Halfway into February, the Phoenix area typically sees around three inches of rain, but this year only half an inch is expected, putting pressure on the state’s drought.
“Arizona is going to be persistently in drought throughout this springtime,” ASU climatologist Randy Cerveny says. “That means we’re not going to get any more snow cover up in the Rim country, which has big implications on our water supply and also to wildfire.”
The chances of rainfall decreases as we approach springtime. Cerveny explains the high stagnant pressure system that’s located in the west has forced all the storms to travel northwest. A current storm is coming from the west, but the moisture is coming from the southwest.
“This very persistent La Niña pattern is slowly breaking up,” Cerveny says. “That’s some good news because if it continues to break up into the spring and summer, it is possible we will get into an El Niño situation next winter.
The lack of rain is predicted to be consequential for the upcoming drought. As Cerveny says, the biggest effects will be seen on our water supply and the number of wildfires.
Starting Monday, the Valley is expected to be blanketed in clouds all week with the greatest chance of rain happening on Wednesday night into Thursday morning.
