PHOENIX — It’s been 110 days since we’ve seen measurable rain at Phoenix Sky Harbor. That’s the 15th longest dry streak on record.
But, that could change this week!
We are tracking a storm moving in from the Pacific that could bring rain to Phoenix for the first time since August.
The highest rainfall totals will be in southeastern Arizona with up to an inch expected. Here in the Valley, we could pick up around a tenth to a quarter of an inch of rain.
Most of the rain will fall early Thursday morning, but rain chances will begin late Wednesday night.
We’ll also see another slight chance of rain on Friday as a second storm system moves in from the north.
The snow level up north will drop to around 6,500 to 7,000 feet and we could pick up around one to four inches of snow along the Mogollon Rim and in the White Mountains.
Then, we’ll dry out again across Arizona this weekend.
While this week’s rain could finally put an end to our dry streak, it won’t be enough to end our worsening drought.
100 percent of Arizona is in drought right now, and 77% of the state (including the Phoenix area) is in Exceptional Drought — the worst drought category.
The long-term outlook over the next three months shows a good chance of drier and warmer than normal conditions across Arizona with La Nina in effect.
NOAA’s Climate Prediction Center says La Nina is likely to continue through the Spring of 2021.
So, although we may see a few storm systems like this one from time to time, we expect conditions here in Arizona will average out to be warmer and drier than normal through at least the first half of next year. That means our drought will likely get worse in the next few months.
