FLAGSTAFF, AZ (3TV/CBS 5/AP) -- This May has been somewhat of an anomaly for Arizona with late-season snowstorms hitting the Flagstaff area and multiple days of below-average temperatures in Phoenix.
That trend continued as a storm moved through the state Wednesday night into Thursday morning.
Widespread rain began falling in the Phoenix area around midnight. Amounts are light, generally between a few hundreds to a tenth of an inch, but it was enough to slick the Valley roads ahead of the morning commute.
According to the National Weather Service, Sky Harbor picked up .06 inch of rain from the early morning showers.
The storm, at least in the Valley, tapered down by 5 a.m. with skies gradually clearing after sunrise.
The storm will help keep the Valley with below average temperatures with a high of 78 degrees, 19 degrees below normal.

The National Weather Service says the heaviest snow is expected from late Wednesday night through early Thursday morning in Flagstaff and other elevations above 6,500 feet, while the Arizona Department of Transportation says “challenging driving conditions” are likely during the Thursday morning commute.
Snow totals thus far in northern Arizona:
• Flagstaff Airport: 2"
• Ash Fork: 1"
• Kachina Village: 2"
• Williams: 2"
• Bellemont: 2.8"
The Flagstaff area will be in a Winter Weather Advisory until 11 a.m. as the storm passes through.
ADOT says it has 67 plows on stand-by to take care of all of the roads in the North Central District, which would be I-17, I-40 and the highways all the way down through Payson.

The department says up to 4 inches of snow are expected in Flagstaff, likely affecting travel on Interstates 40 and 17 and U.S. 89. Snow is also expected along State Route 260 between Payson and Heber.
The City of Flagstaff usually has its snowplows and equipment in storage for the year but with the anticipation of a few inches of snow overnight, there are about 10 workers and plows on stand-by.

As soon as the first snowflake falls, they will dispatch the crew to keep the main streets in town clear and ice-free for the morning.

“I’m a fourth-grade teacher and it was crazy to not be in class for a whole week after the last storm. Now for us to be almost in June and have snow flurries and not get to be outside with the kids and have to be inside is hard. We want to be out and enjoying the fun summer,” said Katharine Lemcke, a Flagstaff teacher.
