PHOENIX — Another winter storm is on the way!
Low pressure is moving through California now before moving into Arizona Tuesday night.
It's bringing a big dose of cool air, rain, higher terrain snow and very high winds.
The Valley will be under a Wind Advisory Tuesday evening through early Wednesday morning. Watch out for wind gusts near 45 mph!
For northern and eastern Arizona, a High Wind Warning is in effect Tuesday night into Wednesday morning. Damaging wind gusts of 60 mph are possible there, so watch out for blowing dust, blowing snow, and dangerous cross-winds.
Be sure to secure loose objects and Christmas decorations before the storm arrives.
With the potential for damaging winds in the Valley Tuesday night, we will be in ABC15 Weather Action mode.
We will see rain move through too as the cold front with this storm moves through. The key timing on that will be between 10 p.m. and 3 a.m. for the Phoenix metro area.
We could see a few spotty showers as early as Tuesday morning though with moisture streaming in ahead of this storm.
We're expecting anywhere from a trace to a quarter of an inch of rain across the Valley.
Up north, a Winter Storm Warning is in effect late Tuesday night through Wednesday morning. This is mainly for areas along the Mogollon Rim, in the White Mountains, along the Kaibab Plateau and in higher terrain spots of northeastern Arizona above 6,500 feet in elevation.
Snowfall totals will likely be in the 4 to 7 inch range in many of these spots, including in Flagstaff.
This system will also bring in very cold air and drop temperatures in the Valley into the upper 50s to low 60s Wednesday afternoon.
Overnight lows will plummet into the upper 30s to low 40s Thursday morning.
Then, we'll slowly rebound for the rest of the week. Valley highs will be back in the mid 60s by Friday and upper 60s by this weekend.
2021 Rainfall totals:
Sky Harbor Official Rainfall: 5.93" (-0.85" from average)
Valley Average (Phoenix Rainfall Index): 7.48"
