Now is the time to prepare, ahead of a major winter storm headed our way!
Valley highs will only reach the mid 50s and they'll stay in the low to mid 50s for the rest of the week. That's putting us 15 to 20 degrees below normal for this time of year.
Then, the biggest winter storm of the season will move into Arizona late tonight into Thursday, with rain and snow expected through Friday.
Thursday will be an ABC15 Weather Action Day because rain will likely impact your commute in the Valley and the heavy snow falling up north will bring traffic to a complete halt in many areas.
Forecast models are now showing the potential of one to two feet of snow in Flagstaff and potentially more than two feet in a few spots along the Mogollon Rim!
This will likely be a record setting snow storm.
Flagstaff's snowfall records are 10 inches for Thursday, February 21st, set back in 1944, and 9.7 inches for Friday, February 22nd, set back in 2008.
Prescott, Payson and Show Low's records range from 1 to 6 inches on those two days, so they will likely be easily broken, too.
Here in the Valley, we could see a half an inch to an inch of rain Thursday into Friday morning, which may challenge records too if we get enough at Phoenix Sky Harbor.
Thursday's rainfall record in Phoenix is 0.73 inches set in 1973 and Friday's record is 0.45 inches set in 1913.
We're also tracking the potential of the coldest February 22nd ever recorded in the Valley. Our forecast high is only 51 degrees. That's more than 20 degrees below normal. The record coolest high for that date is 54 degrees set 122 years ago back in 1897.
We'll start to warm things up a bit as we dry out this weekend. Look for highs back in the low 60s by the start of next week.
