PHOENIX -- A storm system gathering in Canada is dropping toward Arizona, and by Thursday afternoon, we have a chance to see scattered showers developing out ahead of that storm.
This storm looks rather wet. The latest models are indicating we could see between ½” and an inch of rain in metro Phoenix by Sunday morning. As this storm develops, we think we’ll see precipitation come in waves; it won’t be a non-stop deal starting Thursday night.
In the high country, most of the initial precipitation will be rain as the snow level is going to start somewhere around 7,500 feet. However, Friday night some colder air is being pulled into the system and it looks like we could have a decent snow from the White Mountains along the Mogollon Rim to Flagstaff. It’s hard to put a number on the snowfall yet except that if the timing is right and it gets cold enough, fast enough, it’s likely the Weather Service will be issuing advisories for the snow.
Temperatures are, of course, headed down. We’ve been in the 70s the past couple of days and by the weekend, some Valley locations may not get out of the 50s! And when the rain gets here, it’s pretty welcome. The last measurable rain at Sky Harbor Airport was on September 9th, over two months ago.
Remember the AZ Weather Axiom: The more a storm is anticipated, the less likely it is to arrive. :-) rain not a lock....yet— Royal Norman (@royalnorman) November 20, 2013
