There is a winter storm warning posted for Flagstaff. It is below. But, what if it didn’t come together as promised. Is that even possible? The National Weather Service has the following forecast for downtown Flagstaff:

nwsforecastIf you add up the snowfall amounts from Wednesday to Thursday, the totals come to 7-14 inches. This is in the 1 inch of water range. I think this could happen and that it is important for the National Weather Service to project it. They are responsible for helping us prepare for bad weather. Hats off to them for being very active in the social media about this storm.

The problem is that this storm is heavily dependent on timing. The low pressure system needs to develop over Arizona at the same time that a burst of moisture makes its way up to Arizona from the tropics. After watching the computer models over the last few days, I am very tempted to side with AccuWeather‘s slightly lower forecast of 5-12 inches or even Wunderground‘s lower forecast of 5-8 inches. Most of the models are heading in the 3/4’s of an inch of water range which fits the lower predictions. Still, I am concerned that everything will come together, but over Eastern Arizona, not Central Arizona.

I recommend taking this storm seriously. It could be our biggest one for the season.

  1. […] you look back to my post from yesterday, it did not include waking up to over an inch of snow. So, the storm got a bit of an earlier start. […]
