Looks like we are in for a slow-moving storm that will bring regular snow over the next few days. The earlier model runs had a major precipitation event for tonight. Now, we are looking a few inches of snow now and then through Saturday. When the storm has passed, we should have a nice blanket of snow that is 7-12 inches deep. I think it will start after sundown tonight, which matches the National Weather Service. The commute tonight could be messy. I think I will blog about the different winter weather notices the NWS uses.

The National Weather Service has issued a Winter Weather Advisory for the Flagstaff area.
