Onset is in 72 hours. Midlevels have trended even colder on the 12z gfs. Ops seem locked in with some sort of mix of wintry precip through much of the area.
Many of us could stay below freezing all day on Sat. Especially the northern tier. It may be a light event but the duration looks unusually long. Could be the biggest event of the year for many of us. That isn't really saying much though. LOL
