The NAM is a total grab bag of wintry elements. A heavy burst of snow for all to start, 3-5" or so, then the mid levels warm above freezing from around 04z to 15z Sunday. QPF during that period is around .7" to .8" for most of us. Peeking at soundings, it seems like sleet would prevail north of 84, with ZR to the south. For reference, the sleet-to-liquid ratio is typically 3:1, and freezing rain accretion averages around 0.7:1, though that varies widely. Based on all that, and with the NAM being among the iciest guidance, a catastrophic event seems unlikely. @gravitylover land would be the ice storm epicenter with perhaps a half inch of accretion.
