Some of the forecast soundings for the HRRR more closely resemble the GFS, with a razor thin above freezing layer where sleet is depicted. Normally for our area, I wouldn't underestimate how much sleet will fall, but there are some factors in this storm that have me believing it could easily trend towards higher snow amounts and higher freezing rain amounts, with the extent of the swath of sleet being a bit overdone (ala what the GFS has been showing). Historically, I'd want to hedge towards the NAM doing a better job of handling the northerly extent and depth of the warm tongue, but just the depth and height of the melting layer depicted have had me a bit suspicious of how much sleet will actually fall. The fact that some sleet is mixing a little ahead of forecast in some areas has me wondering if there will be an earlier switch to snow.
Honestly, though, I'd not be surprised if it goes the opposite way and the extent of freezing rain is much more northward. This is the type of nightmare to forecast the makes me glad I veered away from the professional forecaster route. Much more fun to track when you've got nothing at stake
