You will get the lollis to 10-12 up there. No mixing. Just lack of precip. I said a few days ago these monster rate events often seem to fizzle and those with good temps waste hours getting spitting snow while those getting yellow-banded are at 35 degrees.
This feels like a very sloppy 4-10 across the area kind of thing to me. A pretty classic event for the region, actually. We don't get these types of standard-issue events much anymore.
ICON maps on TT do not show mix. So when it shows rain over your house with temps in the upper 20s, that's either sleet or ZR. I assume that is what its causing the confusion.
