I have no idea, all the Mets on Twitter seem to think once it changes over it will be all sleet. But the Hires NAM has the same progression, so I wouldn't totally discount it
The HRRR does seem to have a good handle on the sleet line right now and pushes it back south in an hour or two. A possiblity anyway, not sure that I would expect it
Something I never thought about, why do the obs often include mist while snow is falling? Like GSO obs currently read "light snow, mist". Is this to do with the visibility?
There really aren't any models showing precip before around 5pm, but also these overrunning events tend to start 2-3 hours earlier than modeled (at least as far as light flurry action goes)
