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)
Even accounting for the NAM being too far north I would be a bit concerned that this is what it's showing not too long after onset in the triad
Weenie phase 2 is here,just 30 minutes later!
Be careful with precip type maps! The NAM seems to be overplaying the ZR, this sounding for Raleigh area would likely be sleet, especially with that much lift.
