I am truly going out on a limb here as this is nowhere in the National Weather Service forecasts, be it in the mountains or in the central Piedmont. At work late this morning, our in-house models started to create graphics that point toward a 'surprise' snow early Sunday morning...if you recall last Monday, that was a 1" or so forecast, and an unseen upper level low energized and gave ACA up to 5". It wasn't in anyone's forecast.
That same energy I'm seeing clearly moving out of eastern IA heading directly towards us, and models here showing overnight snows for ACA once again. More than that, that upper level low looks like it will hit the lee side of the Blue Ridge about 4am and rapidly create uplift for a strong burst of snow before and through sunrise in places like Charlotte and Greensboro.
In checking my NAM and GFS modeling, both have been holding steady for 1-2"...so all I know to do is say 'heads up' and don't be surprised if you wake up Sunday morning with more white stuff out there. And if it doesn't come to pass, we'll count our blessings.
