First was the NOAA f up. PM runs showed the line skipping north, leaving most of the county with very little accumulation. Turns out that "blip" was a mistake, but no one at FCPS was seemingly awake to catch the changes back to the original forecast. Second part is the culture at FCPS - it has become an incredibly hidebound bureaucracy in which individual decision-making is discouraged, and information flows only one way, as input from downstream is ignored (at best). Expect some handwringing and a few mealy mouthed, holier than thou "apologies", but no improvement, as "we're Fairfax and we're the bestest, so there".
I'm quite glad that my kids went thru during FCPS's heyday.
