I am a weather observer at Dulles International Airport. I worked the storm last week from 3 pm Friday to about 9:30 am Saturday. I measured snowfall every hour, and kept a running total of hourly snow fall, snowfall from that event and total snow on the ground (from previous snowfalls). We received nowhere near 32.4 inches. Indeed, when I left Sat morning, we had (as I best recall, worked a lot of hours this weekend) about 19 inches total, and roughly 17 of that was new snowfall. When I returned to work at 2130 Sat night, we had 22-23 total, and the snow had stopped falling around 5 pm.
Office scuttlebutt has it that NWS at Sterling only actually measure 24-26. Management there decided to invent about 8 inches of snow out of wholecloth, apparently.
I only mention this because they are now in CYA mode and trying to blame the observers at Dulles and Baltimore (and maybe Reagan, not sure) for not knowing how to measure snow. The simple fact is that the 32.4 that they sent to the news is an anomaly when compared to surrounding areas. If one was doing a statistical analysis, they would throw out that 32.4 immediately for being ridiculous.
I fully admit I'm not a genius, but I am capable of sticking a ruler in the snow and seeing how far the snow comes said ruler.
my home is near Rt 7 and Reston Road. I measured 33 inches of snow in 3 different locations in my yard on Sunday morning. All three measurements were in areas protected from the wind.
I don't think this is so far fetched.
