Sunday plastered the Shenandoah Valley with a very unusual snow-event. Wide variations in accumulated snowfall occurred within short distances. Similar conditions occurred in W.Va and Md./ Del.
The NAM Nest 700 mb. chart illustrated a sharp trough with extreme lift turbulence over Augusta County Sunday afternoon. I received a strong inch in a heavy band while a friend a few miles away had bare ground. Luray reported a half inch while a friend a few miles away up on Tanners Ridge at 2700 ft. near Big Meadows reported at least 6 inches with high winds. When I was preparing my Newsletter early Monday I looked at local snow totals. Stuarts Draft has 3 reporting stations on the west side within a couple miles apart. One station reported 0, another reported 1 inch while #3 reported 4.5 inches! I reported 2 inches for Stuarts Draft. In question, Wintergreen reported 3 inches at 7:30 am Sunday, 6 inches at 3 pm Sunday and 15 inches at 7:30 am Monday. Is this 100% accurate?? I don't know because I didn't take the measurements. If we deny snowfall reported by the NWS because we disagree , we are hopeless. I am currently working on the last 125 years of snowfall for the Valley. I am relying on Staunton Records, Dale Enterprise Records and 60 years of personal records with occasional cross-references. Many of the people who made those records have been dead for more than 50 years. How did they measure snow? Did they use snowboards? If so, how often did they clean the snowboards?
West Virginia also had as you say, 'ridiculous" reports for Sunday. Holly River State Park reported 22.5 inches with a picture of measurement on social media. 10 - 15 miles away, Webster Springs only reported 6 inches.
Md/Del. also had "ridiculous" reports with 4 - 20 inches within 10-15 miles of each other at midday Monday.
I'm always interested in snowfall reports but I am keenly aware that we don't live in a perfect world regarding measuring/reporting snowfall or any other factors in our lives.
