Yeah, I am not sure what protocol they follow or how well they follow it.
10" sounds safe. I think another poster on here from somewhere near Denton measured 10 as well.
All those emergency managers seem to be slightly slant sticking...COCORAHS guy in Easton is obviously not a weenie
In all honesty the mesonet stations probably give a good approximation
Yeah talked with my DE coworkers 12 to 16" trees down everywhere, same in Salisbury.
Yeah, this is a pretty typical result for the Eastern Shore. In my decade plus here my region usually underperforms for the reasons you mentioned and I reset my expectations. I was guessing Greenwood DE to coast would maximize and Easton would be 5 to 8". If the daytime accumulated better would have easily been closer to 8". Overall pretty good forecast by NWS.
The Eastern shore had a steep gradient. My forecast was 10 to 15" ended up with 5.5". Just to my east CAPE land down to Denton had 8 to 10" then most of Delaware to the beaches had 12 to 20". A lot of trees down in DE and Lowe shore of MD.
