When I think back to 56, it's amazing in that there were no sattelites, they did have radar but it was rudimentary and not widely used outside of hurricanes, NWP was plots and the mathematics were not computer enhanced. I guess that's why the big event on 3/18/56 came with no advanced warning. Some flurries flying by as my mother gave me lunch and I had my eyes glued on the window. I turned on the radio and the forecast was 1-2 inches. After lunch I took my sled to the hilly street with all the other kids in the neighborhood-picture the large number of 8-10 year old boomers. The snow from the event 2 days prior was still quite good for sledding. We didn't notice the fact that snow was increasing and as it was starting to get dark, everyone's mom came out to make us all go home-I guess at that point NWS (then the Weather Bureau) realized it was going to be much bigger than originally expected. As we were reluctantly trudging home with our moms I looked up and realized it was starting to snow pretty hard. The next morning was literally a raging blizzard with snow caked on houses and drifts exceeding 10 feet. One of my all timers for sure.
Now we have so much better technology but it's tough to get it at day 5-6 still.
