In December,, 1960, my father scored Giants tickets against the expansion Cowboys who were 0-7 up to that point. They managed to tie the Giants that nearly 70 degree day 12/4/60. As that week progressed, temperatures stepped down to normal but the following Saturday was still 40s by day dropping sub freezing Saturday night. I wake up Sunday to what was then "provisional heavy snow warning" which is akin to WS Watch today. My mother made me sweep the oak leaves out of the garage and I happily did it as we faced north and the stinging wind carrying termperatures in the low 20s was in my face. Cirrus was spreading across the sky which by mid day was starting to blot out the sun. I turn on the Giants/Washington game at DC and the announcers start by saying we're having a blizzard in Washington! YA Tittle hits Del Shofner who scored the TD and ended in a snowbank. by 3PM it begins snowing lightly with the temperature near 20. It was one of those deals where it took forever to develop but unbeknownst to me the secondary was bombing off Hatteras and slowing down. We had an inch from 3-9PM. Then things began ramping up and at bedtime, with my bedroom facing the side of the house, I often opened the window and stuck my head out and craned my neck to check out the street light across the street-and low and behold it was starting to snow hard. I woke up at 5 AM to a raging blizzard-one of the all timers given the wind gusts exceeding 50 MPH at times, temperature of 9F, and heavy snow. Looking back and reflecting on Tip's post above, I am thinking that's how you do a December blizzard. We ended up with 18-24 throughout much of the area. It was one of 3 biggies to hit DC-New England during that glorious winter of 1960-61.
