    The December 2009 blizzard was special and so was the 12 day span from January 30 2010 to February 10th 2010.....probably never again will we hit 4 straight overperformers with snow upon snow. Although, January and February 1996 was special in southern MD. We were hit good from the blizzard but nowhere near the jackpot, however southern MD hit several overperformers afterwards for 10 plus inches all snow on snow.

    For straight up cold the Winter of 1976 and 77 was hands down the winner, first time ive seen ice fog. 1994 as cold as it was and so many ice events, comes a distant 2nd. 

     

    Surprise snowfalls, PD1(Feb 79) was suppose to be an 8 inch snowfall and was triple or more than that by dawn with huge wind and rates here in southern MD......the number 1 snowfall ever down here. Visibility was as low as Ive seen for any local snow event ever. Hands down the best event for anyone who lived through it.

    January 25th 2000 was another gigantic suprise snowfall that jackpots the eastern suburbs, just as Veterans Day 1987 was another DC and immediate eastern and southern suburbs jackpot on the thundersnows that day.  

    As the Redskins were winning a Super Bowl  After the Redskins exciting postseason fell just short of the Super Bowl, we had a pair of double digit snowfalls early in 1987 that paralyzed the region and southern MD was the jackpot. Fun memories and we are once again due for some large events.

    Superstorm 1993 was the most hyped storm, and it lived up to it's billing. We did not jackpot locally, however that was a rare, dangerous Winter/Spring event. I was in Richmond VA during this storm amd witnessed the low passing directly overhead. 

    Richmond received 4 to 6 inches of snow overnight then changed over to windswept rain and temperatures in the 40s. As the low passed over the rain slackened and wind went calm as the sky brightened. 90 minutes later the roads were flash frozen as temperatures plunged back to the upper 10s with heavy snow and winds. One rare storm that delivered a major punch on the backside.

    Dulles was reporting 65 dew point, Andrews AFB was 67, College Park AIrport 67 and Warrenton Airport 60 as of the past 30 to 40 minutes on GREarth. There are plenty of other locations reporting 69 to 73 dew points. When sun broke through full, I went out and read 86 degrees with a 66 dew point at Noon. Was using a Kestrel 4500. Hope as many of us can cash in on meaningful rains today.
