DCA is a terrible place to judge your winter snowfall forecast. I would use IAD too. The blizzard of 2016..DCA had pedestrian results...and i had like 38 inches
i havent seen once this winter where we take a good run and build on it lol...we have never even taken one step forward to have a chance to go 2 steps back
i knew this would happen. we would get all these NW storms and a southern slider. IN the worst winter ever before this one(01-02) there was southern slider that gave Norfolk 14 inches and we got clouds
having the NAM keep showing this keeps hope alive....and the hope the euro responds..but as we all know...if it was us...the 00z NAM would takee us from 6-12 to a dusting in one run
how long is that 50/50 going to hold though without any blocking? it seems like more of the SOS
edit--there looks like there is some ridging under greenland that may allow it to hold?
