showmethesnow Posted March 20, 2018 Share Posted March 20, 2018 Any obs from the initial slug of moisture rolling into DC? If we are already seeing sleet pellets mixing in it might be an indication we see an earlier icier solution for the cities. Link to comment Share on other sites More sharing options...

ers-wxman1 Posted March 20, 2018 Share Posted March 20, 2018 06z NAM is a different kind of look. Tucked in low close to the coast idea has backed away, tight gradient north of the M/D line, but our area gets absolutely raked with heavy snow. Bullseye right across from 95 to I-81. Easily double digit snows on the 12km. 500 is closed off, deepening, and crossing a textbook location for us. Link to comment Share on other sites More sharing options...

CAPE Posted March 20, 2018 Share Posted March 20, 2018 1 hour ago, Snowman. said: Ferrier from last nights 00z Run Ferrier current 06z run.. Boom That is a pummeling. A bit more falls beyond that frame for eastern areas. Northern NJ went from about 15" to practically nothing in one run lol. And it looks like Mount Holly weighted heavily the 0z NAMs based off their new expected snowfall map this morning. Something gonna bust, or need adjusting.

showmethesnow Posted March 20, 2018 Share Posted March 20, 2018 The NAM twins suggest that late afternoon, early evening (rush hour) may be a time to watch for a heavier band of precip to pull northward from roughly DC up to the PA line. At this time we see the leftover energy from the closed low to our west that breaks down rotate through our region. May equate to a quick inch or two of snow and/or a heavier burst of sleet depending on location and temps. Link to comment Share on other sites More sharing options...
