balltermen Posted January 24 Share Posted January 24 Wow. Flip isn't until 18-19z. DC gets 12" of snow and then maybe 1" sleet. Is this even possible. Not biting. ETA - I was on wrong panel. flip at 16z-ish. Link to comment Share on other sites More sharing options...

Scarlet Pimpernel Posted January 24 Share Posted January 24 3 minutes ago, NorthArlington101 said: Using the 6" line for reference, it looks like that now bows out more to the southeast, which is nice to see. Can't recall if that's similar to 18Z and earlier but still. Link to comment Share on other sites More sharing options...
nj2va Posted January 24 Share Posted January 24 Looking at soundings, DC flips around 16 or 17z Sunday on the GFS, which is pretty close to the Euro. GFS QPF is ~0.8” so a really nice thump. 4 Link to comment Share on other sites More sharing options...

Not biting. The key is that it drops ~0.75-1.00" QPF by that point, huge thump right there. Whereas the NAM was a lot drier for the snow part (and of course it had an earlier flip as well). 1 Link to comment Share on other sites More sharing options...
balltermen Posted January 24 Share Posted January 24 23 minutes ago, yoda said: Looks like .75" QPF before flip DC metro i see around 0.85" through 18z which is a foot at 14:1 ratios. Not predicting this but holding on to snow for an extra 3 hours could mean another 4-5". The difference between a 9am and 2pm flip is significant as to totals and impact. ETA - i was on wrong panel. flip at 16z. 8-10" snow for DC. 2 Link to comment Share on other sites More sharing options...

IUsedToHateCold Posted January 24 Share Posted January 24 The model guidance is pretty close at this point, with some variations. NAM is a major outlier with a much more amped/warm system. Needs to be watched tomorrow to see if it's sniffing something real. I think 10-12 for DC (snow and sleet) is still what I think will happen. Tomorrow we'll be watching the energy cross the country, so it will be fun and interesting to see what happens. Link to comment Share on other sites More sharing options...
