bncho Posted January 23 Share Posted January 23 I think HRRR might lose thermals soon but if it holds out until the end of its run then DC gets 10" Link to comment Share on other sites More sharing options...

Eskimo Joe Posted January 23 Share Posted January 23 Yea the 18z HRRR is definitely colder and wetter. More snow for I-95 and points north and west. More sleet than ZR for southern MD too. 7 Link to comment Share on other sites More sharing options...
bncho Posted January 23 Share Posted January 23 HRRR's gonna be ~10" in DC. They flip to sleet/rimed snow at 11AM. Link to comment Share on other sites More sharing options...

Stormchaserchuck1 Posted January 23 Share Posted January 23 18z Hrr again looks like all snow Baltimore-north. Might stay that way for the duration as it looks like it transfers the coastal fast/south again. The RAP and Hrr specialize as short term models, better accuracy within 24-36 hours, but it looks like 12"+ Baltimore north. 6 Link to comment Share on other sites More sharing options...
yoda Posted January 23 Share Posted January 23 Yes I know its the 18z HRRR at the end of its run, but note 700-800mb. Doesn't go positive aka above 0c. This is the sounding at DCA. Yes, its probably rimed snow... but i don't think this shows a pure sleet profile 1 Link to comment Share on other sites More sharing options...
Terpeast Posted January 23 Share Posted January 23 Love the HRRR run. Probably out of its range, but see its trying to start a coastal. 4 Link to comment Share on other sites More sharing options...

MN Transplant Posted January 23 Share Posted January 23 Lord help us all for looking at the HRRR at range, but it is a good 0.70" QPF before the flip in DC. Nice run. 12 4 Link to comment Share on other sites More sharing options...

NorthArlington101 Posted January 23 Share Posted January 23 Could be WxBell just being funky, but it tries to accumulate some snow after the flip to sleet while also accumulating sleet on the separate sleet panels. True wintry mix? Can it try and split 50/50 what falls? No idea. Just now, yoda said: Yes I know its the 18z HRRR at the end of its run, but note 700-800mb. Doesn't go positive aka above 0c.

It's not on an island. Most of the 12z suite ticked colder throughout the column. 4 Link to comment Share on other sites More sharing options...
baltosquid Posted January 23 Share Posted January 23 18z RRFS continuing to bring the plains HP further southeast at hr15. Need as much push as we can get to prevent the primary from climbing. 2 Link to comment Share on other sites More sharing options...
Terpeast Posted January 23 Share Posted January 23 IAD is close to flipping at 48 (18z) on HRRR. This is probably the time it flips. 2 Link to comment Share on other sites More sharing options...
baltosquid Posted January 23 Share Posted January 23 18z NAM also at hr15 is bringing the HP further into the plains, and a bit stronger. Heights pressing a bit more. Keep the trend going... 2 1 Link to comment Share on other sites More sharing options...
Terpeast Posted January 23 Share Posted January 23 DGZ looks fantastic on the HRRR right before the flip, too. If this holds, oh my... 6 1 Link to comment Share on other sites More sharing options...

Many/most runs today have really heavy snow leading into the flip. Like that 14-17z period probably 1-2”/hr 6 Link to comment Share on other sites More sharing options...

I see that, we’d have some good growth, dendrite central. Can still see the NW crew pulling off 13-15:1 ratios. Link to comment Share on other sites More sharing options...

Stays really cold out this way though. Nice to see the models starting to get an idea of the amount of cold coming. 1 Link to comment Share on other sites More sharing options...
WEATHER53 Posted January 23 Share Posted January 23 I don’t see gaps or weakness in the highs from Chicago to Long Island Wall to wall 1035+. It will be a new and learning experience if a modest low can dislodge that 2 Link to comment Share on other sites More sharing options...
