MN Transplant Posted February 9, 2021 Author Share Posted February 9, 2021 The NAM wants to sneak a warm layer at ~800mb to DC. Not sure that it is realistic based on all the other modeling. 1 1 Link to comment Share on other sites More sharing options...

GFS/Euro definitely haven;'t been following the NAM the last few cycles. They've gone the other way Perhaps...and I'm always up for my intuitions being proven dumb. I'm curious to see what happens with the 12z globals and how they do or don't line up with 12z NAM shifts. Link to comment Share on other sites More sharing options...

LP08 Posted February 9, 2021 Share Posted February 9, 2021 Maybe its just me, but the second wave looks to be benefiting from a little more space from the first impulse. Looks impressive through 57. Link to comment Share on other sites More sharing options...

And now has a break in the precip. I hope nobody is worried that this is the final, locked in solution. Even at this "late" hour. Link to comment Share on other sites More sharing options...

ovechkin Posted February 9, 2021 Share Posted February 9, 2021 The only “worry” from this run is marginal temps. We simply don’t do marginal well anymore. Hopefully it’s not correct since no support from other models temp wise. 1 Link to comment Share on other sites More sharing options...
LP08 Posted February 9, 2021 Share Posted February 9, 2021 Definitely a bump north with the second wave, Ezf to Richmond crushed. Link to comment Share on other sites More sharing options...

Yeah, at 63, it got sheared down a little north of I-70. Still wouldn't worry up there. I'd rather be up there than here, I don't care what the NAM shows. 1 Link to comment Share on other sites More sharing options...
baltosquid Posted February 9, 2021 Share Posted February 9, 2021 NAM 12k is a ways north and stronger with the second wave compared to the last run. Still fringes Baltimore and northward but getting closer. 2 Link to comment Share on other sites More sharing options...

Edit: Let's see if my "theory" about the NAM "leading the way" in the quite holds true. Precip increased on the northern edge for this run.

jaydreb Posted February 9, 2021 Share Posted February 9, 2021 The second wave seems to be the main show. Let’s hope that hits most of us squarely. Link to comment Share on other sites More sharing options...
LP08 Posted February 9, 2021 Share Posted February 9, 2021 I tried my best to break out both waves, but I am missing some around the edges only having a 12hr period. 1 Link to comment Share on other sites More sharing options...

clskinsfan Posted February 9, 2021 Share Posted February 9, 2021 The NAM definitely ticked north with the second wave. Best run from that model for my area yet. Good trends so far at 12z IMO. Link to comment Share on other sites More sharing options...
baltosquid Posted February 9, 2021 Share Posted February 9, 2021 Would have liked to see a few more frames of the 3km, definitely a big north bump on wave 2, a little more so than the 12km. 3 Link to comment Share on other sites More sharing options...
T. August Posted February 9, 2021 Share Posted February 9, 2021 3k pretty far north with the 2nd round. Gets precip to Baltimore. Albeit light. Link to comment Share on other sites More sharing options...

Kmlwx Posted February 9, 2021 Share Posted February 9, 2021 This is a cut and dry question - and the reason why we try to lean away from having people ask "when will watches be issued" It's cut and dry in the watch definition. https://www.weather.gov/lwx/WarningsDefined - that is an EXCELLENT resource page for newer members. Winter Storm Watch A Winter Storm Watch is issued when there is the potential for significant and hazardous winter weather within 48 hours. It does not mean that significant and hazardous winter weather will occur...it only means it is possible. Significant and hazardous winter weather is defined as a combination of: 1) 5 inches or more of snow/sleet within a 12-hour period or 7 inches or more of snow/sleet within a 24-hour period AND/OR 2) Enough ice accumulation to cause damage to trees or powerlines. AND/OR 3) a life threatening or damaging combination of snow and/or ice accumulation with wind. The snow/sleet criteria for a Winter Storm Watch for the five westernmost counties (Allegany, Mineral, Grant, Pendleton, and Highland) is higher (6 inches or more within a 12-hour period; 8 inches or more within a 24-hour period) 4 4 Link to comment Share on other sites More sharing options...
