Wetbulbs88 Posted January 4, 2025 Share Posted January 4, 2025 16 minutes ago, Newman said: Only looking 36hrs out into the Ohio Valley, we're talking QPF differences of 1-2" in some locations between the HRRR (long-range, I know), the NAM, and the RGEM. The NAM and RGEM being drastically different arises from their depiction of the mid-level vort sliding through, of which the NAM is much more potent and neutrally tilted to allow for a healthy PVA regime, the RGEM is simply flatter and less robust. Looking at H5 trends between the two, it seems they are converging closer together without an all-out "fold" of one model to the other. I suppose we'll see, the Sterling NWS AFD is excellent if you haven't checked it out. Also to note... there are some timing differences to make note of, but not *that* large between these models to expect such huge differences Yeah this is absolutely nuts. This close to gametime, not sure I remember this much divergence. 1 Link to comment Share on other sites More sharing options...
stormtracker Posted January 4, 2025 Author Share Posted January 4, 2025 No huge changes so far...I'm talking surface. Not checking H5 since it lags on SV 1 Link to comment Share on other sites More sharing options...

stormtracker Posted January 4, 2025 Author Share Posted January 4, 2025 It's def a touch colder. SFC and 850 are a little souther...NOT the storm, just those thermals 7 Link to comment Share on other sites More sharing options...

Little less coastal enhancement The vort weakens more than the 12z run which probably explains why its both colder and worse with the coastal.

You can see it on the H5 at H48 on the 18z... on the 12z it is still closed off... but no earth shattering changes... will be interesting to see the 18z Euro and the 0z suite. 1 Link to comment Share on other sites More sharing options...

Thats always a concern when they get the deathband and it dries us out 30 miles south. Just gotta hope it sets up right and we can cash in too.

Terpeast Posted January 4, 2025 Share Posted January 4, 2025 I’m thinking GFS is trying to find a compromise. This might be it 3 Link to comment Share on other sites More sharing options...
nj2va Posted January 4, 2025 Share Posted January 4, 2025 Something to pay attention to within 24 hours on the meso models is the potential for the dual banding to set up…one south and another north like many Mets here have talked about. GFS sort of shows this happening here. 2 Link to comment Share on other sites More sharing options...
jayyy Posted January 4, 2025 Share Posted January 4, 2025 Perhaps a little betwixt the 850 and and 700mb lift?Yep. Makes a lot of sense. Someone’s going to get caught between the dual band structure for a time. Rising and sinking air and such. Hope it’s not Baltimore but it very well could be.

Was expecting maybe a subsidence zone between the two maximas with how strong the h7 lift north and h85 lift south are on some of the CAM’s. Gfs is more like the American mesos and NAM than the south camp. Northern expanse of precip for m/d folks is better this run. Link to comment Share on other sites More sharing options...
