NorthArlington101 Posted January 21 Share Posted January 21 One thing worth noting on the NAM, perhaps, is that it seems very skeptical of freezing rain as the dominant non-snow Ptype. Lot of sleet, even way down south. 4 Link to comment Share on other sites More sharing options...

clskinsfan Posted January 21 Share Posted January 21 CAD at onset is really tasty on the NAM though. With the cold air still pouring down east of the mountains. A lot of cold air to scour out before any flip. 2 Link to comment Share on other sites More sharing options...

Lot of sleet, even way down south. I think that makes a lot of sense with how deep this arctic airmass is. These NAM runs are going to be showing like 3-4” of sleet I’d bet for the mid-south in the next couple days. Link to comment Share on other sites More sharing options...
Weather Will Posted January 21 Share Posted January 21 Great NAM is showing a strong storm and strong high rather than strung out crap at 84.....otherwise pretty worthless to interpret. 1 Link to comment Share on other sites More sharing options...

IUsedToHateCold Posted January 21 Share Posted January 21 It's the NAM outside of it's reliable range (if that is even a thing), right? I can't be worried with a 1042 High Pressure sitting right to the north. Next. Link to comment Share on other sites More sharing options...

stormtracker Posted January 21 Author Share Posted January 21 I'll wait for the pros to chime in (and yes we know it's the NAM but we need entertainment until the real models), but the NAM honestly doesn't look that bad. Cold looks impressive enough maybe to offset the amping a little. Also, keep in mind, this could be 100% weenie coping at the moment too. Probably more that. 4 Link to comment Share on other sites More sharing options...

I think there is almost no question we at least get a 5-10" thump. The question of the day, which is hopefully resolved by the end of the day so we can set expectations, is whether those of us in the typically sleet-vulnerable areas need to be bracing for snow or sleet after that flip. Didn't look like an issue yesterday so I think folks are appropriately riled up. 3 2 Link to comment Share on other sites More sharing options...

I tried it and it gave me a well-worded laid out 12 hr forecast following the 84hr map of the 12z nam. Basically said it was redeveloping off the coast and on its way to clobber upstate NY and New England. Sleet storm for DCA/BWI/PHL. Clearly Gemini cant extrapolate as favorably as us weenies do. 1 Link to comment Share on other sites More sharing options...

StormyClearweather Posted January 21 Share Posted January 21 In the "old days," the NAM was the best at CAD setups, especially the 3K when it gets into range, and models (especially globals) scoured it out too quickly. As Randy said, might be weenie coping, but I hope that's a trend we see continue as we get closer. 3 Link to comment Share on other sites More sharing options...

Extrapolated NAM would be an overturned semi hauling Grape Nutz in my yard lol. Had a feeling yesterday morning that in the end a sleet bomb would be more likely than a top 10 snow event. Odds increasing every suite lol. 2 2 1 Link to comment Share on other sites More sharing options...

Ralph Wiggum Posted January 21 Share Posted January 21 Rgem has more separation out west wrt the baja ull and the ns trying to phase in. A little slower to move out too? May be a less amped outcome. 2 Link to comment Share on other sites More sharing options...

Phase looks maybe a tad more disjointed, Baja low not getting pulled up in front of the NS protrusion to the NW as much? Overall not a huge change but not gonna get amped to death past 84 I think… Link to comment Share on other sites More sharing options...
