Ralph Wiggum Posted January 19 Share Posted January 19 16 minutes ago, bncho said: The NAM would've been one hell of a run Seems crazy to try and extrapolate the NAM at range, but if we are being honest verbatim, the ull is hugging the Southern Cali coastline crawling along on a trajectory to the baja. It also looks uber wound up. How you can tell that would be a great run, Im not quite sure. Link to comment Share on other sites More sharing options...

But its the Nam at 84 so ain’t like it matters. 2 2 Link to comment Share on other sites More sharing options...
Terpeast Posted January 19 Share Posted January 19 Can’t say I hate being on the north side of the heaviest snows as depicted by the nbm. Still a little worried about suppression, but 12z assuaged that concern just a little bit. 5 Link to comment Share on other sites More sharing options...

Very generally speaking, thunder snow is reserved for storms that deepen rapidly near your latitude (bomb out) or less commonly a vigorous closed upper level low pass creating instability and pockets of big lift. I don't really see either with this event yet so my guess is no. There's a big thermal gradient but otherwise not a bomb scenario or gnarly closed upper level low. 2 Link to comment Share on other sites More sharing options...

How you can tell that would be a great run, Im not quite sure. 12Km NAM posts should be hidden in a serious storm threat thread at this range, or any range come to think of it. It is about to be retired, and should already be. The Panasonic(which doesnt really exist) is better. 2 Link to comment Share on other sites More sharing options...

Steve25 Posted January 19 Share Posted January 19 Made the mistake of getting on Twitter and seeing nothing but Webb and a bunch of other southern weather personalities going on and on about how the AI models have no grasp on how strong that High is going to be and once they pick up on it, this is all coming south. Someone intelligent in here please tell me they’re being somewhat biased lol Link to comment Share on other sites More sharing options...

It’s about if that energy off the west coast can push east enough to get under the flow in time to spark this thing up. 1 1 Link to comment Share on other sites More sharing options...

Someone intelligent in here please tell me they’re being somewhat biased lol It’s not just the strength of the high, it’s the confluence area that sets up between the TPV lobe off Nova Scotia and the impending s/w digging out of Central Canada. The stronger the high, the drier the airmass and colder temps at latitude, but if you have an ejecting piece that phases and pumps the heights out in front a bit, you’ll get precip, but could be more mix. My main concern with this setup is and will always be suppression. It’s a tight rope walk, but a weaker confluent axis tends to verify a little closer in reality, but we’ll see. 4 Link to comment Share on other sites More sharing options...
