87storms Posted January 11, 2019 Share Posted January 11, 2019 nam looks like a hold so far. i don't see much change. maybe a bit better than 12z for areas south and east. Link to comment Share on other sites More sharing options...

Bob Chill Posted January 11, 2019 Share Posted January 11, 2019 18z nam is a nice run but I'm always so skeptical of the model that I generally only believe it when other guidance looks the same. Either way it's a solid run with DCA hitting warning criteria. Link to comment Share on other sites More sharing options...

MGorse Posted January 11, 2019 Share Posted January 11, 2019 18 minutes ago, HighStakes said: Since LWX changed the format in the text when they issue watches, warnings, etc. they never include temperatures during event. You would think the general public might find this helpful. Kinda mind boggling The change was nationally. Temperature info is in the actual forecasts.

PivotPoint Posted January 11, 2019 Share Posted January 11, 2019 Big run on th nam and still going. .5-.6 DCA and not done. Deform shield more consolidated. This is NAM’s wheel house so hard to totally discount. Still skeptical but as depicted looks realistic given current trend. This might be happening Link to comment Share on other sites More sharing options...
