By 18 hours it’s already diverged significantly from the “south” camp like the uk and rgem. Someone’s gonna cave very soon because the error is very early on. 8 1 Link to comment Share on other sites More sharing options...

clskinsfan Posted Sunday at 01:28 AM Share Posted Sunday at 01:28 AM Oh yeah. It is coming north. I am comparing to 12Z by the way. Dont know what any other HRRR run has done since then. Link to comment Share on other sites More sharing options...

Weather Will Posted Sunday at 01:30 AM Share Posted Sunday at 01:30 AM WB 0Z HRRR is not going to the Lakes but it is definitely not suppressed. Upper level vortex is north at 11pm Sunday Link to comment Share on other sites More sharing options...
Ravens94 Posted Sunday at 01:30 AM Share Posted Sunday at 01:30 AM It's definitely north this run for sure been going north every run since 6z. Snow touching the lakes. 2 Link to comment Share on other sites More sharing options...
WxUSAF Posted Sunday at 01:31 AM Share Posted Sunday at 01:31 AM Don’t read a ton into it, but KC has had tons of FZRA. Seems like 12z euro had them straddling snow/fzra line now. 3k NAM had sleet. GFS had snow/sleet. 4 1 Link to comment Share on other sites More sharing options...

psuhoffman Posted Sunday at 01:33 AM Share Posted Sunday at 01:33 AM I’m just using the hrrr and rgem here but you can sub the NAMs FV3 and GFS for the hrrr and the uk and somewhat euro (but it’s coming around some) and it’s the same. This is just 18 hours from now… The error is happening right now as the wave amplifies in the plains after ejecting from the Rockies. By 18 hours the camps have diverged and it’s just dominoes falling from there. The Hrrr, FV3, GFS, NAMs are amplifying the wave significantly more in the next 12-18 hours. That’s the difference. 7 1 Link to comment Share on other sites More sharing options...

jayyy Posted Sunday at 01:44 AM Share Posted Sunday at 01:44 AM Still way more to come from coastal. Should be phenomenal Woof! 11.1 in Baltimore proper before the coastal takes shape. That’d be somethin’ alright. Now that PSU has identified what’s causing these model differences, it’ll be interesting to see how the next 12-18 hours play out.

MN Transplant Posted Sunday at 01:44 AM Share Posted Sunday at 01:44 AM This HRRR run is the realistic best case scenario. Wet and cold for most of us with the front side. 9 Link to comment Share on other sites More sharing options...
