Amped Posted January 3 Share Posted January 3 Gfs caved in with the jet in the pac nw. It's flatter at hr 27 compared to 12z. Should mean less amplification downstream. Link to comment Share on other sites More sharing options...

DDweatherman Posted January 3 Share Posted January 3 Want to see the gfs continue a great UL pass and coastal enhancement regardless of track for the WAA slug. Could save us northern folk if we do get screwed. High ratio backside stuff has been the savior before. Link to comment Share on other sites More sharing options...

nj2va Posted January 3 Share Posted January 3 1 minute ago, stormtracker said: It's not close on my maps Yeah 9z definitely still snow. This is 12z. Pivotal says sleet on the maps but snow on the sounding. Heavier rates would probably keep it snow but its super close. Splitting hairs with thermals this ‘far’ out on the GFS though.
