psuhoffman Posted January 25, 2019 Share Posted January 25, 2019 9 minutes ago, Ralph Wiggum said: WAR keeps expanding W and subsequently blocking the PV farther W on the gfs The WAR isn’t a cause it’s an effect. Or at most it’s an interrelated piece of the long wave puzzle. The war isn’t causing this to happen. The war is happening because the forcing in the pacific is not favorable to propagate the epo pna ridge eastward into the conus for us. For some reason guidance keeps totally Fng that up at range only to adjust west every time. And so we see each threat adjust west as the whole ridge trough axis shifts west. The causality is the ridge in the pacific is centered off the west coast. That is due to unfavorable forcing near the Maritime Continent. We need the forcing east of there into the western and central pac to drive that ridge into the western US. and that will force the trough into the east and push the war east. You’re right the war there is a problem but you’re looking at the causality backwards. Link to comment Share on other sites More sharing options...

If you look at the MSLP panels it shows an area of elongated LP overhead and to the south of us. As the trough goes negative the LP gains strength to our north. It's all one cohesive (and complicated) piece rotating around. CMC is relatively similar to what the Euro is doing. Link to comment Share on other sites More sharing options...

WxUSAF Posted January 25, 2019 Share Posted January 25, 2019 GFS and GGEM both have some upper-level induced snow in the OH Valley next Wednesday that looks like it tries to create a weak surface low in VA as it moves east. GFS throws out a few snow showers with it, GGEM keeps all the moisture west of the Apps. Another thing worth watching. That would be very dependent on the precise track and strength of vorticity pieces that are rotating around the PV. Link to comment Share on other sites More sharing options...

It’s been trying to do that often the last week but has continually pushed it back or even lost it for many run cycles on the Op and most ensembles. The GFS is likely mishandling the MJO which could be a cause for why it’s continually trying to break the pattern down Link to comment Share on other sites More sharing options...

87storms Posted January 25, 2019 Share Posted January 25, 2019 fairly chaotic looking 12z gfs run. hard to tell exactly what kind of pattern we're heading into. i'm seeing a lot of frontal passages which isn't very inspiring for significant storm threats, but there's also some waves that could trend in our favor.

For now it's a suppressed/squashed wave. Practically every time there has been suppression since mid Dec in the mid range it has backed off as leads shorten. Might be a good thing that guidance is showing a squash job down the line. Much will hinge on the TPV progression which is anything but figured out.

Definitely. It basically shows shotgun solutions and will all depend on timing. Which we are so good at lol Link to comment Share on other sites More sharing options...
