Benjamn3 Posted Saturday at 05:01 PM Share Posted Saturday at 05:01 PM By this evening when all the models have a good sampling of data I’d say things will be more inline. Which way things go is up in the air. Just pour a drink or spark a bowl. 2 2 Link to comment Share on other sites More sharing options...

hstorm Posted Saturday at 05:07 PM Share Posted Saturday at 05:07 PM For anyone who hasn't been following closely, UKMET has been the most southern model for a few runs. 12z appears to be marginally further south than 6z, but no drastic shift.

nj2va Posted Saturday at 05:08 PM Share Posted Saturday at 05:08 PM UK and GFS comparison at H51 below. Our SW is a bit further south on the UK but look up north. UK has a closed low vs open wave on the GFS. I think that’s impacting it but I’m stoopid so what do I know. 5 Link to comment Share on other sites More sharing options...

So the GFS is trying to drive the surface low north. The UK is not. Crazy the difference this close to the event. 1 1 Link to comment Share on other sites More sharing options...

The s/w position at h51 isn’t all that different and really nor are the heights to cause as much ground truth difference. But downstream from this is where the effects are magnified and the big divergence is. 1 Link to comment Share on other sites More sharing options...

But I’d take it looking exactly like 6z if we’re being honest. That alone is enough to think the UK is on something. Link to comment Share on other sites More sharing options...
csnavywx Posted Saturday at 05:16 PM Share Posted Saturday at 05:16 PM 1 hour ago, stormtracker said: WB has it as sleet or something according to Will's map. You have the sounding? Sometimes WB paints sleet in snow/close snow situations ETA: Nevermind. Saw you edited and said you checked the sounding Needs to be >10 J/kg or the hydrometeors won't melt. Verbatim it's still snow. The real issue is the dry slot impinging aloft around this time, which starts removing most of the ice crystals. Snow growth gets inefficient or flips to snow grains and/or freezing drizzle until around 5pm, when the IC layer is restored as the main vort maxes passes south. 7 Link to comment Share on other sites More sharing options...

That appears to be a key difference at 500mb. 1 Link to comment Share on other sites More sharing options...

That appears to be a key difference at 500mb. It's also open at H5 vs. GFS which keeps it closed for a while longer. Makes a difference to the WCB. 4 Link to comment Share on other sites More sharing options...
WEATHER53 Posted Saturday at 05:21 PM Share Posted Saturday at 05:21 PM I would not worry about coastal snow being s-se of us. In a transfer it’s almost always missing to ne that’s the problem. The overrunning does not look suppressed, The high is building in slowly and does not appear to be a 30.50 suppressive monster Link to comment Share on other sites More sharing options...
