1/10 looks CAD-ish to me. Doubt interior would get wiped…could even be a net gain if you get a decent front-ender. It’s still 10 days so not sure the obsession with it anyway.
Aside from the storm threats over the next 10 days, the LR improved overnight…that NAO blocking is still showing but the N PAC looks a lot better. Poleward EPO ridging showing up post-10th.
Pretty much all of the I-35 corridor cities in TX will get totality. San Antonio/Austin/Waco/Dallas. Waco is right in the middle though so they’ll get it the longest.
Yeah some of those prob had some northern stream insert at some point before turning the corner. That event doesn’t look like a classic phase since there’s a trough out west…but getting a bit of northern stream energy into it prior to it turning north would help out.
The two systems almost have opposite problems.
1/5 we’re needing a bit more southern stream phasing (ala GGEM) and for 1/7 we need more northern stream injection.
That’s what I’d be looking for on each model cycle.
I honestly have no idea what you’re talking about. The 1/7 setup has a high to the north. It’s not advecting in PAC air as it approaches. It would be drawing down air from that high.
I actually agree that 1/7 is still a longshot but I won’t confidently dismiss as easily as you because it’s not a prerequisite to have a ridge out west to get those to gain latitude. You’d just want to see that southern stream a little deeper…incorporate a bit more N stream energy before it tries to turn the corner. We’ve seen several big southern stream storms in the past with a trough out west.
EPS is really trying to build the -NAO mid-month. Like retrograde that North Atlantic ridge back into Greenland and Baffin/Davis Strait. That would keep things interesting despite a meh N PAC
You need a bit more northern stream insert on the Euro for 1/7 or you need confluence to lift out a little faster. Plenty of time on that one, but that’s what you’ll want to look for in the coming days.
GFS suite is producing more northern stream light snow than before. Southern stream doesn’t really phase in well like on GGEM or ICON…but that deeper northern stream does give us a “consolation prize”.
It’s extremely hard to put a percentage of attribution on a thing like snowfall over a short 5 year period. Snowfall is one of the highest variance weather outcomes we have. Some of the warmth is definitely connected to CC but not all of it.
