Yeah the 12z Euro OP was a little different due to some modeled changes. Mainly a stronger initial system around like the 14th pulling down colder air. The issue is that the flow is just too fast and nothing is amplifying.
So instead of getting a low forming, you just get positive trough coming out of the 4 corners region.
The GFS has been running too cold with temps lately. So I wouldn't be shocked to see a northward movement in the snowfall chances with the system around the 15th-17th.
CANADA EH?
Yeah, there's split flow, and models will have trouble resolving it and will probably change a lot. It looks like it will at least be more exciting with colder air around.
I'll take an order of #21 or #22 please.
I did that a year or two ago, looked at the Euro ensemble for trends, and it changes too much from run to run to make a difference. Saw like an 80% chance of snow dwindle to nothing in one run, lol
Thanksgiving looks a bit cold and rainy(mix/snow in some places early)
Looks like we'll have this initial system on Tues.
Then mix/snow to rain on Thanksgiving:
Followed by rain on Fri:
And maybe some rain/snow showers on Saturday into early Sunday:
Looks active at least......
Models are changing a lot from run to run in the extended, but it does appear that a big system will be possible sometime around Thanksgiving. Severe weather probably out ahead of it and maybe a blizzard behind it.
Yeah I saw that next weekendish. Just a very marginal setup where a lot of things can and probably will go wrong or trend in the wrong direction. We'll see though.
I guess the EPS (Euro) has a lack of blocking, which results in warmer temps. This was last night. FWIW, the Canadian is on the GFS side as well. Plus tropical forcing should be more towards the GFS as well. The Euro or GFS is gonna bust.
Yeah, we're going to warm up as the flow changes. Pacific air will be flooding in and things are going to be kind of boring for a week or two at least.
Someone posted the Euro weeklies here and it's kind of 50/50 unsure.
But this looks somewhat better:
