Model Output Discussion - Into Winter
Cheshire Freeze replied to MATTWOLVES 3's topic in Forecast Model Discussion
To be honest I was becoming increasingly perplexed by the stubbornness of the NWP in the face of favourable teleconnections. As you say, the gut is rarely wrong . -

GEM looks like the 18z GFS…so clear as mud again this morning! -

There’s still so much play in the pattern. For example, that low could prompt a ridge ahead of it which would promote more of a slower moving N’ly (ala ICON). -

Laughable differences from the 18z to the 0z GFS at 138hrs quite frankly. -

We can’t say that. We can’t say that because at the moment we’re in unusual territory where the strat vortex is being well displaced from it’s usual territory. On top of that we’ve got weather models that can’t even resolve the MJO properly. With the strat so weak, literally one bit of amplification in the right place at the right time could lock us into cold. This isn’t the usual winter scenario where we’ve got a strong strat coupled to the trop with endless strong westerlies above… -

Yeah, it literally shows it in the chart that BA posted. I was just describing the EC46 not giving my own thoughts -

Those charts change so often I really don’t pay much attention to them. Sometimes a dominating pattern isn’t picked up fully until fairly short lead times. The only thing we can say is that a +NAO isn’t heavily favoured into January at this current point in time. -
We can only dream Kev. Even with a decent background set up we can’t seem to shake the Azores HP ridging into Spain and France these days. Almost certainly due to Hadley cell expansion and the changing climate. We’re seeing summers heat up due to it too. The thing that concerns me is that it’s happening so quickly now.

EC looks like GFS at 144 to me 168 chart will reveal more. -

From memory I think Northwich is as far SE thundersnow has got from a NW’ly (from reports on here over the years). -

Thundersnow is one thing I’ve never witnessed. Would love to. -

2004, remember it well. Day started off with horizontal sleet showers and ended with snow piling straight down with little wind. Ended up with 2 inches of snow here. -

Nothing mate. However given the differences between the UKMO and GFS, this is one argument that could develop into something akin to two bald men arguing over a comb. -

Looks fairly good in terms of strat too with that slow moving wave impacting against the HP out east. -

Some decent thicknesses associated with that GFS northerly, temps struggling to around freezing on Christmas Day Entirely possible Mike. Though not looking probable at present for a full GH. I agree though, it’s a bit of an open goal. I’d say more towards the first week of Jan for proper GH chances. -

It’s now a Nartlett North Atlantic Ridge-tlett -

Cheshire Freeze replied to MATTWOLVES 3's topic in Forecast Model Discussion
Yes and notice the North Atlantic ridging appearing…which is completely in line with expectation. Remember a few days ago when I said expect up stream amplification to increase as the NWP gets to grips with the situation? Well that’s what we’re beginning to see. Both the GEM and GFS have it this morning.
