That GFS is a minor tweak away from being epic for everyone.

Messy on the 18z GFS op run in the medium to longer term http://www.wetterzentrale.de/maps/GFSOPEU18_186_1.png 


That could go either way and should really be viewed in the context of the ensemble data later.

In 1891, though, I don't think the milder air ever made landfall in the UK.

GFS18z brings a mix of rain, sleet and snow next Friday and Saturday. Not a big fan of this evolution at all.

March 1891. A tweak here and there and this could be a repeat.

Truly bizarre synoptics by 222 hours with a NE to SW flow across the entire Atlantic. I think GFS is losing the plot.

GFS has been worryingly consistent though, three runs in a row it has done this with the low pressure. ECM has also been pretty solid too.

This is one situation when a "halfway house" would be spot on!

UKMO 168 probably a little closer to GFS but hard to say given the orientation of that chart.

The 12z Op was far more progressive with the mild incursion that almost all other perturbations, including the control.  Interesting... but even it itndoes gonthe way of the 18z Op, it will have been a special spell, albeit short.

There's always some sort of hurdle to get over when we look forward to cold spells. Usually we fall flat on our faces at some point, or at the very least we twist an ankle and limp over the finish line. One final hurdle is this low on Friday - let's hope GFS is out on its own and backtracks in the days to come.

FWIW my automated forecast on my phone has just flipped colder for the weekend. Now shows snow on Friday Saturday and Sunday!

Brian - no idea if it's MOGREPS control or not, I'm just calling it what everyone else calls it!

Looks like a bit of a shift towards the op run solution in the GEFS. Mean is two degrees higher by T156 in London, more members bringing in milder air.

However, nailing the Northerly extent of the advancing low which is almost a week away, must be subject significant error. 


I'd take a punt at GFS being right in terms of the general pattern, but there's no need to worry too much at this stage about the detail. At least 4 to 5 days of deep cold and snow looks pretty much nailed on now.

ICON 18z UK snow depths at t+120:

Here's the cumulative precipitation chart. Given the wind direction and strength that just doesn't look right.

Interesting how both Wednesday and Thursday are showing maxes of -2c in many areas yet the BBC fail to come up with any warnings and over cook temps and show +2c But anyway back on topic.,


Looking unusually cold for mid afternoon this Wednesday and Thursday: I wonder what the windchill would make it feel like -10c? seeing as the BBC can't talk about this?

Control has the mother of all snowstorms at t180. Takes the low even further north than the op but it's colder, too.
