Model output discussion - deep cold inbound?
londonblizzard replied to Paul's topic in Forecast Model Discussion
Movement in the right direction but cold uppers still nowhere to be seen on the GFS 12Z other than Scotland and the far north of England -

Pretty sure the coldest uppers with feb/march 2018 were pushed back until the wednesday, when originally it was going to be the monday? -

If all the models now correct to the GFS it'll obviously be very disappointing, but wow that model will certainly have gone up in cred. It's make or break over the next few runs. -
Model output discussion - is the beast awakening?

No question that the 6z GEFS set is a downgrade compared to the dizzying heights of the 0z and 18z - both in terms of the mean and the number of members going very cold (-13 to -15 850s). Plenty of good cold options in there still though so no reason for despair -

Well very good full ensemble set for London. Still some members going for no cold spell at all. My nerves will be settled once that 850 mean gets into that cluster under -10, and we're arguing about whether it's only going to be -8 or potentially 2018 BFTE levels of -13 to -15. -

Just for fun, and a bit of a side note since BFTE dates were in deep FI at this point, but this is the GEFS ensemble immediately after the SSW just over 2 weeks before the BFTE started. . Only 1 run there (the -15 coldest outlier after 27th feb) resembles what would actually happen. -

My memory of the lead up to the 2018 beast from the east was that the GFS was the latest to latch on to it (with ECM etc showing it first). Almost showing zero cold spell, and then over the course of 2 runs suddenly showing -15 uppers. I want someone to correct me if i'm wrong about this though? Edit: I think what i'm talking about played out on the prior weekend of the 24th feb. Then from this point onwards it was pretty consistent including cross model. -

I count an impressive 19 members which breach the -10 850 mark at some point between the 6th and 8th feb for london. Pretty sure this is the highest yet, despite the mean being comparable to the last several runs. -

Should be a good GEFS set! The mean already dropping to -8 for London -

After being the most outrageously mild ensemble member the entire way through, number 7 takes a 22°C dive to -15 over 2 days on the 11 feb -

Good signs, but really hoping to push this mean down over the coming few days! First week of January had -7 uppers and an east wind in the south east, and it was cloudy with drizzle! -
