Model output discussion - late November
tight isobar replied to Paul's topic in Forecast Model Discussion
Quick answer..NO .. My assumptions/analysis...likely seem that way MOST times.. Hay-ho... That's just how it is . -

And the formats. Are getting fluid...in wanting of gain... As previously suggested!! @cold.. @intresting -

Given the optical momentum/and on short Trop-pv via raw..(such as mentioned)... It's certainly a primmed source for that craved Siberian spill and drop!!. The upper layers are of wait and see after...I'm kicking myself saying this...as the latter is usually the notion...yet were already in front gaining!!! -

And... The notion is there...mixed...but the scatter/compaction.. Certainly going in the wanted direction. -

Watch for the dropline increase on the 6z ensembles.. As mentioned-the Siberian sector pv increase..Will surely be of note... And the ensemble/supports...Will highly likely begin to look stark...in member belly dropping...let's see!!! -

Just a quick one regards..ecm 12z.. Any Greenland push would only act as a 'massive' bonus.. As with a vortex layer format as this...would be a 1 way path... As its a trough drop and load in itself!!= Mass siberian plotting!!! Ignoring the mid/high latitudes blocking... I'd rather this as a guiding tool... Mid December is plyed with promises!!! 1952533423_ECH1-240(18).webp 1952533423_ECH1-240(18).webp -

Nice set for compare @Aberdeen @London ones...the mean getting a grip and is increasingly taking members on a dip!!!..as December walks further. As for cold expansion/inroads.. Middle plot shouting the odds now....ever louder. -

The theme remains...even solidifys 'somewhat. A milder interlude...then at the very least some polar maritime shots...with the notion available..for perhaps more arctic ladden influx... As we get going into December. So all in all the starting gun well and truly fired !!!! !...I'll refrain atm from mention any proposed SSW...as that's a cling..and balance atm...imo.. -

Fools rush in where angels fear to tread comes to mind!!.. The models have big diagnostic problems with vortex...and height placement.. And let's not forget...minor adjustments...are of mass scale.... In our-tiny domain!!! -

Vertical slant...still think those uppers are being underplayed @96+ hrs... And with the dropline around the Russian slot...there's room for argument!!! -

Good stuff. And further highlights the ECM's overall worthyness....as per I may add!! @ for our part @Blessed Weather -

Snow accumulated charts...although take with a pinch buddy...unless your looking 24 hrs within.. Deeper the coulour deeper the depth...with greens lowest ground levels...although again...It's p###ing in the wind with such timeframe! -

The op..becoming more reflective..of the ens... And conversion into colder doesn't take a lot of working out! That's some pv overide being modeled..and with diagnostics in the mix...plenty of exitment looks a whisker away...after our nearly fortified upcoming snap....or perhaps more... -

I think its fare to say any milder air 'shortlived'... And the upcoming colder flow ever more highlighted via ens.. The London ones noting the continental flow!!! ... And after a 'probable' milder interlude...it looks only as if the real headache ...as we stand... Is the direction of cold air transfer ..rather than will it won't it!!! -

An interesting 6z...pumping out.. The slightest alignment of heights on a more westerly stretch will see a continuation of both prolonging cold injection...and likely deeper/colder overheads=850's.. Certainly a seasonal start to the festive month...'nonetheless'!! And some interesting compare-via suites/and particular outs....from here on in! On the above regards....^^ -

Best set thus far...by a mile. And the mid snap is very encouraging..with both expansion....and depth!!!! -

Well steve has a valid point!!= and we find ourselves discussing this year in year out.. The 6z gfs is bottom of the pile...in its sister suites!!=12z =00z =18z..with most time the night run in top pack!!! @00z So lets out this out with the bins!!!.. As again...we've been hear b4...many times b4!!! -

Quite possibly...but it's the interference/diagnosis.. Well before the AZHP push....that could see a very different outcome. Minor energy/dynamical changes...Will be of massive.. major scale prognosis. -

Lots of room for dilution. @upstream. Once the signal gets locked in... Not to mention to now limpet vortex circulation...where any cold weather fan.....wants to see it... Enough already.. the rest is as per an open book....going forward. -

We certainly need an omph.. In Iberian features! Some rapid morphing of systems will definitely aid the eye watering 'mass' e-Euro/Russian hp spread. And tighten the door on a gaining note... The rest out west....is working like clockwork tbh... And the Already talked n-hem- formats are of countinued benefits... -
Saw some of the most accumulated snow I ever have Jan1987= !!!!

Without quoting/commenting via run 2 run.. The gfs this evening getting there...although with the large lobe vortex...any phasing issues around upper Greenland ...should soon become a clearer path through the suites.. And Atlantic ejected waves/systems...Will likely be very short lived features!= leaving open access 'further in that domain. All is good...very good as we stand!!
