A severe storm within 120hrs fetch the camera Its usual antics are showing full blown monsters out in the 'cosmos' so do take note here.. there would be plenty of media coverage since for once the storm is not impacting Scotland! Course it can downgrade more likely but time is closing in & potential for it to upgrade further / or strongest winds to move S affecting densely populated regions which would not be very pretty. Londoners teeth will be clattering anything over 30mph is quite infrequent I tell you.

Oh Lord don't be saying that underserved pressure! I disclosed the possibilities that still stands also evident on GFS 18z some leading edge snaw.

Ah you will be...200m not high enough how could you say such....On a side note 50m seems quite steep for me being 6m ASL wanna swap?

Both GFS & UKMO develop a shortwave out in mid Atlantic GFS 'zipping' it through the English Channel and I suspect the UKMO would do the same implying a snow risk for the S.

Apologies I get frustrated. To quote from @fergieweather: Yes, it's been consistently modelled: this occlusion engages colder (<400 m WBFL) air as it trundles south tonight; some snow thus expected down to about 200 m as it runs across uplands of N England and beyond to N Wales/N Midlands. From 200-300m, perhaps a couple of cm of snow in places; but several cm likely up above 400 m modelled by UKV, such as across the Peak District. It is strange he has not commented on London, SE & EA where actually it is not as marginal...I suppose it is whether the precip survives the trundle S and the time of day. Well the precip looks to make its way towards our region ideally before 9am as higher WBFL move in from the west, WBFL- the height above sea level where the temperature is at freezing point modelled by GFS is <100m WBFL at 6am for your part of SE Essex.... you would have no trouble seeing snow with that. I definitely think the hills might get a light covering the downs ect.

See the above if you have eyes @Surrey well I don't really care, it would just be nice to see in this rather void winter. proof is in the pudding Elvis.. Could end up a bust for all I know. However the parameters are there for snow to fall to low levels especially London/North Kent northwards. As illustrated by that WBFL chart snowray provided.

Surrey no one is interested in tonight's rain do you have an agenda? it is what comes towards our region approx 6-10am Wednesday morning. Lovely day Here is Stave Hill with sun gradually setting in the background & some more pics:

The euro4 has not bad parameters for 9am. Dew points - check Uppers - check (don't expect powder snow ) Temperature 2m - check

You're not showing the appropriate charts see the bulge near western isles this is bringing precip southwards down the country and indeed there could be wintriness early in the day.

Undertones of excitement & adrenaline?

The worst is yet to come for some of you nasty winds currently affecting western Isles where the gradient is quite sharp transferring eastwards through the night the highland capital right in the path I'd expect the peak around 3am, for Inverness. As Henry pulls away he does leave a burn, for Aberdeenshire, Moray...peak circa 6am. A narrow path seeing sustained winds in low to mid 60's only 10mph or so away from a category 1 hurricane strength for Rosehearty for instance - gusts in the 80's this is a nasty proper storm.

Very nice picture of Nacreous clouds spotted in Norfolk this evening thanks to Storm Henry.

Spot the difference between 12Z & 18Z. The white flag is still in the vault for the time being

Slower evolution here but good to see some consistency the ridge also less west based.

I do not have much interest whether it will snow on northern hills - however this chart looks decent courtesy of Michael Ventrice cyclonic yes - but it may become cold enough for snow (not just for the usual culprits) the AO & NAO going negative!! hooray. We can get a taste of what is to come and build on 240 chart from this morning - expect to see more amplification on the 12z hopefully slightly more east based. A SSW appears almost certain albeit a minor one we have not seen a SSW since early 2013, I cannot draw even the slightest hints of February 98 - how someone could write of the winter it's beggars belief in my honest opinion.

Nice distinguishable polar low on that satellite imagery to NE of Faroe Islands. The national forecast had 90mph for the north of Scotland, 80mph through the central belt and 70mph gusts as far as Newcastle if my memory serves me right. batten down the hatches.

I sense today provides a reason to be more upbeat. Approaching mid month a cold snap/spell of arctic origin holds some weight - with it being cyclonic I'm sure there would be scope for widespread snow events, as illustrated by charts below:

A wise call David. I'm relying on severe cold taking hold ideally before mid month to really drag down CET & this has to start being seen in the model output ASAP. The sensible side of me is going for 4.6C hey ho. I'll refrain myself from making any changes sticking with 2.6C, which is hmmm.

Hi Amanda, it is very far away take it as you will. For south London gusts in between low to mid 60's which is quite unusual for London too far away to be taken seriously but a mobile spell of weather is coming so the potential is there.

Hi, I'm sure you will have a yellow wind warning. Top gusts in the North East around the mid 60's going by latest data not that bad this may change so stay tuned.

Surely you lot are accustomed to such high wind speeds? Not disputing the dangers, it seems more populated parts of Scotland are going to be hit hard such as Inverness, Aberdeen ect which may be the bigger story out of Storm Henry rather than usual bruising with Outer Hebrides taking the beating.

There's plenty of bugs in Liverpool.

Someone forgot to turn the lights out!

A monster ridge going up west coast WAA going polewards which can only be a good thing, it seems to be the torpedo hitting its target for U.S. how we will fare going forward is much more uncertain.

Fairly disturbed.. I reckon think there could be transitory snow almost anywhere in the next 10 days not exclusively for hills. No winter wonderland in sight - this is turning out to be quite a frustrating saga.
