Its ok, i have a mate in Clacton thats a genius with Wi fi and cameras, he spent about a week tracking and finding the signal that goes to the lampost outside his house, now he can turn it on and off from his pc.

It is not those drivers (like yourself) who are prepared who are the issue, it is the rest who are unprepared that cause the jams and traffic chaos.

I can honestly say, I have never caused any traffic jams in the snow due to my under deflated tyres:nonono:

@yamkin you had the Severe Winter Weather - Level 2 alert yet? Looks good :good:

Croydon Borough Council & Croydon's Emergency Services have received updated memo's regarding the severe oncoming beast onslaught. My understanding is that other Borough Councils & Emergency Services have been updated as well.

Afternoon Guys:

So as of 06z today these are the following notables for our region & timelines

90% confidence now

Sat- Winds direct SE flow - dewpoints dropping as the day progresses circa -5c peak temps AM ~4c -afternoon temps pegging back early maybe 2c- maybe the outside chance of a flurry ( low )

Sun through the day- Winds backing more Easterly 

Approximate -10c isotherm times ( ahead of GFS ) 2pm Norfolk / East kent - 6pm London - Midnight to the shires

Spread is about 6 to 12 hours ( mainly slower not faster ) - UKMO raw the fastest with the fastest flow -

Sunday Eve Snow ?

This depends on final allignement & because its still 5 days away its still around     60% confidence 

However late eve - Benchmark maybe 8pm Snow showers will start pecking away at EA & Kent - Allignment at this stage is favoured 60% Thames streamer & Essex / Suffolk + London / shires later - 35% Mid kent streamer 5% East kent only - 

EA also included in slow 

*** Remember for widespread snow Thames flow is the best ***

By Monday the consensus is that there should be a window of 24 -36 hours where we peak on shower activity Spreading across the region

Conservative totals ( you have to put zero just incase ) 0-10cm - Up to 20cm in the peak shower zones.

**REMEMBER THIS IS ONLY DAY 1**

Post this things become more & more interesting - There may be a lull across weds ( with deep frost weds ) however attention turns to activity over Scandi as a wave moves west from Siberia -

The images below show the cold, but more impressive is the cold attached circa -28c ( follow the kink )

This kink & wave has a wide cone of where it could go - ( Think hurricane track & cone ) but at the moment the UK is at the centre point of the track in the mean Ensembles -

GEFS is a bullseye

This brings the chance of even more substantial snow & probably the peak of the cold - Thurs 

Estimates -15/16 air ( with an outside chance of -18c )

A real deep snow maker-

If not, still lots of snow around / troughs etc-

This would be my guesses at this stage which to be fair are pretty much just for fun ( all be it with a hint of reality )

London 2-4 inches

West of London 0-6 inches depending on shower speead-

Essex / Kent - Suffolk 3-18 Inches - again dependent on flow allignment.

Duration of cold ( starting Sat ) 7-14 days(

Lovely post Steve. Fingers crossed for Mother Thames to fire up....will be watching here intently as the first port of call on any Thames train....

Slight change of wording from the met today, looking 'mainly dry' at the beginning of the week. Hopefully they are just playing it safe..... 

UK Outlook for Monday 26 Feb 2018 to Wednesday 7 Mar 2018:

It will be turning much colder next week. Monday and Tuesday will be mainly dry with sunny spells, but snow showers will develop across some eastern and southern areas, where fresh winds will make it feel bitterly cold. Through the rest of the week it will remain cold with an increased risk of ice, frost and snow showers. These will be heaviest and most frequent in central and eastern areas, and some spells of more prolonged snow are possible at times, particularly in the east and across southern England. The cold weather will continue into early March, with the northwest seeing the best of any brighter weather, and here it may be less cold at times, although brisk winds will continue to bring a marked wind chill.

you got two confused smiley reactions in the MOD thread, why is that, there is another SSW isn't there?

Intense SSW is in action & the models have picked this up, hence today's fluctuations. No need to be concerned as the current Beast From The East is still on course.

The graph had to be extended to new parameters to accommodate the intensification of SSW. This intensification is the result of the energy from the recent CME (Coronal Mass Ejection) from the sun. Increased blocking.
