I see from the risk matrix that if the Thur/Fri becomes more likely and the impact stays the same it could upgrade to Amber/Red. 
Hope this isn't done lightly as it will result in Schools etc closing down when there is so much uncertainty.    Also yellow warnings have covered 5-10cm of snowfall in the past adequately.  Fair enough if it is for a populated area that they think will receive 20cm plus.

Updated met office warning from 7am tomorrow to 2pm Friday

Heavy snow has the potential to cause disruption on Thursday and Friday.

Reason for update

The warning area has been trimmed away from parts of central and northeast Scotland and moved from high to medium impacts.

An area of low pressure will move across the UK on Thursday and Friday with snow developing across Wales and central England early on Thursday morning. This is expected to move slowly north during the day, becoming slow-moving across north Wales, northern England, Northern Ireland and southern Scotland during the afternoon and evening before slowly clearing southeast on Friday.

Snow will likely turn to sleet or rain at times at lower elevations, especially in the south of the warning area, as well as near eastern coasts. At low levels including major cities such as Manchester, Liverpool and Newcastle accumulations are expected to be limited with a small chance of 2-5 cm falling. However, significant snow accumulations are possible over hills of northern England (including populated areas of South and West Yorkshire), Northern Ireland and southern Scotland.

Here, 10-15 cm is expected quite widely above 100 metres, with a chance that 25-40 cm could fall in some places . Additionally, there is potential for strong winds, which may lead to blizzard conditions and drifting of lying snow. Ice is likely to develop widely on Friday night as this system clears away.

Level 3 cold weather alert extended until Monday morning

Current alert level: Level 3 - Cold Weather Action
Issued at: 10:40 on Wed 8 Mar 2023

There is a 90% probability of severe cold weather/icy conditions/heavy snow between 0900 on Wednesday 08 Mar and 0900 on Monday 13 Mar in parts of England. This weather could increase the health risks to vulnerable patients and disrupt the delivery of services. Please refer to the national Cold Weather Plan and your Trust's emergency plan for appropriate preventive action.

This is an extension to the previously issued alert on Monday. Very cold weather is expected across most of England this week, with widespread frosts overnight and temperatures struggling to rise much above freezing in some places during the day. A band of rain, sleet and snow will move across the southern half of England on Wednesday and overnight into Thursday, with icy stretches developing. To the north of this should stay dry, although a few snow showers are possible in the northeast, but very cold temperatures will see a severe frost develop.

On Thursday, the focus shifts slightly further northwards, with another band of sleet and snow pushing northeastwards across central and northern England. There is some uncertainty as to how this band progresses, with current forecasts bringing that area of sleet and snow back southeastwards on Friday to affect parts of southern England once again. Further outbreaks of snow are possible over the weekend, as well as widespread frosts and icy stretches. Milder temperatures look like they may start to encroach from the southwest through Sunday, confidence on this however is currently low.

An update will be issued when the alert level changes in any region. Alerts are issued once a day by 0900 if required and are not subject to amendment in between standard issue times. Note that the details of the forecast weather are valid at the time of issue, but may change over the period that an alert remains in force. These details will not be updated here unless the alert level also changes, the latest forecast details can be obtained at the following link: http://www.metoffice.gov.uk/public/weather/forecast/#?tab=map

BBC monthly outlook
Wintry weather will tend to shift northwards

Wednesday 8 March to – Sunday 12 March
Snow in many places. Milder by the weekend

Monday 13 March to – Sunday 19 March
Mild in the south, chilly in the north

Monday 20 March to – Sunday 2 April
A similar pattern could linger

https://www.bbc.co.uk/weather/outlook 

Arpege has a snowfest lasting almost 24 hours from Thursday morning for a large area covering the North Midlands/North Wales/NW England/the western two-thirds of Yorkshire/NE England. Perhaps a snow/sleet/rain mix toward western coasts/into Cheshire.

The sweet spots look like being the Peak District & North Wales, where I wouldn't be surprised to see in excess of 30cm for areas with some altitude

Thomas you-know-who was suggesting 40cm for parts of the Peak District; and although he didn't say it, the synoptics imply there will be a lot of drifting.

Text message to me (as registered as at risk on account of age) from SSE networks, responsible for electricity network here ...

"a Weather Warning status in preparation for a period of unsettled weather which could impact the electricity network across central southern England on Monday. We are expecting high winds ..."

MetO forecast 47mph gusts, BBC 53mph; fairly wild but doesn't seem so bad as to generate the warning above.

Apparently we were on the cusp of a major power nationwide power cut about four days ago but escaped with a more than a little help from our friends on the Continent.

The met office have cancelled the level 3 cold weather alert and issued a new Level 2 alert for parts of England

Issued at: 08:52 on Sun 12 Mar 2023

There is a 80% probability of severe cold weather/icy conditions/heavy snow between 1800 on Monday 13 Mar and 0900 on Thursday 16 Mar in parts of England. This weather could increase the health risks to vulnerable patients and disrupt the delivery of services. Please refer to the national Cold Weather Plan and your Trust's emergency plan for appropriate preventive action.

Much milder weather covers England during Sunday. Remaining very mild overnight and into Monday with wet and windy conditions. Snow thawing rapidly. Timing of much colder air spreading from Scotland later on Monday is associated with low confidence currently, however confidence is higher that colder air will spread southwards to affect all areas during Tuesday. Confidence is also low with regard to snow amounts occurring on Tuesday with showers perhaps merging to give more organised spells of snow in places.

An update will be issued when the alert level changes in any region. Alerts are issued once a day by 0900 if required and are not subject to amendment in between standard issue times. Note that the details of the forecast weather are valid at the time of issue but may change over the period that an alert remains in force.

We were indeed... firing up one of the mothballed coal power plants also helped.
