Yorkshire & Lincolnshire Regional Thread - January 13th 2013>

[Just Before Dawn]

Yellow warning issued for SW third of UK for blizzards and upto 15cms locally. Rarely you see such words on the metoffice, but they are clearly concerned. As yet, nothing for Yorkshire, it all depends if the front moves across or not. If it does, we could get 10cms perhaps. Worth watching.

Indeed, the path of the LP and associated fronts are critical in terms of whether the front and any associated ppn can cross the whole country.

Yeh an interesting one for our region re fri and the wkend.Ideally we want energey ejecting se under our region to keep us on the cold side n hope the lows follow suit each time.I personally feel we'll all see a decent amount of snow sat onwards and keep on the cold side of things. Good signs further down the line as well.

[Harsh Climate]

This is a definate keeper!

A growing trend now emerging on all the models that this snow in the west on friday could reach us.

Also earlier than friday, might be worth keeping an eye on this little feature to hit north western most parts of england on thursday

Could be something significant and further south than currently progged.

Snowing again here in Scarborough. Didn't see this one coming! fairly heavy too!

[Cheese Rice]

Problem is though the Met Office favour the UKMO output.

This cold spell would have been better if the cold was in place first, and the snow followed, like the previous cold spells, instead of getting the snow beforehand, and then it thawing a lot.

Still have the majority of the snow here, temp at -1 not gone above 0 all day so no thaw other than on some roads Looking forward to the rest of the week!

Ice will be a massive problem in the coming days here, especially on side roads and pavements.

This cold spell would have been better if the cold was in place first, and the snow followed, like the previous cold spells, instead of getting the snow beforehand, and then it thawing a lot.

The evidence doesn't really bear that out- it wasn't generally cold enough for snow prior to the widespread snowfalls of the 17th/18th December 2009, or the ones that hit E Scotland and NE England on the 25th/26th November 2010.

The main issue is rather that a thin, patchy snow cover is far more prone to thawing in sunshine and/or temperatures slightly above freezing than a deep and full snow cover- this is due to surface albedo as a deep/full snow cover strongly reflects heat, especially solar energy. Here at Sandhutton I'm seeing the same issue although most grassy surfaces are holding onto a couple of centimetres.

Yeah, good point, we had 5cm here and it's thawing rapidly in the sun. We had 15cm in February last year which managed to survive intact for 24 hours after in temperatures above 4C.

It's just painful watching Norfolk copping the snow - the scenes are a world away from here. It's enough to drive a person to insanity!

This is a nice top up! The thawed areas now white over again. Perhaps 1cm and still coming down.

Fantastic explanation. Just what I thought. Still decent enough coverage on grass n hedges, just a shame that hour or so of 1.6c did some damage. Temp since dropped down to 0.4c hoping for weekend.

UK weather: Travel disruption after fresh snow

Fresh snow across parts of the UK has caused further travel disruption.

Norwich airport is currently closed and trains between the city and Cambridge are running with delays after speed limits were imposed. Yellow warnings advising the public to "be aware" of frozen conditions and hazardous roads in eastern England and south-east Scotland have been issued by the Met Office. Forecasters said the cold spell would continue until Friday.

Snow has also fallen in other parts of East Anglia, as well as the East Midlands, south-east England, north-east England, south-west Scotland, Lothian and the Borders and Yorkshire and the Humber. Temperatures across the UK range between 0C and 4C but forecasters said sleet and snow could result in icy stretches overnight into Wednesday as surfaces freeze under them.

In other developments:

In Suffolk, police reported more than 30 accidents involving vehicles on roads overnight in the county and a gritting lorry crashed into a ditch during a snow flurry on the B1115 at Little Waldingfield near Sudbury

In Norfolk, more than 40 schools have also been closed because of the snow. Norwich Airport said it had been closed until further notice, advising people to contact their airline

The horse racing schedule has been affected, with Wednesday's meeting at Newcastle and Thursday's meeting at Market Rasen abandoned due to snow on the courses

Schools have closed across Wales, where widespread icy conditions caused delays on roads and the temporary closure of the A4067 between Glais, Swansea, and Junction 45 of the M4

Many roads in the north-east of Scotland are described as hazardous, including the A90 north and south of Aberdeen. A car landed on its roof after an accident on the B979 near the Tyrebagger. Aberdeen International Airport has already seen some cancellations and at least 15 schools in the area are closed

Greater Anglia trains said snow between Norwich and Ely meant services were running at reduced speed and warned passengers of delays of up to 15 minutes.

On Monday, snow across large swathes of England and parts of Scotland - particularly Aberdeenshire - led to a number of problems, including school closures and travel delays. Steve Crosthwaite, of the Highways Agency, said motorists should check the latest travel advice before they set out, check their vehicle was prepared for the conditions and take warm clothing and food. He told BBC News: "We are using salt to treat the road network and have ploughs and snow blowers on standby if necessary. Our traffic officers are working around the clock to monitor our road network, deal with any incidents and keep traffic moving."

Tasmin Jeff-Johnson, from the RAC, urged motorists to take sensible shoes and a warm coat on any snow-affected journey. She also advised drivers to take a shovel and pieces of old carpet to provide traction in case of breakdown. Three Met Office yellow warnings - advising people to "be aware" of severe weather - were put in place for much of the UK on Monday afternoon.

Eddy Carroll, chief forecaster for the Met Office, said: "With some very low temperatures over the next few nights we also expect ice in many places and people should be prepared for travel problems." The Met Office has issued a cold weather alert, warning of a 90% probability of severe cold weather or icy conditions until Friday in parts of England. The level three alert - one below a national emergency - warns the weather could increase health risks to vulnerable patients and disrupt services, and notifies the authorities to take action. The cold spell is being caused by an abrupt jump in temperatures high in the stratosphere, which can bring snow, forecasters explained.

Its already a problem for us. Having to use crampons to get round the fields as a lot of the snow has already turned to ice. We are kind of used to it here though, hence the reason why we even have crampons

Certainly interesting though it appears to change with every run (some showing nothing, some showing rain).

[ITSY]

Probably won't be as much of a nowcast as events yesterday and Sunday night, but I reckon there's a good 24-36hours before we know the fronts likely trajectory (for Friday and Sat).

[Les Penniston]

Still have the majority of the snow here, temp at -1 not gone above 0 all day so no thaw other than on some roads Looking forward to the rest of the week!

Hopefully getting more this week.

[Lincstim]

Our main Central Park has still got a good covering but most our roads around scunny are 85% clear with just slushy remains which will re-freeze tonight.

Fingers crossed for this weekends weather but we were definitely spoilt in 2010 lol

[Harsh Climate]

gfs 12z is a peach so far! Heavy snow friday evening. West of our region worst affected

[Aaron]

GFS brings snow, but the heaviest and most prolonged is confined to areas west of the Pennines and south of say Lincolnshire. Not sure I can bear any more disappointments. Hugely deflated by recent events to be honest.

Was in Mablethorpe earlier when a big snow shower came through there was hardly anythjng on the paths an roads at all but after 10mins the road an paths where covered the Snow was really Intenwe with massive Snowflakes wasn't expecting to see such Heavy snow.

I wouldn't mind if the heaviest was near the south of Lincolnshire

[Mark Bayley]

Does this chart include south yorks?

Yes, GFS would give several cm's of snow for our region, much more however for west of the pennies and the West Midlands. Hopefully Fridays band does reach us.

[Harsh Climate]

Does this chart include south yorks?

yes it certainly does, the bulk of the precipitation would hit west/south yorkshire first, then move across the rest of the region later. Heaviest falls likely to be the further south west you go.

That's providing that that chart is correct lol
