East Herts Snow

Must admit, this run does look more the South West's turn for snow.

Only downside in the short term is the colder air pushing more South is that the ppn has moved into Northern France at +108 onwards. Overall a colder, but dryer run for Southern areas, although Tuesday/Wednesday snow event has been upgraded, especially for South Wales and West Midlands.

Well out to +102 and everything shunted South by about 100 miles. Southern Wales and South West Midlands look best for snow thus far....

Usually the definition that people use to divine the North/South boundary (in England) is to use the Watford Gap motorway services in Northamptonshire (South Midlands). The 'starting' snow boundary at present seems to centre around this boundary line and is the average starting point from all of the various weather charts. This is only a very rough guide and the eventual outcome maybe between 50 to 150 miles North or South of this line. However this snow boundary line is projected to move further South later on next week.

Yep, same here. Drove 25 miles from Enfield, North London, to Buntingford in East Herts and it took nearly 3 hours. Admittedly the snowfall was very heavy for 2 hours, continious traffic up the A10 between Enfield and the Puckeridge turn off to Bishops Stortford. Never seen traffic so bad in 18 years of driving, not pleasant! Had to bypass around Puckeridge through Braughing and then navigate some steep hills, how I got back I do not know!

Lowland receiving westerly winds next to a warm Atlantic ocean. GFS predicted these temperatures for that region today. Will cool back down later this afternoon.

As ever with these cold v mild, its an 'all or nothing' deal, where you can end up with just a horrible wet mushy outcome, or a full on snowstorm as what happen mid February 1978. The current synoptics are pointing to this possible outcome, who knows what will happen, i.e. will mild weather push through straight away, or will the colder dense air hold on for longer and a snowstorm ensues? Mild will eventually win through, as it always does, just don't know when yet. Either way as TEITS has stated these current charts are simply amazing and anything could happen! Hi snowingman, have you got a link to this chart? Cheers

I accept what you are saying Tommyd1258, but this still may make Christmas Day interesting at the very least for some areas, as the below may point out. If this run were to verify, Christmas Day could be brilliant for a lot of the country, in particular the Southeast 528 Dam across the whole country.... Plenty of PPN around...and look at how tight those isobars are across the SouthEast, coming off a warm sea, could be a repeat of the snow event last Thursday. However there is a warm sector to the low across parts of Kent, however if this was to move further East. Ground max temperatures maybe a tad too high especially near the coasts NB - On Betfair only one snow flake falling over Buckingham Palace weather centre constitutes as a white Christmas.

Charts at +108 show quite an intense low off the Kent Coast (further West on this run). 528 Dam line across the Midlands, could be a lot of snow to the NW of this low. At +114 low moves further East and brings the 528 DAM further Southeast and with it the chances of snow for some areas on the big day....... Upgrade alert for Christmas day for potential snow.... 528 DAM clears whole country and more PPN on this run, could it be a white Christmas for Southeast?

Good old Warm London for you, since moving out of Enfield to rural Hertfordshire, I've noticed how much colder it is and the snowfall is much less marginal (only 20 miles North of North London).

I suspect that the built up London heat sink is possibly pepping up the ppn a little. This sometimes helps to make thunderstorms more in intense during the summer.

Bexleyheath = Sweet spot for snow!

We just had that in Buntingford, East Herts, heavy to very heavy snow for about 30-45 minutes. Left a few cm's!

Enfield, North London in a prime spot for snow. NB - Not suppose to add this attachment, but just this once as it shows how heavy the snow will be for a while.

For you folk in North London, your about to receive a period of heavy snow! Front is moving quickly though, so won't last a long while, but you should get a covering.

I think the Chiltern Hills causes this with uplifting. Seen this happen in the last three years, front moves from N/NW and the ppn suddenly intensifies when it hits the Chilterns.

Wow, have had heavy snow here in Buntingford, East Hertfordshire with an additional couple of cm's. Topping up our 7 inches of snow from the other night.

Definately keeping an eye on this thread, as the snowfall you receive will hopefully carry on into East Anglia afterwards. Hopefully it will start to slow down over the Midlands, as it is forecast to move through quite quickly.

Nice one, how much snow have you had and was this from Thursday night's snow event?

Nah your not allowed to have any snow in the Midlands, we want more in East Anglia.....! :lol: Only joking, hopefully this time its the Midlands turn for decent snow! :lol:

Great picture there shadowcat, looks like parts of Hertfordshire were the sweet spot the other night!

The North Sea is like one giant snow machine due to the high sea temperatures.

I notice that there is a LOT of activity just off the North coast of Norfolk. Another streamer kicking off? :lol:

You really want the showers to head West...... :o May still be interesting tonight.

Very good informative post there neilsouth. You always be in a prime spot in Kent (as it juts out into the North Sea). I remember the cold spells during the 1980's and large parts of Kent being cut off in huge snowfalls (especially East Kent). Keep the faith mate!
