I dont think it helped all that much and cannot remember having a frontal LP system before the main event before, that usually happens after the best convergence driven showers have dumped their load. I remember in the 2009 February Thames Snow Streamer, 2 days later the was an area of Snow from a frontal system that impacted the SE and areas to the North and West of London did best along with the Chilterns, ironically there was too much Mild air for Coastal Kent and Essex entrained with Mild Sectors and South Easterly winds making it the wrong side of marginal.

I know the snow chance are still possible for tomorrow but it feels like this spell is running out of steam and on its way out. Snowfall would place this in my Top 10 for my lifetime but closer to 10 than 5 probably settling around about 8th. Depth of Cold would put it around 7th over the last 48 years. The problem with this spell as others have noted has been the build up, you simply cant expect the temperatures 2 days before to be 12c, the day before 7c and with no frosts to cool the saturated ground down there really was going to be problems with laying snow. Snowfall intensity has been pretty awful and nowhere near the 3 big spells of 1987, 1991 and 2010. All 3 of those spells were the traditional Sunshine and Shower type Easterlies with convection growing upto 15,000ft and Thundersnow reported in all of them, this spell like the last Beast in 2018 have relied on showers coming along through a stratus deck with no sunshine between the showers. So again although not anywhere near the best it certainly has been good enough for sledging, snowman building and Ice Days which is what you would expect from a Scandinavian sourced airflow in early February. Hope the cold holds on and any Atlantic wetness is deflected away, would love to see a week of cold Scandi High dry weather to get that cold into the ground and who knows the next snow to come after that could be of a much better quality.

Icicles are starting to appear here now hanging off the eaves sure sign that we had about 4 hours of above zero temperatures this afternoon and the temp is once again nosediving. Sorry to say going to be an ice skating rink tonight again. Sublimation today has been pretty bad as well, the 8cm on the grass from first light has reduced to 5cm now and even with some hefty snow showers in the last few hours.

SST's having an effect down in Shoebury but temps wont get much above 0.5c today and with the dewpoint being way way negative everything that falls should still be white. We are about 6 miles west of you and a full degree colder so no Sublimation of the snow at all and no icicles on the roofs or car bumpers yet so plenty cold in the ground here. 30NOV 2010 To Dec 02nd 2010 that streamer had constant snow for 72 hours so we have to make it through till tomorrow morning around 8am to beat that

Easterly wind is really affecting the temp down here as well, Shoeburyness just hit 1.3c in an East wind and my weather station has crept above freezing for the first time since 7am on Sunday morning. We are now at 0.2c here. But crucially the Dewpoint is -5c so no chance of anything other than Snow falling.

Having had a look at some charts tomorrow looks really good for your location. A convergence Zone sets up through Mid and East Kent and also parts of Sussex bending away into the English Channel. Could be some decent dumps of Snow from Medway Towns Eastwards to Dover, and places like Brighton across to Folkestone and maybe Eastbourne etc could get in on some decent falls tomorrow

Just woken up to some idiot in a Mercedes SLK whose back wheels are spinning around like a Hamsters Wheel, he cant even make it up a small incline and is making a right old mess and skidding sideways. Anyway a good few cms have fallen probably around 4cm extra atm so upto 9cm on the grass now with is untouched and the car has some impressive totals on it. Will get some pics in a bit, bin day today if they even turn up
