Met office pretty bullish on Thursdays event...

Seen a temp drop of a degree here in the last hour: 5.8C >> 4.8C with light rain.
hoping that cold air is starting to edge out that milder southerly already...

Must be patient today. It will all start as rain. It's currently 6c here in Cambridgeshire, it's only later into the evening when the transition starts and hopefully leave a covering of snow as it passes, then a very frosty night.

Everything running along smoothly

Snow from 5 till midnight

Radar looks great and the timing

Temperature s now peaking and should slowing drop

I live close by, in Greenford, and all i see on met office app is rain and sleet. Hope your right.

BBC London forecast suggesting accumulations over hills and maybe some slush over lower ground, oh well, be nice to see it falling under the lamppost if that's the case, just hope Thursday sees a better chance of accumulations in our area, though it may not hang around if the band moves too far north.

Any rain at the moment in our region is coming from showers that have developed in front of the frontal system. This maybe the area of lighter precipitation the models were clocking onto in the last few days.

cold front will slowly head east and will probably lose some intensity, the 3hr averages aren't exactly electric so its not going to be too significant in strength. If you use Net-weather radar, the 06z ECM would show rainfall rates that would equate to the two lower green colours. If that makes sense!

Also, the amount of information we have now is amazing I should say, we get insights into UKMO and ECM we could only dream of 10 years ago. I remember having to try and extrapolate a pattern based off a ECM wind speed map each 24hrs back in the mid 00s. Very different these days!!

Don't understand the negativity. The front will be over us for 4 or 5 hours near midnight, that is plenty of time for evaporative cooling to take hold.

Cos it'll be rain

Exactly the same rhetoric from Look East too. Likely to see snow falling but not much settling going off that although the Met office chart from their live cast earlier showed snow from 5pm to midnight over most of the region

TAFs for Gatwick and Heathrow mentioning snow after 19z, temporary heavy snow showers between 20-23z

Yes. But this is the thing Nick - PROB30 TEMPO 2920/2923 0500 +SHSN BKN004. Its a Prob 30 which means that the +SHSN will most likely not happen. Now if it was a prob 40 that would be a different matter. The tempo means that even if it did happen it would last no longer than half the period covered which would mean 1.5hrs at best. Hence my pessimism.

Only prob 30 & no more than 1.5 hrs.

Yes, not the best probability is it. Though even Luton Airport has 30% prob of snow and it's 150m asl according to streetmap/OS. Would expect better snow probs up there so not so sure the probability on TAFs is always a good guide.

Still looking as close to marginal as we could get, looking at GFS, it puts the 528 line in front of the main band just as the heavier stuff moves in around evening time.

By midnight the 528 line is well into France and precip band centred over our region.

Ive used the 528 line a lot in marginal set ups before and it tends to work quite well.

Certainly a desperate lot to see snow aren't we! Let's hope Thursday brings something to remember, because an hour of wet snow and slush will be a bit underwhelming after the build up

Yep, still at least we do have a chance at snow this week, there have been some winters where basically nothing happened all seasons, so small blessings I suppose!
