For snow lovers, the chart to look at is https://www.snow-forecast.com/maps/static/uk/next3to6days/snow 3-6 days ahead showing widespread accumulations except for the SE (but I've found this site optimistic in the past)
The more conventional GFS shows as yesterday LP rolling through today, Thu 27th (but further south and not as deep; the BBC last night was in two minds as to whether this one would connect with the jet and deepen or not), Sat 29th, Tue 3rd (over the Isle of Wight with some quite cold air; looks the best chance of snow for S England), Sat 7th; cold zonal flow finally disrupted by ridge of HP, tentatively in the wake of the last LP but with a strong ridge to Scandi Wed 11th (but as noted yesterday, GFS keeps deferring this. If it happens there's even a chance of a weak easterly!)
ECM ignores a defined LP on Thu 27th but has the others in more or less the same place at the same time. FAX has the Thu feature at 991 mb in the Channel.
GEFS cool but with a short-lived spike of mildness most marked for the S on Sat 29th that wasn't there yesterday but has shown up in previous runs. Generally wet but drier early this week for the N than I would have expected from other charts
