GFS synoptics have the LP to the SW drifting N and filling by Wed 17th. after which a zonal flow sets is. One LP in this zonal setup gets uncomfortably close to Scotland Wed 24th and eventually pushes cool NW-lies down across all the UK Sun 28th as its remnants work their way into the N Sea
GEFS temps close to seasonal norm, perhaps a little cooler around from 24th as noted above, rain after today in the S gives way to a few days of dry weather in SE, then mostly small amounts in England from 17th onwards. Scottish temos rather above normal at first, but rain is more general and after 24th quite significant amounts.
ECM similar to 17th but then not zonal; trough of LP from Iceland to France by Sun 21st - it's down the west of the UK so the east may be warmer, even looking a bit thundery in the S on Mon 22nd
