GFS Op - HP steadily moving to N Norway 1025mb Sun 13th with E-lies developing (the dreaded Haar for the E Coast) and at the same time pressure dropping over England 1010mb in from Belgium and similar from the Atlantic over W Ireland. These two LPs merge into a centre which bumbles around off NW Scotland for the following week, to Sun 20th, with a SW-ly cast to Britain's weather, the usual pattern, unsettled in the NW and fine in the SE (but not as hot as currently). On the 20th this LP dips further south before moving off to Norway and trailing (shock! horror!) cool N-lies on Wed 23rd. But HP then resumes from the SW as so often this summer, though looking less firmly established with small (thundery?) patches of LP embedded up to Sun 27th.
ECM - the same sort of pattern as GFS but more influence from LP as from Sun 13th, developing a centre 1000mb N Ireland Tue 15th and associated lower pressure for England. The main LP centre first retreats somewhat and then returns as a trough stretching NW-SE down to Cornwall on Sun 20th
GEM - echoes GFS but although pressure is on the low side by Sun 20th, there's no sign of any northerly developing.
AIFS - London, peak heat tomorrow at 31C (Sat), then maxima steadily dropping and in the range 20-25C from Tue 15th with frequent but small amounts of rain for the next 10 days. Edinburgh, peak heat now with both Sat and Sun at 25C, cooling but reviving to 22c Thu 17th, thereafter in range 15-20C. Rain in blocks, Tue 15th, Sun 20th and Wed 23rd
GEFS - In the S, warm (+5C from norm) to Tue 15th, then a dip before a long period with mean 2 to 3 C above norm, though with very little agreement between ens members from Fri 18th onwards. Very small amounts of rain randomly in a number of runs from Tue 15th. In the N, much more above norm to start with, but then the same dip and recovery; rain in most runs from the 15th and moderately heavy at times, less so in NE
