GFS Op 00z; trough moving in from the west centred 1005mb N Ireland Tue 15th but LP extended across Britain generally. Pressure then remains low but slack for the following week, typically 1005-1010mb (with potential for thunderstorms widely - or is that wishful thinking?). Lower pressure then focuses on N Scotland; 1005mb Wed 23rd, 1000mb Sat 26th, and another centre approaching Tue 29th, all indicating the common split, NW unsettled and SE fine. Still very warm in the SE at times.
ECM; similar to GFS but the 'slack' LP is more emphasised in the south, until Tue 22nd when it pulls back to the NW and HP builds from the south.
AIFS; London, cool Tue 15th with a little rain - warmer (maxima ca 25C) to Mon 21st when again a dip in temp with rain - maxima recover to low 20s with more rain around the 26th. Edinburgh, the same timing of dips in temp with rain, but maxima between dips close to 20C
GEM persists with LP off N Ireland/NW Scotland after Sat 19th, with warm SW-lies for all, and definitely hot for the SE from Tue 22nd
GEFS; In the S, after a dip on Tue 15th, mean temp and most ens members slightly above norm for a week, then back to norm. More rain than shown yesterday, still not a lot, but a few runs suggest the occasional downpour. In the N, temp profile similar, bur rain likely at any time after Tue 15th in moderate amounts, timing is different in different ens members.
