The BBC look ahead last night showed the LP currently spoiling summer for he south as a persistent and even enlarging feature before finally pushing off into the Continent later this week, with bands of rain affecting anywhere south of Manchester/Leeds in a random fashion. FAX agrees and shows a mess of fronts over S England until Thu 1st. But WX maps offers something much warmer and drier for the S in week 2, and although suggesting somewhat damper for the NW at that time, not dramatically so.
Jet fragments around UK to start with, then dipping S over Spain from Thu 1st gradually moving N again and breaking up over the UK Wed 7th before re-forming well to the N on Mon 12th
GFS - HP over Scotland gradually extending a ridge S-wards and just about holding on between the LP leaving the S and LP pressing from the Atlantic until Wed 7th when the HP focus shifts to a ridge from SW across UK to Norway and a close approach of LP to Hebrides. The ridge strengthens a bit, but is still there Tue 13th, similarly squeezed from both sides with LP near Rockall and something vaguely thundery over France (but the latter this time with a warm centre unlike the present one)
GEFS - significant rain for the S until Thu 1st then most runs edging warmer with what looks like a showery pattern of rainfall through to Tue 13th. Scotland up to 5C above norm and dry until about Mon 5th, the temps back to norm and rain becoming more frequent as time passes though not large amounts.
ECM - disappointing as after Wed 7th (it's like GFS up till then)LP on the Atlantic gathers strength and pushes in to be centred over N England 1000 mb Tue 6th with a notable cold pool at its centre.
