HERE IS MY LATEST ANALYSIS FROM THE OUTPUTS OF THE WEATHER COMPUTER PREDICTION MODELS FOR TWO WEEKS FROM TODAY SUNDAY JUNE 8TH 2014.
THE CURRENT GENERAL SITUATION. Low pressure to the SW of the British Isles will move slowly Northeast over the Eastern Atlantic while filling slowly with a slack Southerly airflow across the British Isles.
GFS The GFS Ensembles today show High pressure continuing to be programmed to ridge up towards Southern Britain later this week with some fine and warm weather likely for Southern Britain. Low pressure is more reluctant to leave far Northern areas with some further rain at times and the long term trend this morning is for High pressure to ease away NW and the threat of showery Low pressure to move down from the North in Week 2 with showers most prolific across the SE.
UKMO UKMO closes it's run today with High pressure across Southern and Western Britain along with some warm and bright weather receding away towards the NW allowing a showery trough to move down over most parts from Scotland next weekend.
GEM The GEM operational today is probably the best of the output this morning if it's fine, very warm and sunny weather you strive for as it shows High pressure having moved up into Southern Britain later this week drifting slowly East into the North Sea with a very warm and continental feed of SE wind over Britain to start week 2 with most areas dry and sunny.
NAVGEM NAVGEM is also keen to build High pressure close to Southern Britain later this week and holds it in situ out to the end of the run close to the SW. The net result would be dry and fine weather with some pleasant sunshine and any rain restricted to the very far North.
ECM The ECM operational today also looks pretty good if it's fine weather your after as it too builds Hgh pressure up across Southern Britain later this week with some fine and very warm weather likely for many, especially in the South. Later in the run High pressure slowly drifts North and NW with a weak trough crossing South next weekend perhaps with a shower before high latitude pressureNorth of the UK runs the risk of showery Low pressure returning nearer to the UK later in week 2.
MY THOUGHTS All in all this morning the output looks good as all models support a strong build of pressure close to Southern Britain later this week. To obtain a lengthy spell of fine Summer weather we would ideally like this to drift across towards Scandinavia and maintaining a ridge SW through Britain to the Azores but that looks unlikely. Instead it holds close to Southern and SW areas bringing nonetheless plenty of warm sunny weather before it's desire to drift North towards a position NW of the UK could open the door to either the NE or West of showery Low pressure regaining a hold later in Week 2. However, that is a long way off and is very uncertain at this range with the more certain prospect of some fine and warm weather with variable cloud cover to be enjoyed for many before any risk of that occurs.
