HERE IS MY LATEST ANALYSIS FROM THE OUTPUTS OF THE WEATHER COMPUTER PREDICTION MODELS FOR TWO WEEKS FROM TODAY WEDNESDAY JULY 2ND 2014.
THE CURRENT GENERAL SITUATION. A ridge of High pressure will gradually move South towards northern France while a strong SW flow ahead of a trough reaches NW Britain through the day.
HEADLINE Rain at showers at the weekend and start to next week then becoming drier especially in the South and SW.
GFS The GFS operational today maintains the theme of a breakdown in conditions for all at the weekend as Low pressure feeds down from the NW. This then lifts slowly away North early next week as pressure builds once more from the SW with some fine and pleasant conditions for all before the trend back towards a slacker pressure feed over the UK retuens a risk of some showers late in the run. The GFS Ensembles still show a build of pressure next week behind the weekend's rain but High pressure is kept more towards the SW with Southern and Western parts benefitting from this the most on occasion with cooler weather with some outbreaks of rain most likely towards the North and NE of the UK extending to other areas too at times.
UKMO UKMO today shows Low pressure to the North of the UK at the end of the weekend and well into next week positioned close to northern Scotland with a blustery West or NW flow with rain and showers at times and much cooler conditions than currently.
GEM The GEM operational today is better than yesterday morning's run with Low pressure lifting away from the UK by midweek last to leave the East Coast where some showers may last into Thursday. The ridge from the Azores High then commands proceedings at the end of the week though it declines over the weekend as a broad upper trough slips South down Western sea areas to deliver the risk of showers to the South and West at the end of the run with the best conditions then transferring towards the East.
NAVGEM NAVGEM shows Low pressure early next week giving way to better conditions with time in association with a large Azores High. However, winds will remain West or NW and the North and West remain at risk of cloudier and drizzly conditions spilling in from the Atlantic at times.
ECM The ECM operational today maintains the general theme that Low pressure affecting all parts of the UK early next week loosens it's grip by midweek as pressure builds from the SW. The axis of the ridge is still a little too far South to give the very best weather but a North/South split later next week looks the most likely outcome with the South benefitting from bright and warm conditions but with large amounts of cloud at times while the North continue to run the risk of Atlantic troughs bringing rain across on occasion in the stronger Westerly feed there.
MY THOUGHTS The pendulum on the model outputs this morning's output has swung back slightly towards set fair conditions to predominate for many after the generally unsettled period Saturday to Wednesday of the coming week. The GFS Ensembles are a little worrying but those aside and the fact that wall to wall sunshine and blistering temperatures are not shown from any output there is sufficient clarity from the majority of model runs that the weather later next week and beyond will become pleasant for many with broken cloud and light winds and more particularly in the South warm at times with sunny spells closest to a strong Azores ridge and never more than just the chance of a local afternoon shower. This pattern mirrors quite well the pattern that has evolved quite frequently this summer so far and as a result I think few complaints are likely if this morning's charts verify. There is the prospect of a Westerly feed delivering more cloud and occasional rain at times in the far North but even here some drier periods in between will occur with temperatures never particularly cool. So all in all a welcome step back towards more pleasant conditions after the weekend rain than shown yesterday morning with no exceptional weather likely anywhere over the subsequent 10 days or so.
