FAX - fronts crossing Britain under influence of LP to the north or northwest, but the LP is only 995mb at its deepest, and the fronts ( today, Mon 17th, later on Tue 18th) looking active in the north but breaking up as they run south into a ridge of HP lying along the Channel.
GFS Op 0z - the LP mentioned in FAX crosses over to central Scandinavia, and persistent LP there to Mon 24th brings light northerlies for Britain - cooler, but too far away to imply rain. On Tue 25th a local LP which has been brewing to the SW reaches Cornwall 1000mb, also running east to Scandinavia. Northerlies then resume, strengthened a little by another small LP 1000mb running through N France Fri 25th. Pressure remains fairly high to the west of Britain from Mon 17th onwards.
ECM - agrees with GFS to Mon 24th, but then shows pressure dropping over the Atlantic with a large but shallow LP 1000mb and Britain under slack pressure between that and the Scandi LP.
AIFS - London, maxima after today dropping to 25C over the weekend and then further to 20C through to Fri 28th. Traces of rain next week, then heavy on Mon 24th and Thu 27th. Edinburgh, maxima slowly decreasing from today's peak to 15C Mon 24th before rising a little. Rain Tue 18th, Fri 21st and Thu 27th, a little at other times
GEFS - mean temp first dropping to norm, then below norm by a couple of degrees from Mon 17th to end of month. In tS England, chances of rain from 17th but only becoming significant from Mon 24th onwards; in Scotland and N England this is inverted with quite high chances of rain from 17th and a few days after, then chance of rain tails off.
