FAX - HP 1034mb Shetland today drifting southwards to E Anglia 1024 mb Sat 25th and slowly cutting off the easterlies, while cloud on the fringes of Atlantic LP may touch on the west coast. On Sun 26th the HP extends to the SW, and SW-lies set in over N Scotland ...
GFS Op 0z - ... but then the HP reverses direction and crosses Scotland on its way back northward, to Norway 1030mb Thu 30th with E-lies returning to the Channel. The high pressure just about hangs on for the BH weekend (to Mon 4th) but a trough is then moving in from the NW and develops as a closed circulation LP 995mb Irish Sea Thu 7th.
,
ECM - agrees with GFS though E-lies from Thu 30th are more from the NE, and so likely colder. In this model the HP then moves to the west, so no new trough, and LP over the Baltic continues to feed in N or NE-ly winds
AIFS - London, maxima rising to 19C Sat 24th, and after a dip, back to 22C Mon 4th. Dry and sunny until then, but from Tue 5th a little cooler with a little rain. Edinburgh, pattern as for London but 3 or 4C cooler, and rain from Tue 5th quite heavy
GEFS - mean temp rising to 4 or 5C above norm in the next day or two, dropping to norm or a little below from Mon 4th (gradually in S, more suddenly in N) and a number of cold outliers appearing amongst ens members. Dry until 3rd or 4th, then chance of rain increasing but by no means certain
