Better late than never - the MetO warning has been updated today to include mention of the winds.

It will also become windy with gusts of 45-50 mph inland and as high as 60 mph on some southern coasts.

It is interesting to watch the battle between the high over Scandinavia and the lows in the Atlantic later next week.

We see, on its migration, the high settle over the UK early next week with a gradual mixing out of the polar air that brings the chill this weekend. Lovely and seasonal for autumn though with good visibility I'd expect.

I note the UKMO this evening which has a more prominent push of milder uppers across the UK by midweek, and less settled weather attempting to make inroads from the west. Mild southerlies for all of us as the topsy-turvy month develops.

The GFS by contrast holds the warmer airmass to the west. Still fairly mild you'd expect but more of the UK, especially away from the southwest, likely to be dry with some sunshine. Thereafter the colder airmass to the east does make some progress westwards and equates to another chilly weekend. Plenty of interest!

I see that from wanting to stay very cool yesterday, the GFS Ops run this morning has flipped to the top end of the 850 hPa Ens range and is now looking very mild in about 6 days time.

Has GFS Ops always been this bipolar? It seems to have been much less 'average' recently.

GFS goes rather chilly again for next weekend.

I'm off to France during half term week and GFS looks exceptionally wet for that week at the moment!

WX for week1 show temps below average for Baltic area, and esp for Norway, a little above for the rest of W Europe. In week 2 not much change for W Europe but a large freezing area developed over N Scandinavia and N Russia, the latter having previously been quite warm for the time of year.

GFS Op  - current HP being slowly displaced by Deep LP off Iberia which arrives here on Wed 16th (enjoy the warm SE-lies while they last!) and settles down by Sat 21st 985mb N England with trough linking to Greenland one way and the Alps the other way. LP persists near Britain with intensification 980mb N Sea Fri 27th and 975mb St Kilda Tue 31st.

ECM - similar pattern though LP holds off to the W Wed 16th but same by Sat 21st and an extra LP 980mb Scotland Wed 23rd

GEFS - countrywide, becoming warm for a few days around Fri 18th with rain setting in about then heavy for a few days and then persisting, temps close to norm.

Sorry I will keep slating at the models until they accurately show what it willl happen for the next week.  Was showing a dry week with temps rising back to average to now very wet week.

Forecasts change, and realistically given the multitude of factors and data involved, will continue to change between model runs for the foreseeable future. If they didn’t change in the past it’s because there was less data and, as very clearly documented research has shown (and been shared with you before), models were significantly less accurate in the past. As the saying goes you’re entitled to your own opinion but not your own facts. 

I have shared the research data showing the improvement in model and forecast accuracy over the years with you in the last few months, if you have evidence to the contrary beyond your own opinion please share them with us all.

Unfortunately more flooding looks likely later in the week for this region with a Sever weather warning in place for rainfall from Thursday to Saturday. Given the timescale involved there must be a level of concern about the impact (and given the models I’m not surprised). Still time for it to change but I doubt if it will alter significantly from the overall current picture.

It reminds me of October 1986. It was generally quiet, dry and settled for first 17 days with abundant sunshine, and mostly quite warm, in fact very warm on 1st with max temperatures exceeding 22 C in Lincoln where I was living. 

However, for last 14 days, it turned very unsettled and wet, often windy, and on some days notably cold; it was only 9 C in Lincoln according to my thermometer on 22nd. The current model output (released on 15 Oct) resembles that of 2nd part of October 1986.

WX temps show most of Europe N of the Alps as cooler than average in week 1, only the Balkans are noticeably warmer. Not much change for week 2; perhaps a little warmer for continental Europe, cooler in N Russia though this downplayed since yesterday. Some rain for much of Europe in week 1, heaviest in the west and over the Alps (early snowfall at high levels?) . In week 2 the focus shifts to the western edge of the continent especially France. Britain averagely wet both weeks

GFS Op - LP moving N from Portugal to SW Ireland 975mb Thu 19th, with S-ly gales for a while, changing direction and becoming 980mb C France Sat 21st with strong E-lies for Britain. Then a series of Atlantic LPs moving E or SE-wards with no intervening HP; 960mb Fair Isle Wed 25th, 975mb N Ireland Sun 29th, 980mb Biscay Wed 1st. Any Hp in week 1 near N Norway and in week 2 near S Russia.

ECM - differs from GFS in not sending the LP to C France; instead it sticks over S England 985mb Sat 21st. The later LPs are closer to W Britain; a secondary LP SW Ireland Wed 25th and the one over Fair Isle moving SE into Scotland Thu 26th.

GEFS - becoming mild for this week, then mean mostly a couple of degrees below norm (op & control generally cooler around Sat 21st, and Scotland definitely cooler at this time), rain setting in Wed 19th and continuing for the forecast period, often heavy
