Enjoyed watching Tom Schaf's weather for the week ahead on the BBC.

He was forecasting so well until the very last sentence at the end "Things may settle down...Just for a short while!"

Anyone else catch this?

UK Outlook for Thursday 6 Dec 2018 to Saturday 15 Dec 2018:

Thursday should get off to a clear start with widespread frost. It is then expected to turn cloudy, wet and windy from the west later with some snow likely over northern mountains. The rain should clear through Friday with blustery showers following and winds staying strong. It will become milder but may not feel it in the wind and rain. The weekend is then likely to be unsettled with some gales. The heaviest rain should be across western and southwestern upslopes and the heaviest showers in the north and west. Things should start to turn drier and colder during the following week. There will likely be bands of rain with hill snow in the north, these interspersed with drier and clearer, but at times showery conditions.

UK Outlook for Sunday 16 Dec 2018 to Sunday 30 Dec 2018:

As we head through the second half of December there are signs that there will be more frequent periods of dry and colder weather. However, occasional bursts of unsettled and milder weather are likely, with the potential for some windy or even stormy spells as well.

The second half of that forecast shows how the models must be all over the place at the moment! I think every base is covered just in case.
Tough work forecasting at the moment- flip flopping around.

Would they not be better off going "we dunno!?". It would be interesting to take their lrf for the first of each month and see how it actually panned out...

PS "This will bring heavy rain and gales or severe gales, with a chance that it may even turn stormy at times"... isn't heavy rain with severe gales pretty much the definition of stormy anyways?

I think the MetO's description is fair, given that classification of wind divides into Gales, Strong (Severe) Gales, and Storm force.

Yes, as far as I know the Met Office will only use the word stormy in association with storm force winds rather than named storms.

UK Outlook for Friday 7 Dec 2018 to Sunday 16 Dec 2018:

Friday is set to be wet and very windy in the north with severe gales on coasts and hills. The rest of the UK is likely to have a windy day too, though with less disruptive winds and lower rainfall totals. The weekend is likely to be unsettled too, alternating between sunshine and showers. By the end of the weekend, thicker cloud and rain are likely to move from west to east. The heaviest rain may well be across the north and west. The weather will tend to turn drier and colder during the following week with lighter winds. Lower temperatures and longer dry spells will mean that night frost and fog become more likely.

A big contradiction come on ahaha! are they that clueless? There are two extremes there!? Very stormy, windy and milder is the exact opposite of drier and colder. ..!?


So in other words either cold and dry or stormy and milder?If so then at least it won't be a boring weather wise - i.e 12 or +13c by day and night with overcast cloudy skies, dull days with drizzle and/or light rain etc,

It seems quite clear that the most probable outcome in that time period is an increase in the colder more settled spells interspersed with briefer (much) more unsettled spells? Or a more I reading that wrong?

It’s not contradictory and just states that’s the prevalence of one type of weather will increase yet there will still be briefer bouts of a very different type.

Yes high pressure building but vigorous Atlantic systems briefly during a 2 week period, an unlikely scenario because if you have the latter it's usually associated with a progressive zonal train.


 


From December 27th 2020, zonality will be banned from mixing with the UK. We appreciate that this may come as a shock to younger people and old Uncle Barty. This ban will last for a minimum of ten days.

They've certainly gone downhill during the last year or two and  I've no inclination as to why as they use to be really well presented.

Update to the longer range text forecast

UK Outlook for Monday 17 Dec 2018 to Monday 31 Dec 2018:

For the middle part of December there are signs that there will be more frequent periods of dry and colder weather, bringing a greater chance of overnight frost and fog. However, for the weeks immediately before and after Christmas, wetter and milder weather will become more likely, with the potential for some windy or even stormy spells, and above average temperatures. Any snow associated with these wet spells is likely to be confined to hills in the north.

So the before earlier today you posted: - 


"As we head through the second half of December there are signs that there will be more frequent periods of dry and colder weather."


.............is not the case now?  Also 17th December - 31 December falls within the weeks immediately before and after Christmas...? They mention for the middle part of December it will be drier and colder but the middle is on 15th and this forecast is from 17th??


haha - just wait until we see some cracking GFS models soon and then the Met Office will flip back to cold again.

Seems to be a high level of confidence of some colder and drier weather around mid-month but weather online keeps this HP going! They have early December right so far.


Not many people talk much about Simon Keeling on here, SO i assume he is not as popular or a well known forecaster!?

Duty forecaster: Simon Keeling


Frost and fog, more unsettled later in the month

Higher pressure is expected build during the month increasing the risk of fog and frost as well as dry weather. The Christmas period may become more unsettled with rain and strong winds. Perhaps becoming colder too.

*26/11/18 - 3/12/18*
Deteriorating conditions. Wind and rain to the west, spreading east. Becoming milder

*4/12/18 - 10/12/18*
Unsettled start with rain. Improving through the week.

*11/12/18 - 17/12/18*
Higher pressure brings fog and frost risk again. Dry for many.

*18/12/18 - 24/12/18*
Pressure stays high with fog and frost risk overnight. Dry for many. Need t watch for change in northern Scotland later.

*25/11/18 - 1/12/18*
May become unsettled and colder from the north. Rik of gales and some wintry conditions.

BBC monthly outlook


Summary


Unsettled and mild weather to come



Monday 3 December—Sunday 9 December


Wet and breezy but often mild in the south.


Cloudy at times with showers and some longer outbreaks of rain. Monday is expected to have a mixture of bright spells and banks of cloud with showers in places. There is a risk of some heavy showers over southern areas of Britain while northern Scotland will have a risk of more prolonged rain and upland snow in the morning.


After a chilly but bright start for many, Tuesday is expected to see rain and brisk winds spreading north-eastwards through the day and into the night with a risk of hill snow for a time over northern England and in Scotland.


The remainder of this week is likely to see changeable conditions with further rain spreading from the west at times. The south looks set to be mild. However, there are chances of somewhat brighter but chillier conditions spreading from the north-west next weekend.




Monday 10 December—Sunday 16 December


Very wet at times but generally mild.


In the second full week of December, we are likely to see a return of rain and brisk winds as low pressure areas re-emerge from the Atlantic. Generally, a lot of cloud is likely at times with outbreaks of rain spreading from west to east across the UK. Temperatures are expected to be mostly above the seasonal average. However, Scotland could be cold enough at times for some occasional snow mixed-in over hills. Indications are for wettest conditions to be over western areas of the UK, where high rainfall totals could produce local flooding. It is also likely to be windy at times, particularly over western areas of the UK.

There appears to be only a slight risk of colder easterly winds developing for a time around the middle of the week. Most likely, though, is for a generally mild, wet and breezy pattern.




Monday 17 December—Sunday 30 December


Wet, windy and mild.


Indications are that the second half of the month will be characterised by wet, windy and mild conditions with a strong jet stream moving in from the Atlantic at times. The jet stream is a ribbon of strong winds in the upper atmosphere which helps to drive in weather systems that bring wet and windy conditions to the UK. Western areas of the UK are expected to see the most rain. There are indications that rainfall could be well-above normal for December, bringing a risk of flooding.


Strong winds appear likely at times, perhaps most likely towards the end of the month. However, the positioning of the jet stream will dictate where the wettest conditions will be. There are chances that the jet stream lifts northwards for a time before Christmas to bring a brief drier period of weather to southern areas. After Christmas, there appears to be some risk that the jet stream drifts further south, bringing a risk of colder conditions into northern parts of the UK.


Anyone hoping for a white Christmas could end up being disappointed. However, it is still far too early to say for certain what weather we will have on 25th December. Even in some of the mild Decembers of the past few decades, short-lived cold spells did crop up and even produced short spells of snow. A green Christmas is not guaranteed...yet.




Next Update


We will take another look at the month ahead to see if we are still on track for a mostly wet, windy and mild December.
