How come low pressure easily pushes away high pressure? it's how it seems
At which point in the current outputs are you seeing this ? GFS 06z has high pressure pretty much in control from T96 out to T192. ECM has it in control from T96 right out to the end of the run. If you're concerned about what GFS 06z is showing at T204 onwards I have a simple suggestion. Ignore it, it'll change.
This is arguably the best spell of settled weather we've seen modelled during UK summer output for 5-6 years, and much the same as when we get excellent cold charts modelled in winter, there is always some conjecture about the 'breakdown', even when it's in far distant FI.
To be honest I'd rather concentrate on the T48-T102 timeframe as this is where we need to see the current modelling maintained, because whilst current output looks favourable for an extended period of settled weather, the fact it's still 4 days away, and the other side of a more active Atlantic period, means there could yet be some significant changes to what happens after the rest of this week.

I guess those that are smelling 'conspiracy' are conveniently ignoring BFTV's post ? The difference with this particular meeting is that for some reason the media have picked up on it, not that it's an unprecedented 'warmists are alarmed' special conference..........
Slow news day maybe ? Personally I don't see anything wrong with a group of experts in their field coming together to discuss an issue of particular pertinence to their chosen discipline ?

You seriously believe that the 'green agenda' holds more sway in the Western corridors of power than the lobbying/vested interests of the global carbon multi-nationals ? You truly believe that governments have some kind of conspiratorial agenda to foist 'green taxes' on us rather than be swayed by the interests of some of the most powerful and economically important corporations on the planet ? Please point me to single scrap of verifiable evidence that this has happened or is happening. It would be nothing short of a policy making miracle..............Lol, the evidence is only overwhelming if your closed minded. This evidence you speak off relies on far too much conjecture which makes it no more overwhelming than any other theory, except for the fact that scientists in general rely far too much on government monies so the urge to find other causes is, shall we say, non existent.

Great minds think alike 4wd !!! As it was 1st May I thought I'd snap the last remaining bit on Holme Moss. I think this is by far the latest I've seen any snow on Holme Moss, (mind you I've only been here since 2000). Quite surprising as it's not even 2000 ft high, .

I've shortened the post. I think cloud cover plays a significant roll in the solar effects, i had read that reflecting sunlight from cloud upwards and reflecting sunlight from snow cover effects the NAO(north Atlantic oscillation) affecting blocking which in turn alters the Jet stream, which in recent years has shifted south, making it colder here. The little ice age had such a significant plunge in temperatures that even summer stayed at or below 10C(50f) throughout! UK. I do have concern that this could be happening. but we would have still a hot feeling sunshine even if the upper temps are cold for summer and the surface temps are cold.
NAO is not an entity in itself which drives weather, it is the expression of pressure differentials in the North Atlantic. If average pressure in the North Atlantic is projected to be above average then this will result in a negative NAO, and if pressure is lower than average then conversely NAO will be positive. It is incorrect to state that NAO can cause any particular weather pattern, all NAO is is a way of categorising pressure differentials.
Also, re. snow cover, (I assume you are talking about the Arctic in the context of your overall post), there is little doubt that average annual snow cover in the Arctic is at it's lowest for hundreds of years, so if the albedo effect is to be taken into consideration, it can only be in that it's effect is lower now than for a long long time.
If anything, the most likely reason for any jet stream positional changes recently is going to be because of a warmer Arctic in relation to mid-temperate regions - the reduction in temperature differentials between polar air to the north and mid-temperate air to the south it appears is causing the jet to become more amplified, and because of this amplification different areas of mid-northern latitudes can find themselves on the northern side of the polar jet for longer periods.
So if it is true, (and the jury's definitely very much still out on this), that the weather appears to be cooler for longer in our little bit of the globe it's in fact more likely to be because of temperature rises to our North rather than any onset of a new mini ice age.

Still one or two small patches visible on Holme Moss, might try and get out and about tomorrow, see just how much there really is.
-
Could be quite a wild night, gusts already topping 60 mph, and it's not supposed to reach the strongest winds for another six or seven hours.

Very windy this morning, gusting to 62 mph according to my weatherstation. Feeling incredibly mild though, quite a shock to the system ! Still the remnants of the biggest drift in the sheltered part of our garden - to have a snowdrift last three weeks at this time of year I would think must be pretty exceptional.
-
Lovely weekend. Occasional piles of snow/ drifts left. Bet still some massive ones over Pennines!! Anyone.
Aye, went for a walk yesterday evening, still some big drifts and some reasonable sized areas of cover. If you happen to be travelling along the M62 between J23 and Scammonden dam you can still see some of them up on the hill above you, especially in a hollow just below the quarry stone which sits on the top of the hill, I reckon that hollow must still have 8-10 foot drifts collected in it.
-
Agreed, I'd go with 2002 and 2011 from more recent memory. I'm pretty certain there were some fairly nondescript years in the '70s, but my memory isn't good enough to pinpoint specifics.

Finally found my ten foot drifts whilst out with the kids last Saturday:
I doubt much will have melted even now. We've still got 2-3 foot drifts in the back garden.
-
Any local snow depth/road conditions around the Holmfirth/Huddersfield area today would be appreciated.Thinking of going walking around that area on Sunday.
Most roads have now been cleared so are at least passable if still down to one lane in places, although I believe some of the highest routes are still blocked, (Holmfirth-Woodhead over Holme Moss for example). Some side roads and minor lanes are still blocked with 4-6 ft drifts though, (like the one I live on). And where the snow has been cleared there are some huge piles of the stuff, (reminds me a bit of when I lived in mid-Wales in 1982 though not quite on the same scale). I don't think you'll have any problems getting about though, and I'd say it's well worth a day trip !
-
Went for a wander around the local area today, took some snaps of the current conditions:
I think I chose a good time to have a week off work !
-
The current synoptics seem to be on the edge of uncharted territory compared to recent decades and it makes you wonder what else might be in store.

This must be one of the most prolonged 'showers' I've experienced for a long time, been snowing heavily for at least 45 mins and still hammering down. Covered all surfaces that were previously clear, (not that there were many of them). This really is turning into a quite amazing spell of weather (especially given the time of year).
-
Just been out for a drive locally with the camera. It's hard to get a decent picture, but the two below aren't too bad.
First is the A640 main Huddersfield to Rochdale road, down to single file in many places past Outlane, and still blocked over the top. This is just after the M62 bridge between Outland and Pole Moor:
And this is the Pole Moor to Slaithwaite road, blocked after about 200 yards off the A640:
Apologies for the wet windscreen in the second one, it started snowing again and I didn't want the wipers getting in the way !
-
Been snowing on and off all morning, sometimes heavy (like now). Quite nice really as all the brown, dirty snow cleared and dug off paths and roads is now covered over with a fresh layer so everything looking nice and pristine and white again. And the slight rise in temps is evidenced by the fact that we're getting big fluffy flakes, (although my weather station insists it's -1.8c, which I find rather hard to believe).
-
Latest weather leeds maxes out at 2c. Is this a joke? It's already like 3/4c in leeds as its nearly 2c here at 150m
And just to really cheer you up it's -0.4c here at present
-
Absolutely no thaw as yet, my weather station showing a temp of -1.6c but I think that might be a bit low as I'm sure the wind, which is gusting to 45 mph, is affecting the reading. Just been out for a short walk and it is actually painful, the blowing snow hits your face like a hundred tiny needles. And the drifts continue to grow, or to return when they have been cleared, so I might not be able to get the car up our lane for a few days yet.
-
Took a few more vids, here's one, they're all on the same YouTube channel.
That one's on the main road over the top between Outlane and Golcar (for those that know).
-
Perhaps a bit over-simplistic (I'm not a climate scientist after all !), but of the basic theories I've seen, a significant shift south of the jet stream caused by a reduction in the temperature difference between the polar air mass and mid-latitude air masses, (I believe the Arctic has warmed more than mid-latitude regions over the past 30 years ?). is going to have a big impact on mid-latitude weather patterns. Maybe not an ice age, but for the UK anyway, weather more usually associated with the GIN corridor is affecting us more regularly.
-
Been for my first wander of the day. Put some pics in this gallery:
-
I can confirm we have some snow here. I shall try and get out and about shortly but it's still pretty grim out there. Took a quick vid after helping dig a Transit out of a drift near our house:
-
PTFD, Ten foot drifts this weekend? we are at 5ft.
I very much doubt it, but if it does keep all night (and I have my doubts but you never know) then there could be some nice 'big 'uns' tomorrow morning.

GW, until there is a drastic change in the global economic system short termism will continue to prevail. There is absolutely no chance of a measured and considered response to any possible future threats facing mankind as long as the accepted mantra is one of perpetual growth. Any system where a company making a $5bn profit the year after posting a $5.5bn profit is considered to be failing, or where an investment banker earns 100 times more than a nurse or a teacher, cannot address long term global problems in any coherent way. It's about core values - when those are wrong then everything that stems from them will be wrong as well.
