Great Britain..

Anyway, looking at radar it is mostly snowing on hills so do be realistic when you are saying snow. It is now raining in the centre of Glasgow.

And my sis lives in Aberdeen and says it’s raining there. Shall we extrapolate that out to the whole area too then?

I don’t need to be specific. Don’t say it’s snowing all over the place when it’s mostly on the hills.

To be fair,it is marginal but is snowing in some large urban areas in southern central Scotland and Northern England
Here's a selection of webcams in Leeds Bradford, Sheffield amongst others

See that's when your caught talking bollocks sir

Most of the folk showing these pictures arent living in any hilly regions, areas of Glasgow,Penilee, Hillington Cardonald, those 3 for example are anything but near hills

Lanarkshire, Fife etc again arent notorious hilly places,see, if your going to post something at least get the facts correct instead of reading it off netweather

Finally, some blue skies are appearing in wexford, probably won't last long though.

Looking at Netweather radar, to me it looks like the vast majority of Scotland (and most of north England) is experiencing snow rather than rain. I just had a look at a webcam on George Square in the middle of Glasgow city and there's a slight covering in the grassy areas. As George Square is pretty much at sea level and in the middle of highly urban area, it would be reasonable to assume that the snow is not mainly on the hills.

Aberdeen and the rest of the east coast of Scotland is under the influence of an onshore breeze resulting in higher temperatures than most of Scotland and consequently is one of the few areas that is experiencing rain rather than snow.

I get there maybe some tension with the flip flop of the charts , and rite now we sit with the flop in hand , but please keep it civil and stop trying to pick arguments

If there's nothing by then more than normal short bursts of westerly Atlantic Hill slop in the outlook I'll be calling this a scamstrat as it will have had its 2 weeks plus and done nothing for Ireland anyway and won't want to hear anything about Stratospheric warming nonsense ever again

If you feel that way then fair enough. However, I will continue to post about the stratosphere ‘til the end of time or as long as I’m a weather enthusiast anyway as I find its variability and dynamic nature quite interesting irregardless of what happens at a tropospheric level. How it can vary from a very strong SPV to a very weak SPV in a matter of days via stratospheric warmings. It’s just all fascinating to me. It’s a continuously researched phenomena too so there’s always something new to learn and nothing is concrete. The stratosphere never “promised” anything, I think it’s people’s expectations getting the best of them (and I have done that before too *sigh*).

It’s unfortunate it is now used as another source that the media can “justify” their nonsense on that they pull out of their arse because of events like 2018. I do find that quite frustrating knowing that was the extreme end of tropospheric impacts and will highly unlikely see again anytime soon.

To be brutally honest,I've as much interest in the North Pole strat as I do in the Mars strat if it doesn't affect our weather
But I do read your interesting summaries of what's going on up there vs delving in myself
I do so I think with enough understanding to judge if there's going to be any impact down here
I still expect there will be,but am not interested in another week of time wasting flip flopping output watching ,I want the 2 to 3 weeks post major strat warm to play out to its bitter conclusion at this stage as my confidence of a response that affects us is low
So please don't take my views as a disrespect for your strat watch
Its very helpful

Finally the sun, I've missed the sun. Can January end now please? :pac:

For real though, I am very much enjoying the milder weather with sun for once. We had a great cold spell but it didn't deliver what we all wanted, so I'm happy to roll on the warmer summer/spring days now.

Yep all your fault. May you never see snow for a decade.

Gaoth Laidir · 14-01-2021 12:56pm

Cracking heavy snow sounding from the 06Z radiosonde from Albermarle (144 m amsl), up near Sunderland. A deep, almost isothermal, saturated layer up to near 650 hPa means there's a lot of moisture to form flakes and hence heavy intensity. Down at the surface temperature and dewpoint both 0.2 C, so big dinnerplates were probably falling at the time. Continuous moderate snow, with visiblility below 1 km, was reported there all morning. Latest report has 9 cm lying on the ground.

Not quite a weekend but it was the beginning of the working week. It was fantabulous, late February 2019 before a very wet first half to March. Several stations achieved their highest February temperature on record but we fell short of the national record (18.1C). Was unusual seeing such beautiful sunshine whilst so mild in winter time, usually it's cloudy and damp if very mild.

I get blasphemy for loving that period but it really was so lovely. My winter mood has well passed by that point and I long for any kind of warmth although I take sunshine all year round.

Obvious Desperate Breakfasts · 14-01-2021 1:16pm

Weather/geography heads - do you think this is possible? I’m dubious. I think the distance is too far. I grew up a third of the distance from a mountain 200m lower than Snowdon and we could see it from our house (approximately the same in size and clarity as Snowdon appears in that photo) but it’s hard to imagine seeing it at even twice the distance away. Actually, no, I’ve checked. You can see the mountain from Galway city over double the distance to the mountain from where I grew up You could just about spot it on the outskirts of the city. Snowdon is over three times the distance from Dublin than I was from that mountain. But some kind of telephoto lens was used apparently?

I think that photo is enhanced. But yes if you go from sea level to altitude you can see a lot further.

Sometimes locally (depending on the weather) if you drive from 200 metres down to sea level on my north coast, you can see Islay disappearing from view.

highdef · 14-01-2021 1:42pm

It's absolutely possible and I would not for one moment doubt its authenticity. Photographer claims that the photo was taken at Howth Summit. This is around 170m. I've seen those mountains from a high vantage point in Howth, the summit car park (which is not actually at the summit) for example. The air was exceptionally clear the day the photo was taken. That, combined with high reflectivity of the snow combined with the resulting higher than normal contrast between the snow, the sea and sky plus the use of a telephoto lens and/or cropping all lead to this pretty spectacular photo.

Gaoth Laidir · 14-01-2021 1:46pm

No problem seeing it from up on Howth Head. It doesn't seem to be enhanced, just the parallax from a zoom lens. The top of Snowdonia peak is the same height as Carrauntoohil, so at 140 km away it's not difficult to see it from 100 metres up.

Yes it is possible. You can also see the Mourne Mountains from Dublin which isn't much different. Get yourself a good zoom lens and a camera and you would be surprised how far you can see. I have seen images from Wales looking across Ireland and its mountains.

I studied the photo further. The red brick houses in the foreground are located on the right hand side of the road leading up to "The Summit Car Park" @ about 140m ASL. Going by the angle of the photo and the apparent height above the houses, I have surmised that the photo was taken from the Ben of Howth ( https://goo.gl/maps/9eNGb8LAr39BBBAA6 ) at about 160m so that just further goes in the favour of this photo being genuine, not that I ever thought otherwise.

Cleared up to be a nice sunny day in wexford. 11'c currently according to thermometer outside, it's almost like summertime out there. This is the mild weather I like, not the usual wet cr-p.

Niall145 · 14-01-2021 2:56pm

Hi all,

I am the photographer behind the capture of Snowdon taken from Howth Summit (an avid lurker on this forum too i must admit). It was taken Tuesday afternoon from the Ben of Howth (171m). Was a mostly cloudy day here but with exceptionally clear conditions in the Irish sea (Isle of Man and the Mournes also visible). That combined with the snow still lying on Snowdon definitely helped in getting this shot! It's on my instagram too at ncarroll22 (Niall O'Carroll on FB).

Yeah but I was just genuinely interested. I added in my own experience to explain why I was doubtful but I’m willing to learn. A few people are questioning it on Twitter because, well, Twitter but the reaction seems mostly positive.

If I was the photographer, I wouldn’t be offended by questions. I’d just say what I did to achieve the photo and if people didn’t believe me, let them.

ZeroSum76 · 14-01-2021 3:01pm

Great photo Niall. The following picture was taken by Tommy Dover in Wicklow Town and posted on the Wicklowmaritime Facebook page. It's possible to see Snowdon from Wicklow Town on the odd occasion. It's freaky. It's almost as if a mountain range springs up in the middle of the Irish Sea when it happens.

Even if we dont get any cold and snow at least we are only a couple of weeks away from febuary...we can even get summer temperatures in febuary the record is over 18 degrees...and the March record is even better at 24 degrees...more than what we get most summers

Minimum surface visibilities were reported up to 65 km at 3 pm on Tuesday, which is pretty high, but they were likely higher. Add to that your altitude, which gave you a surface horizon at 47 km, and the altitude of a snow-capped Snowdon (1085 m) beyond that and all the holes in the cheese lined up.

Sometimes when flying I can see the Galway coast from around Enfield in Meath from around 3000 ft (1000 m). There is sometimes a large increase in horizontal visibility when you get a few hundred metres up out of the murk. With a summertime inversion the sudden increase in visibility as you climb up through it can be stunning.

For the record, here are the horizon distances for an observer at different heights. They increase logarithmically with height.

The photo nerd in me is wondering about the lens and focal length?
