A really blustery day here, now abated.  Barely any of the showers reached this far.  And now the temp's dropping away again.

  Glen Orrin yesterday. Blustery showers, wintry down to low levels, although the snow was melting - and filling the burns!

Minus 6 yesterday morning then a glorious day until heavy showers late afternoon, very icy this morning with loads black ice but sunny skies although clouds gathering to the west heralding the coming change   Good covering of snow on higher hills prob above 2000 ft

Your powers of observation must be failing you as apparently winter is over!

3rd consecutive air frost last night, fine by day, odd little bits of wintry ppn occasionally. Ground still very wet - and cold too now, so not really drying much in the still air.

[Scottish weather discussion - Spring 2023/24]

Moderate sleet on now at 2C. Gentle westerly breeze.

'Well that didn't last long!' exclaimed the actress to the bishop. 'By the time I looked up, it was all over!' ('and look at the state of your cassock...')

There's a patch of grass near home that I cut across several times a week and I've never know it so continuously sodden. It's not at the mudbath stage but on its way.

Also there's not been enough dry days together for it to be worth giving fruit trees the oily wash for greenfly this winter. Normally I'd be doing the 2nd about now. Not a good prospect for the trees,

Misty, drizzly, still, damp, cool, gloomy and dreich.

[Scottish weather discussion - Spring 2023/24]

The weather continues to ming this morning. Absolutely rancid. You'd think a 'warm sector' could provide something better than this!!

[Scottish weather discussion - Spring 2023/24]

The day started frosty and clear but went through dreich into minging by teatime.  

@TillyS Ben Wyvis dominates the northern views from around here - for locals, that view is kind of burnt into your visual memory!  It used to be white fairly reliably from October to March but not any more.

Another frost last night at -2C. No noticeable wind just now.

Another cold day with a fresh west wind ground frost in the morning which lay all day .in the shade. Ground has lost of surface water. Currently 3c.

Pretty much the same here for the day, some good sunshine too.  The frost lifted completely here in the wind.

I'm seeing signs of a cool down later next week perhaps?

Additional to the above post, what happens to the polar vortex if the Amoc collapses? Does it expand south to lower levels in the hemisphere or stay roughly where it is? Or is it governed by other influences.

My really overly simple thoughts are that if the Atlantic slows down, we'll get progressively drier as well as colder, but you'd think there'd be a massive shake-up of how the atmosphere turns over in both hemispheres.

[Scottish weather discussion - Spring 2023/24]

Well the wind has gone at last.  Now we're smothered in haar at 1C.

Of course. That's what research is about. Why would you publish just already known facts?

 Looks rather more than 'a bit colder' to me! A very short grass-growing season would be one impact. Many crops would be gone unless grown under cover, like Iceland. 

Yes, this is all hypothetical. But it's within the bounds of what's possible, and our resilience to this sort of climate change is limited.

[Scottish weather discussion - Spring 2023/24]

Not quite such a strong wind today but it's a crappy day all the same. A sanding skirting boards type of day!

That doesn't make happy reading.

[Scottish weather discussion - Spring 2023/24]

All our lying snow has now gone. The last bits vanished really quickly and without melting, just disappeared into the air. 

<snow fetish alert> It was fascinating watching the snow ablate - it didn't melt into blobby lumps, it held its crystal structure all the time, just shrinking away. I don't see this often just here.

1C and dry for now. Typical miserable grey straight easterly day with the heat being sucked out of the house.

The thermometer is sat exactly at 0C but with a stiff easterly, it feels Baltic. Yesterday morning's snow is still sat defiantly on cold surfaces out of direct sun but I think will rapidly ablate in this wind.

 

[Scottish weather discussion - Spring 2023/24]

My 2 pennyworth on forecasting the likelihood of snow soon... I watched the MetO so-called 'deep dive' the other day for some insight  I won't be wasting my time on that again as the only measure the guy seemed to put any emphasis on was the height of the 0C isotherm. Talk about dumbing it down.
