Snow was forecast for Ben Nevis during Hector. I recall in about 1987 or so when during an August depression with high winds it was snowing at 2500 ft...

Please can you shift it 50 miles North? Ta!

Indeed so the methods could be precisely accurate or imprecisely accurate or precisely inaccurate or imprecisely inaccurate. Hence as BFTV mentions above consistency of methodology is key. Once there is enough data from new methodologies, comparison, correlation and extrapolation can be made, but with the caveats re precision and accuracy being important. It's a bold move to bin an entire dataset due to a new way of testing / evaluating. If we look at sun spot No's, we know there were inaccuracies in the data, but the "new improved" data hasn't just trashed the data from e.g. the maunder minimum, because there has (I believe) been a correlation exercise which takes the limited equipment etc into account. Maybe something similar could be achieved with ice extent, thickness and age by running methods alongside for sufficiently long to be meaningful.

I'm not an expert on ice, I'm not an expert on data, in fact I'm an expert on very little, except putting my foot in it! That said, I am reasonably experienced in pragmatic use of information. If systems and measurement techniques have evolved to be more accurate, or are they more precise?( the two are not the same, data can be more precise but no more accurate) then you have to use the old data alongside and use the new data to create a correlation and backwards extrapolate for any of the data to provide meaningful continuity and comparison. Don't you?

I hope that verifies, looking at a water shortage hereabouts if not, maybe even with the 2" of rain suggested.

Except unwell?

It's a grey start here with mizzle....underwhelming....

Aye, I'm still a lancastrian by birth, complete with LA21 postcode!

Thanks...ever hopeful of seeing something of that ilk in my lifetime...if I recall correctly Mr St Helens famous eruption in 1980 did have some impact..(?)

Fair enough, just a thought!

What a refreshing change, the North West being favoured with the pick of the weather! Models as far as I can read them suggest below average ppn, we'll be talking hose pipe bans before you can utter the word "drought"!

Maybe too early to tell, but is there any scope for the Kilauea eruption to affect short-medium term weather locally and /or globally?

14.8 C and 58mm please

Aye but a grand morning for a plod out!!

I know the route well Moki! Which pub did you patronise and what was your tipple? Assume you went up the old man via low water?

Driech....has been since about 13:00...waste of a day...

I was on the fells yesterday and was surprised how clear the air was then! From Silver Howe near Grasmere we could easily see the summit of Ingleborough maybe 30 miles away as the crowd flies, could be more...

They're called Avios points now I think....I thought that was Spanish for "do one"

Nah, sounded very cathartic!

Might be another dollop to come Moki, depends if it cools down too much I guess

Yeah was an absolutely beautiful day to be on the tops, very mid summerish, but with a different more genial, less harsh midday sun. Didn't prevent Mrs C getting a touch more colour than desired but hey, better than the mildewfest we'd otherwise have! Managed the first bbq of the year, utterly sublime as the midges aren't in full flow yet! I think we got your rain as it suckered down, my daughter was at ours when it started had to dash home to get washing in. She's back here now borrowing the the tumble dryer!

Aye, still rattling a bit, odd flash...lightning as well

We're having a goodly storm atm, biggest claps of thunder I've years in years!!

12.2C and 70 mm please
