1489ft seems to be the highest point in Nenthead - 454 metres is the highest point I could find with the lowest point being around 425. Yep, that's high! -

Once all this Covid malarkey passes I hope to explore more of the Highlands and Newtonmore will be on the list. -

Unfortunately, that claimed altitude was shot down quite a while back - I remember reading about it after there was a dispute between Wanlockhead and Flash in Staffordshire about the highest village in the UK. Highest village claims were no Flash in the pan - MacclesField Express WWW.MACCLESFIELD-LIVE.CO.UK NEWS Flash - the highest village on our patch is now officially the most lofty settlement in Britain. Where is Scotland’s highest village? WWW.BBC.CO.UK Two villages in the southern uplands both claim to be the highest in the country. You can get pretty accurate altitude readings here - Elevation Finder WWW.FREEMAPTOOLS.COM Find an estimate for the elevation of a point on the earth just type in the place name. A quick look confirms Wanlockhead maxes out just over 440m. -

Corgarff is nearer 400m and c0ck Bridge (is it even a hamlet?) is 410m. Wanlockhead is around 430m. -

Spot on sir! Yes, for mean elevation, Dalwhinnie is the highest. It doesn't fall below 350 metres above sea level and maxes out at 360 metres. Tomintoul isn't any higher than Braemar despite some outdated info you'll read on websites about it being the highest village in the Highlands. Braemar maxes out at 370 metres on Chapel Brae. Tomintoul maxes out at just over 350 metres. For mean altitude, I think Braemar pips Tomintoul although it's a bit tricky to compare these two for mean altitude due to the fact that they're 10 times the size of Dalwhinnie and there's much more area to cover. -

I love how easy it is these days to find out your altitude using the elevation finder. It's fairly accurate too. I've passed the time lately using it to explore the elevation of Highland villages like Braemar, Tomintoul, Newtonmore, Aviemore etc. It's led to someone interesting findings about the highest village -
Model output discussion - deep cold inbound?
Sawel replied to Paul's topic in Forecast Model Discussion
GFS 12z Parallel on Meteociel - very similar to all other output from 96hrs to 168 and then there's an attempted breakdown of sorts. -

Meant to reply to this yesterday but didn't have time! With everyone getting in an 'easterly mood' then here we go... I've spent a lot of time (too much, but thanks lockdown) looking through archived charts of historic UK cold spells. Archived charts on Wetterzentrale are better for a few reasons but mainly because you can view archived charts in 6 hour increments. On Meteociel, they're done in 12 hour increments so you can miss extreme charts. Plus the resolution is quite poor. According to these charts -20c uppers have hit the extreme SE of England during the 1987 easterly. The 12th of January being that special day. The 1987 easterly is unrivalled for two reasons - Firstly, the sheer depth of the cold across the entire UK with the -20c line apparently making it to our shores. But what is also staggering is that -18c is covering much of England and Scotland and even reaches the middle of Ireland! -16c has even managed to go beyond the west coast of Ireland and well beyond into the Atlantic ocean. For such brutally cold uppers to move that far west really highlights the severity of the 1987 easterly cold spell. Staggering! 12th January 1987 - 0z, 12z and 18z below. These are the coldest charts that exist for our shores.

I got the joke and it's the best chuckle I've had on here in a while! -

February and March 2018 was exceptional but uppers maxed out around -17c. February 1991 was exceptional too and Uppers seem to have maxed out just short of -20c. -

A scan of the archives (since WW2) focusing on the most severe easterly outbreaks the UK has experienced would suggest that the -20c uppers may have clipped the extreme SE of England in February 1956 and/or January 1987. These two cold spells had the deepest cold pools. It's impossible to tell for sure from these charts if the -20c did hit our shores but we can say that at the very least, we have come extremely close. 1956 and 1987 charts... -

Some pics sent from my mum - 7 miles ENE of Strabane (North Tyrone), very nice covering and snowing away.

According to the ECM, Dundee has changed its name to "Kozaksville". How peculiar.

Model output discussion - 7th January onwards
Sawel replied to Paul's topic in Forecast Model Discussion
Their app doesn't use the UKMO raw output, they have a high res model which is used for the forecast (symbols) on their app and website. After 72 hours it's the MOGREPS mean.
