Paul Simons in The Times (UK) 20FEB15 mentions fohn again. On 18FEB15 Fyvie Castle, Aberdeenshire, Scotland, soared to 15.6C (60.1F). He said Aberdeenshire can benefit from some warm, sunny conditions as fohn winds sweep down from the Highlands.
As Rare As…
1. We started with ‘… snow in Phoenix, Az’. Now my friend in Dallas, Tx sent me a picture of snow in Dallas yesterday – looked like an inch or two. (Checking my Weather Guide data for March, Dallas has an average snowfall of 0.2″, max 4.3″. For comparison Phoenix, Az. has a Trace and 0.2″. There are several others < Dallas, mostly further South and/or coastal, I would say).
2. ‘… a flying weasel’:
Photographer explains how he got THAT pic of a weasel riding a woodpecker
I actually thought that though off-topic this was an excellent illustration of MikeL’s guideline ‘always have your camera ready’. MikeL emphasises that Cloud Moments can be fleeting (as the red-violet moment in the sunset in the first (and only so far) picture in my Forum Album).
In The Independent Wed 4MAR15 it inspired political cartoonist Dave Brown to a cartoon (which I cant find on-line) entitled ‘The Flying Weasel… Shock Picture’ with the UK Prime Minister as an aghast woodpecker, and upstart Nigel Farage, UKIP, as the weasel (fag but no pint of beer).
Airhead, putting two and two together, we must have enjoyed your wife’s contributions to the old Forum – Alexxx? With the droll profile picture old goggle eyes? Perhaps she will find Bill’s recent posts here of interest.
Regardless, either or both are doubtless enjoying the International Year of Light; light2015.org.uk. This may well interest some on this Forum though as far as I could tell at a quick look there is much astronomy but no cloud (no challenge); not surprising I suppose.
Marsha, by chance I think this TV program which was repeated this evening was what I was referring to. Ice builds up on a lake then slowly but steadily rolls off the lake and into a house. (It’s some way into the program (Series 3, Episode 1) after a break for ads).

This is The Independent’s answer about That Dress:
Two birds with one stone. I seem to remember a similar freezing situation last year, Marsha – fascinating is it not.
Your link also answers the question absorbing BBC Radio this evening – That Dress. I saw blue and black on your link (apparently the correct answer, not white and gold). Which raises the question how do we all see sky colours? One Prof on BBC Radio suggested it might be a similar effect for (some) viewers to looking through say red Perspex – some colours will change.
P.S. I am so envious of that double ‘H’.
Yours, ‘H’
Thanks for that, Airhead (my apologies for my habit of setting challenges for others). It is interesting that you lighted upon RK Pilsbury – I did too, and I have that book but dated 1969 (acquired on the second-hand market). Also, several of those ICA II pictures by RKP were taken on the Isle of Wight within my local region – so I figured there must be something interesting around and joined CAS in 1/07 to find out more.
In the book he mentions two pictures of noctilucent cloud taken by himself at Swansea and his daughter at Bracknell on the night of 27/28 June 1966 which enabled him to calculate that the cloud was 84 km high roughly over Dublin. GP-P checked CAS membership records (after 1/07) and there was no Pilsbury.
‘H’
Graham, I can confirm that the ICA Vol I revised edition 1975 has Sc cas (but floccus was not introduced); possibly not the Vol II 1987, unless Airhead knows better.
All the books I have checked have Sc cas.
The (probably 1982) PDF should have Sc cas in CL 5 around p8 (different on-line)
http://www.metoffice.gov.uk/media/pdf/r/i/Cloud_types_for_observers.pdfThat leaves later on-line Met Office docs meant for the more casual observer – perhaps they are your problem, Graham? I have not checked them.
I only wish I could add my own observations, but I seem to be blind to cas.
‘H’
Oh, well read, Airhead. That’s impressive. I still have to read Colin’s news extra.
For AK: as I must have mentioned in the distant past, page 126 is at Bishop, Ca, ‘Fohn wall, rotor clouds and orographic Altocumulus lenticularis’. We are lucky AK so often records such phenomena in the Owens Valley for CAS.
Change date in topic title?
Gini, it might be an idea as some might just glimpse the title (e.g. in Recent Topics) and not read the detail. I don’t know if you can do that in this forum.

CBS plays catch-up?
No new news, but good publicity for CAS:
http://www.cbsnews.com/news/cloud-gazers-discover-new-cloud/Martin, looks like the American Eagle himself. Deserves the motto Big Sky Country, but I guess neighbouring Montana got there first. Great – thanks.
Colin, the Wiki entry is the only place so far I have seen an average figure for length (which I think I called size) and its 0.5 km. With an average diameter of 1 – 3 km does that make your ship quite far off?
http://en.wikipedia.org/wiki/Mammatus_cloud
(There are several pix at the end of the Wiki).I have not seen any given cause linked to dimensions, and UK skies above are as cold as any, I guess; intensity would be higher on the Great Plains.
Colin, can you add a synoptic situation? If nought else it is interesting to know if your mamma were at the tail end of the storm (a favourite with GP-P).
The Met Office ‘Cloud types for Observers’ 1982 also does not mention England specifically, and says ‘They are ignored when assessing CH and C’ (cloud classification codes). They are observable before dawn, of course, for early risers (see CAS Calendar for Jan and Feb).
From the ICA you should look out for ‘…periods with a strong, broad, deep and homogeneous westerly to north-westerly current’.
MikeL you must have been on your toes to capture those beauties. Similar ones appeared in the middle of this Weird Weather episode this evening (repeated in the small hours):
