If the warmth is spreading in from southern climes how come Kinlochewe was the warmest place in the UK today?

Yet another weathercaster with yet another fancy graphic going on about how we are going to see warmer air spreading up from the continent in the next few days. But they seem oblivious to the fact that warmer air is already here, and the warmest place today in IONA, which Tomasz Schafernaker accidently forgot to make mention of, was Kinlochewe in the Western Highlands. If this can happen here it’s quite obvious that we don’t really need to draw up air from southern climes to see daytime temperatures getting up to 21.5°C or higher, all you need is plenty of sunshine as today’s chart of maximum anomalies shows. It also shows how the haar in the Moray Firth pegged back temperatures, at Tain for instance the maximum temperature was 3.4°C below the LTA whilst not that far away in Altnaharra the maximum was 4.9°C above it.

  1. You are mixing the timing up here – the importing of warm air is developing over the BH weekend – NOT today. W Scotland was warmest today due to the SE flow and presumably some descent / foehn effect – and in fact the warmest place was Achnagart in Glenshiel at 22.1C. What do you mean TS accidentally forgot to mention? Did he say he was going to mention the warmest place?

    1. It’s rather condescending of you to suggest that I don’t know the difference between local warming and the advection of warmer air from the continent. The point I was trying to make in the critique of both TS and especially the SD’s forecasts – in which he started with an unlabelled graphic suggesting that this was happening now – was that we don’t need to import warmer air from France to achieve temperatures of 22°C in the west and north of Scotland. I think the foehn effect was minimal across western Scotland, Altnaharra had no problem reaching 20°C, in fact it might have been a degree or two higher if it hadn’t been for the feed of cold air from the haar in the east. Obviously over the course of time warm advection will start to play a part, but until yesterday temperatures across the near continent have been below average.

      Thanks for underlining the fact that you have full access to daily climate data from the UKMO which the rest of us mere mortals would have to pay for.

      And the only reason that TS didn’t mention the fact that the warmest place yesterday just happened to be in Scotland (and indeed that it was also the warmest day since the 21st of September) was because it didn’t occur in London or the southeast. Don’t forget that this is the same guy that described Stornoway as ‘Nowheresville’ and Leopards don’t change their spots.

  2. The graphic is labelled Monday Bruce.
    I doubt that one high temperature amongst all those islands in W Scotland was produced on the spot.
    Did you look at the Tephigram? Must have been some Fohn warming or/and advection from continental Scotland. Or a dodgy measurement.

    1. Of course I realised that the graphic was labelled Monday but thanks for pointing that out Len. The point of the article as I’ve already tried to explain in a reply to a comment from Julian was that you don’t always need warm air from Spain to explain away a warm day in this country, and Friday was a case in point. To underline that the warmest place today in IONA is also likely to be in the Highlands, and the reason for that isn’t because we’ve imported some warm air from Spain or the foehn effect – but purely the product of strong Scottish insolation.

      Achnagart and Kinlochewe are on the mainland of Scotland Len.

      The maximum temperatures from both stations supported each other and were not in anyway “dodgy”.

      As for tephigrams hadn’t you realised we lost the radiosonde stations at Stornoway and Shanwell over twenty years ago? The one remaining station is in Lerwick 250 miles to the northeast.

  3. Yes, I should have remembered that radiosonde ascents are few and far between now.
    We are a bit spoilt with Camborne down here.
    I suppose adiabatic warming on descent is more usual in a damp westerly than easterly.
    I noticed that there was rather a lot of cloud over west Scotland on Friday as shown by the Terra orbiter at 1105.
    Must have been some breaks later to allow solar warming. Breaks caused by warming on descent.
    Obviously not all dry descent from Highlands which would have given +10 degC.
