I take it that there are individuals from my ignore list turning this into something to do with conspiracies!!! I think I have stalkers. LOL

Well I'm not a stalker. I don't even use ignore lists. Feel free to add me to yours though if you're building up a collection. Your post came over as implying that they might have been giving out duff info.

I don't think either of your thermometers are actually broken though, if they are both showing the same temperature, and I'd be inclined to trust them more than a generalised weather forecast that covers a wide area. If they are showing temperatures at which you'd normally take action to protect something, then take the steps needed to do so. Better safe than sorry as the old adage goes.

I'm also interested in how the met office calculate temps for an area so I can readjust for my specific situation.

They seem to give an average for hourly periods and also a max/min range for a day but that doesn't seem to be a range that covers all places in that area but for a notional place within the area. So I might get -6 but the min temperature is said to be -3

If you don't agree with scarter they assume you are a troll - which is unfortunately quite common amongst those with unusual views.

The list of trolls at the moment includes all energy companies, all insulation companies, the BBC, the met office, and most regular posters here.

36 minutes ago both Glasgow and Prestwick airports are reporting +1 deg

We would normally be a bit warmer than Glasgow and Prestwick (and the forecasts say we should be now). But it's now dropped to -3 at 5pm. Should be 2 degrees according to forecast. 

And at 17.20 Glasgow -1 and Prestwick 0

easy

We have a couple of outdoor thermometers - both in our polytunnel. They've always matched up well with forecasted temps - obviously showing higher temps when the sun is shining.

This past few days our thermometers are reading MUCH lower than BBC and Met are forecasting.  Forecasts are for -3 overnight but we're getting closer to -6. Currently forecasters are showing 1 degree but our thermometers are showing it's STILL -4.2 (despite the sun shining).

I have to say - observations suggest to me that our thermometers are right.

Are forecasters getting it wrong for others? Normally when they get it wrong they adjust as the weather snap continues. But not this time. Trying to establish if I need new thermometers outside. But funny that both (different types) should break.

What part of the country are you in, and what temps outside do you have at say 11am?

I've noticed that the BBC have started saying  "these are city temperatures,  it's likely to be colder in rural areas"  now and then in the late bulletin over the last couple of weeks.  
Could that account for the difference?

I'm trying not to open the outside door to try and keep the heat in so I'm definitely not bothering to go measuring the temperature out there.

I know one thing, and that's enough, it's bloody cold!

I’m in Argyll. 

Outside temperature at 8 am this morning was minus 7. 

The river has frozen over, so I don’t doubt it. 

We definitely have a microclimate in this village  - shaded by hills and forestry. 

Two miles into town and it’s always much warmer.

Met Office and the rest of the world use a standardized thermometer reading inside an enclosure called a Stevensons Screen. They have to be away from all vertical walls and shady areas and sun traps . Unless a home owner has the space to locate their measuring equipment well away from the house it won t be reliable .
Last summer I hung a mercury thermometer in my back garden  from a washing line as a test and it went to nearly 50 c whereas 12 miles away the UK record was broken temporarily at 40 c at Doncaster airport  . I think in the end it went a little bit further to 40.1 c at Heathrow . You have to trust the Met Office ..no one else.They are not "generalised weather forecasts "

Well they are generalised when presented, for precisely the reasons you state.

Their measurements are accurate and standardised, but the forecast of "it'll be 3 degrees in Leeds" is general - and therefore not accurate outside the standard conditions.

And I think that was Scarter's original point - they've noticed that the 'usual' offset between the standard and their local conditions was not holding true at this time and wanted to know why.

Leeds is a large area. One can get a much more accurate local forecast on the main Met Office excellent new website if you enter your postcode in the find a forecast section
