@sainsburys Just bought these chicken breasts reduced to £2.50 but was charged full price (presumably because bottom barcode was not covered).

[Steve Arnold @steverarnold]

@chris15_ace @waitrose Yes! You are correct. Since it was reduced I assumed it was near date and didn’t really look at the month. I assume the staff made the same error as I did since they reduced the price!

[Steve Arnold @steverarnold]

@waitrose I bought this reduced item this afternoon in your Otley store, and it turns out it should have been used by yesterday! 50% reduction doesn’t seem so good now.

@aviationbrk Looks like dust from overrun area after rotating a long way down runway? Those wings look very clean if you look carefully as it lifts off.... 😬

@SkyNews @SophyRidgeSky “Speach”..?!

[Steve Arnold @steverarnold]

@JulieAMcDowall @BBCLookNorth Oh.. sorry! Will check. How long ago?

[Steve Arnold @steverarnold]

@BBCLookNorth @JulieAMcDowall .. and I just noticed you have seen this already! Thought you would probably be on the ball!

🚨 New study! 10 yrs of #China's #AirQuality data shows PM2.5 reductions have slowed recently, while ozone is still rising. More ambitious AQ targets needed to avoid future increases in air pollution excess deaths

@JamesAllanAtmos Thanks @JamesAllanAtmos :-)

[Steve Arnold @steverarnold]

It's that time of year again... widespread elevated #particulate #airpollution across #Yorkshire and eastern England right now. Here is #Leeds Centre (data from @DefraUKAir).

[Steve Arnold @steverarnold]

I would be willing to bet some money on this episode being dominated by particulate ammonium nitrate, as in past springtimes. Perhaps @JamesAllanAtmos and colleagues can show us some real-time #Manchester aerosol composition data?

[Steve Arnold @steverarnold]

The meteorological situation is favouring slack easterly flow from continental Europe. Interestingly, synoptic situation differs slightly from the classic Springtime Pollution episodes of past yrs - i.e. nearby established high pressure over Scandinavia / Baltics.

[Steve Arnold @steverarnold]

@Dunc76 Certainly a very nice Christmas present!

[Steve Arnold @steverarnold]

I really enjoyed @FirstWestYorks Halloween prank of removing the non-stop aspect of the X84 service and converting it to the number 26! You caused all sorts of horror for the passengers! Really effective! Looking forward it getting back to the X84 soon though.

We are recruiting a 3 year postdoc on Climate and Health Attribution at @ICASLeeds as part of the @wellcometrust Global Heat Attribution Project. Closing 6 November. Come join us! @SEELeeds @UniversityLeeds @PriestleyCentre https://t.co/bkN9bm5FH0

@FirstWestYorks Thanks, it did turn up then. By which time I had missed my train at Menston…. #integratedtransportforyorkshire

[Steve Arnold @steverarnold]

@FirstWestYorks Hi. Any idea what happened to the 8am no 34 departure from Otley towards Guiseley?

[Steve Arnold @steverarnold]

@SimonOKing @bbcweather Maybe it would have been worth it to renew that Met Office contract after all …

[Steve Arnold @steverarnold]

@SimonOKing @bbcweather I seem to remember something similar happening before.

[BBC Weather @bbcweather]

Good morning 👋

Unfortunately we've still got technical issues with data on our app and wesbite...it's not actually going to be 7 or 8°C 🤦‍♂️
